Abstract The quantification of uncertainty in the ensemble-based predictions climate change and corresponding hydrological impact is necessary for development robust adaptation plans. Although equifinality modeling has been discussed a long time, its influence on analysis not studied enough to provide definite idea about relative contributions contained both multiple general circulation models (GCMs) multi-parameter ensembles projections. This study demonstrated that multi-GCM ensemble...
The Environmental Policy Integrated Climate (EPIC) and Agricultural Policy/Environmental eXtender (APEX) models have been developed to assess a wide variety of agricultural water resource, quality, other environmental problems. EPIC model is designed be applied at the field scale. APEX direct extension that can also fields as well more complex multi-subarea landscapes, whole farms, watersheds. This article describes key components APEX, including different options for simulating surface...
<abstract> <b><sc>Abstract.</sc></b> Hydrologic and water quality (H/WQ) models are widely used to support site-specific environmental assessment, design, planning, decision making. Calibration validation (C/V) fundamental processes demonstrate that an H/WQ model can produce suitable results in a particular application. However, the lack of comprehensive guidelines has led use ad hoc, inconsistent, incomplete C/V processes, which have made it difficult interpret myriad published modeling...
Inappropriate use of land and poor ecosystem management have accelerated degradation reduced the storage capacity reservoirs. To mitigate effect increased sediment yield, it is important to identify erosion-prone areas in a 287 km2 catchment Ethiopia. The objectives this study were to: (1) assess spatial variability yield; (2) quantify amount delivered into reservoir; (3) prioritize sub-catchments for watershed using Soil Water Assessment Tool (SWAT). SWAT model was calibrated validated...
Although Ethiopia has abundant land for irrigation, only a fraction of its potential is being utilized. This study evaluates suitability lands irrigation using groundwater in GIS-based Multi-Criteria Evaluation (MCE) techniques order to enhance the country's agricultural industry. Key factors that significantly affect evaluated this include physical features (land use, soil, and slope), climate (rainfall evapotranspiration), market access (proximity roads market). These were weighted...
This study assessed the impact of climate change on water availability and variability in two subbasins upper Blue Nile basin Ethiopia. Downscaled future data from HadCM3 A2 (medium-high) B2 (medium-low) emission scenarios were compared to observed for a baseline period (1961–1990). The scenario representing was used predict as input hydrologic model estimate streamflow at three time horizons: 2020–2045, 2045–2070 2070–2100. Results suggest that medium-high best represents local rainfall...
Agricultural expansion and urban development without proper soil erosion control measures have become major environmental problems in Cambodia. Due to a high population growth rate increased economic activities, land use cover (LULC) changes will cause disturbances, particularly erosion. This research aimed estimate total amounts of loss using the Revised Universal Soil Loss Equation (RUSLE) model within Geographic Information System (GIS) environment. LULC maps Japan International...
The effects of Low Impact Development (LID) practices on urban runoff and pollutants have proven to be positive in many studies. However, the effectiveness LID can vary depending different patterns. In present study, performance was explored under three land uses with forms: (1) a compact high-density form; (2) conventional medium-density (3) conservational form. Soil Water Assessment Tool (SWAT) used model development performed reflect hydrologic behavior by application practices. Rain...
Soil erosion is exacerbated by unsustainable land-use activities and poor management practices, undermining reservoir storage capacity. To this effect, appropriate estimation of sediment would help to adopt sustainable best practices that lead efficient operations. This paper aims investigate the spatial variability yield, amount delivery into reservoir, sedimentation in Koga Reservoir using Water Assessment Tool (SWAT). Sediment yield entered were also estimated a rating curve, providing an...
Estimating the potential land resources suitable for irrigation and evaluating possible impact of climate change on suitability is essential planning a sustainable agricultural system. This study applied GIS-based Multi-Criteria Evaluation (MCE) technique to evaluate in Ghana baseline period (1990 2010) future time horizons 2050s (2041 2060) 2070s (2061 2080). Key factors considered include biophysical features (such as climate, use, soil, slope) socioeconomic proximity roads population...
This study investigates multi-dimensional impacts of adopting new technology in agriculture at the farm/village and watershed scale sub-Saharan Africa using Integrated Decision Support System (IDSS). Application IDSS as an integrated modeling tool helps solve complex issues agricultural systems by simultaneously assessing production, environmental, economic, nutritional consequences technologies for sustainable increases food production use scarce natural resources. The approach was applied...
Abstract The precise and reliable simulation of hydrologic hydraulic processes is important for efficient flood forecasting warning. study proposes a real-time system which integrates coupled hydrological-hydraulic modeling system, weather station network, stream gauges in web-based visualization environment. An automated procedure was developed linking dynamically terrestrial rainfall-runoff river hydraulics by coupling the SWAT hydrological model HEC-RAS model. trialed Vu Gia – Thu Bon...
The Agricultural Policy/Environmental eXtender (APEX) model is widely used for evaluating agricultural conservation efforts and their effects on soil water. A key component of APEX application in Korea simulating the water quality impacts rice paddies because agriculture claims largest cropland area country. In this study, a computational module called APEX-Paddy (National Academy Sciences, Wanju, Korea) developed to simulate with considering pertinent paddy management practices, such as...
