Mapping the morphology of intertidal areas is a logistically challenging, time consuming and expensive task due to their large expanse difficulties associated with access. A technique presented here that uses standard marine navigational radar operating at X-band frequency. The method series time-exposure images over course two-week tidal cycle identify elevation wetting drying transitions each pixel in images, thereby building up morphological map target area. This "Temporal Waterline"...

Aging coastal defences around the UK are challenging managers to redesign schemes be resilient extreme events and climate change, cost-effective, have minimal or beneficial environmental impact. To enable effective design, reduced uncertainty in assessment of flood risk due natural variability within forcing is required focus on conditions that pose highest threat. The typical standard protection for withstand a 0.5% annual probability event, historically also known as 1 200 year return...

There is a good understanding of past and present coastal processes as result monitoring programmes within the UK. However, one key challenges for managers in face climate change future vulnerability infrastructure communities to flooding. Drawing on vulnerability-led decision-centric framework (VL-DC) Decision Support Tool (DST) developed which, combines new observations modelling explore sea-level rise storms nuclear energy sites Britain. The combination these numerical projections DST...

Dungeness Foreland, southeast UK, is comprised of a series distinctive gravel ridges overlying sub- and intertidal sands. The successful application optically stimulated luminescence (OSL) to the Holocene sands at provides well-resolved chronology (precision ~5%) for exploring sedimentary response foreland changes in sea level, storms, sediment supply coastal dynamics. nature progradation revealed through three-dimensional network 35 new quartz OSL ages, these data also constrain timing...

Soil phosphorus (P) leaks rapidly from newly formed land surfaces to upland rivers and lakes, surface water P concentrations peaking early before declining as soil apatite (Ca 5 (PO 4 ) 3 (OH)) becomes depleted. We present lake sediment profiles that record this leakage through the Holocene. The results are entirely consistent with our re‐analysis of published chronosequence data, but conflict more recent quantitative interpretations global dynamics identify far slower loss rates. inherited...

A process-based numerical model is applied to investigate sediment transport dynamics and budget in tide-dominated estuaries under different salt marsh erosion scenarios. Using a typical funnel-shaped estuary (Ribble Estuary, UK) as study site, it found that the remobilization of sediments within increased result tidal inundation eroded marsh. The landward export finest also intensified. relationship between net has been be non-linear—with first 30% causing most predicted export. presence...

A low-cost “Internet of Things” (IoT) tide gauge network was developed to provide real-time and “delayed mode” sea-level data support monitoring spatial temporal coastal morphological changes. It is based on the Arduino Sigfox MKR 1200 micro-controller platform with a Measurement Specialties pressure sensor (MS5837). Experiments at two sites colocated established gauges show that these inexpensive sensors can make accurate measurements. While are capable ~1 cm accuracy, as other comparable...

Abstract The influences of sea-level, climate, human activity and coastal morphology on post-glacial sediment flux deposition in the Tees Estuary were considered a multidisciplinary investigation Late Pleistocene Holocene sedimentary record. following tripartite division was identified using combination lithostratigraphic geochemical data: Glacial laminated clay providing evidence former proglacial lake proxy record climate change; an early-mid-Holocene intercalated sequence tidal silts...

An established diatom-based tidal level transfer function is used in combination with the present day relationship between sedimentation rate and altitude to reconstruct Holocene sediment accretion for Tees estuary, northeastern England. The results from five cores reveal two periods of enhanced sedimen tation, earlier which (8000–6000 cal. BP) related relatively rapid sea-level rise increasing range. later phase increased also reflects an marine influence after c. 3000 BP, but may be...

Wave overtopping and subsequent coastal flood hazard is strongly controlled by wind water levels, especially critical in hyper-tidal estuaries where even small changes wave heights can be catastrophic if they are concurrent with high spring tide. largely attributed to amplitude shorter period, locally generated waves; while low longer period waves rarely impact low-lying zones up-estuary. Here, the effect of properties on up-estuary propagation sensitivity significant height investigated...

Abstract The combination of structure‐from‐motion with multi‐view stereo (SfM‐MVS) photogrammetry has become an increasingly popular method for the monitoring and three‐dimensional (3D) reconstruction coastal environments. Climate change is driving potential increased landward retreat meaning geomorphological using methods such as SfM‐MVS essential detecting tracking impacts. been well‐researched a variety platforms spatial temporal resolutions mainly rectilinear digital cameras in settings....

This paper provides a sensitivity analysis around how characterizing sandy, intertidal foreshore evolution in XBeach-X impacts on wave runup and morphological change of vulnerable, composite gravel beach. The study is motivated by need for confidence storm-impact modeling outputs to inform coastal management policy beaches worldwide. First, the model run with sandy settings applied capture changes foreshore, barrier assigned as non-erodible surface. Model runs were then repeated obtain...

Cadmium zinc telluride (CdZnTe or CZT) is the leading semiconductor detector for gamma spectroscopy at room temperature. In present study, a coplanar-grid CZT was used gamma-ray measurements of environmental radioactivity on contaminated saltmarsh sediment core in comparison with results from coaxial high-purity germanium to assess their comparative performance. The findings reveal that performs well both 241Am and 137Cs over broad range activities, despite limited efficiency, can be good...
