1) This document presents evidence through photographs and maps to argue for removing the proposed M-83 highway extension from Montgomery County's transportation plan. It shows how the highway would negatively impact floodplains along Great Seneca Creek and its tributaries.
2) Photographs from April and May 2014 show floodplains absorbing high water volumes during peak flood events, with data from a USGS flood gauge confirming the flood levels. The proposed highway route would cross and degrade multiple forested floodplains.
3) Building the highway would accelerate stormwater flows, increasing downstream flooding and sediment loads rather than reducing them as intended. Removing the highway from plans would protect the floodplains' ability to mitigate floods.
1) Tropical Storm Irene caused record flooding in many Massachusetts rivers, with some peak flows having less than a 0.2% probability of occurring in a given year.
2) The flooding showed that rivers will access their floodplains and erode and deposit sediment in ways that change their channels over time if not prevented by infrastructure like undersized culverts.
3) Massachusetts has established stream crossing standards to maintain river processes and continuity, and these standards are now required under various state permits and regulations. Adhering to these standards helps infrastructure withstand floods like Irene while allowing rivers more natural function.

Modelling of Extreme Conditions for Wave Overtopping at Weymouth Bay
Oliver Way (Hyder Consulting), Tuesday 21 April 2015 at 16:00 - 16:20
A wave model study of Weymouth Bay was undertaken for Weymouth and Portland Borough Council to investigate flooding in the historical centre of Weymouth which is understood to be caused by tidal and fluvial waters overtopping flood defences, groundwater rising above ground level in response to high tides and heavy rain and wave overtopping along the open coast / Esplanade. The wave modelling results in this study are used to provide input conditions to the overtopping calculations which will in turn be used as inputs to the models of overland flow to provide flood extents. MIKE 21 SW was applied to simulate extreme wave conditions with combined extreme water levels. The model domain extends from Chesil Beach in the west to Lulworth Cove in the east. Extreme water level data were supplied by the Environment Agency for Weymouth from the Coastal flood boundary conditions for UK mainland and islands report (Environment Agency, 2012). Extreme wave values were also obtained from this Environment Agency report at offshore locations on the model boundary. Extreme wave conditions were considered for three directional sectors: south west, south and south east. A joint probability approach was applied for a range of return periods and climate change epochs. Wave data were extracted at nearshore locations along the beach front of Weymouth Bay. These data were used as input conditions for wave overtopping calculations (EurOtop) at site specific points along the beach to determine overtopping discharge rates along the beach front.

Extra moorings and facilities are needed on London’s waterways to help address hotspots of overcrowding as increasing numbers of Londoners are turning to living on the water, our new report says. With house prices and rents rising to record levels in London, the report says more people are choosing to live on a boat as a more affordable option. Yet, the number of moorings and facilities, such as water supply and waste disposal, has not increased in line with demand. We set out a number of recommendations that we think can help address the overcrowding and improve relations between the different people who use the waterways.
The document describes key terms and concepts related to river systems, including:
- The three courses (upper, middle, lower) that rivers pass through as they travel from their source to their mouth.
- Key landforms and features associated with rivers like tributaries, meanders, and flood plains.
- Erosional processes like hydraulic action, abrasion, and solution that shape river valleys and landscapes over time.
- Flooding impacts on people and the environment as well as methods for predicting, preparing for, and managing floods.
The document summarizes key aspects of the hydrosphere including the hydrologic cycle, oceans, ocean water movement, permanent ice, surface waters, and underground water. It explains that most water exists in oceans and a small fraction cycles through evaporation and precipitation. Ocean waters have varying characteristics and move via tides, currents, and waves. Surface waters include lakes, swamps, rivers and streams, while underground water exists in aquifers below ground. Human activities have significantly impacted both surface and subsurface waters.
This document provides an overview of coasts and coastal processes. It begins with an introduction to the topics that will be covered, including the syllabus, case studies, coastal processes, and exam technique. Case studies include the Holderness Coast, Flamborough Head, and Spurn Point. Coastal processes such as hydraulic action, abrasion, attrition, and solution are explained. Exam advice is given around answering 6-marker questions by explaining coastal landforms and processes in a structured sequence.
Private submission as interested community member calling attention to Arden precinct's vulnerability to sea level rise and premature lock in of a turnback at West Footscray.
The document discusses considerations for developing port development scenarios through a series of workshops. It outlines the key topics to be covered, including demand forecasting, capacity assessment, scenario formulation and evaluation, financial analysis, environmental assessment, and cost-benefit analysis. An agenda is provided for the first day focusing on port master planning and scenario development. Challenges facing existing ports are then reviewed, such as increases in cargo volumes, vessel sizes, and changes in cargo types. Functional requirements for developing new ports and accommodating different trade types are also examined.
Coastal sediments are formed by the breakdown of rocks into grains from waves, currents, and tides. In tropical areas, shells and skeletons of marine organisms create white sand beaches, while volcanic ash and lava produce black sand beaches. Coastal sediments come from coastal erosion, rivers, glaciers, storms, tidal currents, and changes in water levels. Sediments are classified as clastic from rock erosion or biogenic from marine organisms. They are also cohesionless solid grains or cohesive clay minerals. Sediment transport along the coast includes longshore drift parallel to the shore and onshore-offshore movement perpendicular to the shore. This shaping of sediments forms coastal landforms such as spits, tombolos,
This document provides details on the qualifications and experience of Philip Styles, an engineering geologist with over 35 years of experience. He has extensive experience in geotechnical investigations and projects involving dams, tunnels, slopes, foundations and contaminated sites. The document lists his professional affiliations and areas of expertise, appointments with various engineering firms, publications, project experience, and qualifications.
Clifton Hasegawa wrote a letter to Commissioner Maria Damanaki of the European Commission regarding her remarks on Arctic futures and global partnership for the Arctic. Hasegawa advocates for a cautious approach to oil exploration in the Arctic that considers environmental impacts. He is concerned that increased deepwater drilling could disturb undersea plates and slopes, potentially contributing to climate change through seismic activity. The impacts of such drilling could have far-reaching consequences around the world given the connections between tectonic plates and volcanic activity.
This document summarizes an academic visit to coastal areas in northern Peninsular Malaysia. The visit included observing coastal erosion, structures like breakwaters and groynes, and environmental conditions. Samples were collected to analyze beach material and erosion levels. The objectives were to assess shoreline conditions, observe protection structures, and identify successful mitigation methods. Common coastal protection measures discussed include breakwaters, groynes, revetments, and jetties.

