We have developed a variety of in-house hydrologic models
computer models to harness information concerning parameters such
as rainfall, to augment knowledge of surface runoff patterns for
both water resources studies and flood studies. These are
supp-lemented by the use of proprietary software wherever
this is appropriate.
Water resource assessment
Modelling work carried out for water resource assessment activities
includes development of models for arid catchments where stream
flow is dominated by groundwater contributions, use of soil water
balance based models for ungauged catchments, as well as
development and use of the Stanford watershed model and HYSIM
modelling system. Hydrological resource models have been linked to
groundwater models for a number of projects in the past, providing
a comprehensive and complete catchment model.
Flood studies
Hydrologic modelling for flood studies usually use simpler models
such as the US Soil Conservation Service method to determine flood
hydrographs. The techniques we use differ between urban and rural
catchments, and depend on the quantity and quality of calibration
data available. We have used complex models successfully on many
projects in both environments where problem complexity and data
availability have needed such approaches.
