| Evapotranspiration covers are key to minimizing water percolation in waste systems. On potash tailings piles, evapotranspiration covers are important because they may decrease the leaching of brines generated from precipitation erosion. Considering this, the water deficit of four different potash tailings piles covering materials were evaluated using the CropWat model. This study was based on a lysimeter experiment carried out in Heringen, Germany. The experiment consisted of 4 different technogenic substrates made of municipal incineration wastes and coal combustion residues covered with a mixture of perennial grasses. By using the FAO CropWat model, the effective precipitation, crop evapotranspiration, actual evapotranspiration and the water deficit were... |
