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.
