Abstract

Irrigation drainage evaluation in the encroached villages aims to find solutions to overcome flood in the agricultural drainage channels, Perambahan Banyuasin Regency so that the distribution of outflow is balanced and there is no flood. This evaluation uses primary data obtained directly from the field and secondary data in the form of climatological rainfall data originating from BMKG Palembang City, and topographic data obtained directly from the field. This research was conducted by the following stages: (1) Maximum Daily Rainfall Calculations (2) Frequency Analysis (3) Planned Rain (4) Flood Discharge (5) Channel Dimensions Calculation( 6) Hec-Ras Analysis. The results of the study based on the suitability test concluded that the distribution to be used for the planned rainfall was the log normal distribution. Because it has the smallest Δmaks value of 0.07 of all distributions for SCS Plan Debit Calculation, the maximum value is 4,395 m3/s, with trapezoidal shape. The dimensions of the planned drainage are b = 3 m, H = 2.02 m, guard height of 0.6 m, and channel slope of 0.0002070 while for Hec-Ras Analysis the overflow height before normalization is 5.9 m, and after normalization the overflow is reduced by 2.8.
