Runoff And Sediment Yield

Land-use change is one key factor influencing the hydrological process. In this study, the Hun River Basin (HRB) (7919 km2), a typical alpine region with only four gauge meteorological stations, was selected as the study area. The China Meteorological Assimilation Driving Datasets for the SWAT model (CMADS), widely adopted in East Asia, was used with the Soil and Water Assessment Tool (SWAT) model to simulate runoff and sediment yield responses to land-use change and to examine the accuracy of CMADS in the HRB. The criteria values for daily/monthly runoff and monthly sediment yield simulations were satisfactory; however, the validation of daily sediment yield was poor. Forestland decreased sediment yield throughout the year, increased water percolation, and reduced runoff during the wet season, while it decreased water percolation and increased runoff during the dry season. The responses of grassland and forestland to runoff and sediment yield were similar, but the former was weaker than the latter in terms of soil and water conservation. Cropland (urban land) generally increased (increased) runoff and increased (decreased) sediment yield; however, a higher sediment yield could occur in urban land than that in cropland when precipitation was light.

To investigate the impacts of land-use patterns on the sediment yield characteristics in the upper Huaihe River, Xixian hydrological controlling station was selected as the case study site. Soil and Water Assessment Tool (SWAT) model was used to simulate land-use change effects on sediment yield by the use of three-phase (1980s, 1990s and 2000s) land-use maps, soil type map (1:200000) and 1987 to 2008 daily time series of rainfall from the upper Huaihe River basin. On the basis of the simulated time series of daily sediment concentration, land-use change effects on spatio-temporal change patterns of soil erosion modulus. The results revealed that under the same condition of soil texture and terrain slope the advantage for sediment yield was descended by woodland, paddy field and farmland. The outputs of the paper could provide references for soil and water conservation and river health protection in the upper stream of Huaihe River.

Runoff And Sediment Yield

Land-use change has a significant influence on runoff process of any watershed, and the deepening of this theme is essential to assist decision making, within the scope of water resources management. The study was conducted for Mundaú River Basin (MRB) using the Soil and Water Assessment Tool (SWAT) model. The study aims to assess the issue of land-use change and its effect on evapotranspiration, surface runoff, and sediment yield. Input data like land use, topography, weather, and soil data features are required to undertake watershed simulation. Two scenarios of land use were analyzed over 30 years, which were: a regeneration scenario (referring to use in the year 1987) and another scene of degradation (relating to use in the year 2017). Land use maps for 1987 and 2017 were acquired from satellite images. Overall, during the last three decades, 76.4% of forest was lost in the MRB. The grazing land increased in 2017 at a few more than double the area that existed in 1987. Changes in land use, over the years, resulted in an increase of about 37% in the water yield of MRB. Changes have led to increased processes such as surface runoff and sediment yield and in the decrease of evapotranspiration. The spatial and temporal distribution of land use controls the water balance and sediment production in the MRB.

In this study, Soil and Water Assessment Tool (SWAT) model was used to simulate land-use change effects on water quantity in the upper Huaihe river basin above the Xixian hydrological controlling station with a catchment area of 10,190 km2 by the use of three-phase (1980s、1990s、2000s) land-use maps, soil type map (1:200000), 1980 to 2008 daily time series of rainfall from the upper Huaihe river basin. On the basis of the simulated time series of daily runoff, land-use change effects on spatio-temporal change patterns of runoff coefficients and runoff modules were investigated. The results revealed that under the same condition of soil texture and terrain slope the advantage for runoff generation and the sensitivity of rainfall-runoff relationship to rainfall descended by farmland, paddy field, woodland.The outputs could provide important references for soil and water conservation and river health protection in the upper stream of Huaihe river.

The Srepok river basin (28,600km2) is located in the Central Highlands of Vietnam. There are many critical issues for soil and water resource management in the basin. Therefore, to make suitable adaptation plans, decision makers need to understand the extent of the potential impact of both climate change and human activity on local soil and water resources. The objective of this chapter was to investigate changes in stream flow, sediment load, and hydrological processes resulting from land use change and climatic variation. Plausible scenarios of land use change developed in a GIS environment based on current conditions, information from the area, and climate change scenarios were built on outputs of GCMs from the SEA-START. These changes were then inputted into SWAT model to project future hydrological variables. Results demonstrated that stream flow was predominant, followed by evapotranspiration. Groundwater was more predominant than surface water. This has been one of the best outstanding advantages in the Srepok watershed.

The overall goal of this study is to evaluate the effect of land use on reservoir’s sediment yield by applying Arc SWAT model interface with GIS and identify the vulnerable sub basin in Neshi dam watershed. Different input data were collected from different sources including Ministry of Water, Irrigation and Energy, and Ethiopia National Meteorological Agency. The study was done using historical records of nineteen years for Neshi Watershed. The calibrated flow and sediment for the 1992-2001 years gave R2 0.77, 0.92 and NES 0.64, 0.96, respectively. The validated flow and sediment for the 2002-2008 years gave R2 0.72, 0.93 and NES 0.75, 0.95, respectively.In this study the SWAT model yields average annual sediment load of 634.49, 516.82 and 542.56 ton/ha/yr for land use change of 1990, 2010 and 2017, respectively at Neshi outlet dam site. Therefore, the issue of land use change impact on sediment yield on reservoir as part of the integrated adaptation mitigation measures program in order to achieve sustainable development is very relevant. The output of this study can help planners, decision makers and other stakeholders to plan and implement appropriate soil and water conservation strategies.

The Ciliman Watershed is one of the watersheds in Kabupeten Lebak and Kabupaten Pandeglang with a total area ± 500 km2. According to report of Badan Nasional Penanggulangan Bencana (BNPB) Serang City, flooding often occurs in the Ciliman watershed because of the overflow of the Ciliman tributaries, this occurs because of the conversion of land use in the upstream area of Ciliman watershed so that during the rainy season, rainwater does not seep into the ground but directly into runoff. The aims of the research is to simulate several soil and water conservation as an effort to better manage the Ciliman watershed and determine the best land use scenario in accordance with the biophysical Ciliman watershed. This study applied SWAT model as a tool to simulate several soil and water conservation technical at Ciliman watershed. The scenarios simulated were: 0) existing condition, 1) application of forest area functions, 2) application of soil and water conservation techniques using RTK RHL, 3) application of regional spatial planning (RTRW). The results showed that scenario 2 (RTK RHL) was the best scenario by overall. Scenario 2 can reduce the Qmax/Q min ratio by 31.63% compared to other scenarios. And also can reduce coefficient of runoff by 24% and direct runoff by 23.55% and increase baseflow by 16.20% and water yield by 1.77%.
