Consideration is given to the model of motion of sweet 
groundwater in a trapezoidal pressure water-bearing stratum to a sea 
with saline water. For studying this model, a mixed multiparametric 
boundary-value problem of the theory of analytical functions is formulated 
and solved using the P. Ya. Polubarinova-Kochina method. The algorithm 
of calculation of the intrusion of seawater into the sweet-water layer 
in the case where its right-hand boundary modeling the littoral zone 
of the sea floor makes an arbitrary angle with the horizon is developed 
based on this scheme. The characteristic features of the modeled process 
and the influence of all determining physical parameters on the character 
and degree of intrusion are analyzed using the exact analytical dependences 
obtained and numerical calculations.
