Harris-Galveston Subsidence Districts main mechanism of regulation is through its regulatory plan, with requirements laid out in the districts enabling legislation. 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. Southeast Texas Groundwater Conservation District; Other Districts. This effort has published aquifer levels and subsidence data since 1975 and is a great example of what can be accomplished through sustained collaboration between, city, county, regional, and federal partners. It is the purpose of the HGSD Regulatory Plan to establish policy in the area of groundwater regulation, permits and enforcement. Some natural land subsidence also occurs over long periods of time, due to natural settling. The nearby hydrograph shows that when a subsidence district was created around 1976 (red line), groundwater levels in the Chicot Aquifer rose substantially. compaction data. In the Houston-Galveston region, land subsidence is caused by compaction of fine-grained aquifer sediments (silts and clays) below the land surface due to groundwater withdrawals. %PDF-1.3 In fact, the USGS serves as the hub for an annual multi-agency data collection effort that includes the Brazoria County GCD, Lone Star GCD, the City of Houston, and both subsidence districts. The development of brackish groundwater resources has become a more common water management strategy in the State of Texas. These efforts have identified and documented the susceptibility of land surface subsidence due to the production of groundwater in the Chicot and Evangeline aquifers. as the difference in water-level altitude at each well for the water-level data collection year and the Created by the Texas Legislature in 1975 to stop further subsidence in the Houston-Galveston region. HGSD Financial Information including Budgets, Annual Audits, and Financial Reports. Next, we traveled to the infamous Brownwood Subdivision, which was abandoned due to substantial subsidence in the 1980s.
