PERENCANAAN ULANG CHECK DAM SUNGAI BATANG PAUHGADIH, KECAMATAN PASAMAN TIMUR, KABUPATEN PASAMAN

Abstract

sedimentary consentration, The sediments are derived from soil erosion on the upper reaches of
riversA natural phenomenon that occurs along the West coast of West Sumatra is the magnitude
of the volume of sediment moving along the coastline affected by the current wave coming from
the Indian Ocean. The river is a river of Pauhgadih Rod that has a fairly high level of insecurity
with respect to the incidence of debris flow hazard i.e. flow sediments have high levels of
concentration of sediments consisting of silt, sand, gravel and rocks. he placement of the Check
dam placed on the downstream confluence of two rivers and Weirs axis perpendicular to the flow
of the river downstream. Rainfall of 1 (one) Registrar rainfall station. From the results of the
calculation of get dimensions chekdam, width = 6 maindam mercu m, height = 10 m checkdam,
maindam kesubdam = length of 24 m, thick apron = 2 m, width sub dam = 3, 75 m, height
subdam = 6 m, with a drainhole 0, 6x0.4.
