In Romania before 1990, over 600 hydro-power plants were built with dams and lateral dikes made of local materials. In order to be completed as soon as possible and with material savings, the protection screens were improperly executed. In many cases there is no continuous protection screen along the dam and in its vicinity, but only from place to place, intermittently. The same problem is with the lateral dikes of the lakes. In these conditions, at the hydroelectric power plant commissioning, the infiltration imm...

Optimum exploitation of the agricultural lands in the presence of polluted aquifers by surface sources requires close monitoring of the groundwater level in both periods of massive rains or, on the contrary, during drought seasons. The non-steady flow in the aquifer groundwater is described with the Boussinesq's partial differential equations. The boundary conditions consist of the groundwater level required at the margins of the analyzed area, in conformity of the pollutant emissaries, using the double steps meth...
