Rhondda Valley Project

Background Information

Between July and November 2021, Storm Geomatics undertook a survey in the Rhondda Valley for Natural Resources Wales on behalf of engineering consultancy ARUP. The purpose of the project was to try and reduce the impacts of flooding after the effect events such as Storm Dennis in February 2020 had on several places within the valley. Utilising mainly Storm’s South-West office resources, six different reaches were surveyed by multiple teams with a thirty-two kilometre stretch along the River Rhondda –from Blaenrhondda all the way down to Pontypridd. In total, over 450 sections were surveyed with an additional ten kilometres of defence walls!

Their Challenge

This was a challenging survey for the team as the river conditions were often difficult to access due to the sheer size and depth of the watercourse. Due to the velocity the bed was also very smooth which again hindered ease of accessibility. However, the team drew upon their training and experience to ensure that they could collect as much data as physically possible for the client. Access into the channel was limited due to the large concrete flood defences that often lined both banks, so the surveyors had to adapt to their usual approach of setting up on the banks and often found themselves traversing up and down the channel with all their equipment.


All in all, the project was completed to a high standard with the client expressing their gratitude due to the complexity of the project. Whilst conducting the survey many valley residents expressed their opinions of the effect the river had on their lives; therefore, hopefully this data will be implemented to improve the existing defences to reduce future impacts.
