A Field Experiment on a Nourished Beach
CHAPTER 157 A Field Experiment on a Nourished Beach A.J. Fernandez* G. Gomez Pina * G. Cuena* J.L. Ramirez* Abstract The performance of a beach nourishment at" Playa de Castilla" (Huel- va, Spain) is evaluated by means of accurate beach profile surveys, vi- sual breaking wave information, buoy-measured wave data and sediment samples. The shoreline recession at the nourished beach due to "profile equilibration" and "spreading out" losses is discussed. The modified equi- librium profile curve proposed by Larson (1991) is shown to accurately describe the profiles with a grain size varying across-shore. The "spread- ing out" losses measured at " Playa de Castilla" are found to be less than predicted by spreading out formulations. The utilization of borrowed material substantially coarser than the native material is suggested as an explanation. 1 INTRODUCTION Fernandez et al. (1990) presented a case study of a sand bypass project at "Playa de Castilla" (Huelva, Spain) and the corresponding monitoring project, that was going to be undertaken. The Beach Nourishment Monitoring Project at the "Playa de Castilla" was begun over two years ago. The project is being *Direcci6n General de Costas. M.O.P.T, Madrid (Spain) 2043 2044 COASTAL ENGINEERING 1992 carried out to evaluate the performance of a beach fill and to establish effective strategies of coastal management and represents one of the most comprehensive monitoring projects that has been undertaken in Spain. This paper summa- rizes and discusses the data set for wave climate, beach profiles and sediment samples. 2 STUDY SITE & MONITORING PROGRAM Playa de Castilla, Fig. 1, is a sandy beach located on the South-West coast of Spain between the Guadiana and Gualdalquivir rivers.

3.2.6. Methods for Field Measurement and Remote Sensing of the Swash Zone
© Author(s) 2014. CC Attribution 4.0 License. ISSN 2047-0371 3.2.6. Methods for field measurement and remote sensing of the swash zone Sebastian J. Pitman1 1 Ocean and Earth Sciences, National Oceanography Centre, University of Southampton ([email protected]) ABSTRACT: Swash action is the dominant process responsible for the cross-shore exchange of sediment between the subaerial and subaqueous zones, with a significant part of the littoral drift also taking place as a result of swash motions. The swash zone is the area of the beach between the inner surfzone and backbeach that is intermittently submerged and exposed by the processes of wave uprush and backwash. Given the dominant role that swash plays in the morphological evolution of a beach, it is important to understand and quantify the main processes. The extent of swash (horizontally and vertically), current velocities and suspended sediment concentrations are all parameters of interest in the study of swash processes. In situ methods of measurements in this energetic zone were instrumental in developing early understanding of swash processes, however, the field has experienced a shift towards remote sensing methods. This article outlines the emergence of high precision technologies such as video imaging and LIDAR (light detection and ranging) for the study of swash processes. Furthermore, the applicability of these methods to large-scale datasets for quantitative analysis is demonstrated. KEYWORDS: run-up, morphodynamics, coastal imaging, video, LIDAR.

Received: 30 May 2014; in revised form: 7 July 2014 / Accepted: 18 July 2014 / Published: 25 July 2014 Abstract: Atoll islands are subject to a variety of processes that influence their geomorphological development. Analysis of historical shoreline changes using remotely sensed images has become an efficient approach to both quantify past changes and estimate future island response. However, the detection of long-term changes in beach width is challenging mainly for two reasons: first, data availability is limited for many remote Pacific islands. Second, beach environments are highly dynamic and strongly influenced by seasonal or episodic shoreline oscillations. Consequently, remote-sensing studies on beach morphodynamics of atoll islands deal with dynamic features covered by a low sampling frequency. Here we present a study of beach dynamics for nine islands on Takú Atoll, Papua New Guinea, over a seven-decade period. A considerable chronological gap between aerial photographs and satellite images was addressed by applying a new method that reweighted positions of the beach limit by identifying “outlier” shoreline positions.

The phenomena associated with vorticity and turbulence structures measured are summarised, including the measurement techniques and the laboratory generation of breaking waves or of flow fields sharing several characteristics with breaking waves. The effect of air entrapment during breaking is discussed. The limits of the present knowledge, especially in modelling a two- or three-phase system, with air and sediment entrapped at high turbulence level, and perspectives of future research are discussed.

They were formed your notes in a chart or web as you read. by the movement of water. The constant action of waves breaking against the cliffs slowly wore them away, leaving behind pillarlike formations. Waves continue to wear down the pillars and cliffs at the rate of about two centimeters (one inch) a year. In the years to come, the waves will likely wear away the stone pillars completely. The force of waves, powered by wind, can wear away rock and move thousands of tons of sand on beaches. The force of wind itself can change the look of the land. Moving air can pick up sand particles and move them around to build up dunes. Wind can also carry huge amounts of fine sediment thousands of kilometers.

Chapter 43 Turbulence Scales in the Surf And
CHAPTER 43 TURBULENCE SCALES IN THE SURF AND SWASH Reinhard E. Flick California Department of Boating and Waterways and Ronald A. George Center for Coastal Studies-0209 Scripps Institution of Oceanography La Jolla, California, USA 92093-0209 Abstract Ocean surface gravity waves breaking on gently sloping beaches generate sub- stantial turbulent velocity fluctuations, both from overturning at the surface bore and from shear stresses at the bottom. We have used measurements made with laboratory-style hotfilm anemometers in the surf and swash on a natural beach to determine the relevant length and velocity scales. Battjes (1975) has pointed out the importance of determining the turbulence scales in the surf zone. Modelers, such as Svendsen and Madsen (1984), for example, rely on length and velocity scale esti- mates to parameterize and solve the complicated equations that govern surf zone flows. We find that turbulence length scales depend essentially on the bore height, and therefore on the local depth, but may decrease sharply under the bore. We also determine that at least the horizontal velocities approach isotropy at frequencies of 2 to 3 Hz, which turn out to also correspond to length scales on the order of the local depth. Introduction The determination of "scales" plays an important role in turbulence research, since turbulent flows must be described by their characteristic times, lengths, veloci- ties, kinetic energies, Reynolds stresses, eddy viscosities and dissipation rates. Much of the theory of turbulence is concerned with establishing connections and relationships between these parameters and much experimental effort has gone into guiding these concerns. The basic reason why this approach is necessary, is that tur- bulent flows typically contain velocity fluctuations at a broad range of length scales, particularly small ones, so that direct analytical or numerical solution of the govern- ing equations is unmanageable.
