USACE CWMS - Chena River Watershed

The Corps Water Management System (CWMS) includes four interrelated models to assist with water management for the basin:

- GeoHMS (Geospatial Hydrologic Modeling Extension)
- ResSIM (Reservoir System Simulation)
- RAS (River Analysis System)
- FIA (Flood Impact Analysis)

The District currently utilizes a SSARR model for routing flow through the basin. This model will be utilized as a calibration tool during the development of the CWMS model

军团水资源管理系统（CWMS）集成了四个相互关联的模型，旨在协助流域水资源管理：
- 地理水文模型扩展（GeoHMS，Geospatial Hydrologic Modeling Extension）
- 蓄水池系统仿真（ResSIM，Reservoir System Simulation）
- 河流分析系统（RAS，River Analysis System）
- 洪水影响分析（FIA，Flood Impact Analysis）
该区目前使用SSARR模型来调度流域内的水流。该模型将作为校准工具，在开发CWMS模型过程中得到应用。
