| Abstract: |
| Flood is one of the most dangerous natural disasters that could endanger human life. There are many factors affecting the flood occurrence, the most important of which is land use. Land use can control runoff velocity, permeability and flood focusing time. One of the most important reasons for flood events is the change in land use and the increase of impenetrable levels due to the increase of residential areas and the destruction of vegetation or the conversion of forest to agricultural land. The purpose of this study is to investigate the effect of land use change on increasing the probability of occurrence of flood in Golestan province, Iran and for flood occurred in April 2019. In order to achieve this goal, remote sensing studies were done on satellite image in this area to find effective factors for this flood event. Accordingly, land use maps in the 1990 and 2018 years using Landsat satellite imagery and SVM algorithm in six different classes including: forest (F), urban area (U), agriculture (A), uncultivated land (UL), forest (F) and bare soil (BS) with a total accuracy of 85.48% and 89.86% were prepared. Then, the changes in these land uses and the impact of these changes on the flood occurred in the region were investigated. This can be the source of dangerous flood in the region in the long term. |
