Hydrogeophysical data for characterization of the Moorpark Reclamation Facility in Moorpark, CA. This facility is located along the Arroyo Las Posas River in the Little Simi Valley. The facility contains about 32 percolation ponds of which six ponds were selected to be evaluated in this study. The acquired data includes Electrical Resistivity Tomography, Electromagnetic Induction, and Guelph permeameter measurements. This data set is discussed in detail in Uhlemann et al., 3D Hydrogeophysical Characterization of Managed Aquifer Recharge Basins.

Hydrogeophysical data for characterization of the Moorpark Reclamation Facility in Moorpark, CA.

This data set includes ERT, EMI, and hydraulic conductivity measurements in support of characterizing the Moorpark Reclamation Facility, in Moorpark, CA, USA.

The data set is structured in 3 folder, with each folder representing the data acquired with each technique.

EM: Measured apparent conductivities using a CMD Mini Explorer (GF Instruments). The data has been filtered, and points within a 0.5 m radius have been averaged. No other processing has been applied. 
    Data is provided in a text file, with coordinates for each sounding. The coordinate system is NAD83 UTM Zone 3N. 
    The header provides information on the system settings. Data were acquired using a horizontal coplanar loop orientation, at 24740 Hz, at 0.2, 0.33, 0.5, 0.72, 1.03, and 1.50 m coil separation. The system was carried about 0.1 m above the ground.

ERT: Data files for each pond, i.e. POND9, POND10, POND11. 
     Each file contains the electrode arrangements with their measured transfer resistances
     Information on the electrodes location is provided at the top of the file

Permeameter: The folder includes:
	    (1) an excel sheet with the observations of the infiltration rate for each location, as well as the coordinates for each measurement
            (2) a jupyter notebook that reads the data and calculates the hydraulic conductivity from the observations
