Daily handpump accelerometer data and borehole water level data, Kwale County, Kenya (NERC grant NE/M008894/1)

(I) Handpump Vibration Data For each handpump, data is organized in one CSV file per day. These files are grouped together over batches, where each batch approximately corresponds to three months. (II) Borehole Water Level Data Water level data at the borehole of each handpump is recorded in one CSV file per handpump. Both uncompensated (raw) and compensated (with respect to atmospheric pressure) data are available. (III) Data Time Logs A separate Excel file lists the locations of the monitoring sites and the time logs corresponding to both (I) and (II) per handpump. References: [1] P. Thomson, R. Hope, and T.

Statement
To test if the model generalizes to handpumps drawing water from different depths of shallow aquifer systems, three different monitoring sites are selected corresponding to three different depth ranges - shallow, medium, and deep (categories are arbitrarily defined based on available samples). (I) Handpump Vibration Vibration data is collected using a consumer grade accelerometer sensor attached to the handle of the handpump. The sensor measures accelerometry data in three orthogonal axes at a sampling frequency of 95 Hz. A typical pumping cycle, i.e. a cycle of the handle being raised and pushed down, corresponds to one second interval. (II) Borehole Water Level The water column is measured using diver sensors (manufactured by ©Van Essen Instruments or ©Heron Instruments) fixed close to the bottom of the rising main. Data is collected at a sampling interval of five-fifteen minutes.
