This week iCASP hosted a workshop for a range of organisations across Yorkshire involved with flood preparedness and response, and national organisations responsible for producing flood forecasts and alerts. The workshop was run to test out how useful it could be to combine probabilistic rainfall forecasts (Met Office Global and Regional Ensemble Prediction System, MOGREPS) with high-resolution hydrodynamic modelling (JBA’s JFlow®) to provide localised surface water flood forecasts.
A mock incident response situation – Exercise Augustus – was run using JBA’s Exercise Management System (JEMS), which presented representatives from Yorkshire’s Local Authorities, flood action group leaders, Environment Agency, emergency services and Yorkshire Water with the ‘new’ forecasts based on a real flooding incident in Leeds to see how they responded to the information they were given, and what decisions and actions they would take as a result.
This kind of incident response scenario planning gives us an understanding of the kinds of information that incident responders find most useful in helping them make their decisions – both in advance of an incident and also as the incident is unfolding.
The participants worked in four groups so that their thoughts on the information they were presented with, and the rationale for their decision-making, could be understood and captured. A report will be produced summarising the different responses of the groups that will allow iCASP partners to better understand the ways to present information to flood responders, and which kinds of information elicit the most appropriate responses to the situation.
The flood that Exercise Augustus was modelled on took place in Garforth, Leeds on August 22 2015.
