BRACS studies
BRACS studies can be conducted in-house by BRACS staff or externally by a consulting firm under contract with TWDB and staff member managing the contract. A study typically consists of:
- evaluating publically available water well records, geophysical well logs, and geologic reports,
- entering information into the BRACS Database,
- comparing top, bottom, and lateral extent of water-bearing geologic formations,
- interpolating data points from BRACS Database to build new formation structures,
- mapping the water-bearing portions of the aquifer and their hydraulic properties,
- estimating salinity from water well records and geophysical well logs,
- estimating volumes of brackish groundwater,
- preparing geographic information system files, and
- writing a report summarizing findings.
