Abstract

The coastal geomorphological processes of alongshore transport and tidal currents are interacting with the attendant influences of sea-level rise and sediment supply to generate morphosedimentary units in selected estuarine systems. Constrained by the conditions promoted by microtidal situations in barrier island settings, vectors of sediment transport have established spatial sequences of morphologies and sediment types that are components of shellfish habitats. Greater depth and decreasing grain-size toward the mainland are common characteristics in five northeastern U.S. estuarine systems. The patterns are repeated at various scales among the lagoon-type estuaries as well as within the estuarine settings to establish geospatial associations of geomorphology and habitat., Background The basic concept of an estuary is that it is an aquatic system located at the land-sea interface, and it is a transition feature, extending from freshwater to marine [...]

Abstract

Foredune Crestline displacements have been investigated through aerial photographic interpretation during the period 1976-1986. Although the mean condition is a slow inland displacement, 0.33 m/yr, many geomorphological variations exist in a spatial matrix. A 9-year foredune/beach profile monitoring program on Fire Island, 1982-1991, produces data on the dimensional changes of the foredune. A complex pattern of annual variation in addition to alongshore variation emerges that links beach budgets directly to dune budgets, and scarping processes to dune budgets. Sand fences do not uniformly create sand accumulation on the profile. Sand fence accumulations are on the order of 1-2 m²/yr. Erosion events cause an order of magnitude greater removal from the dune portion of the profiles. Two major storms provide most of the erosion in the 9-year period., Consacrée à Fire Island, île-barrière à l’est de New York, cetle étude porte sur les différentes méthodes utilisées pour la gestion des dunes côtières. Celles-ci peuvent être aussi bien loties que préservées dans le cadre de Parcs ; les secteurs sauvages alternent ainsi avec les secteurs bâtis. Les dunes bordières constituent un enjeu essentiel pour la protection côtière puisqu’elles fixent vers la mer une zone entièrement inconstructible : le maintien de la dune est donc vital et toutes les méthodes douces sont utilisées. Un suivi sur 10 années montrent le succès relatif des opérations de protection qui n’empêchent évidemment pas l’érosion. Les auteurs montrent d’ailleurs que, pour efficaces que soient les mesures prises, le sort de la dune est : d’abord lié au transit littoral qui fournit aux plages la substance des engraissements de la dune. Si, sur le long terme, le succès paraît évident, l’occurence de sévères tempêtes balance parfois en peu de temps les résultats obtenus., Psuty Norbert P., Piccola Tammy A.

39. A tribute to Roland Paskoff (1933-2005): Friend and colleague

Author

Psuty, Norbert P., Zazo, Caridad, Psuty, Norbert P., and Zazo, Caridad

Abstract

The world of coastal geomorphology lost a very active and exceptional scientist with the passing of Roland Paskoff (Fig. 1) in September 2005. He left this world as he participated in it, after being in the field with students. Roland was a friend and advisor to many of us and his presence will be missed in the field and at the numerous international venues in which he participated.

Abstract

Spatial variations in sedimentation during individual tidal cycles were investigated using filter paper traps. The mean mass of sediment deposited in each tidal cycle was higher at the levee edge than at the inner marsh. The mass of sediment decreased with distance from the head of the estuary. There were weak relationships between tidal regime and sediment accumulation. Spatial variations of annual accretion rates were investigated with marker plots. The annual accretion rate at the inner marsh was higher (1.5 to 3.5 cm/y) than that at the tidal river levee edge (0.8 to 3.0 cm/y). Total suspended sediment (TSS) concentrations in the tidal water column indicated that the accretion rate was affected by vegetation. TSS concentrations in the water column leaving the vegetation cover during ebb tidal flows dramatically decreased. There were strong relationships between the concentration of suspended load and accretion rate. The spatial pattern of sedimentation processes at different timescales was mostly due to erosion of the levee edge by tidal flow. The major findings are: (1) The spatial patterns of sedimentation processes at various timescales are different, (2) vertical accretion rates ranged from 0.9 cm/y to 3.5 cm/y, (3) the study area has a depositional regime over the timescale of the present data, (4) the mean and minimum deposition rates in the study area are higher than other cited systems, and (5) the high accretion rate of this area is related to human-induced environmental change, and the sedimentation trajectory is now evolving to a new equilibrium.

