The upstream watershed has a very important role in flowing water to the downstream area. Upstream watersheds located in highlands usually have very steep slopes with slopes of more than 15%. This causes the potential for erosion in the upstream to be large. The potential for erosion will be even greater because the steep slope causes a large amount of transport energy for water. Gravity will be greater with the slope of the slope. The purpose of this study is to classify and create a slope map of the Koto Panjang hydropower reservoir watershed. The method used in this research was data analysis with geographic information system software. The level of slope in the Kampar watershed varied greatly from flat (0-8%), gentle (8-15%), steep (15-25%), steep (25-45%), and very steep (>45%). Meanwhile, the Koto Panjang PLTA Reservoir watershed had a slightly steep slope (15-25%) covering an area of 104.465 km2, steep (25-45%) covering an area of 484.893 km2, and very steep (>45%) covering an area of 2747.813 km2. Based on the slope level in the Koto Panjang PLTA Reservoir watershed, the LS value in the watershed is 8.907.Keywords : watershed, erosion, slope

The non-uniformity topography of Sei Paku Reservoir caused non-uniform flow in the reservoir, forming unique flow pattern. This flow pattern caused the uneven of flow velocity distribution and sediment distribution in the reservoir. The uneven of flow velocity distribution and sediment distribution can affect the trend of bed configuration changes of the reservoir. It takes a form of a simulation study to determine the pattern and flow velocity distribution, and sediment distribution in the reservoir. In the simulation, topography data, flood discharge, and the water level are processed by RMA-2 that produces flow patterns and the flow velocity. Parameters such as sediment grain size and sediment concentrations are processed by SED2D that produces sediment distribution. The simulation results showed that the flow patterns affect the flow velocity distribution and the sediment distribution in the reservoir so that happen bed configuration changes of the reservoir. The bed configuration of Sei Paku reservoir classified by simulation results in “Anti Dunes” phase where upstream side suffered deposition while downstream side suffered erosion.Keyword: Simulation, flow pattern, sedimentation

(ID) Hidrologi suatu Daerah Aliran Sungai (DAS) rumit untuk diprediksi karena kekurangan data dan membutuhkan biaya yang mahal. Pada penelitian ini mengambil lokasi di sub DAS Rokan Hulu stasiun Pasir Pengaraian yang hampir setiap tahun terjadi banjir. Perencanaan dan pengolahan sumber daya air di suatu wilayah daerah aliran sungai sangat penting, maka dari itu perlunya mengetahui karakteristik suatu DAS. Perencanaan dan pengolaan sumber daya air memerlukan data debit aliran yang lengkap. Pada sub DAS ini data hujan, data debit dan data klimatologi menggunakan periode data sepuluh tahun yaitu dari tahun 2008-2017. Pemodelan hidrologi dilakukan pendekatan dengan beberapa metode, salah satunya metode soil moisture accounting di program HEC-HMS yang mana metode tersebut mensimulasikan suatu pergerakan air pada vegetasi, permukaan tanah dan di bawah permukaan tanah. Penyusunan periode kalibrasi dan verifikasi disusun dalam sembilan skema yang diharapkan mampu menghasilkan hasil yang paling optimal. Sembilan skema untuk Kalibrasi dan Verifikasi ini menggunakan metode objective function yaitu percent error in discharge volume. Skema yang paling optimal adalah skema VII (7 tahun kalibrasi 3 tahun Verifikasi), dengan nilai verifikasi 10,1%”Baik” dan Kalibrasi 0,0% “Sangat Baik”. (EN) The hydrology of a watershed is difficult to predict because of the lack of data and requires high costs. In this study taking location in the Rokan Hulu sub-watershed, Pasir Pengaraian station Almost every year flooding occurs. Planning and management of water resources in a watershed is very important and therefore it is necessary to know the characteristics of the watershed. Planning and management of water resources require complete data. in this sub-watershed rainfall data, discharge data and climatology data use a ten-year data period from 2008-2017. Hydrological modeling is approached with several methods, one of them is soil moisture accounting method in the HEC-HMS program where the method simulates a movement of water on vegetation, soil surface and below ground level. The preparation of the calibration and verification periods arranged in nine schemes is expected to produce the most optimal results. The nine schemes for Calibration and Verification use the objective function method, which is the percentage error in discharge volume. The most optimal scheme is the scheme VII (7 years calibration 3 years Verification), with a verification value of 10.1% "Good" and Calibration 0.0% "Very Good".

Salah satu permasalahan yang sering terjadi pada loncat air melalui pintu sorong tegak (sluice gate) adalah penentuan letak awal loncat air. Penelitian ini membahas cara untuk menyelesaikan permasalahan tersebut. Penelitian karakteristik loncat air melalui pintu sorong tegak dilakukan dengan menggunakan model pintu sorong tegak yang diletakkan pada model saluran terbuka (flume) dengan lebar saluran 0,078 m. Debit aliran yang disimulasikan ada 5 variasi, yaitu : 0,001633 m3/det, 0,001705 m3/det, 0,001783 m3/det, 0,00185 m3/det dan 0,001955 m3/det, dengan 5 variasi bukaan pintu untuk masing-masing debit: 0,028 m, 0,025 m, 0,023 m, 0,020 m dan 0,018 m. Data hasil penelitian dianalisis dengan analisis dimensi metode Buckingham sehingga diperoleh hasil dalam bentuk bilangan tak berdimensi dan digambarkan dalam bentuk grafik hubungan antar parameter. Hasil penelitian dan analisis grafik menunjukkan bahwa hubungan antar parameter terhadap letak awal loncat air tidak linier. Letak awal loncat air dipengaruhi oleh muka air hilir (y3/a) dan tipe loncat air dan debit (a5.g/Q2) yang ditunjukkan dengan hubungan logaritma dan eksponensial. Dari hasil verifikasi antara hasil grafik dengan hasil penelitian di laboratorium diperoleh tingkat kesalahan lebih kecil dari 10 %.

Suatu model telah dikembangkan untuk mensimulasi curah hujan harian pada 4 stasiun pengukur hujan yang berlokasi di DAS Kampar. Curah hujan yang merupakan sesuatu yang tidak pasti dan salah satu faktor penting dalam sebuah perencanaan akan disimulasi dengan sebuah model yaitu stokastik rantai Markov. Dengan menggunakan variabel acak, model stokastik rantai Markov dilakukan untuk mensimulasi deretan hari hujan dan kering dan untuk mensimulasi serangkaian besar curah hujan harian dengan menggunakan distribusi gamma. Analisa persentase perbedaan jumlah hari hujan dan total curah hujan dilakukan untuk mengetahui tingkat perbedaan antara simulasi dan pengamatan. Dan analisa uji Chi-Kuadrat dilakukan menjadi 2 bentuk uji apakah memiliki populasi yang sama yaitu untuk data simulasi dan pengamatan dan untuk data simulasi dan distribusi gamma. Hasil pengujian yang dilakukan terhadap 120 data tiap-tiap stasiun menyatakan bahwa berdasarkan uji Chi-kuadrat, tidak lebih dari 50% data curah hujan hasil simulasi sesuai atau cocok dengan curah hujan hasil pengamatan, dan bahwa kurang dari 30% data curah hujan hasil simulasi sesuai atau cocok dengan distribusi gamma. Tingkat kehandalan rantai Markov dalam mensimulasi data curah hujan di DAS Kampar adalah rendah karena nilai koefisien korelasi (r) antara model dan pengamatan lebih kecil dari nilai koefisien korelasi kritik (rkritik).Kata Kunci : curah hujan harian, hari hujan, model rantai Markov, data hujan simulasi.ABSTRACT
