AEC TECH NEWS: Natural Resources Wales taps CH2M’s Flood Modeller Pro for its new flood forecasting system

Denver — Natural Resources Wales, the Welsh Government’s principal adviser on issues relating to the environment and its natural resources, selected CH2M’s Flood Modeller Pro software as the core hydrodynamic modelling solution within its new flood forecasting system. The system is being built using Deltares’ Delft-FEWS software, an open data handling platform, designed for building a customized hydrological forecasting system.

“Flood forecasting is an essential component of flood risk management to reduce the impact of flood events. Early warning is crucial for efficient emergency response and contingency planning,” said CH2M Global Water Business Group President Peter Nicol. “With its short run times, model stability and ability to retain full hydrodynamic capability and extensive range of hydraulic structures, Flood Modeller Pro is extremely well-suited for flood forecasting.”

Compatible with Deltares’ Delft-FEWS software, Flood Modeller Pro is designed to rapidly and robustly perform the calculations required to predict water levels and flows as a result of rainfall and/or extreme sea levels hours or days ahead of the event. It allows the user to forecast water levels and flow rates with confidence, depending on availability of data and response time of the system. This latest award builds on an ever growing list of countries where CH2M’s industry-leading flood modelling software is being used within forecasting systems, including England, Scotland, Cambodia, Laos, Thailand and Vietnam.

Flood Risk Manager at Natural Resources Wales Andy Wall said, “We are very pleased to continue our association with CH2M’s Flood Modeller Pro software, which is used as the main tool within our real-time forecasting system for river routing and hydrodynamic modelling. The flexibility, real-time performance and resilience which this software offers are important to us in delivering a flood forecasting service in Wales, where rivers respond rapidly to extreme rainfall and where we have high risk locations where we need to model the combined effects of high river and tidal flows.”