Slide deck for the third of ongoing series of presentations looking at water's planet-shaping role and barriers to its recognition within knowledge systems submerged in human language.
The document discusses several hypotheses that were initially dismissed but later gained acceptance:
- Plate tectonics was proposed in the early 20th century but not widely accepted until more evidence was discovered 50 years later, showing continents could move.
- The existence of an aether to transmit light was proposed by Newton and used in Maxwell's equations, but failed to be detected in experiments. Einstein's theory of relativity explained light without an aether.
- Lamarck's idea of acquired traits being inherited, accepted for millennia, was dismissed due to experiments failing to prove it. However, epigenetics shows environmentally induced reversible heritable traits without DNA change, partially validating Lamarck.

This document provides a summary of Tony Smith's quarterly huddle on 27 February 2022, covering five crazy years and motivating the group for the final quarter. It includes updates on various environmental projects, site visits, and community events focused on protecting local creeks, rivers, and other natural areas in Victoria.
OverFlow Chart Introduction and Application to Gateway DrugsTony Smith
Presentation Slides from Melbourne Emergence Meetup 11 November 2021 examining three emergence-superveience relationships centred around the Accelerating Abstraction of humans from Industrialised Apex Predator in the biosphere to ever more Documented Consumable in the map of legal fictions.
- The document summarizes lessons learned from a major flood that occurred along the Cumberland River in early January 2021, mobilizing large rocks and depositing them in intertidal waters while trapping silt and gradually turning wetlands into dry land.
- It discusses the failure of delayed rainfall observations to trigger emergency warnings, and the broad catchment and narrow gorge creating a delay between rainfall and peak flooding.
- The self-organization and mutual assistance of the camp/visitor community during the middle of the night flood is also summarized, as well as the lack of contextual awareness from responding police and SES volunteers initially.
Images (pics, maps and covers) drawn from Kororoit Institute submission to parliamentary inquiry into Ecosystems Decline in Victoria, with minimal commentary aside from section headings and recommendations, providing context for discussion of where we take this from here, both the global task of insisting on the urgent need for humans to work with rather than against until now dangerously suppressed ecosystems, and the local task of working with structures of our colonial political economy to ensure the tide is well and truly turning.

December 2019 presentation to Melbourne Emergence Meetup in the scope of ongoing Supervenience project series and as corollary to November's presentation re human infrastructure projects the group has taken an interest in. Includes pictures from recent visits to Stony Creek toxic fire site and Mud Island.
Many people are aware of something of particular interest to them which conventional wisdom gets badly wrong but assume that one thing is all that really needs to be fixed while the status quo is otherwise fine. Once you escape your silo and start seriously looking around, it becomes obvious that most things you take for granted are pretty much stuffed too. This presentation to CVAF highlights a few of them and argues that adversary systems are no longer fit for purpose.
Presentation to Melbourne Emergence Meetup 12 September 2019 providing further context for Supervenience Project, interleaving four decades of awareness development with one of local activism and digital photography. Doesn't quite achieve declared aims of bridging Too Funny for Words with Accepting Cosmological Responsibility, but useful starting point nonetheless.

