Project Description

Malachy Walsh and Partners were commissioned to carry out a detailed flood risk assessment including developing a hydraulic model of the 3000m of the Curraheen River Reach. The purpose of this was to assess whether a viable new Science and Innovation Park could be developed without affecting the river flows upstream and downstream of the development. This required the assessment of a site with a total area of 126ha with 6 no. existing bride/culvert structures. The brief included carrying out bridge location assessments and Section 50 applications for 2 no. new bridge crossings. The outline SuDs requirement for the development was also assessed and is to be incorporated into the Masterplan for the development.


FSR and FEH techniques were examined in conjunction with continuous flow records at the site to derive unit hydrographs and design flows for critical storm durations. He prepared a hydraulic model of 3000m of the Curraheen River reach and 600m of the Twopot River. The Study concluded that the CSIP could be developed by incorporating an amenity lake and overflow weir in the development as part of the mitigation measures since parts of the proposed development were located within a floodplain.
