| dc.description.abstract | Rokan Hulu and Rokan Hilir Regencies are included in the Rokan and Kubu Watersheds. In the Rokan Hulu district there are several rivers, two of which are fairly large rivers, the Rokan Kanan River and the Rokan Kiri River. Rokan Hilir Regency is also passed by the Rokan Kanan River, which is a place of union with the Rokan Kiri River. Next to these large rivers there are many tributaries that all flow into the big river. At the edge and along the river, including tributaries, is often a flood subscription during the rainy season. The purpose of this study was to identify floodprone areas, in Rokan Hulu and Rokan Hilir Regencies so as to produce maps of flood-prone areas in Rokan Hulu and Rokan Hilir Regencies. To map flood-prone areas in Rokan Hulu and Rokan Hilir Regencies, it can be done with the help of remote sensing data based on Geographic Information Systems (GIS). From the analysis based on overlay maps of soil types, slope classes, land cover and rainfall with the scores and weightings given for each parameter that influence each other to identify the level of flood vulnerability in the study area, in the safe category 14,709.48 ha or 0.9%, Non-hazardous category 921,554.03 ha or 56.33%, the dangerous category is 496,025.36 ha or 30.32% and the category is very vulnerable for flood disaster 203,790.36 ha or 12.46% respectively from the study area | en_US |
