Key Laboratory of Water Conservancy and Water Resources of Anhui Province, Water Resources Research Institute of Anhui Province and Huaihe River Commission, Ministry of Water Resources of the People's Republic of China, Hefei, 230088, China.

As one of the important characteristics of river morphology, river sinuosity has a direct impact on the river water quality and self-purification capacity. In the present study, 4 physical river channel simulation models using circulating water with a sinuosity of 2.2, 1.

This study examined five ponds and three ditches in the Shufengwan Sports Park in a new urban district of Hefei City, from which surface-layer sediments and overlying water samples were collected during autumn, winter, and summer. The equilibrium phosphate concentrations (EPC) of the sediments and its response to exogenous carbon or nitrogen were then measured. The resulting EPCvalues were used to assess the risk of phosphorus release by the sediments.

Article Synopsis
  • A study investigated maize evapotranspiration under drought conditions using large-scale weighing lysimeters in Anhui Province, China, aiming to analyze how different drought levels impact water needs.
  • The researchers optimized crop coefficients using a genetic algorithm and found that a slight early-stage water deficit could enhance maize tolerance to drought, but prolonged stress had more severe consequences during critical growth phases.
  • Results showed significant improvements in estimating evapotranspiration accuracy, with lower errors compared to traditional methods, suggesting a refined approach using dual crop coefficients for better water management in drought conditions.

Due to the importance and complexity of water resources regulations in the pond irrigation systems of the Jiang-Huai hilly regions, a water allocation simulation model for pond irrigation districts based on system simulation theory was developed in this study. To maximize agricultural irrigation benefits while guaranteeing rural domestic water demand, an optimal water resources regulation model for pond irrigation districts and a simulation-based optimal water resources regulation technology system for the pond irrigation system were developed. Using this system, it was determined that the suitable pond coverage rate (pond capacity per unit area) was 2.
