    "description": "The Geoscience Team have set up a project to review the groundwater level data we hold from\nacross our groundwater monitoring network (130 sites). We have chosen 40 site to look at in\nmore detail using the modelling code the British Geological Survey (BGS) have developed to\nget a standard groundwater index (SGI).\nThe aim of the project is to use the AquiMod 2 groundwater model (Mackay et al. 2022) in\nconjunction with historical, bias corrected climate data to reconstruct daily groundwater level time series back to 1894 at each borehole, before calculating an equivalent standardised time\nseries which can be used to assess the historical occurrence of groundwater drought at each\nborehole.\nOnce the data is processed through the modelling code, we (NRW in house) can then use this\ndata to compare and review groundwater levels from sites with different geologies and\ngeographical areas from around Wales in a standardised way. This allows analysis of drought\nresponse and allow us to consider drought management in the future.\nThe BGS have developed the modelling code to determine the SGI. They are the only\norganisation within the UK that can use the modelling code as the code is not commercially\navailable. As the BGS are the only organisation we must follow the Single Tender Action\nprocurement process to secure a contact for the works.",
