It is increasingly being recognised internationally that integrated catchment management (ICM) is a useful organising framework for tackling the ongoing challenge of balancing sustainable use and development of our natural resource, against achieving environmental goals. The basic principles of ICM (Williams, 2012) are to:
• Take a holistic and integrated approach to the management of land, biodiversity, water and community resources at the water catchment scale;
• Involve communities in planning and managing their landscapes; and
• Find a balance between resource use and resource conservation
ICM is now well established in Australia, New Zealand, and the United States. In Europe the ICM approach has been proposed as being required to achieve effective water and catchment management, and is the approach being promoted by DEFRA for the UK, where it is called the “Catchment Based Approach” (CaBA). The principles and methodologies behind ICM sit well within the context of the Water Framework Directive with its aims and objectives for good water quality, sustainable development and public participation in water resource management. In Ireland it is proposed that the ICM approach will underlie the work and philosophy in developing and implementing future River Basin Management Plans.

The Modeling of dams’ Stability Considering a Seismic Solicitation for the Ta...AI Publications
The activities associated to the mining industry are a major source of risk to the environment, but especially for the local community. In Romania, mining of precious metals (gold, silver and copper) have changed the landscape permanently, having a profound impact both locally and regionally. To determine the behavior of the material inside the tailings ponds dams in case of a major seismic event, two ponds were chosen as study cases, both belonging to Rosia Montana mining region: Valea Salistei tailings pond and Gura Rosiei tailings pond. Rosia Montana mining region is one of the most important Romanian mining regions is the Golden Quadrilateral of the Apuseni Mountains, which it delivered over time significant quantities of nonferrous metals, especially gold and silver. For the two study cases the dams' stability was evaluated by classical methods (analytical and numerical), each method using two hypothesis: static and pseudo-static (seismic). The aim of the study is to monitoring the values of the safety factors when the dams of the tailings ponds are affected by an major seismic event and to observe the potential sliding surfaces through the dam's body, the shear deformations distribution and the total displacements and distribution from the resulted graphics on two random sections chosen for each of the case studies.
Aquifer mapping is a multidisciplinary scientific process wherein a combination of geological, hydrogeological, geophysical, hydrological, and quality data are integrated to characterize the quantity, quality and movement of ground water in aquifers.

Sea level rise and storm surge tools and datasets supporting Municipal Resili...GrowSmart Maine
Why plan for growth and change, when it seems so much easier to simply react?
When there is a distinct and shared vision for your community - when residents, businesses and local government anticipate a sustainable town with cohesive and thriving neighborhoods - you have the power to conserve your beautiful natural spaces, enhance your existing downtown or Main Street, enable rural areas to be productive and prosperous, and save money through efficient use of existing infrastructure.
This is the dollars and sense of smart growth.
Success is clearly visible in Maine, from the creation of a community-built senior housing complex and health center in Fort Fairfield to conservation easements creating Forever Farms to Rockland's revitalized downtown. Communities have options. We have the power to manage our own responses to growth and change.
After all, “Planning is a process of choosing among those many options. If we do not choose to plan, then we choose to have others plan for us.” - Richard I. Winwood
And in the end, this means that our children and their children will choose to make Maine home and our economy will provide the opportunities to do so.
The Summit offers you a wonderful opportunity to be a part of the transformative change in Maine that we’ve seen these gatherings produce. We encourage you to consider the value of being actively involved in growing Maine’s economy and protecting the reasons we choose to live here.
Jason Winner, Conservation GIS Manager for Scenic Hudson presents on the new Sea Level Rise Mapper.
The mapper is a tool for communities and stakeholders to use to create visualizations of future scenarios of sea level rise. With these maps and information, Scenic Hudson is supporting communities' efforts to develop adaptation plans by helping them to:
- create maps of the extent and impacts of inundation and flood zone expansion
- understand the locations of key built and natural resources
- create graphics that illustrate different sea level rise scenarios in specific communities or stretches of the river
- estimate the risks to infrastructure and natural resources and the likelihoods of different inundation events
- develop alternative adaptation scenarios and weigh their cost and benefits with respect to built infrastructure and natural resources
** The Sea Level Rise Mapper can be found on Scenic Hudson's website at: http://www.scenichudson.org/slr/mapper

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

1. Geology and Floodplain Management
A Concept Whose Time Has Come
Kyle House

Mines and Geology
2. It appears that the current system has room for improvement….
Why not improve it with an infusion of reality/geology ?
3. Which statement is most
persuasive?
• Our model output predicts that your
property is within the inundation limits of
our other model’s design discharge.
• Physical evidence indicates that your
property has not been flooded in the last
10,000 years
4. The Role of Geology in Floodplain Management—
Establishing the physical context of flood hazards
• Surficial geologic mapping
– Understand the distribution of flood hazards from
the basis of physical evidence
– Understand related hazards and external geologic
controls
• Paleoflood hydrology
– Extension of flood records in real time over 100s
to 1000s of years.

