River and Stream Hydrology Studies

Hydrological assessment of river and stream reaches represents a primary activity of Hydro Environmental Ltd. In many of the projects this has involved carrying out river channel surveys, hydrometric monitoring of the water profile and flow rate and the development of numerical based 1-dimensional and 2-dimensional hydraulic models to predict channel velocity and water level throughout the subject reach and assist in the design. The variable nature of studies carried out by hydro Environmental are listed as follows:

Channel flow capacity and flow velocity Assessments
Design of weirs (inline and offline weirs), control gates and spillways
Design and capacity assessment of river bridges and stream culverts
Design of Fish Passes and fishery friendly channels and culverts
Design of low flow and flood flow channels
Design of flow diversions and flood relief schemes
Marina feasibility and impact studies
Hydrometric measurement and monitoring of flows
Dispersion and water quality assessments
Assimilative capacity Assessments
Scour and sediment deposition assessments
Storm Water Management Systems
Flood Risk Assessment Studies
