- 1. TWDB Subsidence Study January 26, 2017 TAGD Business Meeting Jordan Furnans, PhD, PE, PG Jordan.Furnans@LREWater.com (512) 736-6485 GLS Solutions, Inc.
- 2. Project Objectives • Analyze the major and minor Texas aquifers for the subsidence risk • Develop subsidence prediction tools for at-risk aquifers • Recommendation of subsidence monitoring methods
- 3. Data Compilation Three primary variables: • distribution, thickness, and compressibility of clay layers • amount and timing of water-level changes • lowest historical water level Data types we will focus on: • Geologic depositional history • Aquifer material geotechnical properties (eq clay content, compressibility) • Water-level data • Pumping data • Subsidence observations (land surface elevation changes) Clay Layer Compaction
- 4. What We’ll Be doing… • Contacting Potential Data Sources • Reviewing Data • Assessing Risk • Recommending Monitoring • State-wide Reporting