8. External Geologic controls on flood hazards
• Low sun-angle photo (ca.
1972) accentuates fault scarps
• Faults exert some control on
extent of flood hazard
• Faults and potential for future
offset complicates hazard
management in unforeseen
way
• Indication of need for multi-
hazard management in region

11. Why Evaluate Alluvial Fan Flood Hazards With
Geological Information?
• Alluvial fans are landforms composed of geologic deposits
– They are mappable by virtue of their geologic characteristics
– Active and inactive alluvial fans are distinguishable from the basis
of geological characteristics
• The deposits comprise a stratigraphic and morphologic record of
flood occurrence over a large range of time scales
– A natural, objective event chronology over time scales including
and far in excess of planning considerations.
• Despite its obvious relevance, geologic mapping is relatively
inexpensive and thorough
– all surficial deposits are mappable, not just those associated with
principal drainages.
• Geologic mapping and related studies can provide additional
insights into prevailing hazards and external controls
12. FEMA’s New Three-Step Approach to
Assessing Alluvial Fan Flood Hazards
1. Determining whether the area under study is an
alluvial fan.
2. Identifying which portions, if any, of the area are
characterized by or subject to active and/or
inactive alluvial fan flooding, and
3. Defining the base (1-percent-annual-chance) flood
within the areas of alluvial fan flooding identified
on the alluvial fan
―GUIDELINES FOR DETERMINING FLOOD HAZARDS ON ALLUVIAL FANS‖
http://www.fema.gov/mit/tsd/FT_afgd.htm (1999)
13. Role of Geology and Geomorphology in
the New FEMA Recommendations
Recognizing and • Is the landform composed of alluvium or debris-flow deposits?
Characterizing • Does the landform have a fan-shape?
Alluvial Fan • Is the landform located at a topographic break?
Landforms • Where are the lateral boundaries of the landform?
• These questions are of an entirely geologic nature.
• Detailed surficial geologic mapping addresses each
of these issues as a matter of course.
14. Role of Geology and Geomorphology in
the New FEMA Recommendations
Defining Active and
Inactive Areas of • What parts of the fan are still active?
Erosion and • What parts are inactive but still subject to flooding?
Deposition
• These questions are also of an entirely geologic nature
• Detailed surficial geologic mapping and related field
studies can directly address them as a matter of course.
15. Role of Geology and Geomorphology in
the New FEMA Recommendations
Defining the 100- • Method of analysis: deterministic, probabilistic, geomorphic
Year Flood Within
• To what extent is flooding occurring in the defined area?
the Defined Areas
• Paleoflood Hydrology can greatly improve
confidence in estimates of the so-called ―100-year‖
flood
• Extent of flooding is largely confined to extent of
Holocene alluvial deposits.
– Rely on 10,000 years of flood history or anticipate that the
unprecedented will occur?

hazard extent:
GFP: 39%
RFP: 65%
Error Components
36% of Non-GFP in RFP
23% of GFP not in RFP
• 59% of the piedmont
mischaracterized
• Flood Control structures reduce
extent of the GFP by
approximately 25%
• Geologic mapping costs a
fraction of one flood-control
structure
27. Piedmont Flood Hazard Assessment
• Geologic studies should be first step
• Extent of Holocene alluvium (deposits/surfaces <10,000 yrs old)
as the extent of the geologic floodplain is conservative
• In developed areas, the geological approach is partially
hindsight, but its value is clearly indicated
• Combine geologic data with engineering approach to iteratively
develop the best characterization of flood hazards
• Promote development consistent with topography and drainage
• Disallow development in GFP
28. Geologic Mapping and Floodplain Management
on Desert Piedmonts
• Provides a scientific basis
– Constitutes a test of regulatory models
• Objective
– Basic goal is to understand natural processes
• Comprehensive scope
– Coverage of large areas
• Inexpensive
– Relative to comprehensive engineering analyses (for
which it can provide tighter focus)

30. Paleoflood Hydrology
• The science of reconstructing the magnitude
and frequency of large floods using geologic
evidence
– Physical evidence of floods
• Flood-related sediments and landforms
• Stratigraphic chronology of floods
– Physical evidence of landscape stability
• Sediments, soils, and landforms that preclude flooding
• Paleohydrologic bounds—time interval over which a flood
discharge has not been exceeded

Q97 at Nixon: 21,200 cfs; Qusgs: 42,500 cfs
48. Recommendations
• Geologic studies are essential and should be performed as a
matter of course, not as a novel add-on
– has greatest scientific value early in process
– reality check throughout process
– Can elucidate unforeseen hazards / physical controls
• Alluvial fan hazards
– Extent of Holocene alluvium (deposits/surfaces <10,000 yrs old)
should be considered the extent of the geologic floodplain
• Flood record extension / model testing
– paleoflood information should be collected to corroborate, check,
repudiate empirical/theoretical flood magnitudes when record length is
short and related project is moderate to high-risk.
49. Closing Thought
• Judicious (mandated?) inclusion of relevant geologic
information into the arena of floodplain management is
essential for realistic, effective management.
• Ignorance or dismissal of relevant geologic information is
irresponsible if that information can be demonstrated to bear
directly on the problem at hand.
