Topographical Measurements and Informatics Facilities in the Torrential Hydrographic Network Management

Abstract

In the present paper the facilities offered by different software concerning selecting the best management solution for a torrential hydrographic basin will be pointed out. The first part of the paper presents the features offered to the users of AutoCAD software in order to quantify the parameters which enable the determination of the peak discharge of a watershed. The second part of the paper is dedicated to the use of HEC-RAS software which, through the calculated value of the peak discharge of the watershed, succeeds to highlight the water level in each studied cross section, which on the basis of the adopted slope of silt deposition, enables the choice of a certain alternative of managing the torrential watershed and, moreover, to draw up the flood natural risk map for the studied area. In the final part of the paper, the possibilities offered by AutoCAD for optimizing the positioning of mainstream transversal works are exposed.
