Beach nourishment - Wikipedia, the free encyclopedia Beach nourishment is a process by which sediment (usually sand) lost through longshore drift or erosion is replaced on a beach. Beach nourishment projects are usually constructed along shorelines where an erosional trend is present that could be either natural or a result of human activities. Beach nourishment is usually but not always carried out on an eroding shoreline and is favored by a substantial upland investment and a relatively mild erosion rate. en.wikipedia.org /wiki/Beach_nourishment   (1651 words)

Beach - Wikipedia, the free encyclopedia A beach or strand is a geological formation consisting of loose rock particles such as sand, gravel, shingle, pebbles, cobble, or even shell along the shoreline of a body of water. Beaches are deposition landforms, and are the result of wave action by which waves or currents move sand or other loose sediments of which the beach is made as these particles are held in suspension. Beach nourishment is common for major beach cities around the world; however the beaches that have been nourished can still appear quite natural and often many visitors are unaware of the works undertaken to support the health of the beach. en.wikipedia.org /wiki/Beach   (1480 words)

DrBeach.Org Beach erosion is a national problem as 80 to 90 percent of sandy beaches are currently eroding at rates of only a few inches to over 50 feet per year along the outer coastline of Louisiana, the erosion "hot spot" of the United States. Beach nourishment is the process of adding new sand to the beach profile in order to restore it to some former width. Beach nourishment is only feasible at the community level as large sectors (e.g., miles of the shore) must be nourished to be economical viable. www.drbeach.org /drbeach/physical_therapy.htm   (1244 words)

City Feedback Page   (Site not responding. Last check: 2007-10-01) Beach Nourishment is the process of replacing sand onto beaches that have suffered erosion from storms and from the restriction of the natural sand replenishment caused by dredging inlets and passes. It is important to understand that the design of the beach nourishment project cannot have "breaks" in the middle of its length—this would allow erosion to focus on the narrower area, and greatly compromise the integrity of the project. The Pensacola Beach Chamber of Commerce informed us that it actually saw an increase in rental rates during this period, due to the tourist’s curiosity of the project and the shell-collecting activity that was a by-product of the project. www.orangebch.com /beachfaq.htm   (2389 words)

Beach Nourishment - Coastal Geology This paper reviews the objectives of constructing beach nourishment projects, the processes that are affected through the placement of the beach nourishment project, the elements of the design features employed, the potential benefits and adverse effects of beach nourishment projects and concludes with several case studies that emphasize the physical performances of these projects. Beach nourishment profiles are usually constructed at slopes steeper than natural, resulting in profile equilibration that causes a narrowing of the dry beach width that may require several years to occur as shown in Figure 3b. It is seen that nourishment with sands that are the same size as the native results in an equilibrated dry beach width of 100 feet whereas nourishment with sands 0.18 mm and 0.22 mm results in equilibrated dry beach widths of 17 feet and 150 feet, respectively. www3.csc.noaa.gov /beachnourishment/html/geo/scitech.htm   (8231 words)

Beach Nourishment - Coastal Geology The effects of structures may be used to beneficially influence a beach nourishment project by modifying the forces that cause rapid or accelerated losses from the beach and thus increase overall project performance. Beach erosion control structures can be categorized generally in three groups (Sorenson 1997) (a) structures that are attached and are perpendicular to the shoreline, (b) structures that are parallel to the shoreline and are offset seaward from the shore and (c) structures that are parallel to the shoreline and located on the visible beach. After the nourishment, it was apparent that this "hot spot" had been largely controlled by the presence of the groins added at the time of the beach fill. www3.csc.noaa.gov /beachnourishment/html/geo/shorelin.htm   (2421 words)

Beach Nourishment Info Beach nourishment is the process of dumping or pumping sand from elsewhere onto an eroding shoreline to create a new beach or to widen the existing beach. Beach nourishment is often proposed when beach erosion threatens to remove an existing beach, make it too narrow to be used, and/or when property behind an eroding beach is threatened. Publicly funded beach nourishment is worth considering only if the general public will have good access to the "new" or restored beach, AND when all parties have been informed that this solution is temporary, and will have to be repeated. www.brynmawr.edu /geology/geomorph/beachnourishmentinfo.html   (1689 words)

Sea Life Rebounds After Beach Nourishment   (Site not responding. Last check: 2007-10-01) Previous studies concluded that, in most cases, adverse impacts from beach nourishment were short-term, minor, and were outweighed by the benefits of shore protection and recreation. Beach nourishment resulted in short-term declines in abundance (numbers of animals), biomass (weight of animals), and taxa richness (numbers of different kinds of animals). Conclusions: Impacts of beach nourishment to intertidal and nearshore fauna, larval and juvenile fish assemblages, and fish food habits were minor and short-term. www.usace.army.mil /inet/functions/cw/hot_topics/beachnourishment.htm   (1524 words)

