Description:
Air merupakan karunia Tuhan Yang Maha Esa yang
diperlukan oleh manusia, hewan, dan tumbuh – tumbuhan. Apalagi air yang ada di sungai sangat besar manfaatnya untuk keperluan air irigasi persawahan, maka dari itu perlu adanya suatu bangunan untuk penangkap air tersebut berupa bendung. Bendung Blimbing terletak di Desa Prayungan Kecamatan Sawoo Kabupaten Ponorogo. Bendung ini mengairi sawah seluas 139 Ha. Bendung Blimbing mengambil air dari kali Sawoo yang masuk daerah Irigasi Keyang atas. Bendung ini di kelola oleh Dinas Pekerjaan Umum Kabupaten Ponorogo Bidang Sumber Daya Air. Dengan dibangunnya bendung Blimbing diharapkan mampu mengairi areal sawah tersebut. Analisa hidrologi untuk menentukan debit banjir pada periode ulang 100 tahun, menentukan hujan rata – rata dengan menggunakan metode Theisen Polygon. Perhitungan tinggi hujan rencana dengan menggunakan metode Log-Persson tipe III dan distribusi Normal. Uji kecocokan distribusi frekwensi dengan menggunakan metode Uji Chi-Kuadrat dan Uji Smirnov- Kolmogorov. Perhitungan banjir rencana dengan menggunakan metode Nakayasu. Lebar total bendung (B) sesuai dengan bangunan lama yaitu 38 meter. Elevasi mercu bendung +151,22, dihitung berdasarkan elevasi Intake bangunan lama, yaitu elevasi +150.80 lebar pintu 0,80 m tinggi bukaan pintu 0,28 m elevasi muka air down stream +150.93. Mercu bendung direncanakan tipe bulat, kolam olak direncanakan tipe bak tenggelam. Tubuh bendung direncanakan stabil terhadap geser, guling, erosi bawah tanah (piping), dan bangunan tidak turun.
Alt. Description
Water is a gift of God Almighty which is required by humans, animals, and grow - plants. Moreover, the water in the river is very beneficial for rice irrigation water, therefore there is need for a building to catch water in the form of the weir. Blimbing weir is located in the Village District Prayungan Sawoo Ponorogo. This weir to irrigate rice fields covering an area of 139 Ha. Weir Blimbing time fetching water from entering the area Sawoo Irrigation Keyang above. This dam is managed by the Public Works Department Ponorogo Water Resources Sector. With the construction of weirs Blimbing expected to irrigate the rice acreage. Hydrological analysis to determine the flood discharge at the 100-year return period, determine the average rainfall - average using Polygon Theisen. Calculation of the high rain plan using the log-Persson type III and Normal distribution. Test fit the frequency distribution using the Chi-Square and Kolmogorov-Smirnov Test. Calculation of flood plan by using the method Nakayasu. Total width of the weir (B) in accordance with the old building is 38 meters. Summit elevation +151.22 weir, intake was calculated based on the elevation of the old building, the elevation +150.80 0.80 m wide door 0.28 m high door openings down stream water level elevation of +150.93. Crow\\\\\\\'s planned weir type round, the pool is planned megrim tub type sink. Planned dam body is stable against sliding, rolling, underground erosion (piping), and the building does not go down.
