Abstract The likelihood of future global water shortages is increasing and further development of existing operational hydrologic models is needed to maintain sustainable development of the ecological environment and human health. In order to quantitatively describe the water balance factors and transformation relations, the objective of this article is to develop a distributed hydrologic model that is capable of simulating the surface water (SW) and groundwater (GW) in irrigation areas. The model can be used as a tool for evaluating the long-term effects of water resource management. By coupling the Soil and Water Assessment Tool (SWAT) and MODFLOW models, a comprehensive hydrological model integrating SW and GW is constructed. The hydrologic response units for the SWAT model are exchanged with cells in the MODFLOW model. Taking the Heihe River Basin as the study area, 10 years of historical data are used to conduct an extensive sensitivity analysis on model parameters. The developed model is run for a 40-year prediction period. The application of the developed coupling model shows that since the construction of the Heihe reservoir, the average GW level in the study area has declined by 6.05 m. The model can accurately simulate and predict the dynamic changes in SW and GW in the downstream irrigation area of Heihe River Basin and provide a scientific basis for water management in an irrigation district.

Water Measurement

Abstract: In human life, water resources are inseparable. In recent years, China's population growth has accelerated, and the industrial level has been continuously improved, resulting in the rapid use and waste of water resources. The protection and rational distribution of water resources is the most pressing issue in China's water resources. At present, the water measuring facilities of the U-shaped channel mainly include a straight wall measuring pool, a parabolic throat measuring pool and a long throat measuring pool. In view of the problems in irrigation measurement, the empirical water measurement of basic open channel and automatic flow measurement system in irrigation district is summarized to improve the accuracy, fairness and rationality of water measurement, and promote irrigation district management to a higher level.
