PERENCANAAN BENDUNG TETAP BATANG LUMPO I KECAMATAN IV JURAI KABUPATEN PESISIR SELATAN

Abstract

Weir is transverse building river serves to elevate water to be taken down and streamed to a channel through the building retrieval. The planning weir river Batang Lumpo I is planned by using mercu type Ogee. Structure weir planned in Kecamatan IV JUrai. In making this Final Task performed the calculations such as hydrological analysis, calculation hidrolis weir, calculation dimensions weir and calculation stability weir. Supporting data is topographic maps 1:50.000 scale and rainfall data based on 15 years of observations. Weir is planned for the age of the planned 100 years. From the calculation results obtained : catchment area of 71 km2, discharge 100 annual (Q100) = 361,3360 m3/dt and high energy (H1) = 2,875 m, so can irrigate agricultural areas covering an area of 404 Ha.
