Pemodelan Luas Genangan Banjir Batang Lunto di Wilayah Kota Sawahlunto

Flood modeling of the Batang Lunto River, a UNESCO-listed cultural heritage site in Sawahlunto, West Sumatra, reveals significant flood risk across 125.70 hectares. Using hydrological and hydrodynamic simulations with HEC-Ras 6.3.1 and ArcGIS 10.3, researchers mapped inundation areas for return periods of 2 to 100 years, showing that flood-prone zones could expand from 14.42% (18.12 Ha) at a 2-year return period to over half the area (50.68%, 63.70 Ha) at a 100-year interval. This study provides critical data for disaster mitigation in a region where flooding threatens heritage assets and geopark tourism destinations, offering actionable insights for urban planning and risk management.
