New Methodology for the Classification of Gravel Beaches: Adjusted on Alicante (Spain)

Abstract

Aragonés, L.; López, I.; Villacampa, Y.; Serra, J.C., and Saval, J.M., 2015. New methodology for the classification of gravel beaches: Adjusted on Alicante (Spain).

Morphological classification of microtidal sand and gravel beaches

“…The sandy beaches of Valencia and Alicante have been added to the classification proposed by Aragonés et al (2015) for gravel beaches. Sandy beaches were classified into 4 groups based on their morphology (Fig.…”

“…Once each of the groups where the beaches are classified were determined, variables involved in their classification were also determined, for which party the same 45 variables were used by Aragonés et al (2015) for classification of gravel beaches. Using the same methodology (comparison of pairs of variables and beach types, and discriminant analysis) for the reduction of variables, and analysing these variables has been reduced to 14.…”

“…The research developed in this article started from the study by Aragonés et al (2015), in which by a discriminant analysis, gravel beaches were classified into 5 groups, depending on the distribution and proportion of sediment in the beach: Type 1: Sand and gravel beaches, Type 2: Sand and gravel separated beaches, Type 3: Gravel and sand beaches, Type 4: Gravel and sand separated beaches, and Type 5: Pure gravel beaches. Type 1 and 2 are distinguished from type 3 and 4 in the percentage of sand, the percentage of sand higher in the first two types.…”

“…Different available methods were used (discriminant analysis, SVM and neural network). The methodology proposed by Aragonés et al (2015) was used. A discriminant analysis was applied but the results were not as satisfactory as those of the gravel beaches.…”

Coastal barriers from Argentina: Buenos Aires, Patagonia and Tierra del Fuego

“…While in sand barriers the reworking (cannibalisation) is difficult to recognize, in gravel barriers these processes can be more easily described in regard that they are not subject to aeolian reworking or dense forestations. In an attempt to classify gravel beaches the proportions and distribution of sand and gravel were discriminated into 5 types: sand and gravel mixed, sand with gravel segregated, gravel with sand mixed, gravel with sand segregated, and gravel beaches (Aragonés et al 2015) In the present review, a comparative analysis and the evolutionary trends of the barriers of Argentina were described. Although some barriers located in touristic areas of Buenos Aires were subject to detailed descriptions, other barriers composed dominantly by gravel from Patagonia and Tierra del Fuego (figure 1) are fairly known.…”
