      Abstract
      Waduk Nadra Krenceng dibuat untuk menampung air Sungai Kapudenok dan sungai Brambang. Seiring jalanya waktu, penggunaan lahan yang menyebabkan perubahan tutupan lahan yang menyebabkan erosi pada DAS Krenceng dan pembuangan limbah industri menyebabkan adanya penurunan kualitas air waduk Nadra Krenceng Waduk Nadra Krenceng mengalami laju erosi mencapai 36.946 ton/tahun atau setara 984 m3/tahun yang membuat terjadinya pencemaran air yang dilihat dari parameter warna, Padatan tersuspensi total (TSS), Padatan terlarut total (TDS), dan Warna. Sabo Dam dibangun untuk mengurangi sedimen yang masuk. Rancangan Sabo dam sebagai pengendali sedimen didapat sedimen yang dapat ditampung dalam sabo dam sebesar 41378.66 m3 dengan debit banjir debit rencana 50 tahun 95.91 m3/det). panjang lantai apron (L) sebesar 22 m. Tinggi efektif dari sabo dam didapat 8 m dan besar
       
      The Nadra Krenceng Reservoir was made to accommodate the water of the Kapudenok and Brambang rivers. Over time, land use causes changes in land cover which causes erosion in the Krenceng watershed and industrial waste disposal causes a decrease in the water quality of the Nadra Krenceng reservoir. water as seen from the color parameters, total suspended solids (TSS), total dissolved solids (TDS), and color. Sabo Dam was built to reduce incoming sediment. The design of the sabo dam as a sediment controller obtained sediment that can be accommodated in the sabo dam of 41378.66 m3 with a planned 50 year flood discharge discharge of 95.91 m3/s). apron floor length (L) of 22 m. The effective height of the sabo dam is 8 m and the width of the base of the spillway is 39.17 m, the width of the top of the spillway is 40.57 m..
