Evaluation of Relief Morphometry of Kılıçözü and Acıöz Drainage Sub-Basins (Kırşehir, Turkey) in Relation to Flood Events

Abstract

Morphometric analysis of drainage basins and their channel networks plays an important role in understanding the causes of flood occurrence in basins. In the present study, morphometric analysis was carried out using Geomorphological Information System (GIS) to assess the relief morphometry of Kılıçözü and Acıöz drainage basins which are sub-basins of the Kızılırmak River, the longest river in Turkey. These basins have been subjected to flooding several times. The obtained values of slope and morphometric parameters (basin relief, relief ratio, time of concentration, hypsometric curve and hypsometric integral) indicate that the two basins do not differ from each other with respect to flood occurrence; however the Acıöz subbasin is more prone to flash floods. This result will help in producing a sustainable management plan for the basins to overcome the risk of flooding.
