WMS | 水文模拟处理软件

WMS (Watershed Modeling System)专业的水文模拟处理软件 ,提供水文模拟全过程的工具,包括流域、子流域的自动生成、几何参数的计算、水文参数 (如汇流时间、降雨深等 )的计算等 ,并能实现模拟结果的可视化。WMS可以使用矢量地图、DEM、TIN等格式的数据来进行地形分析和水文模拟。嵌入了多种传统的概念性水文模型 ,包括 HEC- 1、NFF、TR-20、TR- 55、Rational Method、HSPF等 ,根据自动提取的流域参数进行水文模拟 ,可以用于洪水预报、水库设计、城市规划等。

 

The All-in-one Watershed Solution

WMS is a complete watershed solution used for automated delineation, hydrologic & hydraulic modeling, floodplain mapping, and storm drain modeling.

 

The complete all-in-one watershed solution

■GIS Tools

■Web-based data acquisition tools

■Terrain data import and editing tools

■Automated watershed delineation & hydrologic modeling

■Support for the most industry standard hydrologic models

■Step-by-step hydrologic modeling wizard

 

 

Automated watershed delineation & hydrologic modeling

■Automatically delineate a watershed and sub-basins using digital terrain data

■Automatically compute geometric basin data such as area, slope, mean elevation, maximum flow distance and more

■With a small amount of input, compute hydrologic basin data such as time of concentration, curve number, and infiltration parameters

■Industry standard equations for computing sub-basin lag times and times of concentration are included with WMS

■Add any number of interior outlet points and let WMS subdivide the watershed automatically

■Manipulate stream networks to represent man-made features or proposed changes to the watershed

■Override derived basin boundaries to match your knowledge of the watershed

 



Support for most industry standard hydrologic models

■A license of WMS Hydrology or greater includes an interface for the following industry standard hydrologic models:

■HEC-1

■HEC-HMS

■TR-20

■TR-55

■Rational Method

■MODRAT

■OC (Orange County, California) Rational

■OC Hydrographic

■HSPF

■National Streamflow Statistics

■Convert and compare the results of a watershed developed for one model with any of the other models supported in WMS

■Read and compare observed hydrographs with computed hydrographs

 



Hydraulic modeling & floodplain mapping

■Define a stream centerline and bank stations

■Define cross section locations

■Automatically cut cross sections and derive Manning's roughness values from elevation and ground material data

■Export cross sections to the HEC-RAS or Simplified Dam Break hydraulic models

■Run the hydraulic model and read the water elevations back into WMS

■Read water surface elevation data from a hydraulic model or manually input known water surface elevations

■Create flood extents and flood depth maps using digital terrain data and water surface elevation data points

■Link the peak flow or complete hydrograph from any of the WMS-supported hydrologic f

 



Storm drain modeling

■Draw a storm drain network or import a network from GIS

■Compute elevations, lengths, and slopes of pipes from underlying elevation data

■Link the storm drain network to your hydrologic model data

■Export the hydrologic model data and the storm drain network to EPA-SWMM or XP-SWMM

■Import existing EPA-SWMM or XP-SWMM files into WMS

 



2D (Distributed) hydrology

■WMS supports 2D models:

■The US Army Corps of Engineers (USACE) GSSHA model

■The HMS version of the quasi-distributed MODClark method

■Flood forecasting (depth and velocity over entire 2D domain)

■Thunderstorm (localized rainfall) flood analysis

■Surface ponding and infiltration analysis

■Wetland modeling

■Land use change impact modeling

■Groundwater/surface-water interaction modeling

■Sediment and contaminant modeling

 



Import what you need

■USGS DEMs - download and use any format of DEM from the USGS

■USGS NED data - seamless elevation data can be downloaded and read into WMS

■ArcGIS Raster (ASCII format) - read elevation or attribute data in gridded format from ArcGIS

■ESRI Shape files - read all shapes and attributes into WMS

■DXF and DWG CAD files - WMS now supports the latest versions of DXF and DWG

■TIFF, JPEG image files - /images along with geo-referencing information can be read by WMS

■Any data supported by ArcGIS can be read into WMS (ArcGIS license required, compatible with ArcGIS 10.0)

 



Software from an Industry Leader

WMS is developed by Aquaveo, an engineering services company with many years of experience developing watershed modeling solutions.

■Step-by-step tutorials and how-to videos

■Online community forum and product documentation

■Phone and email technical support

■Regularly scheduled training courses taught by expert modelers

■On-site training available

■Professional consulting services

 

WMS 9.1 System Requirements

Microsoft® Windows® XP

■RAM: 512 MB (2GB Recommended)

Windows Vista®, Windows 7 or Windows 8

■RAM: 1 GB (4GB Recommended)

■CPU: GMS software is CPU intensive. Some models and utilities integrated with WMS can take advantage of multiple processor cores simultaneously.

■Graphics Card: For all display features to be enabled, OpenGL 1.5 or higher must be supported. The use of a dedicated graphics card is strongly recommended. Integrated graphics can result in significantly reduced performance and may not support some visualization features.

■Display Resolution: 1024 x 768 or greater
