Description: A resiliency study was conducted by the USACE to propose projects that mitigate heavy shoaling, GIWW-T shoreline and barrier island erosion, and address sea level rise that all impact safe and reliable navigation on the GIWW-T. The study evaluates various alternatives for different segments of the GIWW-T to address these concerns and improve resilience.

Description: The Caney Creek and Sargent Beach region of the GIWW-T experiences extensive impacts from riverine, tidal, and over wash shoaling mechanisms. Barge draft limitations occur frequently in this area leading to navigational hazards and economic losses. USACE ERDC has conducted alternative analyses and modeling to identify mitigation measures for shoaling at Caney Creek, and the GIWW Resiliency Study contains information on proposed mitigation projects for this region.

Description: The Brazos River flood locks are the most challenging component of the GIWW-T and need immediate replacement. The structure's narrow width, poor alignment, and frequent maintenance result in long delays, dangerous navigation conditions, and negative economic impacts on barge operators and clients. The USACE developed a Feasibility and Environmental Impact Assessment for replacing the Brazos River Floodgates.

Description: The Corkscrew Bridge in Sargent, Texas, is notable for its innovative spiral design, which was an effective solution to navigate a constrained site with limited space. The bridge employs a helical or corkscrew-like curvature to provide a stable and efficient crossing over the GIWW while minimizing the need for extensive supports and earthworks. This design demonstrates engineering ingenuity in optimizing structural integrity and spatial constraints, allowing for a functional yet visually distinctive bridge.

Description: TxDOT's point layer of general seaport locations in the state of Texas. Locations are based on aerial imagery.Texas Gulf Coast ports handled more than 563 million tons of foreign and domestic cargo in 2015 — approximately 22 percent of all U.S. port tonnage. Texas ports generate $368.7 billion in economic activity in the state and $6.9 billion in state and local taxes per year, according to the Texas Ports Association. Seven Texas ports rank in the top 50 of all U.S. ports in terms of annual tonnage, according to the U.S. Army Corps of Engineers, including Houston (2nd), Beaumont (5th), Corpus Christi (6th) and Texas City (15th). The Port of Galveston ranked as the fourth-largest U.S. cruise market based on embarkation, with more than 834,000 passengers in 2015.The use of Texas waterways is forecast to continue to increase — fueled by the expansion of the Panama Canal, the surge in the state's population and more worldwide waterborne trade.

Description: Coastal floodgates and water locks in Texas are critical infrastructures designed to manage and control water flow, mitigate flooding, and protect coastal areas from storm surges and high tides. Flood gates, often installed along rivers, estuaries, and coastal barriers, can be closed to prevent seawater from inundating inland areas during severe weather events or high tides. Water locks, on the other hand, facilitate the passage of vessels between different water levels, such as in navigation channels and ports, while also allowing for the regulation of water levels and flow. Together, these structures play a vital role in safeguarding communities, infrastructure, and ecosystems from the impacts of coastal and riverine flooding.

Description: Navigation channels are vital waterways that facilitate the safe and efficient movement of ships to and from ports by providing a navigable path through potentially hazardous or shallow areas. In Texas, these channels connect major ports such as Houston, Corpus Christi, and Galveston to international shipping lanes and inland transportation networks. Well-maintained channels, including the Houston Ship Channel and the Corpus Christi Ship Channel, are crucial for handling large volumes of cargo and ensuring smooth maritime commerce, significantly impacting both regional and national economies. This data set should not be used for navigational purposes. This data set is only meant to be used as an illustration to water passages and ship channels.

Description: The Marine Highways dataset was created on June 15, 2016 and was updated on June 04, 2024 by the U.S. Maritime Administration (MARAD) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). MARAD's Marine Highway Program is a Maritime Administration led program to expand the use of our Nation's navigable waterways to relieve landside congestion, reduce air emissions, and generate other public benefits by increasing the efficiency of the surface transportation system. This dataset contains the locations of maritime routes that connect to the Gulf of Mexico GIWW. The routes have been designated as Marine Highways by the Secretary of U.S. DOT. Routes included in this dataset are diagrammatic and may not depict all waterways and port connectors that are considered to be part of the U.S. Marine Highway System.

Description: The Coast Guard Sectors are delineated in the description in the Title 33 Code of Federal Regulations (CFR) for each Sector Boundary and Area of Responsibility where latitude and longitude coordinates, as well as county/state/national boundaries are included to describe the boundaries for each zone. In addition, whenever the Area of Responsibility boundary is over water, the EEZ shapefile is referenced for those occurrences. This layer displays the Coast Guard Sector Boundaries for the following sectors: Corpus Christi and Houston - Galveston.