Abstract

Beach nourishment was applied at three fetch-restricted sites along the estuarine margin of Delaware Bay, New Jersey. Evaluation of geomorphological performance of the nourishment project was conducted through seasonal monitoring to track linear features (shoreline, dune crest, peat edge) and to create digital elevation models (DEMs). Comparisons of the DEMs yielded sediment budgets of the updrift, fill area, and downdrift zones as well as the spatial and temporal evolution of the tidal flat, beach, and dune features within the zones. Through four years, Moore's Beach lost all of the emplaced fill as well as an additional −5446 m3 from the fill area. The shoreline position shifted inland −12.78 m, and the foredune crest shifted inland −9.23 m. The fill area at Pierce's Point lost all of the fill and an additional −3810 m3. The shoreline and dune crest shifted inland −7.35 m and −1.17 m, respectively. The Reed's Beach study area benefited from beach fill updrift that more than offset the losses in the fill area, a net gain of 2107 m3. There was a major contrast in volumetric change between the updrift and downdrift portions. Sediment budget calculations established alongshore transport was an important factor in the fetch-restricted estuarine environment driving the variable geomorphological responses in the updrift, fill, and downdrift zones.

48. THE TABASCO LOWLANDS OF SOUTHEASTERN MEXICO.

Author

Abstract

The Tabasco lowlands form Mexico's largest alluvial coastal plain. Bordering the southernmost part of the Gulf of Mexico, these lowlands are hot and wet. They afford a laboratory in which to examine physical processes and living conditions within a humid tropical coastal environment. Geologically, the lowlands are composed of two distinct surfaces: (1) the Recent alluvial plain, made up of river deltas, flood plains, and beach deposits; and (2), farther inland, the Pleistocene alluvial surface of highly weathered stream-deposited sediments. The morphology of the Recent alluvial plain is a product of Mexico's two most voluminous rivers, the Grijalva-Mezcalapa and the Usumacinta. Several tropical vegetation formations, each with its particular faunal assemblage, once covered the Tabasco lowlands. Before its alteration by man a dense rain forest was the most extensive formation, followed in size by freshwater marsh in interlevee depressions. Despite a seemingly unfavorable environment, the Tabasco deltaic plain was well populated in pre-Columbian times, as evidenced by archeology and early Spanish accounts. After 400 years of demographic and economic decline, the lowlands have only recently regained population densities and economic importance comparable to those before the Conquest. (Author)

49. THE GEOMORPHOLOGY OF BEACH RIDGES IN TABASCO, MEXICO.

Abstract

The largest coastal alluvial-plain in Mexico lies along the southern Gulf Coast, almost entirely within the state of Tabasco. This plain is principally of fluvial origin, associated with the Mezcalapa and Usumacinta river systems. These two rivers, whose previous channel migrations have directly or indirectly produced most of the lowland landforms, currently share the major outlet to the Gulf, the Grijalva River. Skirting the gulfward edge of the Tabasco Plain is a narrow zone of coastal landforms comprised primarily of beach ridges plus a few groups of sand dunes. Systematic investigation of beach ridges includes profiles noting general configuration and dimension. Beaches are profiled to record sediment removal, migration, and accumulation over various time periods. Trenches and pits dug in accretionary portions of the beach profile reveal stratification sequences of inland-dipping foreset units. These deposits correlate with frequent winter-season storms, nortes, which raise Gulf levels and wave heights to construct a beach crest upon the winter beach. Intermittent washover deposition contributes sediment to the upper surface and lee side of the ridge to heighten and broaden it while producing a slow migration inland. Subsequent calm-weather accretion gradually widens the beach and eventually strands the beach ridge. Beach ridges are most numerous and the coastal zone widest where river channels course through the coastal topography and discharge into the Gulf. Adjacent to these channels, the ridge trends collectively arch seaward, fan-like, to produce a cuspate delta projecting into the Gulf. (Author)

Abstract

A specialized bibliography, arbitrarily limited to 1000 entries, was assembled as a part of the background preparation for a long-range research program studying marine desert ecology, particularly as it occurs along the central coast of Peru. The ecology of this coast of Peru is more complicated than usual because the unusual foggy desert environment is a reflection of some remarkable near-shore conditions. This listing was prepared solely to serve certain needs of the investigators engaged in this marine desert ecology project, and should not be considered absolutely exhaustive in any of the component subject disciplines.
