This document discusses the Hudson Estuary Watershed Resiliency Project, which aims to build resilience to extreme weather and climate change in the Hudson Estuary watershed. It provides information on watersheds and flooding, including that increased precipitation and land use changes are contributing to more frequent flooding. The project focuses on educating communities on better understanding their local streams and implementing solutions to reduce flooding impacts.
Origin of water salinity in Annaba aquifer system, North-Eastern Algeria | JBESInnspub Net
The Annaba area hosts in its underground a water potential of great importance. In fact, it is one of the Algerian plains where groundwater is subject to over-pumping. Moreover, the expansion of farmlands and the development of the neighboring agglomerations required a massive pumping of water, thereby leading to the change in hydrodynamic regime of groundwater and to the degradation of its quality. On the basis of boreholes and physicochemical data, the three major factors responsible for the evolution of chemical quality of water observed at the aquifer were identified: (1) mineralization due to natural and anthropogenic processes (responsible for the increase in the contents of chlorides, sodium, calcium and magnesium), (2) the oxydoreduction conditions due to the passage of the water table from an unconfined aquifer or even semi-confined to a confined aquifer (responsible for the reduction of nitrates and (3) pollution of groundwater by nitrates in areas where the water table is shallow and in the absence of a protective clayey cover.
Over the last decade, demand for spring management has increased as traditional spring sources have started drying up or becoming contaminated. In response, communities, NGOs and state agencies began dedicated spring protection programmes. In the Himalayas, the State of Sikkim and organizations such as Central Himalayan Action and Research Group (CHIRAG) and People Science Institute (PSI) started identifying and protecting spring recharge areas around 2007. The difference between these programmes and many other previous efforts is that they went beyond supply-side improvements to focus on the use of hydrogeology to map springsheds for targeted interventions.
The Advanced Centre for Water Resources Development and Management (ACWADAM), a research and capacity-building organization comprised of hydrogeologists and other experts began lending their expertise and building capacity of stakeholders. ACWADAM provides technical support, training and materials in hydrogeology to all network partners as well as others in India and the region. Similar programmes began independently in most of the mountain regions of India. Arghyam, a funding organization that was supporting many of these programmes, noticed that these disparate initiatives shared commonalities despite geographic diversity. They thus organized and funded a meeting of these various organizations in June 2014, and the Springs Initiative was born.
The springs initiative aims to tackle the current water crisis and to ensure safe and sustainable access to water for all, by promoting responsible and appropriate management of aquifers, springsheds, and watersheds and conserving ecosystems in partnership with communities, governments and other stakeholders.
This presentation has been developed as a part of the springs initiative to promote an understanding of springs and their role in mountainous areas.

ICLR Webex: The role of groundwater in flooding (September 24, 2014)glennmcgillivray
On September 24, 2014, the Institute for Catastrophic Loss Reduction held a workshop entitled 'The role of groundwater in flooding' with Cathy Ryan from the University of Calgary.
Cathy Ryan is a Professor in Geoscience at the University of Calgary who is trained as a geotechnical engineer and hydrogeologist. She has been researching groundwater/river interaction river-connected alluvial aquifers in the Calgary region for more than a decade. Her interest in the role of groundwater in flooding was sparked after the 2005 Calgary floods when anecdotal information collected in a door-to-door survey of residents in neighbourhoods around Calgary's Elbow River suggested groundwater inundation (as opposed to overland flooding) caused a significant amount of the economic damage to homes. It is Dr. Ryan's view that groundwater flooding is under-recognized but can be easily monitored and understood.

Extreme weather is becoming more common in our region. Flood events can impact human health and safety, and result in substantial costs to property and infrastructure. Geared toward municipal decision makers and concerned citizens, this forum provides on-the-ground examples of flood resilience strategies that can help Hudson Valley communities minimize risks while conserving financial resources.
Presentation by Gregg Swanzey, Director of the Office of Economic Development and Strategic Partnerships, City of Kingston and Libby Murphy, Climate Outreach Specialist,
Hudson River Estuary Program, NYSDEC for a flood management forum hosted by the Cary Institute of Ecosystem Studies in Millbrook, NY on May 4, 2013.
Numerical modeling in support of the characterization and remediation of impacted sediments can be a challenging task, particularly in environments where multiple physical processes influence sediment fate and transport. The interaction of various controls is particularly complex in estuarine settings, where riverine input, water levels, waves, and other coastal processes combine to create a seasonally dynamic environment. Modeling of such environments requires a comprehensive and integrated approach such that the effects of each process can be assessed individually, as these processes can be allowed to interact to reproduce the natural environment as faithfully as possible
Approach and Activities
This contribution describes the development and calibration of an integrated Delft3D numerical model that includes flow, sediment transport, wave processes, and vegetation. The model boundary conditions are based on data collected during a comprehensive field program. Field data were also used to calibrate various model input parameters (such as bed and vegetation roughness). The model was used to understand erosion and deposition during both low and high flow regimes, and thus to aid in understanding important controls on sedimentary dynamics during these predominant regimes.
Results and Lessons Learned
The integrated numerical model predictions capture important sedimentation, erosion, velocity, and water level patterns. Model predictions indicate that during periods of low riverine input, velocity patterns and sediment transport associated with periodic water level changes dominate. During riverine flood conditions flow and sedimentation patterns are controlled by the river itself. Integrated modeling of this setting, including calibration to field data provides a valuable tool for assessment of future conditions, and thus for remediating impacted sediments.

Russian anarchist and anti-war movement in the third year of full-scale warAntti Rautiainen
Anarchist group ANA Regensburg hosted my online-presentation on 16th of May 2024, in which I discussed tactics of anti-war activism in Russia, and reasons why the anti-war movement has not been able to make an impact to change the course of events yet. Cases of anarchists repressed for anti-war activities are presented, as well as strategies of support for political prisoners, and modest successes in supporting their struggles.

Flowing Water Moves Sediment
• As water moves over the land it picks up sediment,
forming the stream channel
• Streams create and maintain their shape and size
themselves, a result of:
• Volume of water
• Amount of sediment
• Type of sediment

Balancing Act
• Streams are said to be in equilibrium or

Flood Resiliency ~ Take Home Messages
• Streams move water & sediment.
• Streams move in predictable patterns
across the land.
• Streams are dynamic systems that
respond to disturbance.
• Human infrastructure & actions can
cause stream disturbance.
• Recent advances provide tools for
communities to work with streams.
• Communities find pro-active solutions to
flooding.
