Different approaches to two-dimensional numerical modelling of natural watercourses

Different approaches to two-dimensional numerical modelling of natural watercourses

Results obtained by analysis of three different approaches to numerical modelling of open watercourses are presented in the paper. Two examples of flow, uniform flow on the physical model of a curve at the Tisza River and nonuniform flow at the Danube River, are analysed. Standard error analysis has...
