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

ÖzetÖzellikle tarım ve hayvancılık kaynaklı yayılı kirleticilerin su havzalarındaki davranışlarını tahmin etmeye yönelik modelleme çalışmaları, son yıllarda gittikçe artarak dikkati çekmektedir. Çoğu zaman sadece önlem amaçlı kullanılan antibiyotikler, hayvan yetiştiriciliğinde en yaygın olarak tercih edilen ilaç türlerinden biridir. Antibiyotiklerin kayda değer fraksiyonları hayvan atığında ortaya çıktığı için; tarımsal arazilere hayvan atıklarının gübre olarak uygulanmasını takiben, antibiyotikler gübreden toprağa geçerek toprak kalitesini, aynı zamanda yüzeysel akışla yüzey sularına taşınarak su kalitesini olumsuz etkileyebilmektedirler. Bu durum su temininde önemli rol oynayan havzaların planlanması ve yönetimi için modelleme çalışmalarının geliştirilmesini gerekli kılmıştır. Coğrafi Bilgi Sistemleri (CBS), mekansal verileri elde etmede sağladığı kolaylık ve çok sayıda farklı türdeki veriyi haritalandırma özelliği ile havza modelleme çalışmalarında başvurulan önemli araçlardan bir tanesi olmuştur. Besi maddelerinin taşınımı ve su kalitesi üzerine etkilerini inceleyen CBS tabanlı modelleme yaklaşımları literatürde bulunmaktadır; ancak benzer çalışmalar ağır metaller ve antibiyotikler için sınırlı sayıdadır. Bu çalışmanın amacı literatürde yer alan, başta antibiyotikler olmak üzere ağır metal ve besi maddeleri gibi önem arz eden kirleticilerin su ortamlarında ve havzalarındaki taşınımındaki modelleme yaklaşımlarını özetlemek ve değerlendirmektir. AbstractModelling studies predicting the fate and transport of non-point-source pollutants, especially from agricultural and pasture lands, have gained increasing attention during the recent years. Veterinary antibiotics are one of the most widely preferred drugs for animal husbandry. Since a considerable fraction of antibiotics is excreted in animal waste; following to application of animal waste as manure on agricultural lands, antibiotics can affect both soil and water quality by leaching from manure to soil, and by being transported to surface waters via runoff, respectively. This necessitates the development of modeling approaches for planning and management of catchments that play a significant role on water supply. Geographical Information Systems (GIS) has become an important methodological tool in catchment modeling, with the facilities to obtain spatial data, and advanced visualization of numerous data types as different map layers. GIS-based modeling approaches concerned with nutrient transport and water quality are encountered in literature; however, similar studies are scarce for heavy metals and antibiotics. The aim of this study is to provide a summary and evaluation of the existing modelling approaches from the literature that are used for modelling the fate and transport of emerging pollutants, particularly antibiotics, heavy metals and nutrients, in watersheds.

“…(2) Trends in threshold definition methods in the watershed delineation process Due to advances in desktop GIS capabilities, programming languages, and data availability, many watershed geographical information system (GIS)-based applications have been developed since the early 1990s. Hydrological modeling is a welldeveloped technology that has been widely applied with GIS in various studies, in particular those related to geomorphology, soil science, hydrology, and land use planning 7) . In hydrological modeling, Digital Elevation Models (DEMs) are important and useful sources for automatically generating the flow direction, flow accumulation, stream direction, drainage line, catchment, sub-watershed, and watersheds.…”

With increased awareness of the importance of land use change at both local and regional scales within watershed-based planning, the study of land use analysis has become the focus of several international scientific endeavors. Since land use change has become a major issue in this century due to global urbanization, the study of watershed-based land use analysis will play an important role in a sustainable future. This paper undertakes a comprehensive review of watershed-based land use analysis to clarify the research trends in this area, including basic tools, factors, methodologies, study regions, scales and areas. Land use detection methods, land use modeling and thresholds in watershed delineation were identified as the fundamental tools, while land use policies, water quality, surface runoff, flooding control, land use suitability and land allocation analysis, and landscape structure were identified as the main factors in watershed-based land use planning.
