Study on karst water exploitation scheme in Huaibei City supported by external water diversion project
This study utilizes a coupled model of water level autoregression and multiple regression to establish a water level recursive equation related to exploitation volume and precipitation for the karst water system.Un-der the constraint that the groundwater level does not fall below a set level,a rational exploitation volume for karst water is designed and the exploitation strategy of karst water is discussed supported by external water di-version.Additionally,the dynamic relationship between exploitation volume and critical water level is studied.The results indicate that the water level recursive equation can be used to calculate the rational exploitation volume under the critical water level control condition.When adopting 7.5 m as the critical management water level,the exploitation intensity can be controlled at approximately 22.05 × 104 m3/d.These findings provide a reference for the formulation of future karst water exploitation schemes in Huaibei City with the support of external water diversion.
