Title

Groundwater level logger data for 7 wells , Kwale County, Kenya (NERC grant NE/M008894/1)

Abstract

The data sets contain the daily record of meters of groundwater columns for 7 Heron logger transducers installed in different boreholes and wells in the study area. Missing data denoted -9999. The Barlog data for atmospheric pressure (Atmospheric Pressure data measured by Heron Barologger for the period of April 2014 to November 2018 at Munje Jabalini.) is also included. "Uncomp.HT.WTR. Above Transducer" corresponds to the actual pressure the dipperLog is measuring. "Barologger Data" corresponds to the Barlog data for atmospheric pressure at Munje Jabalini "Comp.Depth.WTR Below the Datum" is the "Depth below datum" entered in the logger setup less "Comp.HT.WTR. Above Transducer". The data was collected by Albert Folch and Nuria Ferrer (UPC), Mike Lane and Calvince Wara (Rural Focus Ltd). The PI on the Gro for GooD project was Prof. Rob Hope, University of Oxford.

Quality and validity

Lineage

Seven wells/boreholes were carefully selected in order to install a logger sensor (Heron logger transducer) to provide a continuous measure of groundwater level. The sites were selected according to the location in the study area, the security of the waterpoint, the geology, the aquifer unit (in this case all the logger are installed in the shallow aquifer< than 50-meter depth). First, the loggers were programmed to take a measurement every 15 minutes and then re-programmed to take a measurement every hour. Before installing the sensor, the groundwater level was measured with a dipper and the sensor was then installed below the groundwater level depth in order to avoid that the sensor remained submerged. It was necessary to download data before the logger memory was full, and then re-program again to continue measuring.
