“…It was developed to evaluate the effects of alternative management decisions on water resources and diffuse pollution in mesoscale and large river basins. A detailed history of SWAT's development can be found in Gassmann et al (2007) and Williams et al (2008). Here, it is only outlined briefly.…”

“…The first paper, written by experts involved in the model development (Williams et al, 2008), presents an overview of the history of SWAT development. The first author has been working in this area since the mid-1960s, but the history started even earlier, in the mid-1930s, when it was decided that the US Soil Conservation Service evaluate experimentally the hydrological response from watersheds influenced by various management practices.…”

“…The development of SWAT is a continuation of United States Department of Agriculture-Agricultural Research Service (USDA-ARS) modeling experience that spans a period of over 30 years [17,18]. Accurate calibration of hydrologic models (including SWAT) is very important in assessing the water budget of a watershed for sustainable water resources management [19].…”

Calibration and validation of process based hydrological models are two major processes while simulating the water balance components of watershed systems. However, these processes need a better understanding of the parameters which influence hydrologic processes within the system. In this study, we used SWAT model to simulate the stream flow for Skunk Creek (SK) watershed in South Dakota for the period from 1980-2000. Model calibration and validation were performed for both daily and monthly time periods using SUFI-2 within SWAT-CUP using 24 parameters selected from past available literature. Our calibration outputs for the period from 1987-1994 showed a good correlation between observed and model simulated values with NSE=0.56 and R 2 =0.70 for daily simulation. However, the model showed a better performance for monthly simulation with NSE and R 2 values of 0.84 and 0.84 respectively. During validation period (1995)(1996)(1997)(1998)(1999)(2000), the NSE and r 2 values were 0.55 and 0.44, respectively for daily simulation and these statistical values were 0.76 and 0.77, respectively for monthly time step. Following calibration, the overall effect of each parameter used was ranked using global sensitivity function within SWAT-CUP. From the analysis, SOL_AWC was found to be the most sensitive parameter with absolute t-value of 17.50 and p-value of 0.00 to simulate the stream flow of the SK watershed. The CH_K2 was observed as the least sensitive parameter with t-statistic and p-value of 0.02 and 0.97, respectively. It was concluded from the study that coupling of the SWAT and SWAT-CUP made the calibration process quicker and reliable to simulate local hydrology within the watershed.

“…In combination with climate scenarios from general circulation models (GCMs), hydrological models are effective simulation tools to evaluate climate change effects on water resources at different spatial scales (Ficklin et al 2009, Moradkhani et al 2010, though uncertainty may exist in simulation results (Arnell 2011. The Soil and Water Assessment Tool (SWAT) is one of the most popular watershed modelling tools (Gassman et al 2007, Williams et al 2008. Numerous researchers have confirmed that SWAT is suitable for simulating climate change processes.…”

Climate change impacts on the availability of water resources. Projection of hydrological response to temperature change is valuable for water management. Such response may be complex and uncertain at the watershed scale and differences may exist between low and high latitudes. A simulation experiment was achieved by using SWAT modelling in the upstream watershed of Dongjiang River, South China. After calibration, the model was found appropriate for hydrological simulation in the study area and was run from 1995 to 2004 under a series of temperature change scenarios to reveal the response of streamflow and loads of sediment and nutrients. For a temperature increase of 3• C, streamflow, sediment and total phosphorus decreased by 5.2, 7.7 and 2.2%, respectively. Linear temperature change seemed to have a linear hydrological response. Nutrient deficiency was still the primary vegetation stress compared with water availability and temperature stress under rising temperatures. Comparison with previous research showed that two southern subtropical watersheds (one upstream and one downstream) gave different hydrological responses. Sediment and inorganic nitrogen loads decreased in the upstream watershed, but increased in the downstream one, when temperature increased. Under the warming scenarios, streamflow and sediment loads decreased throughout the year, especially during the wet season, which is different from results at high latitudes. Nutrient export decreased in April-June, but increased in the remaining months. Simulation results should be applied with caution in water resources management, as simulated climate change had variable hydrological influence in different regions and seasons.Key words temperature change; southern subtropics; streamflow; sediment; nutrient loading; SWAT Effets divers des modifications de température sur le débit et la pollution diffuse dans les régions subtropicales de Chine méridionale par simulation SWAT Résumé Effets du changement climatique sur la disponibilité des ressources en eau. Anticiper les effets hydrologiques des changements de température est utile pour la gestion de l'eau. Une telle réponse peut être complexe et incertaine à l'échelle des bassins versants et il peut exister des différences entre les basses et les hautes latitudes. Une expérience de simulation a été réalisée par une modélisation SWAT de l'amont du bassin versant de la rivière Dongjiang, en Chine méridionale. Après calage, le modèle a été jugé approprié pour la simulation hydrologique dans la zone d'étude, et a on l'a fait tourner de 1995 à 2004 pour une série de scénarios de changement de température afin de déterminer la réponse de l'écoulement et des charges de sédiments et de nutriments. Lorsque la température a été augmentée de 3• C, les débits, les sédiments et le phosphore total ont respectivement diminué de 5,2, 7,7 et 2,2 %. Un changement de température linéaire semble avoir une réponse hydrologique linéaire. La carence en éléments nutritifs s'est révélée être le principal stress pour la ...
