Hydrology and Hydraulics Reports Available
The Coirib go Cósta Flood Relief Scheme Hydrology and Hydraulics Reports have been made publicly available and are available to view on the project website.
Hydrology Report
The scope of the Hydrological Study includes:
- Review of the hydrological analysis undertaken for the Western CFRAM Study;
- Review of the available records of historic flooding in the study area in order to inform the selection of design flows;
- Tidal flood frequency analysis;
- Review of data recordings of River Corrib Gauges;
- Estimate of flood flows and hydrograph shapes at key locations in the study area for the design flood events using a range of methodologies including the Flood Studies Report, Flood Studies Update etc.;
- Production of a hydrology report which presents the key findings of the study

Hydraulics Report
The scope of the Hydraulics Study includes:
- Review of the hydraulic modelling undertaken as part of the Western CFRAM Study;
- Development of a dynamic 1D/2D hydraulic model of all the relevant watercourses and associated floodplains within the scheme area;
- Calibration of the hydraulic model against historic flood events;
- Underake a wave overtopping assessment and analysis;
- Simulation of a range of combined fluvial/tidal design flood events for the current scenario for both fluvially dominant and tidally dominant scenarios. The Annual Exceedance Probability (AEP) events considered are: 50%, 20%, 10%, 5%, 2%, 1%, 0.5% and 0.1%. Ground water flood risk and Pluvial flood risk were also assessed as part of the project;
- Production of flood maps for Galway which integrate fluvial, tidal and pluvial flooding for both the existing and climate change scenario;
- Production of a hydraulics report which presents the key findings of the study
