Survey Techniques to Examine Morphological Evolution of Coastal Regions
Beaches are dynamic, changing with tides, winds, and waves. Here, a beach was mapped daily for 3 weeks from the dune to the low-tide water line on the Outer Banks of North Carolina at the US Army Corps of Engineers Field Research Facility in Duck. The 22,500 m2 area of interest was surveyed daily …

Comparing UAV and Pole Photogrammetry for Monitoring Beach Erosion
Sandy beaches are vulnerable to extreme erosion during large storms, as well as gradual erosion processes over months and years. Without monitoring and adaptation strategies, erosion can put people, homes, and other infrastructure at risk. To effectively manage beach resources and respond to …

Evaluating Interferometric Synthetic Aperture Radar Coherence for Coastal Geomorphological Changes
… applied to Earth surface displacement analysis and topographic reconstruction. Two complex coherent SAR acquisitions of the same scene are combined to form an interferogram from which surface displacement or terrain measurements are made. The similarities between both SAR signals is captured in …

Improving the spatio-temporal characterisation of South Africa's dynamic coastal zone using hyper-temporal satellite imagery
Coastal zones, the interface between the marine and terrestrial realms, are highly productive regions that deliver critical goods and services, while facing many pressures from urbanisation, industrial development, overexploitation, pollution and climate change. Their effective management is …

The effect of bombardment of small bodies on the evolution of atmospheres of terrestrial bodies
… a great degree of diversity in their mass and composition. Impacts onto these bodies by smaller objects, such as asteroids, comets and planetesimals left over after terrestrial planet formation are evidenced by crater observations, and are an inevitable outcome of dynamical simulations of …

Writing Coastlines: Locating Narrative Resonance in Transatlantic Communications Networks
… word ‘writing’ refers both to the act of writing and to that which is written. The act of writing translates aural, physical, mental and digital processes into marks, actions, utterances, and speech-acts. The intelligibility of that which is written is intertwined with both the context of its …

Fluvial and climatic controls on tropical agriculture and adaptation strategies in data-scarce contexts
… the progressive increase in both frequency and intensity of extreme events. Even though the problem is global, it has proved to have very different societal and environmental impacts at local level, further widening the gap between disadvantaged and advantaged communities, according to the …

Controls on and Morphodynamic Effects of Width Variations in Bed-load Dominated Alluvial Channels: Experimental and Numerical Study
Understanding and predicting the effects of width variability and the controls on width adjustment in rivers has a key role in developing management approaches able to account for the physical, ecological and socio-economical dimensions of a river system. Width adaptation in a river occurs due to …
