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.
