Geophysics to Enhance Agricultural Productivity and Livelihoods of Smallholder Farmers through Improved Groundwater Management of the Vientiane Plain

Status: Complete

The main aim of this project was to contribute towards the hydrogeological maps’ development, and delineate good and poor quality water to lower the risk of well failure on the Vientiane Plain.

The team used near-surface geophysical techniques- Fast sampling TEM (Zonge Engineering NanoTEM system), Electrical Resistivity Tomography [ERT (IRIS Instruments Syscal Pro Switch 96)], Ground Penetrating Radar [GPR (MALA GroundExplorer HDR) and Frequency domain electromagnetic induction conductivity meters (GF Instruments CMD Explorer and Dualem EM34)]

They worked to characterize the hydrogeology at selected field sites (Phousan, Ekxang, and Viengkham districts with 18 surveys) and used this geophysical data to evaluate its utility in assessing groundwater conditions.

Honors/masters student from Flinders University, and two undergraduate/Masters students and one PhD student from the local National University of Laos were trained during this project.
