ABSTRACT
Unidimensional or linear planoparallel filtration of groundwater is a partial case of the more general planar, planovertical and spatial kinds of flows occurring in nature and appearing in the zone of action of the aforementioned engineering practices. The filtration of water in natural groundwater flows and the sphere of interaction on these currents of water reservoirs, canals, drainages etc., are likewise studied in cross-section as linear unidimensional processes. The construction of depression curves consists of determining the values of thickness of the groundwater flow h and elevations of the piezometric levels H at those points of the water layer for which experimental data is not available. In the case of non-uniform infiltration recharge the computed function is easily obtained by the method of fragments. Vertical unidimensional filtration of groundwater appears under canals, rivers and gullies when the water table occurs at depth.
