River and Coastal Engineering:
Our Engineers are experienced in the hydraulic and structural design of river and coastal structures such as channels, culverts, weirs and fish passes; flow controls devices; flood defence; erosion protection; and cliff and coastal slope stabilisation. We can carry out hydraulic modelling and wave overtopping calculations to determine appropriate design standards and performance. We also regularly prepare applications for statutory consents including Marine Licences, Flood Defence Consent and Abstraction Licences.
