The effects of catchment melioration on land use types and land cover (LULC) between 1990 - 2014 in Çorum - Osmancık - Emine Creek watersheds

Abstract

Emine creek watershed (12 127.1 ha) have been the subject of watershed melioration studies since 1990. Pasture rehabilitation, soil conservation and afforestation works were carried out within these applications. In this study, the achievement of watershed melioration studies carried out between the years 1990 - 2014 and changes in the land use type/land cover (LUT/LC) in the watershed were assessed. Field measurements, remote sensing (RS) and Geographic Information Systems (GIS) techniques were used for determining LUT/LC changes. It has determined that since the beginning of watershed melioration works, the productive forest areas have increased by 22.5 %, degraded forests by 9 %, settlements areas by 4.4 %. On the other hand, opening areas have decreased by 31.8 % and cultivated areas by 3.4 %. According to the results of this study, forest areas were determined to increase by 40 %.
