The goal is to measure the effects of each user's water use on other users and on the environment, as accurately as possible, and then optimize over the available feasible solutions. Improving water quality. A simple optimization model identifies the cost-minimizing mix of best management practices to reduce the excess of nutrients in a ...
Water extraction (also known as water withdrawal, water abstraction, and water intake) is the process of taking water from any source, either temporarily or permanently, for flood control or to obtain water for, for example, irrigation. [1] [2] The extracted water could also be used as drinking water after suitable treatment.
Agricultural water use is vastly larger than industrial or domestic water use globally and in most countries, therefore irrigation water demand management is an important topic. As with domestic water demand management lack of appropriate data is a frequently encountered problem signalling the importance of measuring water usage at the farm and ...
[13] [30] Time series of WaterGAP total water storage anomalies were used to process and interpret GRACE (Gravity Recovery and Climate Experiment) satellite measurement of the dynamic gravity of the Earth, as for the continents, the seasonal and longer-term gravity changes are to a large extent caused by changes of the water stored in ...
The Dee regulation scheme is a system of flow balancing and quality management along the River Dee managed by a consortium of the three largest water companies [1] licensed to take water from the river, United Utilities, Welsh Water and Severn Trent Water; together with the regulator, Natural Resources

A hydrologic model is a simplification of a real-world system (e.g., surface water, soil water, wetland, groundwater, estuary) that aids in understanding, predicting, and managing water resources. Both the flow and quality of water are commonly studied using hydrologic models.
Fees for water abstraction and discharge exist for example in France, where revenues are significant and are re-invested in the water sector by water agencies established in major basins. In Germany abstraction fees exist only for groundwater and only in some states, and their proceeds go into the general state budget.
