Abstract
Waduk Wonorejo mulai beroperasi sejak tahun 2011,
terletak di desa Wonorejo, kecamatan Pagerwojo, sekitar 12
kilometer ke barat dari kota Tulungagung. Waduk Wonorejo
seluas 30,08km2 diharapkan dapat beroperasi dan melayani
kebutuhan air hingga waktu yang telah direncanakan. Selain
sebagai fungsi pengembangan sumber daya air juga di
gunakan untuk pembangkit listrik tenaga air, irigasi,
pariwisata, olah raga dan lain lain.
Masalah utama yang dihadapi dalam pembangunan
dan pengoperasian waduk adalah banyaknya sedimentasi pada
sungai sebagai aliran utama yang masuk ke waduk sehingga
membuat air yang akan di distribusikan menjadi kotor dan
juga melonjak nya elevasi muka air pada Waduk Wonorejo.
Oleh karena itu perlu direncanakan bangunan pengendali
sedimen kali Gondang di Hulu Waduk.
Dari hasil analisa bangunan pengendali sedimen yang
ditunjang dengan data data primer dan sekunder diperoleh
besarnya Debris yang mengalir sebesar 80,58 m3/det, Tinggi
Bangunan Main Dam setinggi 12,5m dengan kemiringan Hulu
sebesar 1:0,75 dan kemiringan Hilir sebesar 1:0,2, Lebar
pondasi Main Dam 13,375m dengan kemiringan sungai rata
rata 0,0123 bisa menampung sedimen sebesar 209412,345 m3.
Dengan demikian sedimen yang akan masuk ke
Waduk Wonorejo akan bisa ditanggulangi.
==========================================================================================================
Reservoir Wonorejo began operation since 2011, is
located in the village
of Wonorejo, Pagerwojo subdistrict, about 12 kilometers to
the west of the city vBulletin. Reservoir area of
30.08 km2 Wonorejo expected to operate and serve the needs
of the water until the planned time. In addition as a function
of the development of water resources are also
used for hydroelectric power generation, irrigation, tourism,
sports and others.
The main problems encountered in
the development and operation of its dams are a lot of
sediment in the river as the main flow stream that goes to the
reservoir so that the
water will make distributed and also jumped into his dirty wat
er level in the
reservoir Wonorejo. Therefore in building sediment
control plan in Gondang river..
The results from the processing of the obtained data
flow calculation for 80.58 m / s, the calculation of the volume
of sediment entering 209,412.345 m3, structure calculations
obtained m B1 = 15, B2 = 18.8 m, Bmin = 1,5 m, Upstream
slope of (m) = 1: 0,75, Slope Downstream (n) = 1: 0,2,
Scouring Depth (T) = 0,89 m, and also the calculation of the
stability of sediment control structures. Sediment control
structures so that planning can be built and also functioned
optimally.
