Flood Risk Assessment
Flood risk is a key consideration for many development sites, encompassing fluvial (rivers and streams), pluvial (surface water), and coastal flooding.
We provide comprehensive Flood Risk Assessments (FRAs) for projects ranging from single properties and small developments to large-scale residential and commercial sites. Whether you require support with planning in principle, feasibility studies, masterplans, or detailed designs, our expert advice ensures cost-effective and reliable solutions tailored to your needs.
Our assessments may include fluvial, pluvial, and coastal flood risks, incorporating design flow and rainfall estimation, coastal level analysis, mathematical modelling, flood mapping, and flood management strategies.
We maintain strong relationships with local authorities and adhere to Scotland’s National Planning Framework 4, as well as council and SEPA policies and guidance. This ensures a robust and credible approach, facilitating acceptance of our findings.
Our flood risk services include:
- Site Inspections and River/Land Surveys
- Flood Flow Estimation using recognised hydrological methods, including the Statistical Method, FEH, and ReFH2
- Flood Modelling and Hydraulic Calculations using industry-standard software such as Flood Modeller and HEC-RAS, incorporating 1D and/or 2D modelling as required to meet project needs
- Flood Inundation Modelling and Mapping
- Recommendations for Flood Mitigation Measures and River Erosion Management
- Hydromorphology Assessments for River Restoration
- Liaison with Planning Authorities, Local Councils, and SEPA
- Staged Flood Risk Assessments, this approach helps minimise upfront costs for clients, if required
