Abstract Cimahi City as a part of the Upper Citarum Sub-Watershed has problems with flooding, land subsidence, and clean water crisis caused by urban development. Currently, multidisciplinary approach to management been expanded include hydrological cycle in it; one concepts that developed is water-sensitive design (WSUD). The purpose this study measure changes surface runoff result infiltratio...
Flood prediction is very important in land and water resources management. Many flood disasters could be mitigated with adequate preparedness especially urban watershed. This study assessed the runoff potential of Opa watershed Southwest Nigeria using remote sensing Soil Conservation Service or SCS curve number (CN) techniques. The 2007 NigSat image year was classified into different cover clas...
Nowadays, a major issue is land-use change by urban development that alters the catchment response to meteorological events. Urban basins have less storage capacity and more rapid runoff, so rivers rise quickly during storms higher peak discharge rates than rural catchments. An exemplary case of this situation city Milan (northern Italy) its whole territory extends towards north collecting mete...
One of the major problems confronted by the hydrologists for many years is the prediction of runoff from a given basin for a known rainfall. In this situation, development of a rainfall runoff model is important in Veeranam tank catchment located at latitude 11° 15’00” and longitude 79° 30’00’ E in Cuddalore District of Tamilnadu, India. By considering the above said aspect the rainfall-runoff ...
Hydrological models for evaluating and predicting the amount of available water in basins, flood frequency analysis, and developing strategies to deal with destructive floods are expanding daily. In this study, HEC-GeoHMS and Arc Hydro extensions in ArcGIS software and the HEC-HMS model were used to simulate design flood hydrographs in the Aydooghmush basin in the northwest of Iran. SCS-CN, SCS...
Planning and management of water resources is crucial to enhance agricultural productivity ensure food security in drylands. For this, adaptable reliable runoff prediction models are urgently needed support harvesting irrigation development. In this study we explored the potential Curve Number (CN) method estimate daily surface from representative land use types conditions Tigray (north Ethiopi...
introduction simulations of river flow and understanding different components of hydrologic cycle are important for programming of the conservation aspects of water resources. since the study area is located in the site of dam construction, the estimation of rainfall runoff and sediment yield are very important for better management of water resources. therefore, in this study, the swat model w...
