This book represents the efforts of over a hundred individuals who planned and executed the NSTS field experiments, analyzed the billions of data points, and distilled their findings and insights into the summaries found here. Because these experiments were of a scope that will seldom, if ever, be duplicated, and because the program brought together many of the foremost field experimentalists in this country, we all felt from the beginning that it was important to preserve the outcome. This was done in two ways. First, the raw data were made available to any interested investigator within 18 months of the completion of each experiment. Secondly, both the methodology of the experiments and the findings from them were codified in the form of a monograph. This book is that result. I have had the occasion recently (Sediments '87 Proceedings, Vol. 1, pp. 642-651) to assess the NSTS performance. I found that we made giant strides in our understanding of the surf zone hydrodynamics --far more than our fondest expectations at the beginning. We were able to do less than we had hoped about the response of the sediment, largely because of a limited ability to measure it at a point. As I reported in the Sediments '87 assessment, we established a new state of the art in measurement techniques and we demonstrated the effectiveness of large, multi-investigator, instrument-intensive experiments for studying nearshore processes.

The purpose of this book is to give an introduction to the most important aspects of suspended matter in the aquatic environment: its origin and composition, the concentration distribution, transport and deposition, and the most important physical-chemical-bio logical process that affects suspended matter: flocculation. In Chap ter 1 the development of suspended matter observation and study throughout history is given, with the coming of a more modern approach during the 19th century and the first half of the 20th century, and the development of the present science of suspended matter after 1945. The sources of suspended matter in rivers, lakes, estuaries, and the sea are discussed in Chapter 2, which includes the supply of detrital particles as well as the formation of new particles in the water (organic matter, carbonate, opal). The concentration distribution of suspended matter in rivers, lakes, estuaries, tidal is discussed in Chapter 3, to which is areas, lagoons, and in the sea added a discussion on the sampling of suspended matter and on methods to determine its concentration. Particle composition is treated in Chapter 4, to which is added a section (4. 6) on the compositional analysis of suspended particles. Also included is a discussion on particle surface characteristics and the adsorption of elements and compounds onto particles.

Developments in Geotechnical Engineering, 23: Stability of Tidal Inlets: Theory and Engineering focuses on all aspects related to tidal inlets on littoral drift shores where freshwater flow is small or non-existing. The selection first tackles the development and configuration of tidal inlets and inlet hydraulics. Discussions focus on flow dynamics and nearshore transport, combinations of waves and currents, sediment transport and storage in the tidal entrance, offsets of tidal inlets, natural inlet regimen, migration of inlets, and origin of tidal inlets. The manuscript then examines sediment transport in tidal inlets, stability of tidal inlets on littoral drift shores, and design and improvements of coastal inlets. Topics cover ocean entrance, overall stability condition, hydraulic and sedimentary principles, non-scouring channels, transport of sediments in wave agitated waters, and sediment transport by combined wave and current action. The publication explores improvements by structures, including natural bypassing, types of improvement, and bypassing by structures and bypassing plants or arrangements. The selection is a valuable source of data for researchers interested in the stability of tidal inlets.
