摘要
针对沿海中小河流域地表-地下水库复杂工程系统,因缺少联合调控方法而导致洪水资源利用难的问题,解析地表-地下水库系统结构与功能,定量模拟地表水库调度、闸坝调控下河流和地下水动力过程,并利用智能替代模型提升水动力过程计算速度;在此基础上通过研发时/日/月多时间尺度模型耦合嵌套方法,构建了兼顾计算精度与效率的地表-地下水库联合调控模型.该模型实现了洪水、地表-地下水相互作用和供水等时间尺度差异明显的调节过程的统一调配,可为沿海中小河流域洪水资源利用提供新思路与技术支撑.
Abstract
In response to the lack of joint regulation methodsof the complex engineering system of surface-underground reservoirs in coastal small and medium-sized river basins,which leading to difficulties in flood resources utilization,the structure and function of surface-groundwater reservoir system was analyzed,the surface reservoir regulation and dynamic processes of rivers and groundwater under gate dam regulation were quantitatively simulated,and the intelligent replacement models to improve the calculation speed of hydrodynamic processes were used.A multi-time scale model coupling nesting method of hour/day/month was developed to construct a joint regulation model of surface-underground reservoirs that takes into account calculation accuracy and optimization efficiency.This model realized the unified allocation of floods,surface groundwater interactions,and water supply,which can provide new ideas and technical support for the utilization of floodwater resources in coastal small and medium-sized river basins.