Beach Nourishment - Law and Policy   (Site not responding. Last check: 2007-10-01) One critical aspect of beach nourishment is the requirement to comply with the many federal and state laws, regulations, and policies that are associated with these complex projects. Beach nourishment is the process of placing sand on an eroding beach to provide a protective buffer against storm and wave damage, and/or to enhance the recreational value of a beach. Typical NEPA compliance issues that have arisen on various beach nourishment projects along the Atlantic seaboard and the coast of the Gulf of Mexico are summarized in Table 7. www3.csc.noaa.gov /beachnourishment/html/human/law/law.htm   (2441 words)

NJDEP Coastal Engineering - Beach Nourishment Healthy beaches provide mitigation from these natural disasters by acting as a buffer between the pounding surf and the homes, businesses and infrastructure along the coast. Beach nourishment projects consist of the initial placement of sand along a beach that has experienced erosion. The re-nourishment process consists of restoring the beach to initial conditions and usually has less time and cost associated with the project when compared to the initial nourishment. www.state.nj.us /dep/shoreprotection/nourishment.htm   (536 words)

Laudholm and Drakes Island Beaches, Maine - Before and After Beach Nourishment This nourishment occurred on the higher elevations of the beach profile in the vicinity of the berm, or area of summer sand accumulation. Six beach profiles were measured on 9/20/00, a few days before Wells Harbor dredging began and three months later on 12/19/00, soon after the dredging and beach nourishment were completed. This new accumulation is from the redistribution of the nourishment alongshore to the south by the process of longshore drift and down the profile from wave action and the influence of gravity. www.state.me.us /doc/nrimc/mgs/explore/marine/sites/oct01.htm   (773 words)

Limited Sand Resource for Eroding Beaches - West-Central Florida Coastal Studies Project   (Site not responding. Last check: 2007-10-01) Beach erosion and loss of protective dunes have left the coast susceptible to damage from storms and hurricanes. This method of beach maintenance is expensive, typically costing well over a million dollars for each mile of beach, and needs to be repeated as often as every 4 years. While beach nourishment is becoming the most common means of addressing beach erosion, it may not provide a cost- effective long-term solution, as sand resources for nourishment are limited along much of the west Florida coast. coastal.er.usgs.gov /wfla/factsheet   (1091 words)

Holmberg Technologies, Inc. Beach areas are formed from sand, shell, coral and pebble deposits that are transported to them from their original upland or seabed source off by water, or hydro effects. A natural beach typically consists of a plentiful sand supply source, deltas, sandbars that are not dredged, shallow offshore sandbars that are unbroken, and, most important of all, a wide, slowly tapering beach with healthy vegetation growing above the high tide and wave wash-up zone. The establishment and permanence of natural sand beaches are often the result of a delicate balance among a number of these factors, and any changes, natural or human-made, tend to upset this equilibrium (Inman, 1982). www.erosion.com /shore.asp   (5314 words)

Division of Water - Lake Michigan - Beach Nourishment Beach nourishment sand must be free of contaminants that might be suspended or dissolved in the water as the sand is reworked by the storm waves. First, beach nourishment sand directly protects the natural dune-bluffs from wave attack by serving as a sacrificial dune and beach buffer zone between the waves and the previously eroding natural coast. With time, beach nourishment sand is completely mobilized as it moves down the shoreline providing protection to downdrift property owners as new beaches and sand bars. www.in.gov /dnr/water/lake_michigan/coastal/beach_nour.html   (885 words)

BEACH NOURISHMENT FOR STORM PROTECTION The most common type of beach nourishment project in Massachusetts reuses clean material from nearby dredging projects, which is technically called "beach fill." The primary purpose for these projects is to keep the sand in the system and find a convenient place to unload the dredged material. The second kind of project, technically referred to as "beach nourishment," is designed by an engineer to add a specific amount of sand to a system to provide storm protection. The most important factor when designing a beach nourishment project is to make sure the new sand is "compatible" with the old sand by comparing the grain sizes. www.mass.gov /czm/coastlines/2002/c16.htm   (430 words)

Maui County - Beach Restoration and Nourishment Activities While the shoreline is retreating the beach width is maintained from sand which is naturally released from dunes and other sand reservoirs. Beach erosion in contrast, is the loss of sandy beach width as reservoirs are depleted, sand transport is hindered, or sand reservoirs are impounded by man-made hardening structures such as seawalls. As a consequence, Shoreline Setback Approvals may be granted for 'soft' approaches to beach erosion, whereas a Shoreline Setback Variance is normally required in cases where the shoreline is to be hardened. www.co.maui.hi.us /departments/Planning/czmp/beach.htm   (592 words)

Beach nourishment   (Site not responding. Last check: 2007-10-01) During storms with elevated water levels and high waves, a wide beach performs as an effective energy absorber with the wave energy dissipated across the surf zone and wide beach rather than impacting on the upland structures. There are potential environmental benefits associated with beach nourishment projects. These include increased habitat for sea animal nesting, nesting and foraging areas for sea birds, and habitat for beach flora. www.punweb.com /article/Beach_nourishment   (760 words)
