The California Central Valley Groundwater-Surface Water Simulation Model (C2VSim) simulates the monthly response of the Central Valley’s groundwater and surface water flow system to historical stresses, and can also be used to simulate the response to projected future stresses. C2VSim contains monthly historical stream inflows, surface water diversions, precipitation, land use and crop acreages from October 1921 through September 2009. The model dynamically calculates crop water demands, allocates contributions from precipitation, soil moisture and surface water diversions, and calculates the groundwater pumpage required to meet the remaining demand.

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.

FAST Danube – Hydraulic and sediment transport modelling with MIKE 21 FM mode...Stephen Flood
The objective of the FAST Danube project is to propose navigation improvement solutions on the Romanian-Bulgarian common sector of the River Danube. The proposed technical solutions would ensure that the required navigation parameters (navigation channel width, depth and bend radius) are achieved at the specified lowest navigation water levels. This would enable safe navigation and transport activities on the Romanian-Bulgarian common sector of the River Danube throughout the entire year.
MIKE 21 FM hydrodynamic and sediment transport models have been developed to help understand the behaviour of the river and the reasons for the changes in river morphology, which result in constraints to navigation at the critical locations. The MIKE 21 FM models are required to support the selection of solution options by providing a first assessment of the relative performance of navigation improvement solutions in maintaining the required navigation fairway parameters. In addition, the MIKE 21 FM models will also provide outputs to support the assessment of the potential impacts of the solutions on navigation conditions and on the river environment. Furthermore, the models will also be used as tools in future management of the river in the project area.
This presentation will focus on the numerical modelling conducted with the MIKE 21 FM model within the FAST Danube project, and how the MIKE 21 FM models are used in the development of navigation improvement solutions and options appraisal process.
Presented at the DHI UK Symposium 2018.
Seismic attributes are being used more and more often in the reservoir characterization and interpretation processes. The new software and computer’s development allows today to generate a large number of surface and volume attributes. They proved to be very useful for the facies and reservoir properties distribution in the geological models, helping to improve their quality in the areas between the wells and areas without wells. The seismic attributes can help to better understand the stratigraphic and structural features, the sedimentation processes, lithology variations, etc. By improving the static geological models, the dynamic models are also improved, helping to better understand the reservoirs’ behavior during exploitation. As a result, the estimation of the recoverable hydrocarbon volumes becomes more reliable and the development strategies will become more successful.

DAMMED IF YOU DO, DAMNED IF YOU DON'T:
Global sea level rise and the consequences for the built environment
In light of the impacts of recent natural disasters, including the cases of Hurricane Katrina and Andrew, the need is evident for a proactive and transparent Engineering Policy approach to protect the coastal built environment. This response is especially critical considering climate change and the potential for global rise in mean sea level accompanied by increases in storm intensity and frequency.
This talk presents our simulation of the design and construction response required to protect the world's major ports from a significant rise in mean sea level. This simulation was developed through engineering design, GIS (Geographical Information System) Science, hydrologic modeling, and time scheduling based on a comparison of the project requirements to the current industry capacity. While our preliminary results show that the cost of protecting only the 177 most significant ports in terms of economic value (amongst nearly 3,000 major ports total) will be significant, our analysis also shows that the most troubling aspect of an engineering and construction response to sea level rise is the requirement for materials. This will cause dramatic shortages in sand, gravel and other materials, which will ripple through the entire construction industry.

This presentation was given as part of the EPA-funded Catchment Science and Management Course focusing on Integrated Catchment Management, held in June 2015. This course was delivered by RPS Consultants. If you have any queries or comments, or wish to use the material in this presentation, please contact catchments@epa.ie
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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
