Introduction
Hydro Survey, working with AECOM on behalf of Northern Ireland Water, carried out a detailed geophysical survey of the River Foyle in Derry in September 2021. The aim was to get a clear picture of the riverbed and the ground beneath it to inform the design and building of a new wastewater pipeline.

What we delivered
To achieve this, Hydro Survey employed a range of advanced techniques, including multibeam echosounders, side-scan sonar, magnetometers, shallow single-channel seismics, and ultra-high-resolution seismics. The latter, in particular, was crucial in providing detailed insights into the subsurface conditions, enabling the project team to assess potential risks and plan the pipeline route effectively.
Hydro Survey processed and analysed the data, producing detailed reports and high-resolution images.

We engaged Terra Survey to undertake an extensive geophysical survey of existing flood defences predominantly to the west of Limerick City. We were particularly interested in understanding the depths of any soft soils and the potential presence of karstic features in the bedrock. Terra Survey reviewed our proposed survey and advised on tweaks to optimise the survey to ensure we gathered all of the required information. Terra Survey’s site team undertook the survey promptly in very challenging terrain. The report produced by Terra Survey on completion of the fieldworks was to a very high standard. We were delighted with Terra Surveys inputs to the project and we look forward to working with them again in the near future.
