The chronicles of nearshore morphology and surficial beach deposits provide valuable information about the nature of the beach condition and the depositional environment. It imparts an understanding about the spatial and temporal relationship of nearshore waves and its influence over the distribution of beach sediments. This article contains data about wave and sediment dynamics of the ten sand...

Following a major beach closure due to bacterial contamination, a survey of beachgoers was conducted in Huntington Beach, California in 1999 to assess perceived health risk from swimming. Responses were compared to those of beachgoers at the unaffected Laguna Main Beach. No significant differences were found in risk perception. Respondents were aware of the closures (83%), yet the majority (83%...

Beach rock has only rarely been observed in the coasts. It is a hard costal sedimentary formations consisting of various beach sediments, lithified through the precipitation of carbonate cements. One such formation is noted on the South East Coast of Tamilnadu, India. The objective of this contribution is to collect and review information on reported occurrences, characteristics and formation m...

Coastal visits not only provide psychological benefits but can also contribute to the accumulation of rubbish. Volunteer beach cleans help address this issue, but may only have limited, local impact. Consequently, it is important to study any broader benefits associated with beach cleans. This article examines the well-being and educational value of beach cleans, as well as their impacts on ind...

Sediment deprivation from dam installments contributes to beach erosion yet the underlying physical and economic factors linking them together have traditionally been isolated during regional planning. In order to gain a better understanding of the behavior of a managed beach system, a dynamic simulation model was developed incorporating physical and monetary factors influencing the amount of a...

The amount of wrack deposited and retained on a beach may be affected by the beach’s morphology. Conversely, wrack deposits have the potential to modify sediment dynamics on the beach face through accumulation and erosion of sediments around wrack deposits, and the incorporation of organic matter into beach sands. The aims of this chapter were thus to determine whether beach morphology differed...

Solid wastes are commonly found on Malaysian beaches as any other parts of the world. Generally known as beach debris, this particular type of waste is treated similar to other municipal waste in Malaysia where 95% of it will be disposed off into landfills. Studies were conducted on four beaches in Peninsular Malaysia namely Teluk Kemang, Pasir Panjang, Batu Burok, and Seberang Takir. The objec...

although there exist advanced models which predict beach profile for natural beaches, the behavior of the beaches in front of seawalls still suffers from the lack of appropriate theoretical models and sufficient measured data. in this paper, following the results obtained from the measurements, a beach profile evolution model is developed, using the measured probability distribution of the near...

Innovative methodology based on a combination of Real Time Kinematic GPS (RTK-GPS), lidar, and open source GIS was developed to gain a better understanding of rapid changes in coastal topography. Improved spatial interpolation techniques were implemented to produce detailed topographic surfaces from lidar and RTK-GPS data. The methodology is demonstrated for two North Carolina areas: Jockey's R...

The sitting beach-chair position is regularly used for shoulder surgery and anesthesia may be induced in that position. We tested the hypothesis that the cardiovascular challenge induced by induction of anesthesia is attenuated if the patient is placed in a reclining beach-chair position. Anesthesia was induced with propofol in the sitting beach-chair (n = 15) or with the beach-chair tilted bac...
