Abstract

Sapon weir, which located at Kulon Progo, Yogyakarta, is a hydraulic structure that its water supply is from Progo river. Sapon weir are used to flow through ± 1850 ha rice field area, from ± 2250 ha before at 2,3 m3/sec, and to fulfill the water needs in 4 sub districts at 0,2 m3/sec. The increasing function of Sapon weir from only covering the irrigation needs, to fulfilling the water needs it is the implementation of the regulation no 8 year 2005 about water resources. The analysis of flood design using Haspers Metod, FSR Jawa-Sumatera, HSS Nakayasu, HSS Gama 1 with flood design comparation from Pasing Capacity Metod that has 1123,96 m3/sec of flood discharge in hundred year periode (Q100). The design of Sapon weir consists of main dam, complement buildings and requirement water supply pump for 1383,97 m3/sec of flood discharge hundred years period. The differences of weir design change the weir dimensions and the complement buildings.

Abstract

Progo Jumo Weir is located on Progo River, Temanggung Regency. Progo Jumo Weir only serve the irrigation area in the left side of Progo River that formerly are rainfed rice field with 1.278 Ha wide. The maksimum intake discarge is 1,942 m3/sec. FJ Mock method is used to calculate the dependable discharge of Progo river at 20% dry. Designed flood discharge calculated from HSS Gama I method is 186,041 m3/sec for 100 years return period (Q100 = 186,041 m3/sec). Rounded weir head with  4,85 m in height and +713,07 m from mean sea level is used. The weir is 39 m in effective width and the length of upstream apron floor is 8 m. . This weir use USBR Type III stilling basin with 8 m in length. The flushing gate uses four gates each 1,5 m in width. The implementation of this project  is 42 weeks and the budget plan is  Rp. 13.210.231.000,00.
