Abstract:

Beaches and coastal environments are dynamic, constantly shaped and reshaped by natural processes and anthropogenic modifications. The morphodynamics and influence of natural and anthropogenic factors of two different coasts at various temporal and spatial scales are discussed. To quantify the performance of several beach nourishment projects at annual temporal and kilometer spatial scales on three adjacent microtidal low-wave energy barrier islands in west-central Florida, a total of 5,200 beach and nearshore-profiles spaced at 300 m were surveyed monthly to bi-monthly from 2006-2010.

Abstract:

The role of high energy events in determining beach morphology on mixed sand and gravel barrier beaches is examined. Analysis of the beach response to high energy events contributes to the understanding of the significance of these events in determining the general and long term function of mixed sand and gravel beach systems. Issues concerned with the contribution of events of differing sizes to the geomorphic character of landforms are an ongoing area of debate in geomorphology. The concepts of magnitude and frequency of events, and thresholds or turning points in the behaviour of geomorphol

Abstract:

Exposed sand beaches are increasingly under pressure from human population growth and recreation. Activities, such as vehicle driving and horse riding, can pose a significant threat to specialist fauna living in the sediment. Few studies have evaluated how vehicles affect sand beach fauna and none have examined the impacts of horse users on burrowing bivalves. The research questions addressed were: do vehicles and/or horses on sand beaches impact on intertidal shellfish populations? Following on from this, can management policies mitigate any negative impacts from such activities on sand beach

Abstract:

Mixed sand and gravel beaches are an important means of sea defence. The majority of beaches in the south coast of the UK are of the mixed type and beach replenishment is generally needed in order to maintain the effectiveness of these beaches against storm wave attacks. Despite vigorous research efforts in recent years, coastal engineers still do not have a reliable method to estimate the sediment budget in their designs. In addition, there is also a lack of understanding of the impacts of beach maintenance activities, such as recycling and re-profiling, on the performance of the beach and on

Abstract:

During the last two decades several field studies have shown a clear pattern in the cross-shore sediment transport processes on beaches. Outside the surf zone, the stronger onshore velocities under unbroken (Stokes-type) wave crests, produce a dominant onshore sediment transport. Inside the surf zone, strong offshore-directed mean currents (undertow) drive sediments offshore. It is of great interest for the scientific community to verify further the consistency of this pattern under different morphodynamic conditions, understand the underlying physics and quantify/parameterise this behaviour i

This thesis examines the processes of longshore sediment transport in the swash zone of a mixed sand and gravel shoreline, Lake Coleridge, New Zealand. It focuses on the interactions between waves and currents in the swash zone and the resulting sediment transport. No previous study has attempted to concurrently measure wave and current data and longshore sediment transport rates on a mixed sand and gravel lakeshore beach in New Zealand. Many of these beaches, in both the oceanic and lacustrine environments, are in net long-term erosion. It is recognised that longshore sediment transport is a

Realistic, reliable, and effective modeling of cross-shore sediment transport is not present in the current literature. Building that model requires the accurate recreation of breaking wave processes in the nearshore.

The COULWAVE model is selected for robust testing. Testing of the COULWAVE model shows that, although capable of recreating realistic results, it does not adequately describe major wave characteristics in the surf zone, ac

This hypothesis stated that more species are present on fine grained, flat dissipative beaches due to a more benign swash climate. It suggested that, as beach morphodynamics change to reflective conditions, which is experienced on coarse, steep beaches, few species can survive; these beaches are therefore characterised by lower macrofaunal diversities, abundance and biomass.
