Announcements: InfoWorks RS and ZOOM Linked to Model Oxford

Title

InfoWorks RS and ZOOM Linked to Model Oxford 

Body

HR Wallingford has recently undertaken a joint research project with the British geological Survey (BGS) to explore the benefits of using OpenMI (Open Modelling Interface) technology for linking existing surface water and groundwater models in order to develop an improved understanding of groundwater flooding processes. OpenMI technology has been used for linking an existing Infoworks RS river flow model of Oxford with an existing groundwater model (ZOOM). The main objectives of this project were to deliver:
  • An increased understanding of the benefits/difficulties of using OpenMI technology for undertaking integrated modelling studies, focusing particularly on surface water/groundwater interactions.
  • An assessment of the benefits of integrated modelling versus undertaking separate surface water and groundwater modelling studies with a focus on groundwater flooding issues.
  • A preliminary linked surface water/groundwater modelling system using Infoworks RS and ZOOM for Oxford which could be developed further for application in a variety of flood, water resource and environmental studies.
BGS have developed the ZOOMQ3D groundwater model of the Oxford floodplain in order to facilitate the linkage to the InfoWorksRS river model and have further developed the ZOOM code to enable handling of different spatial scales in the two models as required. HR Wallingford set up the linked model, which currently covers the northern part of Oxford with particular focus on the Port Meadow area; the OpenMI composition currently includes over 2000 links allowing exchange of river stages and flows. The integrated model has so far been tested successfully on the recent major flood event in 2007 in order to explore groundwater flooding issues. The groundwater model representation is however currently very simple and further work is required on the ZOOM model to investigate the effects of the Oxford alluvium on flood processes.

The study supports the Environment Agency's research strategy on integrated modelling and will provide new versatile modelling tools for developing an improved understanding of groundwater flooding. The tools have been applied to the Oxford catchment, but can be applied to any other location where complex surface water-groundwater interactions are of interest. The work was funded by BGS Science Budget and HR Wallingford research funds and was linked to the collaborative BGS-Environment Agency "Oxford Flooding" project managed by David MacDonald on behalf of BGS and William Chan on behalf of the Environment Agency.
