Gerald Blackler, Ph.D, P.E., D.WRE

Denver, Colorado
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...

Kenneth R Dees, P.E.

Storm Water Engineering Senior Technical Authority

CM2E

Fort Worth, Texas
Civil Engineering, Hydrology - floodplain, detention pond, drainage failures, downstream impact, flooding claims, FEMA, hydrology, hydraulics, diversion of storm waters, rivers, creeks, bridges, culverts, site plans, subdivision development, stormwater design, site development, flooding claims, regulatory compliance, forensice engineering
Kenneth Dees, P.E. CFM has over 40 years of experience in the water resources industry and is a senior technical authority regarding storm water, drainage and floodplain engineering. A graduate of Southern Methodist University (1984), he is a business owner, project manager and civil engineer who has been involved in some of the largest projects in the history of the State of Texas. He has considerable expertise pertaining to topics related to storm water engineering of all types. After graduation from SMU, Mr. Dees began his career at MCI Telecommunications where he was responsible for tracking all construction projects on a nationwide scale and reporting to the chief engineer for this multi-billion dollar company. During this time, he made a discovery of how to connect maps to data which greatly expanded the capability to manage infrastructure of all types. This discovery lead to creation of a software company a short three years after college, which would morph into Chalk Mo...
