How to Use the Software: A Basic Workflow

While WMS is a deep program, its core workflow follows a logical, step-by-step process for watershed analysis.

Import Terrain Data: Begin by importing a Digital Elevation Model (DEM) or other terrain data into your project (File → Open). This serves as the foundation for your model.
Delineate the Watershed: Use the Terrain Data module to compute flow directions and accumulations. Then, define an outlet point on the stream network. WMS will automatically generate the upstream watershed boundary and sub-basin delineation.
Assign Hydrologic Parameters: Switch to the Map module. Use GIS tools to overlay land use and soil type maps. WMS will use these to compute key parameters like the SCS Curve Number for each sub-basin.
Build the Hydrologic Model: Go to the WMS module. Select your chosen model (e.g., HEC-HMS). You can then define rainfall events (e.g., a 100-year, 24-hour storm) using IDF curves or user-specified hyetographs.
Run the Simulation: Execute the model to generate runoff hydrographs for each sub-basin and at the main watershed outlet. The software will compute peak discharge, runoff volume, and time to peak.
Visualize and Export Results: View the resulting hydrographs graphically. For hydraulic analysis, you can export the peak flows to HEC-RAS or visualize flood extents within WMS.

Best Use Cases

Aquaveo WMS is not a one-size-fits-all tool; its strength lies in its adaptability to specific, high-stakes engineering challenges.

Urban Stormwater Master Planning: Model the impact of new developments, design regional detention facilities, and size culverts for transportation corridors under various storm events (10-yr, 25-yr, 100-yr).
Floodplain Mapping and Risk Assessment: Use FEMA-approved models like HEC-HMS and HEC-RAS within WMS to generate accurate flood boundaries for regulatory maps and risk mitigation studies.
Transportation Hydrology: Design drainage systems for highways and railways. Accurately calculate peak flows for culverts and bridges at stream crossings, ensuring infrastructure resilience.
Dam Break Analysis: Simulate the failure of a dam to generate an inflow hydrograph for downstream river modeling, helping to create emergency action plans and inundation maps.
