Risk Assessment
GWP routinely provides specialist technical advice on the impact of earth and water resource exploitation and a wide range of other development activities on the water environment. We also provide related advice on avoidance or mitigation of unacceptable impacts, including design of management systems and structures. Water related risk and impact assessments include:
- the impact of de-watering on water resources and wetlands;
- the vulnerability of aquifers to land-use change;
- the impact of landfill on groundwater and surface water;
- mine water rebound effects;
- impacts on flood risk of development in flood plains; and
- pollution migration risks associated with contaminated land.
Flooding
GWP has extensive experience in flood risk assessment, management, and mitigation design. Our hydrologists have produced numerous flood risk assessments for floodplain developments at a wide range of scales, from >1 hectare developments up to the strategic catchment assessments and master-planning. This work has been undertaken in the UK and overseas, giving us experience of temperate climate, tropical and arid zone hydrology. We are able to take an integrated approach to flood risk management, for example, by examining groundwater and surface water interactions or by incorporating flood risk strategy into water resources and environmental studies.
Our analytical capabilities include:
- rainfall frequency-duration analysis;
- catchment characterisation and hydrological modelling;
- hydraulic flood flow modelling; and
- mitigation design through SUDS approaches and geotechnical solutions.
