Relay Ramp Structures And Their Influence On Groundwater Flow In The Edwards And Trinity Aquifers, Hays And Travis Counties, Central Texas, Brian B. Hunt, Brian A. Smith, Alan Andrews, Douglas Wierman, Alex S. Broun, Marcus Gary
Sinkhole Conference 2015
The Cretaceous Edwards and Middle Trinity Aquifers of central Texas are critical groundwater resources for human and ecological needs. These two major karst aquifers are stratigraphically stacked (Edwards over Trinity) and structurally juxtaposed (normal faulting) in the Balcones Fault Zone (BFZ). Studies have long recognized the importance of faulting on the development of the karstic Edwards Aquifer. However, the influence of these structures on groundwater flow is unclear as groundwater flow appears to cross some faults, but not others. This study combines structural and hydrological data to help characterize the potential influence of faults and relay ramps on groundwater flow …
