“…A coastline can be defined as the line of contact between a water body (ocean or sea) and a land mass at an in stant in time (Gens, 2010). It is currently estimated that erosion is occurring at over 70% of beaches worldwide (Fitton, 2018). Erosion can impact on coastlines by causing damage to real estate, infrastructure and ecosystems (Li & Gong, 2015).…”

Abstract. With recent advancements in UAV based technology the use of airborne photogrammetry and LiDAR poses a new and effective approach for continuous, fast and efficient beach monitoring surveys. This paper aims to compare three platforms (a DJI Phantom Pro 4 using Ground Control Points, a DJI Matrice 200 with built in PPK allowing direct georeferencing and a DJI Matrice 600 with a Riegl Mini-VUX LiDAR system) in order to assess if they enable beach surveys to be performed efficiently, accurately and cost- effectively. A series of beach surveys were performed over a period of 6 months enabling the ability of each UAV surveying technique to be assessed for the identification and evaluation of trends in the changing topography of beaches and shorelines. The study area (Warnbro Sound, Western Australia) is an area that has experienced significant coastal change over the last 20 years as well as several serious weather events in the course of this research. The results show a significant positive bias of a consistent vertical offset to the ground surface by 4&ndash;9&thinsp;cm between the two image based systems in comparison to the LiDAR system. Although these height offsets are significant it is still within the accuracy required to perform successful beach surveys, and all systems were able to quantify the change of the beach shoreline in area (m2) and volume (m3).

“…First, the natural hazards that have historically affected the study region are identified and characterized, while the exposure to each natural hazard is spatially determined and a level of exposure ranging between 0 (low exposure) to 2.5 (high exposure) is assigned. Based on the standard of recent coastal cities vulnerability studies [37][38][39], and when qualitative information is available, physical and socio-economical dimensions were considered in the vulnerability assessment of the different components analyzed. Then, a level of vulnerability ranging between 0 (no vulnerability) and 4 (high vulnerability) was assigned to every component evaluated using a matrix.…”

Multi-hazard evaluations are fundamental inputs for disaster risk management plans and the implementation of resilient urban environments, adapted to extreme natural events. Risk assessments from natural hazards have been typically restricted to the analysis of single hazards or focused on the vulnerability of specific targets, which might result in an underestimation of the risk level. This study presents a practical and effective methodology applied to two Chilean coastal cities to characterize risk in data-poor regions, which integrates multi-hazard and multi-vulnerability analyses through physically-based models and easily accessible data. A matrix approach was used to cross the degree of exposure to floods, landslides, tsunamis, and earthquakes hazards, and two dimensions of vulnerability (physical, socio-economical). This information is used to provide the guidelines to lead the development of resilience thinking and disaster risk management in Chile years after the major and destructive 2010 Mw8.8 earthquake.

“…As with fluvial geomorphology, an emerging theme in coastal geomorphology has been a focus on erosion and flood risk assessment, and the combined impact on coastal communities, assets and infrastructure. Recent national-scale quantification of the extent and rate of coastal erosion has established an increased change that is likely to be driven by a combination of rising sea-level, reduction in sediment supply and enhanced storm-wave impact, in addition to the unforeseen negative impact of human activity at the coast in the form of structural defence works Dawson et al 2012;Fitton et al 2016Fitton et al , 2018Hansom et al 2017). The Dynamic Coast project has established that, compared to the period between the 1890s and 1970s, the period since the 1970s has seen an increase of 39 % in the linear extent of erosion on Scottish beaches, together with a doubling of the average rate of erosion to 1 m per year (http://www.dynamiccoast.com).…”

Quaternary deposits and landforms are an integral component of Scotland's geodiversity and natural heritage with intrinsic, scientific, educational, cultural, aesthetic and ecological values. Their conservation is founded on the assessment and safeguard of key protected areas principally for their scientific values. The evaluation of site networks for Quaternary deposits and landforms (including glacial, fluvial, coastal, mass movement, karst and cave features) has evolved since the late 1940s, culminating in the Great Britain Geological Conservation Review (GCR) site assessments undertaken principally between 1977 and the early 1990s. Significant scientific progress since then has arisen, for example, from re-investigation of existing sites and discoveries of new sites, developments in geochronology and the formulation and application of new concepts and models. Both the GCR site lists and the supporting site documentation now require updating in the light of this progress. Today there is greater emphasis on the wider, non-scientific values of geoconservation including, for example, on ecosystem services, links with biodiversity and cultural heritage, geotourism and the benefits for human health and wellbeing through improved understanding of dynamic landscapes, climate change and natural hazards. Involvement of wider public support beyond the geoscience community and fostering better integration of geoheritage within the developing nature conservation agenda, including a land systems approach, protected area planning and management, natural capital and connecting people and nature, will help further to protect our Quaternary geoheritage.
