Lakes, ponds, and major rivers were identified as ecological sources, and the ecological source was divided into four grades. Spatial data of WT depth, multiple buffering data of surface water bodies, and spatial density data of surface water bodies were used to construct resistance surfaces. The...
Part of the runoff water forms temporary ponds (Figure 2d) up to the level of the spillways when the retention capacity is reached. As Abdelli et al. explain [6], it can be easily estimated that for a Jesr with a 50 cm-high spillway and a surface of 200 m2 (thus forming a ...

Indeed, according to US EPA’s assessment (https://ofmpub.epa.gov/waters10/attains_nation_cy.control), 55.5% of streams and rivers, 70.3% of reservoirs and ponds, 78.3% of bays and estuaries, 88.9% of coastal shorelines, and 53.4% of wetlands are currently impaired and, as a result,...
