Title: Catastrophic flooding and distributional patterns of Pacific cordgrass ("Spartina foliosa" Trin.).
Author: Zedler Joy B.
Citation: "Bulletin of the Southern California Academy of Sciences," 85(2):74-86, 1986.
Year: 86

Abstract: The distribution of Pacific cordgrass ("Spartina foliosa") is patchy within the southern California region, within particular wetlands and within clones. Small-scale patchiness cannot be fully explained by environmental variables. However, study of cordgrass before and after catastrophic flooding has led to an alternative model. It is proposed that establishment is most likely after fresh water dilutes soil salinities and that expansion and persistence depend on previous densities, disturbances, and competitors. Soil salinity is reduced with episodic flooding, at which time cordgrass can establish seedlings and invade suitable habitats. Clones spread more rapidly after flooding. Cordgrass is establishment-limited, and historical events exert substantial control over its distribution and abundance.

Title: Effects of levee extension on marsh flooding.
Author: Wang Flora Chu
Citation: "Journal of Water Resources Planning and Management," 113(2):161-176, March 1987.
Year: 87

Abstract: Western Terrebonne Parish, a low-lying coastal marsh with numerous meandering bayous and small lakes, is located in south-central Louisiana. An extension of the existing Avoca Island levee is proposed for further providing flood protection to the area. This paper evaluates the potential changes in the hydrologic regime and the area's hydrodynamics caused by the proposed levee extension. The study area is modeled as a network of junctions and channels. Riverine and tidal boundary conditions are used as input to a watershed model that predicts the time history of water level, flow, and sediment of the area. The response of the marsh to flooding events is simulated with both existing and future conditions. The results in terms of surface water contours, current discharge patterns, and sediment concentration distributions are presented. The changes before and after the levee extension are discussed.

Title: A review of conditions associated with high sea levels in southern California.
Author: Flick Reinhard E.
Citation: "The Science of the Total Environment," 55:251-259, 1986.
Year: 86

Abstract: Southern California is often considered immune from the catastrophic flooding that periodically inundates the Atlantic and Gulf coasts of the U.S. The generally mild weather and relatively sheltered coast supports this popular conception. However a series of severe winters (1977-78 and 1979-80) and the El Niño winter of 1982-83 have shaken the idea that this highly developed region is beyond threat. This report briefly reviews the large-scale and short-term conditions that lead to anomalously high sea levels in southern California.

Title: Changes occurring along a rapidly submerging coastal area: Louisiana, USA.
Author:
Salinas L. M.;DeLaune R. D.; Patrick W. H. Jr.
Citation: "Journal of Coastal Research," 2(3):269-284, Summer 1986.
Year: 86

Abstract: Within the last century the Louisiana coastline began an accelerated rate of retreat primarily due to rapid subsidence. Implications of changes occurring along the rapidly subsiding Louisiana coast could be of concern worldwide, because similar situations may be encountered if the predicted global rise in sea level occurs. Coastal subsidence causes numerous habitat changes. Various human and natural processes conjunctively influence the rate of deterioration. Landward retreat of the wetlands, in addition to causing land loss, promotes secondary effects such as saltwater intrusion, aquifer contamination, loss of freshwater marshes and disappearance of the present biota. Flooding will cause increases in salinity, waterlogging, and anaerobiosis, killing native vegetation and eventually resulting in open bodies of water.

Abstract: The Federal Emergency Management Agency has recently made available a very flexible storm surge model to simulate surges caused by hurricanes. Inputs to the model include bathymetry, coastline configuration, boundary conditions, bottom friction and other flow resistance coefficients, surface wind stress, and atmospheric pressure distribution. Non-standard features of the model include imbedded sub-grid features such as barrier islands, roadways and channels, wind stress reduction over vegetated land, depth variable Manning coefficient and a nonlinear combination of surge and astronomical tide. The model has been modified and used to simulate flooding in coastal Louisiana. This paper demonstrates the use of the surge simulations to define flood protection options for engineers and managers.

Title: Foreseeable flooding and death of coastal wetland forests.
Author: DeLaune R. D.; Patrick W. H.; Pezeshki S. R.
Citation: "Environmental Conservation," 14(2):129-133, Summer 1987.
Year: 87

Abstract: With the prediction of future rises in sea level, coastal vegetation is expected to be subjected to increasing degrees of inundation. This paper examines the relationships between sedimentation, submergence, and seedling survival in the Lake Verret watershed located in the Mississippi River deltaic plain. Vegetation types here range from bald cypress and tupelogum in the wetter areas to bottomland hardwood in the drier areas which are located on natural ridges. Portions are flooded for extensive periods of the year.

Title: Rising water levels in coastal Louisiana: implications for two coastal forested wetland areas in Louisiana.
Author: Conner William H.; Day John W. Jr.
Citation: "Journal of Coastal Research," 4(4):589-596, Fall 1988.
Year: 88
Program#: LSU-CEI-87-09

Abstract: In recent papers, the impact of sea level rise on coastal marshes has been detailed. Very little attention, however, has been placed on the impact rising water levels might have on the more inland coastal forests. In Louisiana, water levels are rising rapidly, and it has been suggested that this will affect seedling survival. This paper is designed to determine the historical trend in flooding patterns in two Louisiana forested coastal watersheds. Apparent water level rise is greater than sedimentation, leading to vertical accretion deficits; this deficit is cumulative and is leading to a significant increase in the number of days flooded per year in each basin. If present trends continue, the wetlands forests in these basins will eventually be continually flooded and unable to reproduce themselves.

Title: Hurricane-induced sediment deposition in a Gulf coast marsh.
Author: Rejmanek Marcel; Sasser Charles E.; Peterson Gary W.
Citation: "Estuarine, Coastal and Shelf Science," 27:217-222, 1988.
Year: 88

Abstract: Rates of sediment accumulation in four coastal marsh communities in the Mississippi River deltaic plain, Louisiana, were studied using feldspar clay marker horizons. The results indicate that normal riverine flooding contributes relatively little (0.1 cm/yr) to marsh accretion in the studied area. In contrast, even a minor hurricane can resuspend sediments from shallow bays and deposit more than 2.2 cm of sediments in "Phragmites australis"-dominated communities adjacent to the bayous as far as 7 km inland from the bay shore. Hurricane-induced sedimentation represents at least a partial compensation for prevailing subsidence of marshes in abandoned delta lobes.

Title: Global change and freshwater ecosystems.
Author: Carpenter Stephen R.; Fisher Stuart G.; Grimm Nancy B.; Kitchell James F.
Citation: "Annual Review of Ecology and Systematics," 23:119-139, 1992.
Year: 92
# Pages: 21

Abstract: This review addresses the potential effects of global climate change on lake and stream ecosystems. Concern for brevity severely constrained the topics covered. This review is limited to fishes, which interact strongly with lower trophic levels, illustrate key considerations common to other aquatic organisms, and are significant to the public. Although wetlands interact intimately with streams and lakes, consideration is limited to their interactions with atmospheric chemistry. The review is organized around two broad scales of change. Transitional scales pertain to landscape-level shifts in location, morphometry, and persistence of lakes and streams and their biotas over decades to centuries. Perturbational scales pertain to events with return times of years to decades that affect entire stream or lake ecosystems, such as floods, droughts, or fish recruitment events. Ecosystem metabolism as an integrated response to climate, and feedbacks between freshwaters and regional climate, are addressed, as are uncertainties that should influence future research priorities.
