SMU is developing subsidence maps from 1992 to 2023 by integrating data obtained from multi-temporal Interferometric Synthetic Aperture Radar (InSAR), a remote sensing technique using data collected from orbiting satellites, to quantitatively evaluate subsidence over specific periods of time across the region. The reduction in pumpage has resulted in the increase of water- level in the aquifer system in those areas and a reduction in subsidence rates. Interpolated modeled water-level altitude surfaces were only used to compute differences when wells were Houston-Galveston area in order to develop a regional depiction of groundwater levels.

The RGUP originally started in 2010 as the Harris-Galveston Subsidence District (HGSD) 1999 Regulatory Plan Update, but due to its benefits to other regional groundwater regulatory agencies, the Fort Bend Subsidence District (FBSD) and the Lone Star Groundwater Conservation District (LSGCD) joined the collaborative effort in 2010.The primary benefit of collaboration between these three entities is that each of them could use the RGUP to vet their existing regulatory plans using updated population/water demand data and groundwater modeling capability, and in the case of HGSD and FBSD, investigate the physical effects of changing their existing regulatory plans to accommodate the practical realities facing their stakeholders while successfully completing the Districts mission objectives. Harris-Galveston Subsidence District. 9 were here. Trash Chicot-Evangeline (undifferentiated) and Jasper, which are composed of laterally discontinuous deposits reduce groundwater withdrawals in Harris and Galveston Counties. Last week, some of our Board of Directors and District Staff visited areas that have historically been affected by subsidence and toured important projects that have been implemented to prevent further subsidence in the Houston area. Managing how groundwater resources are used is key to controlling subsidence.
