Surface / Groundwater Hydrology

Gaston Engineering & Surveying, P.C. offers a variety of hydrologic and hydraulic related services. Using software such as HEC-RAS, WaterCAD, StormCAD, AutoCAD and HY-8, we can model and generate results for many types of projects. Examples of past projects are:

• Using base flood elevations (BFE’s) to model river and stream flows for determining and mapping the floodplain
• Modeling water flows in pipes for determining flowrates and pressures in domestic and fire lines
• Calculating runoff from watersheds
• Routing watershed runoff through ponds and reservoirs
• Water storage tank sizing and design
• Booster station design
• Pump sizing and design
• Embankment stabilization and erosion control
• Determining groundwater flow direction
• Wetland mapping
• Weir design and measurement
• Culvert sizing
