The data are the gridded recharge values obtained from the BGS distributed recharge model (ZOODRM) driven by 11 Ensembles of the HaDCM3 Regional Climate Model (RCM) taken from the Future Flow and Groundwater Level data set (http://www.ceh.ac.uk/our-science/projects/future-flows-and-groundwater-levels). The model covers the mainland areas of England, Scotland and Wales. The 11 ensembles are run from January 1950 to December 2099. The dataset themselves are the gridded (2 km by 2 km) outputs from the recharge model averaged over four time horizons: historical, 20s, 50s, and 80s, for each of the 11 ensembles. The results can be used to assess the impact of climate change on potential recharge (soil drainage) for catchments in mainland England, Scotland and Wales.
These files include hydrochemical data and groundwater level time series for a number of boreholes and wells within the basement aquifers of the Romwe catchment. For each borehole/well there are associated depth, geology and use data. A time series study of abstraction was also carried out for a subset of wells. Time series rainfall data for a rain gauge in the catchment is also included. These data were collected through a series of projects: Small scale irrigation using collector wells: pilot project (CEH/BGS/Zimbabwe Ministry of Lands, Agriculture and Water Development; DfID funded) Sustainability of yield from wells and boreholes in hard rock aquifers (BGS; DfID funded) Regional groundwater recharge assessment in semi-arid areas (CEH/BGS; DfID-funded) The Hydrology of a dry land catchment in southern Zimbabwe, and the effects of climatic and land use change on shallow groundwater resources (PhD project, Uni. Reading/CEH) Integrated Catchment Management and Sustainable Water Resource Development in Semi-arid Zimbabwe (PhD project, Uni. Reading/CEH) Note: CEH (Center of Ecology and Hydrology) was known as ‘IH’ during the period of the study

The data sets contain the monthly rainfall volume from manual rain gauge stations spread across the study area. There are 11 rainfall stations. The rain unit is mm. In addition, the dataset contains the chloride concentration in mg/l of the rainfall, for each month. Blank data (-) means data not available due to not enough rain volume, no rainfall or problems when transporting the samples from Kenya to Barcelona. The data available is only from April 2016 to November 2017. This data is useful to calculate the recharge volume by chloride mass balance (CMB) methodology. https://www.hydrol-earth-syst-sci-discuss.net/11/307/2014/hessd-11-307-2014-print.pdf
