Abstract

Water is a very basic need for All living things on this earth without exception. The Kripik River is currently not being utilized by community optimally. For this reason, it is necessary to increase Irrigation Area which aims to increase agricultural production. Currently, the Bendung Kripik area serves an irrigation area of 95,94 Ha with the height of the exsisting weir lighthouse is 1 m.The improvement of the irrigation network is carried out based on secondary data with other supporting data. The analysis carried out includes: hydrological analysis which includes : watershed, maximum rainfall, flood discharge, average rainfall, average climatology, Eto – Penman, F.J Mock mainstay discharge, planting patterns then carried out channel design, weir design and calculation of weir stability.In this study, it was proposed to increase the rice field area by 130.17 Ha From the results of hydrological analysis, the flood discharge value of the Nakayasu Synthetic Unit Hydrograph (HSS) method was obtained when repeating 100 th by 40.10 m3 / s. The water requirement for irrigation of D.I Kripik after the addition of the area is 0.086 m3 / s. As for the bed, a weir width of 30 m with a weir height of 1.05 m is required, a weir lighthouse width of 28 m, a rinse width of 1 m and a pillar width of 1 m (2 Pillars of 1 m each). The radius of the spherical threshold type weir is 0.5 m, the olak pond type is USBR Type IV with a length of 3.50m. Keywords: Irrigation, Weir, Flood Discharge

Abstract

Design flood is one of the important aspects in the design of water structures. Calculation of the design flood is very dependent on the existing rain data in the watershed area. The amount of flood discharge is not only influenced by the value of rainfall but also depends on the duration and distribution of rainfall per unit of time.This study was conducted to determine duration of rainfall that produces the maximum flood discharge for Tenggang and Sringin River. Calculation of flood discharge for Tenggang and Sringin River was carried out using a rainfall distribution pattern (hyetograph) for rainfall durations of 2 hours, 3 hours, 4 hours and 5 hours with the distribution of rainfall distribution referring to hourly rain data at Maritime Station. Results of analysis show that different distributions are produce different flood discharge values. For Tenggang and Sringin rivers, the maximum flood discharge value is obtained at a rain duration of 2 hours.Keywords: flood discharge, rainfall duration, hyetograph
