Water Resources Engineering
SR 3006 over York Run, Fayette County
FE provides a growing variety of services in the area of Water Resources Engineering, including the following software programs:
- HEC-RAS with RAS Mapper
- Watershed Modeling System (WMS)
- HY-8 for culvert hydraulics
- EFH 2 (Engineering Field Handbook Chapter 2) for hydrologic analysis
- TR-55 for watershed hydrology
- National Streamflow Statistics (NSS)
- National Flood Frequency (NFF)
- PSU-IV
- Storm Water Management Model (SWMM)
- MicroStation/OpenRoads
We have a particular interest in Sustainable Drainage and Watershed Management. This includes developing ideas to promote infiltration, reduce runoff quantity and pollution, and treat stormwater as a resource instead of a waste product.
