Water stress is the ratio of water use relative to water availability and is therefore a demand-driven scarcity. [1] Water scarcity (closely related to water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. There are two types of water scarcity. One is physical. The other is economic water scarcity.
A typical water quality model consists of a collection of formulations representing physical mechanisms that determine position and momentum of pollutants in a water body. [4] Models are available for individual components of the hydrological system such as surface runoff ; [ 5 ] there also exist basin wide models addressing hydrologic ...
The flushing flow method involves partially or completely emptying the reservoir behind a dam to erode the sediment stored on the bottom and transport it downstream. [7] [6] Flushing flows aim to restore natural water and sediment fluxes in the river downstream of the dam, however the flushing flow method is less costly compared to removing dams or constructing bypass tunnels.
The water that filled the tunnel was a max of 3 feet deep, according to the administrator. Officials responded to "numerous calls for localized flooding across the state," he said. The flooding ...

Thailand is sending almost 1,000 highly endangered tortoises and lemurs home to Madagascar in a landmark victory against animal trafficking, with the first batch on its way on Saturday.
where water tables are shallow, the irrigation applications are reduced. As a result, the soil is no longer leached and soil salinity problems develop; stagnant water tables at the soil surface are known to increase the incidence of water-borne diseases like malaria, filariasis, yellow fever, dengue, and schistosomiasis (Bilharzia) in many ...
