INFLUENCE OF THE INCLINATIONOF THE SEA FLOOR (SLOPE)
ON INTRUSION IN LITTORAL ZONES

Consideration is given to the two-dimensional (in the vertical plane)
steady-state flow of fresh groundwater in a semiinfinite pressure
water-bearing layer to a saltwater sea the littoral part of the zone
of whose floor makes an arbitrary angle with the horizon. An algorithm
of calculation of the intrusion (i.e., penetration) of seawater into
the littoral freshwater strata has been developed based on this model.
A hydrodynamic analysis of the structure and characteristic features
of the process modeled is given using the exact analytical dependences
obtained with the P. Ya. Polubarinova-Kochina method; the influence
of each determining physical parameter of the model and of the angle
of inclination of the littoral part of the sea-floor zone on the degree 
of intrusion has been evaluated.
