## Summary

The procurement process is being conducted by the Defra Network eTendering Portal for the project titled "Test and Itchen Groundwater Model Update Phase 2", classified under design-modelling services. The procurement is at the tender stage, with an open procedure method below threshold. Key dates include the tender period closing on 17th September 2018, with the contract expected to begin on 12th November 2018 and end on 2nd December 2019. The procurement is situated in the South East region of England, and the contract value amounts to £120,000.

This tender presents significant opportunities for businesses specialising in design and modelling services, particularly those capable of updating and maintaining sophisticated groundwater models. Small and medium-sized enterprises (SMEs) are encouraged to participate, especially those with expertise in MODFLOW modelling techniques. Firms with capabilities in data processing and environmental consulting will be well-suited to compete for this contract, which aims to enhance essential groundwater management tools.

## Notice

The current Test and Itchen groundwater model comprises a groundwater flow model (MODFLOW-96-VKD) and a separate runoff-recharge model (Routing of Rainfall to Runoff and Recharge (4R)). The model was built in 2005 and has been updated a few times during its lifetime. The main aim of this project is to maintain an up to date tool, using the best techniques and data. In order to do this, we would expect the consultant to: reconceptualise and update the conceptualisation since the original development of the model, update the model data to current date, and update/rebuild the model in MODFLOW6 code. A number of scenarios will need to be run, and data will be need to be presented back to the EA. A key part of the project is updating the model to MODFLOW6 code; this is a fairly new code and therefore there won't be a wealth of pre and post processing tools available.
