On Accounting for Evaporation or Infiltration Free Surface in Some Problems of Filtration Theory

Bereslavskii Eduard Naumovich
2019 World Journal of Agriculture and Soil Science  
The following filtration flows with unknown free boundaries are investigated: • in case of a flow past the Zhukovsky groove in the case when the soil layer is underlain along its entire length with an impermeable base and evaporation from the free surface occurs; • in case of a flow past the Zhukovsky groove in the case when the underlying layer is a completely well-permeable aquifer and infiltration occurs on the free surface; • when groundwater moves in a rectangular bridge with a partially
more » ... penetrable vertical wall in the presence of evaporation from the free surface; • when groundwater moves to an imperfect gallery in the presence of evaporation from the free surface.
