Available in PDF, EPUB and Kindle. Book excerpt: An environmental study was conducted at Sargent Beach, Texas, an erosive beach bordering the Gulf of Mexico. The objectives of this study were to determine the characteristics of the beach, the magnitudes of changes which have occurred at Sargent Beach, and to analyze possible factors which may be controlling the observed beach changes. Results show the beach has eroded at an increasing rate since at least 1930 with recent shoreline retreat rates averaging 30 feet per year. Storms are the primary agents that remove material from the beach, while lost sediments are not replaced because Brazos River sands normally expected to move alongshore are trapped in the Brazos delta. Hurricanes may free stored deltaic sands carrying major quantities offshore from beach areas. Beach erosion is further aggravated by decreased sand input to the coast from the Brazos River due to alterations to the river and its drainage basin in the 1940's.

Available in PDF, EPUB and Kindle. Book excerpt: The constantly increasing urban and industrial demands on Texas shorelines have placed great stress on a delicately balanced environment. There are tremendous political and economic incentives for the development of methods which will predict the reaction of the coastal system to planned man-made changes on or near the coastline, This thesis examines a method for shoreline stability analysis which could be used in conjunction with conventional studies of beach erosion rates to provide a more thorough understanding of the interaction of waves, the longshore current, and the coastal sediments. A method for the prediction of erosion and deposition rates related to the interaction of longshore currents and the sediment discharged at the mouth of a river is developed, and this method is applied to the new Brazos River delta near Freeport, Texas.
Book Synopsis Variability in Rates and Styles of Shoreline Retreat Generating a Sea Cliff and Wave-cut Platform at Sargent Beach, Texas by : Rose Palermo
Download or read book Variability in Rates and Styles of Shoreline Retreat Generating a Sea Cliff and Wave-cut Platform at Sargent Beach, Texas written by Rose Palermo and published by . This book was released on 2016 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Texas mainland beaches are characterized by a mudstone substrate and an overlying mobile layer of sand. Beaches exhibiting the highest rates of shoreline retreat erode into wave-cut platform or sea cliff morphologies, dependent on elevation above sea level. This study examines the relationship between temporal and spatial variability in shoreline retreat rates and shoreline roughness at Sargent, TX and how they are jointly controlled by changes in sand cover and storm wave intensity. Retreat of the cliff face is estimated as an annual rate by calculating the difference in cliff face position from repeat aerial photographs in 2009, 2010, 2011, 2012, 2014, and 2015. These average rates are 12.391 m/yr, 7.801 m/yr, 5.719 m/yr, 4,812 m/yr, and 3.699 m/yr respectively. Local roughness of the shoreline is also calculated for these cliff face positions. Average roughness values are 3.960 m, 6.679 m, 6.129 m, 5.563 m, 1.886 m, and 2.633 m respectively. Annual retreat rate is found to decrease linearly as roughness decreases. Monthly retreat rates throughout 2015 were measured using erosion pins. Monthly erosion rates were as low as 0 - 0.054 m/month and indicate that intervals of extreme erosion are necessary to produce the retreat observed over the course of a year. Monthly surveys of the wave-cut platform positioned immediately adjacent to the sea cliff record ~5 meters of shoreline retreat in 2015, demonstrating a strong spatial variability in shoreline retreat rate. Although this spatial variability exists over short timescales, the sea cliff and wave-cut platform erode linearly on the multi-decadal scale. The results of this study demonstrate that monitoring over a range of temporal and spatial scales is crucial to understanding the patterns and process which govern shoreline retreat along the Texas Gulf Coast.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most important aspects of coastal management and planning programs that needs to be investigated is shoreline dynamics. Long-term coastal analysis uses historical data to identify the sectors along the coast where the shoreline position has changed. Among the information that can be obtained from these studies are the general trend of coasts, either advancing or retreating. The erosion or accretion rates at each location can be used to forecast future shoreline positions. The current techniques used to study shoreline evolution are generally based on transects perpendicular to a baseline at selected points. But these techniques proved to be less efficient along more complex shorelines, and need to be refined. A new and more reliable method, the topologically constrained transect method (TCTM), was developed for this study and tested using data available for three sectors of the Texas Gulf Coast. Output data generated from TCTM also allowed performing shoreline evolution analysis and forecasting based on historical positions. Using topological constrained transects, this study provides a new method to estimate total areas of accretion or erosion at each segment of the coastline. Reliable estimates of future gains or losses of land along the coast will be extremely useful for planning and management decisions, especially those related to infrastructure and environmental impacts, and in the development of coastal models. Especially important is the potential to quickly identify areas of significant change, which eliminates the need for preliminary random sample surveying, and concentrate higher-resolution analyses in the most significant places. The results obtained in this research using the new methodology show that the Texas coast generally experiences erosion, with anthropogenic factors responsible for accretion. Accretion areas are located near coastal infrastructure, especially jetties that block the along shore sediment transport. The maximum erosion rate obtained in the study area is 5.48 m/year. This value helps make us aware of the powerful dynamic of the sector.
