Aquifer Storage and Recovery

ASR is the storage of water in a subsurface aquifer during times of water surplus, which can be used at later times when water is less available. ASR has become a successfu water management tool in arid environments as well as many coastal regions. However, there are numerous difficulties associated with understanding the spatially exhaustive changes in water quality through time as well as processes that may plug the aquifer (changes in porosity, entrapped gas, biogeochemical changes) due to geologic heterogeneity and data sparsity.

We are currently starting a new project studying ASR processes with a goal to image 3-D changes in water quality through time using geophysical methods. We're working on developing intelligent survey design and "informed" inversion for crosswell electrical methods to produce quantitatively meaningful tomograms.
