基于Web的泥沙与侵蚀控制规划设计与决策支持系统 规范信息和指导工具)(http://www.ecn.purdue.edu/runoff/sedspec)是为预测而开发的 小流域洪峰径流和设计水文、泥沙和侵蚀控制措施。SEDSPEC系统是 由模型、数据库和用户界面组成，它们是基于模型的决策支持的典型组件 系统(DSS)。两种水文模型(Rational方法和TR-55)模拟短期洪峰径流 场地特定的水文土类和土地利用。水文模型使用存储的设计风暴数据估计峰值径流 在关联的数据库中。决策支持系统集成了WebGIS技术，帮助用户估计分水岭边界并访问 空间数据库，以获取流域的土地利用和水文土类数据。作为最终输出，SEDSPEC计算 基于用户规格的水文、泥沙和侵蚀控制结构的尺寸和成本，并提供 结构维护信息。提供了一个案例研究来演示SEDSPEC决策支持系统的使用和功能。 该系统可以成为一个有效的工具，方便决策者的设计和规划过程。
A Web-based decision support system called SEDSPEC (Sediment and Erosion Control Planning, Design and SPECification Information and Guidance Tool) (http://www.ecn.purdue.edu/runoff/sedspec) was developed for predicting small watershed peak runoff and designing hydrologic, sediment, and erosion control measures. The SEDSPEC system is comprised of a model, database, and user interface, which are typical components for a model-based Decision Support System (DSS). Two hydrologic models (the Rational Method and TR-55) simulate short-term peak runoff based on site-specific hydrologic soil groups and land uses. The hydrologic models estimate peak runoff using design storm data stored in associated databases. The DSS integrates WebGIS technology to help users estimate watershed boundaries and access a spatial database to obtain land use and hydrologic soil group data for the watershed. As the final output, SEDSPEC calculates dimensions and costs of hydrologic, sediment and erosion control structures based on users’ specifications, and provide structure maintenance information. A case study is provided to demonstrate the use and functionality of the SEDSPEC DSS. This system can be an efficient tool to facilitate a decision-maker’s design and planning procedures.
