RAA RASS RSK taglines 02

We provide constructive, practical advice on all matters within the urban drainage, flooding, and hydraulic engineering industries for legal disputes, court cases, and public inquiries. We provide specialist advice for a variety of complex 'what if' scenarios to determine both the cause and prevention of flooding incidents.

Our UAV aerial photography, film, and multispectral imaging can add context and perspective to complex legal cases.

Flooding

From this, we can design and advise on solutions that can be developed to prevent repeat flooding incidents.

Hydrology

We provide insight into significant hydrology matters around the country that is often crucial to the outcome of a case.

Hydraulic Modelling

We bring clarity to the complex reality of particular sites with our close attention to detail and practical experience in hydraulic modelling.

Claimants are unlikely to have the necessary specialist modelling information that they need. This usually means that they will either have to do their own surveys and build their own hydraulic models. The most straightforward response to this need is to employ an expert such as ourselves as both the information required and its interpretation is highly complex.
