“…The Soil and Water Assessment Tool (SWAT), a semi-distributed and physically-based watershed-scale hydrological model developed by Arnold et al (1998), has been widely used among these models since SWAT calculates long-term impacts of land use, land management practices and buildup of pollutants with a continuous time model (Neitsch et al 2005). SWAT has been applied to show the potential impact of land management scenarios and land-use/cover and climate change impacts on the hydrology to decide better management scenarios (Bouraoui et al 2005;Mango et al 2011;Shen et al 2015;Abbaspour et al 2015;Hajihosseini et al 2019;Aboelnour et al 2020).…”

Successful water resource planning and management can be ensured by understanding the hydrological response of watersheds and non-point pollutions to land use/land cover and climatic changes. This study aims to present the effects of climate and land-use changes on hydrological processes and NPS pollutions to help prepare accurate water management policies based on their impacts. In this study, the Soil and Water Assessment Tool (SWAT) was applied to predict climate and land-use impacts on flow rate and non-point pollutions (NPS) in Namazgah Dam Basin in Turkey. Two different climate change scenarios, RCP 4.5 and RCP 8.5, and land-use scenarios, conversion of shrubland to forest and conversion of agricultural areas to the forest, were used, and statistical analyses were utilized to assess the results. At the end of this study, it was predicted that there would be an increase in phosphorus and nitrate loads and a decrease in streamflow rate.

To reveal the influence process of land use changes on runoff variation trends, this paper takes the Luojiang River of China as the study area, and the Soil and Water Assessment Tool (SWAT) model was constructed to quantitatively analyze the impact of different land uses on runoff formation in the watershed, and used the Cellular Automata-Markov (CA-Markov) model to predict future land use scenarios and runoff change trends. The results show that: (1) the SWAT model can simulate the runoff in the Luojiang River basin; (2) the runoff in the Luojiang River basin has a decreasing trend in recent 10 years, caused by the decrease of rainfall and runoff due to changes in land use; (3) the forecast shows that the land-use changes in the basin will lead to an increase in runoff coefficient in 2025. The increase of the runoff coefficient will bring some adverse effects, and relevant measures should be taken to increase the water storage capacity of urban areas. This study can help plan future management strategies for the study area land coverage and put forward a preventive plan for the possible adverse situation of runoff variation.

“…SWAT model has certain advantages in the calculation of groundwater recharge resources under the condition of underlying surface change. Based on the SWAT hydrological model, Mohamed et al [21] simulated the responses of streamflow and baseflow to climate and land use change in the Upper West Branch DuPage River basin in Illinois and the Walzem River Basin in Texas, respectively. The modeling results show that changes in streamflow and baseflow in the latter watershed seem to be more affected by urbanization than by climate change.…”

The human activities and urbanization process have changed the underlying surface of urban areas, which would affect the recharge of groundwater through rainfall infiltration and may further influence the groundwater environment. Accordingly, it is imperative to investigate the variation of hydrological cycle under the condition of underlying surface change. Based on the high-precision remote sensing data of 2000, 2005, 2010 and 2015, and Soil and Water Assessment Tool (SWAT) model, this work firstly studied the land use change and the corresponding changes in runoff generation mechanism and rainfall infiltration coefficient in Su-Mi-Huai area, Beijing, China. Meanwhile, SWAT-MODFLOW semi-loose coupling model was applied to analyze the water balance in the study area in typical hydrological years. The results showed that the area of the construction land (urban and rural residential land) increased by 1.04 times from 2000 to 2015, which is mainly attributed to the conversion of cultivated land to construction land in the plain area. This change caused the runoff in the area to increase by 7 × 106 m3, the runoff coefficient increased by 17.9%, and the precipitation infiltration coefficient was less than the empirical value determined by lithology. Compared with 2000, the average annual precipitation infiltration coefficient in 2018 decreased by 6.5%. Under the influence of urbanization process, the maximum reduction rate of precipitation infiltration recharge is up to 38%. The study investigated the response of surface runoff and precipitation infiltration recharge to land use change, which can provide helps for water resources managers to coordinate the relationship between land use change and rational water resources planning.
