Hydraulic Analysis of Linear Dewatering Systems

Abstract
This paper is devoted to the problem of determination of steady-state, fully saturated flow velocities and water discharge near drains, ditches, series of wells, and similar hydrogeological objects. Traditional computational methods, based on one- (1D) and two-dimensional (2D) models, give satisfying results only in simple cases, for aquifers of regular shapes and uniform properties, but fail in more complex situations. The present paper proposes a quasi-spatial model of filtration velocity. The model is composed of two elements: first, the equation of depth-averaged 2D flow (which determines the shape of the water table, in free-surface filtration, or piezometric pressure in artesian filtration), and second, the equation of vertical 2D flow in characteristic computational profiles. The capability of the model is illustrated by considering a technical example (an existing hydrogeological barrier near Janikowo in Poland).
