| 概要 |
This study investigates the hydrological dynamics and rainfall patterns in the Kampar River Basin from 2018 to 2023 using Synthetic Aperture Radar (SAR) data from Sentinel-1. The analysis reveals sign...ificant year-to-year variations in annual rainfall, with 2019 exhibiting notably low intensity, aligning with classifications from the Indonesian Meteorological, Climatological, and Geophysical Agency (BMKG). The months from September to December consistently experience higher rainfall, contributing to increased water volumes and flood risks in the river basin. Using ArcMap 10.3 software, the flood extent was mapped based on Sentinel-1 imagery, identifying recurring flood-prone areas in Pekanbaru and Kampar, particularly during peak rainfall periods. This spatial analysis, combined with rainfall data, offers a comprehensive view of flood dynamics in the region. The study also incorporates interferometric SAR analysis to explore land surface deformations, revealing patterns of land subsidence despite challenges such as atmospheric conditions and vegetation interference. These findings underscore the need for integrated approaches that consider climatic, hydrological, and geophysical factors to enhance flood risk mitigation strategies. The study demonstrates the utility of SAR data in detecting and analyzing hydrological patterns, contributing to the understanding of environmental changes in the Kampar River Basin and offering valuable insights for future research and practical applications in the field of hydrology.続きを見る
