Oosterlo et al. (2019) developed a system using two terrestrial laser scanners, which can measure run-up heights, depths and velocities of waves on a dike in field situations. The system has now been placed next to two overtopping tanks on a dike in the Eems-Dollard estuary in the Netherlands to measure during actual severe winter storms. The goal of the present paper is to further validate this innovative system with data obtained during storm Ciara (10 - 12 February 2020), a severe winter storm with very oblique wave attack. Furthermore, the data gathered during storm Ciara will be compared to the current knowledge on wave overtopping, to possibly gain new insights in the influence of very oblique wave attack on wave overtopping.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/TwSwJuxb-Yo

In January 2015 severe winter storms caused substantial damage to Craig Phadrig fort (Scheduled Monument 2892) after two wind-blown trees exposed a section of the inner rampart. Prior to consolidation and reinstatement, Scheduled Monument Consent was granted for an archaeological evaluation of the damaged area. This revealed three principal phases of construction, the earliest a massive timber-laced wall burnt in the 4th–3rd century bc. The upper elements of this ruined structure were incorporated into two secondary phases of refortification comprising construction of a palisade along its crest followed several centuries later by reprofiling of the rampart upper bank. The chronology of the second and third phases is more equivocal, with a single 5th–6th century ad radiocarbon date providing a terminus post quem for the erection of the palisade, while the other features indicate activity in the 11th–13th centuries.

Severe winter storms have cost the state of Missouri significant economic loss from property damage, crop destruction, and loss of livestock. Even worse than the economic loss from these storms are the injuries and deaths to humans that they sometimes cause. A severe winter storm is a storm with six inches or greater snowfall in 48 hours and/or an ice storm with [1/4] inch or greater ice accumulation from the storm. A severe winter storms climatology for Missouri from 1960-2010 was created to better understand the development, frequency, and intensity of severe winter storms in Missouri. From the climatology, it was found that heavy snowfall events were by far the most common severe winter storm type in Missouri with 318 heavy snowfall events. Heavy ice events were the second most common with 66 events. Texas/West Gulf originating mid-latitude cyclones was responsible for the majority of severe winter storms in Missouri followed by Colorado originating mid-latitude cyclones. When looking at El Nino Southern Oscillation (ENSO) variability with heavy snowfall events, there is only a slight variation between the number of heavy snowfall events and the phase of the ENSO cycle they occur in. When all of the heavy snowfall events were averaged together there was only a slight difference in the average number of events per winter season during the negative phase of the Pacific Decadal Oscillation (PDO) (6.2) and the number of events per winter season during the positive phase of the PDO (6.5). When all heavy snowfall events were averaged together there is a 1.4 difference in the average number of events per year during the negative phase of the North Atlantic Oscillation (NAO) (4.6) and the positive phase of the NAO (6). Shelter Mutual Insurance Company provided insurance data from 2000-2010 for 56 severe winter storms in Missouri. Claim payouts for these storms totaled $28,543,020.65. Data from the Missouri Department of Transportation (MoDOT) for automobile accidents on Missouri interstates from 2000-2010 showed that there was the most snowfall related automobile accidents when snowfall was between 0-2.9 inches. The number of automobile accidents decreased with increasing snowfall amounts.
