Research ArticleOpen accessIn the keywordsInvestigation of Climatological Components on Runoff Modeling using SWATHamid-Reza Rabiefar, Sayed-Reza Alvankar, Kaveh Ostad-Ali-AskariIt was planned most hydraulic projects, for instance barriers, it was defined the overflow of the rivers. If the river absences any position to measure the yield, the hydraulic models can be utilized to estimate it. SWAT is widely-used computerized mockups. It was required to feed such influential climatological information as precipitation, temperature, wind speed, solar radiation and relative humidity, … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 30 Dec 2020 · 6,114 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Land Cover on Streamflow Variability in a Small Iowa Watershed: Assessing Future VulnerabilitiesKeith Schilling, Matthew Streeter, Kasey Hutchinson et al.Agricultural expansion and urbanization, coupled with climate change represent major threats to the sustainability of river ecosystems and infrastructure. In this study, we evaluated how subbasins with different dominant land covers within the 27.5 km2 Clear Creek, IA watershed affect key hydrologic indicators. Hydrologic output from two stream gages and a calibrated Soil Water Assessment Tool (SWAT) model were used … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 6 Jul 2015 · 8,367 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFuture Water Budgets and Water Supply Stress under Climate Change and Urbanization in the Upper Neuse River Basin, North Carolina, USAMichelle Tong Sun, Ge Sun, Chong Liu et al.Urbanization and climate change are the two major threats to watersheds and the environment in the United States. It is imperative to understand the sensitivity of hydrologic responses to climate and urbanization across different physiographic regions in order to formulate sound watershed management strategies and policies. This study evaluated a watershed water balance model, Water Supply Stress Index (WaSSI), with … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 30 Jun 2015 · 7,162 accessesView PDF Cite

Research ArticleOpen accessIn the abstractApplication of Soil and Water Assessment Tool Model to Estimate Sediment Yield in Kaw LakeD. Alemayehu, R. Srinivasan, P. DaggupatiKaw Lake is one of the reservoirs built by the Army Corps of Engineers in 1976 for the purpose of flood control, recreation, water supply, navigation and fish and wildlife conservation. The Arkansas River flows from Colorado and Kansas before reaching Oklahoma. As it passes through these states, the water carries various kinds of pollutants such as metals from mine … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 16 Dec 2014 · 8,271 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCLIMATE CHANGE IMPACT ASSESSMENT ON WATERSHED HYDROLOGY: A COMPARISON OF THREE APPROACHESSomsubhra Chattopadhyay, Manoj K. JhaSeveral methods of impact assessment have been developed over the years which basically incorporate future climate projections of atmospheric-ocean circulation based climate models into the simulation of land surface hydrological processes. This study attempted to evaluate three methods of climate change impact assessment: (a) Frequency perturbation method, (b) direct method and (c) delta change method. A well-calibrated hydrologic model, Soil … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 27 Mar 2014 · 8,597 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPotential Zones of Peruvanthanam and Valiyathodu Sub-Watersheds of Manimala River BasinVadakkepurakkal Rekha, Aikara Varkey George, Rita MendezGroundwater is a dynamic and replenishable natural resource. But in hard rock terrains, its availability is of limited extent. In sub-watershed studies, remote sensing and GIS techniques have the advantages of spatial, spectral and temporal data, covering large and inaccessible areas within a short span of time. Thus this technique has become a very handy tool in assessing and monitoring … …American Journal of Environmental Sciences, Vol. 9, Issue 1 · 20 Feb 2013 · 7,389 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUse of 137Cs Activity to Investigate Sediment Movement and Transport Modeling in River Coastal EnvironmentM. E. Toriman, Muhamad Barzani Gasim, Zulkifli Yusop et al.Conflicts between human and environment always triggered to sedimentation and erosion problems within the coastal areas, Therefore understanding sediment transport processes in a river estuary and coastal waters was important when studying sediment transport and mobility within the river coastal environment. This article aims to investigate the sediment transport and mobility of the Kemaman River estuary, Terengganu Malaysia. In this … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 22 Jun 2012 · 7,764 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSoil Erosion Prediction Based on Land Use Changes (A Case in Neka Watershed)Karim Solaimani, Saeid Modallaldoust, Sedigheh LotfiProblem statement: Land use change has transformed a vast part of the natural landscapes of the developing world for the last 50 years. Land is a fundamental factor of production and though much of the course of human history, it has been tightly coupled with economic growth. Soil erosion by water is one of the most important land degradation processes … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 2 · 30 Jun 2009 · 8,447 accessesView PDF Cite
