Research and Application of SWAT Model in Basin Without Reservoir Outflow Data
Published 2021-01-01“…Due to human factors such as reservoirs,the hydrological cycle of natural basins will change.During the establishment of a basin hydrological model,the reservoir factors should be considered.However,the lack of reservoir outflow data will affect the accuracy of the model to a certain extent.Based on the SWAT (Soil and Water Assessment Tool) distributed hydrological model,long-term daily-scale hydrological model under natural conditions,and Muskingum principle,this paper establishes the upstream and downstream flow response relationships,and obtains the reservoir outflow to improve the accuracy of the simulated hydrological cycle,applies the method to the Guijiang River Basin in Guilin City,Guangxi Zhuang Autonomous Region for verification,and identifies and verifies the hydrological model parameters of the Guijiang River Basin through SWAT-CUP.The results show that the simulated runoff at each hydrological station after the availability of the reservoir outflow is close to the measured runoff.Among them,the monthly runoff simulation evaluation factors R<sup>2</sup> and NS of Guilin Station are increased from 0.85 and 0.83 to 0.98 and 0.93 respectively,and the accuracy of the model is effectively improved,which provide technical means for hydrological management of the Guijiang River Basin.…”

Analysis of Current State of SWAT Model Research Based on Bibliometrics
Published 2023-01-01“…In order to gain insights into the latest advancements,focal areas,and future directions in SWAT model research,this paper conducted a bibliometric analysis of its applications in eco-hydrological modeling by using the Web of Science<sup>TM</sup> core database and the VOSviewer visualization software.The findings reveal that from 2000 to 2022,there has been a general increase in publications related to the SWAT model.Research efforts have primarily concentrated on three main areas:firstly,the hydrological simulation applications of the SWAT model to enhance scientific water resource management;secondly,investigations into the mechanisms of hydrological responses to climate and human activities,offering theoretical support for flood disaster prediction and response;lastly,studies on water quality simulation and optimal management strategies,providing theoretical foundations for the prevention and control of agricultural non-point source pollution.The distribution of research teams has shifted from concentrated to more dispersed.Future SWAT research will prominently focus on water resource management,hydrological response processes,and water quality simulation.…”

Applicability of CMADS in Runoff Simulation of Huotong River Basin Based on SWAT Model
Published 2021-01-01“…The scarcity of meteorological data leads to the limitation of hydrological model research,which also exists in small and medium-sized rive basins along the southeastern coastal areas of China.The China meteorological assimilation dataset (CMADS) is the available meteorological dataset,which aims to filling the gap of data scarcity in hydrological model.Therefore,it is particularly important to verify the applicability of this dataset in runoff simulation based on SWAT model.Taking the Fujian Huotong River basin as the object,and the data of the survey station as the reference,this paper evaluates the applicability of CMADS by using the data consistency evaluation,the test coefficient of runoff simulation based on SWAT model and the spatial distribution of hydrological elements.The results show that:The spatial distribution of precipitation in the two types of data is consistent,and the correlation of temperature data is high.The R<sup>2</sup> and NSE coefficients of the monthly and daily runoff simulation results based on SWAT model obtained from the CMADS and the survey stations are satisfactory.The hydrological components of the CMADS model have little deviation from that of the survey station with consistent spatial distribution.Therefore,it can be concluded that the CMADS has good applicability in the runoff simulation of representative river basins along the southeast coastal area of China.…”

Study on Maximum Scour Depth at River Reach of Shantou Bay Subsea Tunnel Project
Published 2022-01-01“…This paper studies the flow pattern and riverbed scouring at the river reach of Shantou Bay Subsea Tunnel Project through the river model test and analyzes the maximum scour depth of the riverbed near the project under unfavorable hydrological conditions.The results show that the maximum flood velocity at the tunnel section is above 1.5 m/s under unfavorable hydrological conditions,and riverbed scouring is obvious in the main channels of the left and right branches.The maximum scour depth of the riverbed at the tunnel site is 6.40 m and 5.24 m under the once-in-three-century and once-in-a-century hydrological conditions,respectively.The envelope results of the maximum scour depth at the tunnel section can provide a basis for determining the reasonable buried depth of the project,and the research results can provide reference for similar projects in Shantou Bay.…”

Multi-Objective Optimization and Decision Making for Spatial Layout of Sponge Facilities
Published 2023-01-01“…The risk of urban flooding and non-point source pollution intensifies due to climate change and urbanization.Sponge city,a nature-based solution to adapt to climate change,is being promoted in China.How to plan and design sponge facilities to give full play to their diversified benefits becomes the key to effectively constructing a sponge city.In this study,a multi-objective optimization coupling model was constructed based on the NSGA-Ⅲ algorithm and SWMM.TOPSIS method was used to screen out the optimization scheme,and the hydrological benefits,environmental benefits,and irrigation water demand of the optimization scheme under hydrological years with high,normal,and low flows were analyzed.The method was applied to Dongshan Campus of Shanxi University.The results indicate that the three optimal schemes show good hydrological and environmental benefits under typical hydrological years,with an average annual runoff reduction rate of 68.3% and an SS reduction rate of 83.7%.Scheme S1 is the closest to the ideal scheme and has the largest irrigation water demand, which is about 228 000 m<sup>3</sup> per year. …”
