Yağışların tarım alanlarında sebep olduğu göllenmelerin Sentinel-1 uydu görüntüleri ile analizi

Abstract

In this study, the rainfall that was effective between 24.12.2019 - 08.01.2020 in Adana was analyzed together with the daily total precipitation data from 18 Automatic Meteorological Observation Stations located within and around the study area. The study area consists of the central districts of Adana province; Seyhan, Çukurova, Sarıçam and Yüreğir and the district of Karataş. The pondings in the districts mentioned due to these precipitations were analyzed using Sentinel-1 satellite images. Three different images were used as a satellite image in the study; before the precipitation (09.12.2019), during the precipitation (02.01.2020) and at the end of the precipitation (08.01.2020). In addition, the change of soil moisture in the region with precipitation was also examined. Soil Moisture Active Passive (SMAP) was used as a soil moisture data source. In the study; the effects of altitude, slope, soil structure, soil moisture and precipitation on pondings were investigated. Precipitation increased soil moisture up to 2 times, and therefore it is thought that it helped pondings due to the decrease of leakage capacity of the soil. According to the analyses, in regions where ponding is intense; it has been mostly determined that the hydrological soil group is “D” and the slope is below 1%.
