Geophysical Methods for exploring the Hyporheic Zone
Geophysical Methods for exploring the Hyporheic Zone
The Hyporheic Zone is an important part of the relationship between surface and groundwater and its interaction between plants, animals, and humans. Through my preliminary research, I have found that understanding the complexities of the ground under riverbeds through near-surface geophysics can give insight on the processes of water infiltration and up flow. I plan to conduct research to better understand how the subsurface affects the hyporheic zone to gain knowledge that will mitigate river water contaminant transport.
Most of my work will involve simulating models of seismic and electrical data that I will change to inverse models where values of wave travel time and electrical resistivity will be converted into observable values of wave velocity and porosity.
Below are examples of simulating a forward model of seismic data and inversion that I have previously worked on.
Simulated traveltime data with 48 geophones on a flat three layered cross section with different values of velocity
A now inverted Graph of the same travel time data run through a chi (X) statistical test to best fit the original data.
