流域水环境模拟系统(DWR)及其应用模式

Introduction and Application Mode of DigitalWater Simulation River(DWR)

流域水环境模拟系统(DigitalWater Simulation River,DWR)是基于DigitalWater模拟平台开发的可视化建模与地表水动态模拟管理工具,通过将GIS技术和流域水环境数值模拟技术深度融合,实现对河流、湖泊、水库和河口等地表水域从空间一维到三维水动力、热量交换、物质输送(包括盐度和示踪剂)、水质、水生态、泥沙和有毒物质等过程的模拟。该系统可有效支持用户开展地表水环境影响预测评价、估算水环境容量、评估建设项目污染源排放影响、确定水环境保护范围、计算生态补水流量等方面工作,为我国流域水环境综合管控提供本地化工具。从软件功能、特点与优势、应用模式三方面,对DWR系统进行了详细介绍。

DigitalWater Simulation River(DWR)is a management tool for visual modeling and surface water dynamic simulation based on DigitalWater simulation platform.Through the deep integration of GIS technology and numerical simulation technology of watershed water environment,the simulation of hydrodynamics from one-dimension to three-dimensional,heat exchange,mass transport(including salinity and tracer),water quality,water ecology,sediment and toxic in surface waters such as rivers,lakes,reservoirs and estuaries can be realized.This system can support users to effectively predict and evaluate the environmental impact of surface water,estimate the water environmental capacity,evaluate the emission impact of pollution source of construction projects,determine the scope of water environmental protection,and calculate ecological flow,etc.It provides a localized tool for the comprehensive management of watershed water environment in China.This paper provides a detailed introduction to the DWR system from three aspects:software function,system characteristics and advantages,and applicationmodes.
