PERENCANAAN TEKNIS PEMBANGUNAN CHECK DAM DESA BULUKERTO KECAMATAN BUMIAJI KOTA BATU

Bulukerto Village, located in Bumiaji District, Batu City, features hilly topography and high rainfall, making it highly susceptible to erosion and excessive surface runoff. To address these issues, a technical plan for the construction of a check dam was developed as a soil and water conservation effort. The planning process includes a survey of existing conditions, hydrological analysis to determine the design flood discharge, estimation of sediment volume, and structural design of the check dam capable of withstanding hydraulic loads and sediment accumulation. The methods employed involve rainfall intensity calculations, peak discharge analysis using the Nakayasu method, and dimensioning of the structure based on stability and sediment storage capacity. The resulting design is expected to slow down water flow, enhance infiltration, trap sediment, and improve the environmental conditions of the surrounding watershed area. Additionally, the construction of the check dam is intended to support sustainable water resource management and strengthen the region’s resilience to hydrometeorological disasters.
