This report documents an investigation of the coastal and inlet physical processes acting at the San Bernard River mouth, Texas. The U.S. Army Engineer District, Galveston, requested the U.S. Army Engineer Research and Development Center (ERDC), Coastal and Hydraulics Laboratory (CHL), to conduct this study to assist in formulation and assessment of alternatives for improving navigation along the Gulf Intracoastal Waterway (GIWW) between the Brazos River and the San Bernard River and vicinity. In recent years, a spit has grown from northeast to southwest across the San Bernard River mouth. The migrating river mouth is narrowing, and sediment shoaling landward of it has reduced the river's discharge to the Gulf of Mexico. River flow is diverted into the GIWW, increasing the current velocity in an unpredictable way and possibly increasing sediment shoaling at the intersection of the river and the GIWW, as well as to the east at the west floodgate to the Brazos River. The present study was performed to identify and evaluate alternatives for maintaining the San Bernard River mouth. The San Bernard River is located in north-central Texas and flows through the alluvial valleys of the Colorado River and Brazos River. The central Texas coasts spans several zones from humid in the north to dry subhumid in the south. Average annual rainfall ranges from 104 to 125 cm, with large variations possible between droughts and precipitation brought by tropical storms. The San Bernard River has a much smaller drainage area than either the Colorado River or the Brazos River, with correspondingly much weaker flows and sediment discharge. Therefore, local storms primarily determine its flow. This study was organized in three components as an analysis of the coastal geomorphology and sediment-transport processes, a hydraulic analysis of the river and tidal flow, and a synthesis of results leading to development and evaluation of alternatives.

This proceedings contains nearly 200 papers on cutting-edge research presented at the seventh international Symposium on Coastal Engineering and Science of Coastal Sediment Processes, held May 26, 2011, in Miami, Florida, USA. This technical specialty conference was devoted to promoting an interdisciplinary exchange of state-of-the-art knowledge among researchers in the fields of coastal engineering, geology, oceanography, and related disciplines, with a theme of bringing together theory and practice. Focusing on the physical aspects of sediment processes in various coastal environments, this three-volume conference proceedings provides findings from the latest research and newest engineering applications. Session topics cover a wide range including barrier-island morphodynamics and evolution, beach nourishment and shore protection, coastal dunes, cohesive sediment transport, field and laboratory measurements of sediment transport processes and numerical modeling, gravel transport, large-scale and long-term coastal changes, LiDAR and remote sensing, longshore and cross-shore sediment transport, marsh and wetlands, regional sediment management, river deltas, sea-level changes, shelf and sand bodies, shoreline changes, tidal inlets and navigation channels. A special session on recent research findings at the Northern Gulf of Mexico is also included.

This book draws together a series of studies of spit geomorphology and temporal evolution from around the world. The volume offers some unique insights into how these landforms are examined scientifically and how we as humans impact them, offering a global perspective on spit genesis and evolution. Spits are unique natural environments whose evolution is linked to the adjacent coast and near shore morphology, sediment supply, coastal dynamics and sea-level change. Over the past century, Global Mean Sea Level (GMSL) has risen by 10 to 20 centimetres and many coastal spits represent the first sentinel against coastal submersion. Scientific research indicates that sea levels worldwide have been rising at a rate of 3.5 millimetres per year since the early 1990s, roughly twice the average speed of the preceding 80 years. This trend, linked to global warming will undoubtedly cause major changes in spit morphology. Spits are highly mobile coastal landforms that respond rapidly to environmental change. They therefore represent a signature of past environmental change and provide a landform indicator of climate change.

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.
