Abstract
Mathematical models of water flow (flows of fast and e-fast water), which can be used for describing the overland flow, are proposed. Properties of these models are studied, and the equation for the motion of the water-ground interface is derived. A model is proposed for the joint motion of ground with water, which is applied to revealing the qualitative picture of soil erosion caused by the overland flow. Examples and results of numerical modeling of the process of overland flow and development of erosion are presented. This study is the basis for the technology of estimating the erosion danger in the GeoTime network geoinformation system, http://www.geo.iitp.ru/geotime/ (Section “Ruza”).
