Coastal Capital: Dominican Republic: Case Studies on the Economic Value of Coastal Ecosystems in the Dominican Republic

Illustrates the benefits coralline beaches, reefs, and mangroves in various parts of the country offer, including providing protection against beach erosion, habitats for fisheries, potential tourism growth in protected marine areas, and local tourism

An investigation of environmental factors associated with the current and proposed jetty systems at Belle Pass, Louisiana

The history of the existing jetty system at Belle Pass was investigated to determine its past effect on the littoral currents and beach erosion. Present flow patterns and erosion rates were also studied, along with the prevailing recession rates of local beaches not influenced by the jetty system. Aerial photographs and maps were used in conjunction with periodic hydraulic measurements, ground observations, and physical measurements of beach erosion. A scale model was constructed to further the study of flow patterns and velocities. It is shown that the existing jetty has not adversely affected the coastline in the area; erosive processes have been retarded by the jetty and its companion groin. Future erosion patterns are predicted, and projected effects of the proposed jetty system are given

Analysis of beach erosion by storm using artificial neural network

Beach erosion by storm condition is so severe and it causes major unbalance on sand budget along the coastline. Beach erosion including overwash is complicated and difficult to analyze. The beach erosion of overwash using the artificial neural network is compared with the empirical equation developed by robust regression and experiment data in this study. Error-back propagation method is used for training artificial neural networks. The eroded volume of sand is well estimated by the artificial neural network without understanding mechanism of beach process. The study focused on onshore and offshore sediment transport by overwash on storm wave condition

AN ECONOMIC EVALUATION OF BEACH EROSION MANAGEMENT ALTERNATIVES

This paper examines the relative economic efficiency of three distinct beach erosion management policies — beach nourishment with shoreline armoring, beach nourishment without armoring, and shoreline retreat. The analysis focuses on (i) the recreational benefits of beaches, (ii) the property value effects of beach management, and (iii) the costs associated with the three management scenarios. Assuming the removal of shoreline armoring improves overall beach quality, beach nourishment with shoreline armoring is the least desirable of the three alternatives. The countervailing property losses under a retreat strategy are of the same order of magnitude as the foregone management costs when the beneficial effects of retreat — higher values of housing services for those houses not lost to erosion — are considered. The relative desirability of these alternative strategies depends upon the realized erosion rate and how management costs change over time.Resource /Energy Economics and Policy,

Economic valuation of preventing beach erosion : comparing existing and non-existing beach markets with stated and revealed preferences

Predicted climate change is likely to increase beach erosion in the future, inducing higher costs of beach maintenance. Hence, additional funds for their protection will be required. We examine the willingness to pay (WTP) of beach visitors for preventing beach erosion in the form of daily beach entrance fees in Crikvenica, Croatia, by applying the contingent valuation method. This is the first beach valuation study for this country in transition which has emerged as an important Mediterranean tourist destination. The novelty of our study is that it compares WTP estimates for an existing and a non-existing beach market. This is done by conducting a survey at the beach where an entrance fee is already levied and at the nearest open-access beach. Based on the initial (follow-up) valuation question the stated WTP per adult per day for avoiding beach erosion equals €1.69 (€1.26) for the paid beach and €2.08 (€1.84) for the free beach. In addition, the travel cost method is employed. It reveals that consumer surpluses for visiting the paid and the free beach amount to €2.57 and €1.74, respectively

Backshore erosion due to high swell waves

High swell has been known for the one of the main causes of beach erosion in the east coast of Korea. In this study, coastal topography changes due to high swells are simulated to find its effect on the backshore by using movable bed experiments and numerical experiments. Sea bottom topographical changes due to various incident waves were investigated using CSHORE model in the numerical experiments. Furthermore, the mechanism and the phenomena of beach erosion due to waves and high swells on the foreshore and backshore were analyzed and compared with movable bed hydraulic experiments

Beach erosion

During the last century, a general rise (1,5 mm/year) level is observed. This phenomenon explains the crosion of some beaches. Our research in Calvi (Corsica) show that the erosion (1,4 m/year) is mainly accelerated by the housting development in the fringing dunes and on the beach since 1980

Tracking Beach Erosion Could Help Management

Although sandy beaches represent only about one percent of Maine\u27s 3500-mile coastline, they are vitally important to the state\u27s economy as recreational resources, provide crucial wildlife habitat, and buffer the coast against storms. However, many of Maine\u27s beaches are threatened, mainly by erosion from coastal engineering and natural forces. Engineering structures-such as jetties and seawalls-built to create navigable harbors and protect, beachfront property, may impact the recreational beach. They can interfere with the natural distribution of sand and cause beaches to erode more rapidly or sand to accumulate in unwanted places. Some towns try, often without success, to fix their beaches by dredging sand from one place and dumping it in another
