Description
Summary:Tugu Dam is a Dam whose located on Kali Keser, Nglinggis Village, Trenggalek Regency, East Java Province, Indonesia. The Water comes from Keser Catchment Area of 43.07 km2 which will be dammed for flood control and released for needs suck as irrigation, drinking water, electricity, etc. Dam storage was designed to dam 17.661.305 m3 at +269 m elevation with dead storage of 1.668.810 m3 at +216.34 m elevation which will makes lifespan of dam about 47-68 years. Precipitation Design is analysed using Gumbel distribution and PMP is analysed using Hershfield Method with the result was 577.43 mm and Design Flood is calculated using HSS ITB 2-b Hydrograph with the result PMF 1404.16 m3/s. Spillway is designed to be Ogee Type with 22 m width and 10 m height Radial Gate which will makes peak discharge rate of about 1192.5 m3/s Dam is designed to be embankment with central core, 98 m height (+278 m elevation) from river bed (+180 m elevation), 12 m peak width, upstream slope of 1:2.5, and downstream slope of 1:2
