The Authoritys GRP sets forth the Authoritys plan to comply with the Subsidence District regulations, construct surface water facilities, and convert users from groundwater to alternate source water (e.g., surface water). This study provides a basis for future research on subsidence in the Districts area and can inform water managers and planners in the Houston area on the availability of brackish groundwater resources. <> UNESCO Land Subsidence International Initiative. In 2001, the Texas legislature created the West Harris County Regional Water Authority (the Authority) to, among other things, reduce groundwater usage in, and to provide surface water to, the western portion of Harris County and a small portion of Fort Bend County. The Houston area's two subsidence districts the Harris-Galveston Subsidence District, HGSD, and the Fort Bend Subsidence District have worked to monitor subsidence and mitigate it through a variety of water management efforts.

A focus of these scenarios will be on the variables that minimize subsidence in the future while accounting for the availability of alternative water supplies. However, there is another cause of subsidence in our area which causes the activation of surface faults (which can damage roads, houses, and buildings), loss of wetlands and . The GULF-2023 model is a new $588,000 endeavor jointly funded by the HGSD and FBSD, in cooperation with USGS.

In cooperation with Legislature authorized the establishment of the Harris-Galveston Subsidence District to regulate and Regular, precise, automated readings are taken of the elevation of the ground at locations throughout the county. 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. Now on its fifth iteration since 1976, the plan describes the different regulatory areas throughout the district, defines groundwater withdrawal limits for each area, and provides guidelines for permitting. the Houston-Galveston Region, Texas. The Authority has developed a groundwater reduction plan (GRP) and obtained Subsidence District approval of its GRP. Significant brackish groundwater resources exist within the Gulf Coast Aquifer System near Houston, Texas in Harris, Galveston, Fort Bend, and surrounding counties.
