FREE - Round 1 - Modelling groundwater flood risk in the Chalk aquifer from future extreme rainfall events Project


* Introduction

Recent events have shown that groundwater flooding is a serious risk to property, infrastructure and social disruption, and is a particular problem for the Chalk of South East England. The nature of this risk is poorly understood, and there is no adequate methodology to assess it.

This proposal integrates state-of-the-art models of the soil, unsaturated zone, groundwater and surface water to provide a new modelling tool for risk assessment, and also investigates the use of simpler models for warning of the potential onset of flooding and regional assessment of risk.

Experimental data from the NERC Lowland Catchment Research Thematic Programme (LOCAR) and historical data from affected areas will be used to test hypotheses and develop and validate the models. The models will be run for future climate states to assess current and future risk using an ensemble of climate models.

Project Duration: April 2007 - April 2010.

This project is funded by NERC - Grant Ref. NE/E002307/1 - through the Flood Risk for Etreme Events (FREE) NERC directed mode programme.

* Availability of data

This project will develop and integrate existing soil, unsaturated zone, groundwater and surface water models, thus producing new tools for flood risk assessment. This project is building on work done for the NERC Lowland Catchment Research Thematic Programme (LOCAR), and will use data from the LOCAR archive which is based at the British Geological Survey (BGS). Any additional data collected will be added to the LOCAR archive as this is not within the remit of this project.

It will also use data collected by BGS and Brighton University but this is by private arrangement and will not be archived as part of this project. The aim of the project is to develop models and modelling tools and as such there are no specific data deliverables. However, output from notable model runs such as runs used in publications or using climate change scenarios will be archived at the NERC Centre of Ecology and Hydrology (CEH).

The data and metadata from this project will be stored at the NERC Centre of Ecology and Hydrology (CEH). A copy of the metadata will be stored at the BADC.

* Access to data and information

Data and metadata from this project will be stored at CEH, BODC and BADC as appropriate.

A copy of the metadata will be stored in the BADC FREE Modelling groundwater flood risk project archive.

Access to FREE data held at the BADC will be restricted to the FREE participants during a restricted access period ending two years after the end date of each project. Data will be made publicly accessible after that date.

If you are a FREE participant and wish to access restricted FREE data, please

* Instructions for data providers

FREE participants wishing to submit data should read the submission instructions. If you have publications arising from FREE research please send details [title, author(s), reference] to the BADC help desk for inclusion in the archive.
