Hydrology, Civil Engineering - Water Resources, Hydraulics, Floodplain, Flood Forensics, Hydrologist, Hydraulic Modeling, Transportation Drainage, Roadway Drainage, Rainfall, Runoff, Design Storms, Sedimentation, Sediment Transport, Stormwater, Culvert, Stormsewer, Urban Hydrology, Urban Flooding, Construction

Water flows downhill, sometimes water is a resource, sometimes it is an enemy, sometimes it is both. If your case involves the impact of water, my expertise is available for your case. I am an expert in hydrology, hydraulics, the engineering of drainage systems, including culverts, transportation drainage, bridge scour, bridge hydraulics, floodplain management, transportation hydraulics, water resources, and accidental death or drowning near hydraulic structures. My work routinely produces technical evidence that is hard to dispute and easy to understand. My background and experience in consulting and teaching allows me to produce complicated information in a format that is easy to digest, such as video files, and images that explain the complicated physical interactions of hydrology and hydraulics. Some of my past litigation work produced evidence that was not disputed by opposing experts. My approach is to first understand the case, then to discuss one on one what technica...
