Abstract Morphometric analysis is a powerful tool to understand the hydrological process quantitatively and main requirement determine characteristics of watershed. drainage Sedayu River Sub-watershed, Semaka District, Tanggamus Regency, Lampung Province was carried out using Digital Elevation Model (DEM) data. The primary data used aerial photography drones, location photos representing waters...

Cikeruh-Citarik sub-watershed is a part of the upstream zone Citarum watershed which classified as with critical conditions in West Java. The change land use side effect increasing population causes degradation watershed. Land-use without considering any conservation rules leads to erosion, becoming criticality indicator. Erosion can be minimized by using prediction model predict amount erosion...

Abstrak: Upaya manusia yang memiliki hasrat untuk selalu meningkatkan perekonomian tentunya harus disertai upaya tetap menjaga kelestarian lingkungan. Penambahan jumlah penduduk dan aktivitasnya berimplikasi pada perubahan penggunaan lahan berujung kualitas Salah satu dampak terjadi adalah terjadinya erosi. DAS di Indonesia mengalami potensi erosi Citarum. Sub Cirasea merupakan bagian berada hu...

Acid deposition during the 20th century caused widespread depletion of available soil calcium (Ca) throughout much of the industrialized world. To better understand how forest ecosystems respond to changes in a component of acidification stress, an 11.8-ha watershed was amended with wollastonite, a calcium silicate mineral, to restore available soil Ca to preindustrial levels through natural we...

Management of water resources in watershed determined by avaibility accurate rainfall data. The study rationalization recorded density result the suggestion amount and placement watershed. was manage Watershed Bango with total area 246,4 km2 using Kagan-Rodda method WMO Standard. analysis Standard, 100-250 km2/rainfall shown that none existing Sub-Watershed are qualified. giving recommendation ...

Watershed prioritization has become increasingly crucial for managing natural resources, especially the watersheds. A useful decision support tool to provide appropriate weights different morphological attributes with lineage soil erosion is required identify environmentally stressed areas watershed resources. This study examines Western Nayar delineation and further examination of watershed’s ...

Watershed-based stormwater management (WSM) has been proposed as more effective for stormwater management than traditional methods of controlling stormwater, which are carried out based on jurisdictional lines at the parcel-scale. Because WSM considers the watershed as a total unit, this method is considered to be more effective in reducing problems associated with stormwater management includi...

The Cirasea sub-watershed is one of the sub-watersheds that has an important role in management Upper Citarum watershed. decline land use impact on hydrological system watershed, which caused by changes use. land-use change determined analyzing results classification using Maximum Likelihood Classification (MLC) algorithm QGIS software. Land Landsat Image 2009-2019. include forest, secondary bu...

Traditionally, stream and sub-watershed characterization in GIS has been accomplished using a DEM-based terrain analysis approach; however, there is a large amount of existing vector hydrographic data difficult to accurately reproduce using DEMs. WaterNet is a GIS/hydrologic application for the integration and analysis of stream and sub-watershed networks in vector format. Even with vector data...
