Wilayah DAS Serayu Hulu merupakan DAS prioritas yang memerlukan langkah pengelolaan yang komprehensif. Aplikasi model Soil and Water Assessment Tool (SWAT) dapat digunakan sebagai media untuk  perencanaan konservasi ataupun evaluasi respon DAS (debit aliran permukaan, sedimen dan pencemaran sungai). Tujuan utama dari penelitian ini adalah menjalankan model SWAT di DAS Serayu Hulu untuk mengetahui laju sedimen di wilayah ini. Pemodelan SWAT membutuhkan sejumlah input parameter berupa relief, tanah, tutupan lahan dan pengelolaan lahan. Pedogeomorfologi digunakan sebagai batas satuan tanah karena tidak tersedianya peta tanah di wilayah penelitian. Hasil Penerapan model SWAT di DAS Serayu Hulu menghasilkan nilai yang cukup memuaskan, hal ini ditunjukkan nilai R2 mencapai 0,94. Hasil pemodelan SWAT dengan menggunakan data selama 10 tahun (2004-2013) menunjukkan bahwa DAS Serayu Hulu memiliki rerata hasil sedimen sebesar 1.926.900 ton/tahun. Sub DAS 8,9 11, 17, 18, dan 19 merupakan penghasil sedimen tertinggi di DAS Serayu Hulu dengan hasil sedimen 43.931– 121.434 ton/ha/tahun.

Abstract Erosion and sedimentation are problems that often occur in watershed ecosystems. The SWAT model (Soil and Water Assessment Tool) can be used to determine the output of a watershed’s performance. Jenelata sub-watershed area is one of the largest sub-watersheds of the Jeneberang watershed with 22.800 ha. This study aims to determine the spatial distribution of the hydrologic response unit (HRU) and analyze the rate of erosion and sedimentation in the Jenelata sub-watershed. The results showed that most HRUs are in secondary dryland forests with 447 HRU (19.09%). The level of erosion in the very light category, namely 5.74 ton/ha/year (37.53%) and light 34.71 ton/ha/year (27.76%), was in the villages of Moncongloe, Tana Karaeng, Sicini, Paladindang, Towata, Parang Lampoa, Manuju, and Buakkang. Meanwhile, moderate erosion was 104.07 ton/ha/year (23.92%), high 289.65 ton/ha/year (9.59%), and very high 553.74 ton/ha/year (1.20%) located in the villages of Pattallikang, Mangempang, Bontomanai, Bissoloro, Rannaloe, Jenebatu, and Sapaya. The largest sedimentation is 133.18 ton/ha/year in sub-watershed17, located in Bissoloro and Rannaloe villages.

Batang Arau is one of the rivers that flows in the city of Padang, the upstream part of the Batang Arau watershed starting from the Lubuk Paraku river which is in the northeast of Padang City, with a water catchment area of 2,504 hectares which is Dr. Muhammad Hatta, Nature Reserve Area Barisan I and Arau downstream. The Batang Arau watershed has decreased its primary forest area due to the large number of additional settlements. The increase in residential area resulted in the land that was previously not waterproof. The mainstay discharge always increases in the rainy season and decreases in the dry season. The mainstay discharge in the Batang Arau watershed is calculated using the Fj Mock method. The Batang Arau watershed also knows the mainstay discharge that occurred in 2010, 2012 and 2018 using the Soil and Water Assessment Tool (SWAT) model. The analysis was obtained from four processes, namely delineation of the watershed, the formation of the Hydrologic Response Unit (HRU), the formation of climatological data, and the simulation process. For the HRU analysis of the Batang Arau watershed, it was obtained 7 sub-watersheds, the dominant HRU, namely primary dryland forest, was 74.68%.

Batang Kuranji is one of six rivers that flow in the city of Padang, and is the main source of water for residents of Padang City to meet the raw water which is then processed into clean water and the needs of Mt. Nago irrigation water. The increase in population causes the population to move to a higher area (green zone). Batang Kuranji watershed has experienced a reduction in the area of forest land due to changes in land use activities by the population movement. As a result, land that was not watertight at first became watertight, the mainstay discharge or expected discharge is always available, always increasing during the rainy season and decreasing during the dry season. This study was conducted to determine the extent of land use change in the Batang Kuranji watershed, also to determine the main discharge that occurred in 2009, 2011, and 2017 using the Soil and Water Assessment Tool (SWAT) model. The analysis consists of four processes, namely watershed delineation, formation of a Hydrologic Response Unit (HRU), formation of climatological data, and finally the simulation process. HRU analysis results obtained by Batang Kuranji watershed into 9 sub-watersheds, the dominant HRU is protection forest by 62%, soil type with depth (solum) level A and B, runoff coefficient of 0.3 and NS value obtained by 0.6. This shows that the SWAT model can predict the hydrological process in the upstream Batang Kuranji watershed. The most influential land use on surface runoff is land use for settlement.

Abstract The purpose of this study is to investigate the future runoff into the Nong Han Lake under the effects of climate change. The hydrological model Soil and Water Assessment Tool (SWAT) has been selected for this study. The calibration and validation were performed by comparing the simulated and observed runoff from gauging station KH90 for the period 2001–2003 and 2004–2005, respectively. Future climate projections were generated by Providing Regional Climates for Impacts Studies (PRECIS) under the A2 and B2 scenarios. The SWAT model yielded good results in comparison to the baseline; moreover, the results of the PRECIS model showed that both precipitations and temperatures increased. Consequently, the amount of runoff calculated by SWAT under the A2 and B2 scenarios was higher than that for the baseline. In addition, the amount of runoff calculated considering the A2 scenario was higher than that considering the B2 scenario, due to higher average annual precipitations in the former case. The methodology and results of this study constitute key information for stakeholders, especially for the development of effective water management systems in the lake, such as designing a rule curve to cope with any future incidents.
