Applications of numerical simulation to the sedimentation in the Sanmenxia reservoir and the Lower Yellow River
The non-harmonious combination of insufficient water and excessive sediment causes many problems for the Yellow River. These problems include severe sedimentation in the Sanmenxia reservoir, the rising of the water level at Tongguan for a given discharge (1000 m³/s) and the rising of the bed level of the Lower Yellow River (LYR). How to lower the Tongguan Water Level (TGWL) and alleviate ...

New planning technique to master the future of water on local and regional level in Ukraine
A new water resource planning technique was developed for regional and local levels of water management in Ukraine. For this purpose, methodology, methods and tools, as implemented in the Water Scenarios for Europe and for Neighbouring States (SCENES) project, were studied and adapted to the specific situation of the Crimea pilot area in the South Region of Ukraine. For testing of the new ...

Aral Sea partial restoration. I. A Caspian water importation macroproject
A comprehensive control strategy to partially recreate the Aral Sea involves several hydrological factors: overland pipeline conveyance of Caspian Sea water deposited into the Aral Sea Basin; overland pipeline conveyance of Aral Sea brine deposited into the Caspian Sea; compensating overland pipeline importation of Black Sea water to the Caspian Sea. Effects of hydrological management of the Syr ...

Water-level regulation for freshwater management of Bosten Lake in Xinjiang, China
The Bosten Lake is the largest inland freshwater lake of China, in which water level and salinity fluctuate due to the imbalance between inflows and outflows under climate change and anthropogenic activities. This paper employed system dynamics as an effective methodology to grasp the regulation rules for sustainable freshwater management of the Bosten Lake. Results show the following. (1) ...

Integrated Water Resources Management: contrasting principles, policy, and practice, Awash River Basin, Ethiopia
Integrated Water Resources Management (IWRM) has been a dominant paradigm for water sector reform worldwide over the past two decades. Ethiopia, among early adopters, has developed a water policy, legislations, and strategy per IWRM core principles. However, considerable constraints are still in its way of realization. This paper investigates the central challenges facing IWRM implementation ...

Complete Water Balance for Rijnland Water Authority - Case Study
Complete Water Balance for Rijnland Water Authority In May 2017, the Rijnland Water Authority started using measuring equipment that helps provide better insight into the impact of climate change on water management. This involves three Eijkelkamp Smart Lysimeter measuring stations, which in addition to evapotranspiration data also provide data about the amount of precipitation, wind and soil ...

Aral Sea partial restoration. II. Simulation of time-dependent processes
Three operational scenarios produce water levels stabilised at 28.9, 27.2 and 25.7 m. A macro-engineering solution is considered. Increased runoff from Syr Darya and other freshwater sources raises the Aral Sea level by 1.4-3.5 m. Depending on the scenario, the Aral Sea returns to its 2005 elevation. Caspian Sea water importation, at flow rates of 14 km³/year leads to Aral Sea stabilisation at ...

Data management for integrated water resources management in Central Asia
Information technologies can act as technical artifacts and can facilitate stakeholder communication, supporting decision making in a complex societal context. The water sector is one such example where limited water resources are threatened by climate change and growing competition for resources between sectors, regions and countries. Attempts to improve water governance and management through ...

Does organising matter? Tracing connections to environmental impacts in different housing estates
Much of the research on buildings and the environment is of a technical-economic nature. But so far, this has not led to any great changes in practice. This article brings organising into the research agenda: Does organising matter for the environmental performance of buildings? If so, how? This question is investigated by a comparative analysis based on an empirical approach. Two housing ...

Case study - Continuous discharge monitoring in Mecklenburg - Germany
The Wallensteingraben was originally constructed as a channel and is almost 20 km long. In the context of implementing the European Water Framework Directive, goals include improving ecological passability. At the same time a measurement site for the continuous monitoring of discharge quantities was installed. Products used include OTT SLD, OTT CBS and OTT LogoSens. Monitoring Solution ...

DelAgua Kit Case Study - Comet-ME Testing in South Mount Hebron Region
Comet-ME is an Israeli-Palestinian NGO providing sustainable off-grid energy and water services to rural Palestinian communities in the South Mount Hebron region of the occupied Palestinian territories. The local Palestinian communities are not connected to the water grid and people depend on seasonal rainfall for their water supply, harvesting the rainwater in cisterns. Come-ME's water ...

Spatiotemporal groundwater level forecasting and monitoring using a neural network–based approach in a semi arid zone
Forecasting the groundwater level (GWL) of an aquifer is one of the most important tasks in hydrogeology. Such forecasts prove vital to develop better exploitation strategies of water resources and to carry up–to–date groundwater monitoring. In this paper, an artificial neural network (ANN)–based approach, which was based on linear regression model, is presented to simulate and predict both ...

Monitoring River Back-up - Case Study
A research team working with a municipal client contacted StormSensor because they wanted to calibrate a model for a basin study in a flood- prone area along the Mississippi River. A preliminary four-Scute™ network was installed in September 2019. A few months into the study, sudden reverse flows and rapid increase in depth were detected across all monitoring points. After some quick ...

Many Indian Cities May Soon Run Out of Water
National policy commission is guiding states with sustainable development goals The Indian government’s prestigious National Institution for Transforming India policy commission (NITI Aayog) has released a report that warns that as demand continues to skyrocket, 21 Indian cities will run out of groundwater by 2020 without adequate countermeasures. By 2030, demand is expected to increase ...

Why is digital transformation key for the water sector in Saudi Arabia?
Digital transformation can be defined as the optimization of company processes via new technologies (Big Data, IoT, etc.) to improve operations and the user experience. In water utilities, this involves the use of advanced technological systems to monitor and control processes throughout the entire water cycle, from water collection to its discharge back into the environment. Although different ...

Study: Water Use in Concrete Production Higher Than Expected
Researchers uncover areas where better management may mitigate high water use Although many environmental impacts of concrete production have been well studied, little research has been dedicated to just how much water it uses. But, a study published in the journal Natureseeks to quantify the impact of concrete production on global water withdrawals, and it makes some dramatic conclusions and ...

Sensors provide Iowa flood warnings
To create the world’s most sophisticated flood monitoring and forecasting system, the Iowa Flood Center (IFC) uses more than 200 Senix ToughSonic 30 and ToughSonic 50 ultrasonic sensors to measure water levels in streams across the state. Data collected from the sensors are automatically sent to the Iowa Flood Information System (IFIS), where the real time monitoring information ...

Why Cities need to design for circular water management
The biggest challenge facing the water industry is making supply meet demand, especially in cities with explosive population growth. Water shortages are a very real threat, with freshwater supplies in the UK estimated to fall by more than one billion litres by 2024. Additionally, there is a lot of waste. Globally, 80% of wastewater flows back into the ecosystem without being treated ...
