The six heavy metals (Cu, Ni, Pb, Zn, Mn, and Cr) in surface runoff of different ecological restoration areas were strongly related to each other, and were significantly related to the TSS. Keywords: Heavy metals; Manganese tailing wasteland; Nutritional pollutants; Surface runoff; Vegetation restoration.

15/11/2019 · Niu et al. (2016) studied the runoff pollution reduction ability of each layer of permeable pavement individually and found that the optimal thicknesses of the bedding layer and sub-base layer were 5 cm and 20–30 cm, respectively, to assist in the engineering design of a permeable pavement.

29/01/2018 · During tailing stockpiling, surface runoff and atmospheric dust were experienced in tailing wastelands, which bring forth a series of heavy metal pollution of soil, surface water, groundwater, and other eco-environments (Daldoul et al. 2015; Souissi et al. 2015). Therefore, it was urgent to solve the problem of ecological restoration and the ...

16/12/2002 · Runoff may be classified according to speed of appearance after rainfall or melting snow as direct runoff or base runoff, and according to source as surface runoff, storm interflow, or groundwater runoff. 2. The sum of total discharges described in (1), above, during a specified period of time. 3.

Abstract. Urban development dramatically alters a drainage system by landscaping, changes in surface cover, and addition of stormwater handling systems. Increased and warmer runoff from impervious surfaces into streams can lead to a degradation of habitat for coldwater fish. For the projection of thermal impacts of new land development projects, ...
