GIS METHODOLOGY FOR THE CALCULATION OF PROBABLE PEAK DISCHARGE TIME OF CONCENTRATION IN SMALL DRAINAGE BASINS. CASE STUDY. Authors: ŞT. BILAŞCO. |

Abstract: The model proposes a methodology for the calculation of the time of concentration using geoinformation software. Water run-off on slopes depends both on their configuration and on the collected water volume and in this way the slope flow characteristics differ very much from one drainage basin to another. At the same time, the period during which the flood flows on the drainage basin’s area is extremely important in the warning and evacuation process in order to avoid eventual disasters. While the estimation of the time of concentration on the base of empiric equations is time-consuming, the proposed model integrates the numerical and spatial databases specific to the hydrologic models into a spatial analysis formula with the help of ArcGis software extensions, in this way the computation and spatialization of the time of concentration becoming time-efficient. Keywords: methodology, G.I.S., time of concentration, database. |