The document summarizes Tony Smith's presentation on self-organized criticality. Some key points:
- Self-organized criticality describes how dissipative systems with extended degrees of freedom can evolve toward a minimally stable critical state through small, frequent disturbances that follow a power law distribution.
- Bak et al's 1987 paper that introduced this concept has been shown to be relevant to many natural phenomena like sandpiles, earthquakes, wildfires, etc. that maintain a critical balance.
- Smith's presentation applied self-organized criticality to better understand everyday human behaviors and systems, examining universals, animals, civilization, and modernity in terms of approaching critical thresholds.
- Reaching critical states

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Medical image analysis has witnessed significant advancements with deep learning techniques. In the domain of brain tumor segmentation, the ability to
precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.

2. Priorities this evening?
• Preparations Pretending to be Policies and Politics
• Pristine Port Phillip Mythology and Bromance
• Precarious State of Pretentious Freight State
• Projections and Uncertainties of Sea Level Rise
• Providing Capacity to and beyond Drysdale and Baxter
• Practicalities from Arden-Macaulay to Westernport
4. Failure of policy and politics to comprehend
likely trajectory of sea level rise
Lesson from Narooma:
Erosion and Deposition
processes do not respect
human-defined shorelines
5. • Submitted SlideShare link to our February presentation with
notes to Draft Port Phillip Bay Environmental Management
Plan 2017-2027 process and received encouraging response
confirming Dan Ierodiaconou’s involvement
• Late April dropped in at Moolap Coastal Strategic Framework
session which added introduction to OurCoast Bellarine-Corio
Bay process that references considerable technical work
including Neville Rosengren and Great Sands
• Found another interested DELWP person at Transport Camp
in October and copied them the information
• As yet nobody is chasing us for more, seeming to be acting as
though their job is to apply romantically coloured bandaids
6. • The 0.8 metres by 2100 furphy refuses to die in politically
mandated assumptions, even when it is admitted that it was
from another millennium and should be treated as a minimum
• More interesting is 0.2 metres by 2040, maybe not enough to
scare the cats unless they see where it must go from there
• No end of details of both historic rates and current risk areas
continue to be identified by those not buying denialist line
• The deep problem that political determinations can’t cope with
is that no matter what the date and what the depth, sea level
will still be rising and most likely still accelerating because of
components that are already locked into the system, so there is
no point planing for just those mandated levels
7. Need to challenge romantic delusion about
pristine Port Phillip, natural fixations
Variety of bird species exploit
permanent high flow litter
trap on Moonee Ponds Creek
below Racecourse Road
8. • Port Phillip refilled only 1,000 years ago and so is still young
in ecological terms and anything but a pristine environment
• Viewed in the light of historic records of the marine invasion
of Zuiderzee and charts from early British explorers, shallow
erosion of Nepean Bay Bar has likely been a gradual process
• Since the unauthorised invasion by Post Phillip Association
from Tasmania in 1835, the bay floor has been trashed 3 ways
• dredging oyster and mussel reefs to make lime for concrete
• dredging shipping channels
• dredging for scallops
• together leaving a trashed bottom unseen by surface admirers
9. • Similarly, the most committed of environmentalists can form
attachments to their images of pristine conditions somehow
immune from the passage of time
• The reality is that most life forms adapt to change so long as
there continues to be somewhere and somehow for them to,
but on a different timetable to news, politics and profit reports
• Werribee Sewage Treatment Farm is the state’s most
significant bird site. Trin Warren Tam-boore wetland tops
species counts. Both are in areas which have historically been
bird habitat, but both are much modified, yet still found
• Many species seem comfortable in areas that offend human
aesthetics, maybe because humans mostly keep away
10. Increasing evidence it was and is not smart to
aspire to be THE Freight State
Circuitous Webb Dock freight
line adjacent Lorimer Street,
opened 1986, ceased
operation 1992, closed 1996
11. • The 2008 round of channel deepening remains contested by
those who opposed it. Is it that, the to date minor sea level rise
or a combination that is accelerating bayside erosion?
• Containers are transported “around the equator” on very deep
draft vessels then transferred, in Australia’s case, in Singapore
to more moderate draft vessels which typically visit all five
mainland capitals’ ports, so the depths have needed to be
consistent between the five with no incentive to go deeper
• Victoria remains a battleground between standard gauge and
broad gauge rail with ports often using dual gauge at the end
• Current locations of logistics hubs, container storage and ports
are mostly poor candidates for freight rail separation
12. • It may not be very wise to make projections extrapolating
business/growth as usual deep into the future
• As even WWII fades from living memory it may be useful to
reflect on the recency of many underpinnings of modern life
