About Morton-Roberts


Morton-Roberts is a firm of civil engineering consulting engineers based in Cardiff. We serve the South Wales, Bristol, Bath, Swindon, Cheltenham, Gloucester and Hereford area although for expert witness work we cover the whole of England and Wales.

We specialise in the investigation, analysis and design of drainage, land drainage and sewerage systems. Please see below for further details.

Drainage Design Services

Our main areas of work are as follows:

•  Drainage for New Developments. Preliminary and detail design

of drainage for new 'green' and 'brown' field developments including both foul and surface water systems. We are also able design surface water drainage systems using SUDS (Sustainable Drainage Systems) techniques for a wide range of situations.

•  Expert Witness Services. We are able to offer the services of one of

our senior staff as an expert witness in the sewerage and drainage area of civil engineering.

•  Flood Risk Assessments and Flood Consequence Assessments.

We are able to undertake the preparation of Flood Risk Assessments (for use in England) or Flood Consequence Assessments (for use in Wales).

•  Hydrology including the estimation of river flows using Flood

Estimation Handbook methods.

•   1D River Modelling and 2D Flood Modelling. We use either ISIS 1D

or HEC-RAS software to carry out 1D hydraulic river modelling work and ISIS 2D software for 2D flood modelling.

A complete list of all our areas of work is given on our home page.

Our Software

To enable us to carry out the types of work outlined above we have an extensive range of drainage design and analysis software which is summarised on our Drainage Design and Analysis Software page and also listed below.

•  FEH (Flood Estimation Handbook)
•  Micro Drainage:  Source Control,
    System 1 and Simulation modules
•  ISIS 1D and HEC-RAS River Modelling
•  ISIS 2D Flood Modelling
•  AutoCAD Civil 3D
