“…Three morphometric aspects like linear, areal and relief have been studied for prioritization of micro-watershed, and they are contributed for the demarcation of erosion susceptible risk assessment (Biswas et al 1999;Sujatha et al 2014;Malik and Bhat 2014). Linear and relief parameters have a positive relationship with the erosion susceptibility, whereas aerial parameters have an inverse relationship with erodibility (Nooka et al 2005;Chauhan et al 2016).…”

“…Morphometric parameters help in estimating the rank priority that predicts the deficit and surplus zones of soil erosion in every sub-basin (Deepika et al 2013). Land use and land cover (LULC) change is another important integrating parameter for the estimation of basin prioritization and land degradation or deterioration of watershed status under GIS platform (Malik and Bhat 2014;Sujatha et al 2014;Altaf et al 2014). Ground slope and gradient of the drainage network provide the structural arrangement of three morphometric aspects, i.e.…”

Environmental processes are interrupted by the water action like soil erosion, mass movement as well as siltation on the dam in the undulating catchment area. Soil erosion is one of them and degraded the basin potentiality. This paper demonstrates that erosion susceptibility status in the 13 sub-basins of Kansai-Kumari catchment area has been determined depending upon its morphometric, lithology, geomorphic, land use/land cover (LULC), slope and soil characteristics used by integrated micro-watershed prioritization rank which is based on susceptible capacity under geographical information system platform. Risk assessment of soil erosion was measured by hypsometric characteristic (Hi) and denudation rate (tu) to assess the geological stage of landform and risk status for conservative practices. The result shows that SB13, 2 have a high risk (tu > 90 t/km 2 /year) due to the presence of low priority rank of morphometric, geomorphic, slope, soil and high priority rank of lithological set-up and LULC but reached under the late mature geological stage (Hi > 0.35). SB3, 4, 10 have a low risk (tu < 83 t/km 2 /year) due to the presence of high priority rank of morphometric, geology, geomorphic, slope and soil types under the mature stage of geological setting (Hi > 0.5). But SB7, 8, 9 have the medium risk (tu < 85 t/km 2 /year) due to the presence of erosion-prone LULC patterns like cropland and laterite cover but having low final priority rank and old geological stage (Hi < 0.35). Therefore, erosion susceptibility does not depend on morphometric aspects but also depends on other determinant themes at the sub-basin level.

“…Morfometri adalah pengukuran konfigurasi seperti bentuk dan dimensi sistem hidrologi di permukaan bumi dengan menggunakan persamaan matematis (Kaliraj et al, 2015). Analisis morfometri banyak digunakan untuk mempelajari masalah yang berkaitan dengan pengelolaan DAS, konservasi sumber daya, dan pembangunan berkelanjutan (Javed et al, 2011;Thomas et al, 2011;Sujatha et al, 2014). Penilaian morfometri membantu menguraikan diagnosis hidrologi primer untuk memprediksi perkiraan perilaku DAS (Markose et al, 2014).…”

ABSTRAKPermasalahan daerah aliran sungai (DAS) yang bersifat multisektor, multidisplin, multipihak, dan multidimensi adalah konsekuensi dari multifungsi DAS. Kompleksitas permasalahan ini menuntut suatu sistem dan pendekatan pengelolaan sesuai karakteristik dan tipologi DAS. Penelitian ini bertujuan untuk menganalisis karakteristik dan tipologi DAS Mapili Provinsi Sulawesi Barat. Penelitian ini dilakukan dengan metode survei, pengumpulan data sekunder dan data primer. Aplikasi dari geographic information system (GIS) dengan analisis tumpang susun peta dan skoring digunakan dalam penelitian ini. Hasil penelitian menunjukkan bahwa karakterisasi biogeofisik DAS Mapili yang meliputi meteorologi, morfologi, morfometri, hidrologi, kemampuan DAS dan karakterisasi sosial ekonomi, budaya dan kelembagaan mempengaruhi sistem penerapan pengelolaan DAS Mapili. Tipologi DAS Mapili diklasifikasikan menjadi 2 tipologi DAS, yaitu: tipologi II atau DAS yang memiliki jumlah penduduk tidak padat (97 jiwa/km 2 ) dengan curah hujan yang tinggi (>2500 mm/th); dan tipologi IV atau DAS yang memiliki jumlah penduduk padat (377 jiwa/km 2 ) dengan curah hujan yang rendah (<1500 mm/th). Kedua tipologi ini memiliki karakteristik permasalahan DAS yang berbeda. Tipolgi II umumnya berada pada daerah tengah dan hulu DAS Mapili, sedangkan tipologi IV berada pada daerah hilir DAS Mapili. Kata kunci: Karakteristik DAS, tipologi DAS, GIS, DAS Mapili ABSTRACT PENDAHULUANDaerah Aliran Sungai (DAS) merupakan suatu satuan ekosistem yang memiliki peranan penting bagi kehidupan (Halengkara et al., 2012). Secara umum DAS dapat dibagi menjadi tiga bagian yaitu DAS bagian hulu, DAS bagian tengah, dan DAS bagian hilir. DAS bagian hulu berdasarkan fungsi sebagai konservasi dikelola untuk mempertahankan kondisi lingkungan DAS agar tidak terdegradasi sedangkan DAS bagian tengah dan hilir didasarkan pada fungsi

“…Based on the distribution of the stream network Kankapura watershed is divided into nine sub-watersheds. Land use and land cover (LULC) change is another important integrating parameter for watershed prioritization under the GIS platform (Altaf et al, 2014;Malik & Bhat, 2014;Sujatha et al, 2014). Slope and drainage density give valuable information on the structural aspects of drainage basin, namely, linear, aerial, and relief, which are important factors in prioritization as well as sustainable planning and management of watersheds.…”
