Abstract
The work has interdisciplinary character. The geodesy-cartography-photogrammetry product (DTM) and the photogrammetry product (digital orthophoto) were used to determination of river valley hydraulic characteristic. DTM was used to direct description of geometry of water flow region on the two-dimensional hydrodynamic model RMA2 from the SMS software package – the mesh nodes of hydrodynamic model were imported from DTM. Also it was found that digital orthophoto was useful to determination of material types areas, with which roughness values were combined.
