Book Description
Detailed systematic surveying of the beach and nearshore environments of two areas in southeastern Lake Michigan permits analysis of changes in morphology with respect to monitored environmental variables. Eighteen variables were measured at 2-hour intervals during a 30-day time series study. Morphologic responses and sedimentary processes can be related to these variables. Construction of a model of sedimentation in the nearshore environment is made possible by daily maps and time-distance diagrams. This provides a four-dimensional dynamic model which is a response model to the measured environmental variables. (Author).

Book Description
A monitoring program to evaluate the effects of beach nourishment material placed on a cohesive shoreline in southeast Lake Michigan was conducted at St. Joseph, MI, by the U.S. Army Engineer Waterways Experiment Station. In conjunction with this monitoring program, this particular study focuses on a 6-km (3.7-mile) section of shoreline extending southward from the jetties of St. Joseph Harbor. Some of the geological variables that affect cohesive shores were investigated. The primary objective of the study was to develop an improved understanding of the relationship between the movement of the cohesionless sediment (both fine and coarse grain components) and the irreversible downcutting of the underlying glacial till at the St. Joseph project site. Data collected during the monitoring program were input into a 2-D numerical model to describe the cross-shore sediment process and to predict the profile response to storm conditions with the influence of the underlying glacial till represented as an erosion-resistant sublayer. The 2-D profile change tests were performed at 10 of the profile locations.

Book Description
Richard A. Davis The zone where land and sea meet is composed of a variety of complex environ ments. The coastal areas of the world contain a large percentage of its population and are therefore of extreme economic importance. Industrial, residential, and recreational developments, as well as large urban complexes, occupy much of the coastal margin of most highly developed countries. Undoubtedly future expan sion in many undeveloped maritime countries will also be concentrated on coastal areas. Accompanying our occupation of coasts in this age of technology is a dependence on coastal environments for transportation, food, water, defense, and recreation. In order to utilize the coastal zone to its capacity, and yet not plunder its resources, we must have extensive knowledge of the complex environ ments contained along the coasts. The many environments within the coastal zone include bays, estuaries, deltas, marshes, dunes, and beaches. A tremendously broad range of conditions is represented by these environments. Salinity may range from essentially fresh water in estuaries, such as along the east coast of the United States, to extreme hypersaline lagoons, such as Laguna Madre in Texas. Coastal environments may be in excess of a hundred meters deep (fjords) or may extend several meters above sea level in the form of dunes. Some coastal environments are well protected and are not subjected to high physical energy except for occasional storms, whereas beaches and tidal inlets are continuously modified by waves and currents.

Suspended sediments collected on 4 different days in 1979 have been ,easured with a Quantimet image analyzer and identified by particle type. The data may be used to deduce changes in particle composition as a function of particle size, season of the year, and water depth
