Evaluation of flood risk analyses with AHP, Kriging, and weighted sum models: example of Çapakçur, Yeşilköy, and Yamaç microcatchments.

The present study aims to use the Bingol city center and agricultural plain as a base in future flood management plans and scenarios through flood modeling. In accordance with this purpose, the precipitation map of the catchment was prepared using the Kriging method by assigning values, with the Schreiber formula. Then, the slope, aspect, distance to the stream, land use, geology, soil, and precipitation maps were classified according to the analytical hierarchy process, and consistency indices and consistency ratios were calculated; thus, the factors affecting the flood were ranked as precipitation (CI 0.324), distance to the stream (CI 0.207), slope (CI 0.168), geology (CI 0.101), soil (CI 0.091), land use (CI 0.087), and aspect (CI 0.022). In the last step, consistency indices calculated by the AHP method were superposed on the weighted sum method, and then flood risk analysis was performed.
