Break-out Group Discussion on Recharge
2nd Annual Española Basin Workshop
March 5, 2003
Notes prepared by
Amy Lewis, Jemez Y Sangre Regional Water Planning Group
Summary of Comments
Back to Past Workshops and Meetings
- Seepage studies which quantify the amount of water either discharging from the aquifer or recharging the aquifer are vital to understanding the flow components in a basin.
- Because estimating recharge in every mountain front is very difficult, estimating discharge to stream, springs and wells (combined with the change in storage) provide a better method of estimating recharge.
- Measure discharge at La Cienega and other springs in the region
- Increase the number of streamflow gages in the basin.
- Be cautious using flow data due to great uncertainty in stream flow measurements
- Use InSar and microgravity techniques to measure land surface deformation
- Use water quality analysis to identify recharge zones. Isotopes and general chemistry provide information about the conceptual mechanisms for recharge and for quantifying recharge.
