Hydrology and Hydraulics

Hydrology and Hydraulics

As hydrologic and hydraulic engineers, we have extensive experience in hydrologic investigations, bridge hydraulics, geomorphology, stable channel design, scour computations, countermeasures, flood plain analysis, and permitting. UB Consulting Engineer Ltd’s work for roads has taken us all over Uganda.

Field reconnaissance and data collection is a critical part of hydrologic and hydraulic efforts, which identifies potential problems at bridge sites or other areas that require drainage analysis and design. Our staff routinely addresses concerns regarding flooding, stream stability, maintenance, and environmental impacts.
