Conventional Measurement Method, Borehole Extensometers, GPS, and Measuring Subsidence in the Future. 5 0 obj Water demands were projected . By Vanessa Holt. This study, spawned from their original research that showed subsidence in southern Montgomery County was caused by exploitation of the Jasper aquifer, will investigate the combined effects of climate changes on coastal subsidence to enhance understanding of the deformation process. Phone: 281-342-3273 Groundwater Conservation District and, most recently, Brazoria County Groundwater Conservation District Evaluation of Projected Population and Water Demands in Fort Bend County. The Subsidence District has adopted regulations requiring reduction of groundwater withdrawals through conversion to alternate source water (e.g., surface water) in certain areas within the Subsidence Districts jurisdiction, including the land within Harris County MUD 501. Annual subsidence report shows Katy, Jersey Village with - impact Since 1977, the USGS Texas Water Science Gulf Coast Program has published regional groundwater maps for From USGS well monitoring over decades they are able to show that once subsidence districts are created, groundwater levels rise significantly, thereby decreasing subsidence issues in their districts. In this chapter: (1)AA"Agricultural crop": (A)AAmeans food or fiber commodities that are grown for resale or commercial purposes and that are to be used for food, clothing, or animal feed; and The Harris-Galveston Subsidence District, created in 1975, was the first of these districts. (3) "District" means the Harris-Galveston Subsidence District. their jurisdiction. HGSD Financial Information including Budgets, Annual Audits, and Financial Reports. For almost 50 years, they have been collecting, storing, and sharing data on groundwater abstraction and resulting surface lowering. Subsidence Risk Assessment and Regulatory Considerations for the Brackish Jasper Aquifer. This site is a publicly available, searchable, online database of water information. The District has taken a reasonable approach to groundwater regulation in order to minimize subsidence within its regulatory areas. Since 1990, the Fort Bend Subsidence District has regulated groundwater withdrawals and monitored subsidence in Fort Bend county. This model will provide valuable information to inform the regulatory decision-making of the HGSD and FBSD. Interpolated modeled water-level altitude surfaces were only used to compute differences when wells were Numerous subsurface faults have been documented beneath the Houston metropolitan area at depths of 3,200 to 13,000 feet. When we pump large amounts of water from the aquifers beneath us, we pull water out of the many layers of clay, which causes the clay to compact, lowering the elevation of the land above. Harris-Galveston Subsidence District reposted this, Mitigation of human-induced land subsidence starts with the regulation of resource extractions. below the land surface due to groundwater withdrawals. The USGS has a long history of working with HGSD and other entities in the Houston region. 1976 Pressefoto Charles "Chuck" R. Bowcock, Harris-Galveston These efforts have identified and documented the susceptibility of land surface subsidence due to the production of groundwater in the Chicot and Evangeline aquifers. Brazoria County Groundwater Conservation District, Lone Star Groundwater Conservation District. Working with surface water suppliers the HGSD controls subsidence by managing the use of groundwater resources in Harris and Galveston Counties. Deputy General Manager Fort Bend Operations, Now Hiring! Overview of the Harris-Galveston Subsidence District planning process. The District was created to provide for the regulation of groundwater withdrawal. Click here for more information about the Authority. The water-level measurements in the dataset are built upon and stored in the National Water Information System: web interface, groundwater information, and field measurements website located here: http://dx.doi.org/10.5066/F7P55KJN. Harris-Galveston Subsidence District and West Harris County Regional Creation year: 1975 (64th Texas Legislature). HGSD lies within the boundaries of Groundwater Management Area 14 (GMA 14). Subsidence Lone Star Groundwater Conservation District Extensometers and Subsidence. In order to evaluate the performance of the projection methodology which informed the 2013 DRP, the short-term projections from the RGUP have been evaluated against recent estimates of population and water demand from multiple sources at various geographic scales. 1985: Divided into 8 regulatory areas by amount of groundwater reduction needed. 1 of 11. Legislature authorized the establishment of the Harris-Galveston Subsidence District to regulate and the U.S. Geological Survey Texas Water Science Center Gulf Coast Program collects, processes, and Subsequent to establishing the Harris-Galveston Subsidence District, the Texas State Legislature 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. Significant brackish groundwater resources exist within the Gulf Coast Aquifer System near Houston, Texas in Harris, Galveston, Fort Bend, and surrounding counties. For detailed information on the processing methodology, please refer to https://ascelibrary.org/doi/10.1061/%28ASCE%29SU.1943-5428.0000399. endstream endobj startxref Managing how groundwater resources are used is key to controlling subsidence. Finally, use the Tab key to toggle the links within each districts. Based on this analysis, recommendations have been developed to refine the methodology used in the next regional update project to further improve the next iteration of the regulatory plan. <> Learn about the history of the Harris-Galveston Subsidence District. Over the last century, aquifers in this area have lost between 300 and 400 feet, leaving some of the land to collapse. In 2021, kriging, a geostatistical interpolation method, was Explore Groundwater-Level and Compaction Data in the Chicot, Evangeline and Jasper Aquifers. Land subsidence is sinking of the land surface, caused by compressing the many layers of clay beneath the surface. Newsroom - Harris County, Texas endobj Chicot-Evangeline (undifferentiated) and Jasper, which are composed of laterally discontinuous deposits Click here for more information about the Subsidence District. Providing analysis of accurate and up to date predictions on water usage; the enforcement of real disincentives to those who rely too heavily on groundwater; and an unwavering commitment to practicing and promoting water conservation. While some areas in Houston have significantly reduced their groundwater pumping (particularly with the creation of subsidence and groundwater districts, whose purpose is to regulate groundwater pumping), subsidence still remains a threat for the region. =*-SRIbI -|tdAl` Q ka+dzLp[fAh/tGp7=>>q[y,Nz Ma Harris-Galveston Subsidence District Permitting Portal Fort Bend Subsidence District Permitting Portal Please use one of these links to reach to the appropriate Permitting Portal. The purpose of this report is to summarize the results of the Regional Groundwater Update Project (RGUP). These sites are being cooperatively run and operated by the following agencies.
