The impact of drainage on terrain UGV movement

The drainage (hydrosphere) is one of the main elements determining the military vehicles mobility. The grade of this determination is given by width, gradient, depth and qualitative parameters of drainage on overall forms of its occurrence. The goal of this paper is the identification of main geographical factors and parameters of drainage that affect the modelling of cross-country movement. In paper are included some classifications of overall coverages of terrain by a drainage, drainage structure, characteristics of watercourse banks, watercourse width, depth of watercourses and water expenses, character of a bottom, water flow rate and flow speed, climatic effects and mutual position of drainage and other geographical subjects.