• While blatant vested interests obstruct recognition of resource
constraints and unintended consequences of technologies,
“finite planet” is more than a truism
• Concurrent knowledge explosion shows interconnectedness of
living systems, encouraging attempts at moderation
• Before the globalised world starts to spiral out of control,
should Australia reduce its dependence and become an ark?
13. Continuing updates to projections for climate
change and sea level, reality at high end
Last day of November heat
draws late afternoon crowd
to Port Noarlunga Jetty
14. • Despite the noise of the anti-science crowd on their scientific
devices and the desperation of declining media to boost any
hint of controversy, climate science still tackles hard questions
• Taking the planetary temperature is not like taking the local
temperature, but we are identifying variations in circulation
patterns which have predictable impacts on best estimates
• If we could account for all sinks and sources, any composite
measure of global thermal energy would be rising year on year
• Challenge to find measure to quickly detect going off curve
• Various feedback loops have triggered or are threatening to,
but as yet we are mostly seeing signs, not inescapable signals
15. • Scientists are ever more accurately identifying signals from
geological records of sea level and associated causal factors
• Other scientists are identifying destabilisation risks for all
three major ice sheets: Greenland, East and West Antarctica
• Never enough scientists are studying the interacting roles of
fresh water, soils, forests, agriculture, urbanisation, life itself
• In the process they are finding that aridity from Australia to
the Sahara may follow early blossomings of human agriculture
• Measures of recent sea level rise are still too small and multi
factorial to give a lot of confidence as to where we are on the
curve, but once we do, we know turning back won’t get easier
16. Challenges for transport network evolution to
service barrier from both ends
Six tracks at Geelong Station
are pointed into single track
1876 tunnel too low to take
full height container freight
17. GeelongEasternBypass
Indicative Nepean Bay Bar ApproachFormer Drysdale Queenscliff Railway
Skyrail Breakwater-Drysdale avoids level
crossings and Moolap Lowland inundation
Geelong Eastern Bypass via Point Henry will
distribute Melbourne metropolitan traffic
Most of route Drysdale-St Leonards is above
20 metre contour so should be less hurried
Identifying route across Nepean Bay Bar
ahead of significant sea level rise is critical
Construction of foundations to most of that
route may reduce tides and erosion in north
Locks should enable operation of Webb and
Swanston Docks while project completed
18. Mornington Peninsula Freeway ReservationDundasStreet
CanteburyJettyRoad
Bay South Floating Port
Drawing acceptable line in the sand hills will
be a big challenge for local community
Need an impervious wall as foundation for at
least 20 metre elevated transport routes
Can’t try to be prescriptive at this stage, just
set out constraints and essential components
Route from beyond Boneo Road to Baxter has
been thoroughly canvassed by Rob Whitehill
His Peninsula Rail Plan is primarily passenger
so East-West-Port freight needs to be added
Assume Baxter-Dandenong and more will be
needed to distribute metropolitan traffic
19. Sorrento
• Zone: 4
• Platforms: 2
• Staff level: Staffed full-time
• Melway Ref: 156 K7
Although it was once thought impossible to run rail
beyond Rye station, the recent controversy over the Skyrail
project between Caulfield and Dandenong stations has
revealed the possibility of running elevated rail beyond Rye,
to Sorrento. The line would run along the reserve for the
Mornington Peninsula Freeway extension, and then alongside
Melbourne Road, elevated for its entire length except for parts
of the freeway extension reserve where the line would run
along the ground, and when it crosses Melbourne Road
opposite Tarakan Street, where it would go under the road in
order to maintain level track.
Sorrento station itself would be located above Ocean
Beach Road, just a short walk away from existing carparks,
which would be connected to the station by a ramp.

20. Closer look at particularly vulnerable locations
from Macaulay to Westernport
Accessible sea level monitoring
where Moonee Ponds Creek
flows into tidal Railway Canal
outside Macaulay Station
21. Areas within Land Subject to Inundation
Overlay are prime development targets
Focus remains on floods coming downstream
but adjacent tidal streams sea level the issue
Concerned about vulnerability of major
infrastructure proposed for Arden-Macaulay,
City of Melbourne enlisted Melbourne Water
Expert witness to West Gate Tunnel Inquiry
and Assessment Committee showed much
wider vulnerability across the flood plains
Healthy Waterways Catchment Collaborations
for Moonee Ponds Creek and Maribyrnong
West Melbourne Lagoon abused by industry
but can strike back hard with sea level rise
22. Wider closure of Westernport not practical
but large area at risk from north arm alone
Significant tidal channel wraps northwest
corner of French Island with smaller one
between northeast corner and mainland
If these channels are closed an impervious
foundation could link highlands via Island
Try to preserve Island’s ecological isolation
Port Phillip and Westernport catchments are
separated with a low point above 25 metres
elevation near Pound Road, Clyde North
Establishing impervious foundations that can
be raised to 20 metre elevation offers medium
term confidence in greater Melbourne region
