After successfully implementing InSAR mapping in the Houston-Galveston region in 2019, this new project will harness the complimentary capabilities of the Subsidence Districts subsidence monitoring network and SAR imagery to develop these historical deformation maps. region since the early 1900s. feet of subsidence had occurred in the Houston-Galveston region.

Though subsidence rates are moderate in Fort Bend county, the continued heavy dependence of groundwater use may result in increased subsidence and associated impacts such as flooding and infrastructure damage.

Regional water-level change maps were constructed by interpreting the compiled water-level altitude data Data were compiled and multiple hydrologic parameters were utilized to improve the understanding of the brackish resources within the study area. According to the Harris-Galveston Subsidence District (HGSD), land subsidence is the sinking of the earth's surface due to subsurface (underground) movements.

Subsidence Lone Star Groundwater Conservation District 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. Science and Research - Fort Bend Subsidence District (FBSD) - Fort Bend Working with surface water suppliers the HGSD controls subsidence by managing the use of groundwater resources in Harris and Galveston Counties. The District was created to provide for the regulation of groundwater withdrawal. <> The District uses exceptional scientific research to ensure the best available technology and approaches are considered with respect to water management and subsidence monitoring.
