Flooding can occur in a number of ways, and each may be affected by climate change. Surface water flooding occurs where heavy rainfall can’t absorb into the ground or drain away. Developments can worsen this situation by reducing the permeable area in an area, making it more difficult for surface water to drain away.
It is therefore important to be able to predict the flow of surface water, how the movement of surface water will be changed by a development site, how it interacts with soil conditions and groundwater, as well as how it will react in extreme weather events.
We can, from a topographic survey and an analysis of ground and groundwater conditions, produce a model of surface water flow, identifying where there is a risk of flooding on a site and detail mitigation methods for resolving these problems.
