Penentuan Nilai Efesiensi Distribusi Air pada Saluran Irigasi Sungai Wampu Kecamatan Stabat Kabupaten Langkat

Abstract

Water distribution efficiency in irrigation channels refers to how well the channels deliver water to the plants and is expressed as a percentage. The objective of this study is to calculate the efficiency level of irrigation water usage in secondary, primary, and tertiary irrigation channels in the Sei Wampu irrigation area, Langkat Regency.. From the research conducted, the total channel distribution efficiency was found to be 68.3%, with a water loss percentage of 31.7%. The seepage rate was 0.0681 mm/day, the evaporation rate was 3.621 mm/day, and the percolation rate was 5 mm/day.
