Research on the Construction of Small River Channel Dredging and Farmland Utilization System in the Southern Region
The aim of this study is to explore the dredging problem of small river channels in the southern region and the effective construction of farmland utilization systems,in order to improve the ecological environment of river channels,strengthen water resource management,and improve farmland irrigation efficiency.By establishing an accurate three-dimensional numerical model to simulate the flow characteristics and dredging effect of the riv-er,this study has set detailed geometric parameters of the river and performed grid independence verification to ensure the accuracy and reliability of the model.The research results indicate that by properly designing river dredging and farmland utilization systems,water flow quality and irrigation water utilization efficiency can be sig-nificantly improved.After river dredging,water transparency is increased by 30％,and farmland irrigation effi-ciency is improved by 25％.Future research will explore the adaptability of the system under different environ-mental conditions and the impact of heavy metals in industrial wastewater treatment.This study provides scientific basis and optimization direction for small-scale river management and farmland utilization in the southern region,and has important theoretical significance and practical value.In addition,the research also provides scientific ba-sis and optimization direction for future river management and agricultural irrigation systems,which has important theoretical significance and practical value.
