Abstract

Infiltration is a very important component because the problem of soil conservation is the regulation of the relationship between rainfall intensity and infiltration capacity, as well as the regulation of surface runoff. Surface runoff can only be regulated by increasing the ability of the soil to store water, mainly by improving or increasing infiltration capacity. Infiltration capacity is the maximum rate of water that can enter the soil at one time. Infiltration is one of the phases of the hydrological cycle, it is important to know because it will affect runoff, flooding, erosion, availability of water for plants, groundwater, and availability of river flow in the dry season. So this study analyzed how infiltration affects the slope and compared using Horton's formula. In this study, data collection methods were carried out in the laboratory and then processed using the Horton method and the results were compared. From the research, it was found that a large infiltration rate with a small slope besides that, with direct observation the infiltration rate is greater than the Horton method.

Abstract

Sungai Jeneberang merupakan salah satu sungai yang ada di Sulawesi Selatan, dan memiliki panjang 78,75 km. Sungai Jeneberang memiliki Daerah Aliran Sungai (DAS) sekitar 782,85 km². Tujuan penelitian ini untuk mengetahui debit maksimum yang melewati Sungai Jeneberang dan mengetahui hasil analisis karakteristik aliran pada sungai dengan menggunakan HEC-RAS 6.0. Dalam penelitian ini menggunakan metode kuantitatif, dengan melakukan pengumpulan data sekunder seperti peta DAS, data curah hujan, data cross section, dan long section. Hasil penelitian ini menghasilkan nilai debit maksimum yang diperoleh dari nilai metode HSS nakayasu, karena memiliki nilai yang lebih tinggi bila dibandingkan dengan metode yang lain artinya nilai debit ini dapat mencakup nilai debit yang lebih kecil. Nilai debit maksimum berturut-turut yaitu : 486,811; 577,485; 631,897; 683,278; 694,044; 737,010; 777,541 dan 816.585 m3/detik. Analisis karakteristik aliran dengan menggunakan software HEC-RAS 6.0 pada aliran Sungai Jeneberang diperoleh suatu hasil analisis karakteristik aliran dimana STA 0 adalah aliran kritis, sedangkan STA 1 s/d 62 merupakan aliran subkritis (Fr 1,0).
