A Design Parameter for Reef Beach Profiles—A Methodology Applied to Cadiz, Spain

Abstract

The southwestern coast of Spain is in a tidal zone (mesotidal) which causes the equilibrium profile to be developed in two different sections: the breakage section and the swash section. These two sections give rise to the typical bi-parabolic profile existing in tidal seas. The existence of areas with reefs/rocks which interrupt the normal development of the typical bi-parabolic profile causes different types of beach profiles. The objective of this article is designing an easy methodology for determining new formulations for the design parameters of the equilibrium profile of beaches with reefs in tidal seas. These formulations are applied on 16 profiles to quantify the error between the real profile data and the modelling results. A comparative analysis is extended to the formulations proposed by other authors, from which it is found that better results are obtained with the new formulations.

Analysis of Topographic Surveys with RPAS in Steep Coastal Dunes

“…The different variables necessary for the correct planning of flights (the flight height, transversal and longitudinal overlaps, flight time, and number of GCPs/Ha) were defined according to Contreras-de-Villar et al [22], and the flight parameters required to minimize the time and the topographic errors are shown in Table 1. In order to complement previous studies [34,35,37], two new parameters were considered in this work:…”

“…The end result is a sand deposit with a NE-SW orientation, as seen in Figure 1b, with steep sand profiles. Data on the slopes can be found in [35]. From a scientific and sociological perspective, it is highly impactful [33].…”

Increase in the Erosion Rate Due to the Impact of Climate Change on Sea Level Rise: Victoria Beach, a Case Study

“…The study area is a mesotidal environment and the tidal range reaches 3.81 m. At low tide, the width of Victoria Beach is around 200 m and the length is around 3000 m. It is dissipative with a moderate-low slope. The beach has a sand-rich biparabolic profile [11,12].…”
