“…Storm surges are caused by long waves, therefore they are usually modeled using shallow water equations. The literature on the calculation of storm surges is quite voluminous, and here we are to mention only a few works where storm surges were simulated in the seas surrounding Russia [5][6][7][8].…”

Purpose. Investigation of the storm surge in Korsakov in the southern part of the Sakhalin Island on November 15, 2019 and comparison of the results of its numerical simulation with the data of in situ measurements constitute the aim of the article. Methods and Results. In situ measurements of the storm surge in Korsakov (the Sakhalin region) were performed and the data on the flooded area dimensions were collected. A storm period on the Sakhalin Island is almost the annual event in an autumn-winter season. The severe storm that happened in the southern Sakhalin region on November 15, 2019 led to flooding of the port territory in Korsakov. Due to the NAMI-DANCE computational complex, the storm surge was numerically simulated within the framework of the system of shallow water equations in the spherical coordinates on the rotating Earth with the regard for the friction force and the atmospheric effect. The calculations included the data on temporal and spatial distribution of the wind speed at the altitude 10 m taken from the Climate Forecast System Reanalysis database. The data on the atmospheric pressure were not applied in simulations since the atmosphere pressure gradient at the area under study was small. The simulation was carried out in the course of three days. The simulations showed that in 20 hours after the wind forcing had started, the water level in the port increased up to its maximum values, and did not fall the whole day. The water level maximum heights were concentrated in the southwestern part of the Aniva Bay. At that the calculated current speeds reached 2 m/s. During the storm, at the wind speed up to 15 m/s, the storm surge height in the Korsakov port area constituted 1.7 m, whereas the width of the flooded zone was up to 200 m. These results are confirmed well by the in situ measurement data. Conclusions. The simulation values of the power characteristics for the above-mentioned storm are represented in the paper. The Froude number square reaches 0.03 in the Korsakov city port area, and spatial distribution of the wave strength moment is up to 1 m3/s2. Field measurements and eyewitness reports confirm the evidence of a powerful impact of a storm surge upon the port constructions.

“…This is a relatively large delta with an area of >500 km 2 (Figure 3) that possesses the classical deltaic environment with high-biodiversity wetlands (Figure 4). The area is crossed by numerous meandering channels, and it is flooded occasionally and for short periods of time (a few days) by wind-driven surges from the shallow-water Azov Sea [32,33]. The upper part of the delta enters the urban territory of Rostov-on-Don with a population of >1 million.…”

River deltas boast ecosystem richness, but their efficient conservation and management require consideration of the full spectrum of natural phenomena, including those which are geological. Few specialists have explored the issue of deltaic geological heritage (geoheritage), and the relevant knowledge remains scarce and non-systematised. This paper proposes the first classification of this geoheritage. Five categories are distinguished: entire-delta geological phenomenon, delta-associated “purely” geological features, delta-associated features resulting from geology–ecosystem interactions, geological features occasional to deltas, and geoarchaeological localities in deltas. Chosen as a case example, the Don River delta in the southwestern part of Russia possesses geoheritage of these categories, except for the latter. The relevant unique geological features differ by their types and ranks. Of particular interest is the phenomenon of a self-cleaning environment which prevents mercury concentration in the soil despite pollution from natural and anthropogenic sources. The complexity of the deltaic geoheritage, its co-existence with the rich biodiversity, and the aesthetical issues make geopark creation in river deltas a sensible venture. Relevant proposals have been made for Malaysia and the Netherlands–Belgium border, and the Don River delta in Russia also presents an appropriate location for geopark creation.

Морской гидрофизический институт РАН, г.Севастополь 2 Севастопольское отделение Государственного океанографического института им. Н.Н.Зубова, г.Севастополь МАТЕМАТИЧЕСКОЕ МОДЕЛИРОВАНИЕ РАЗМЫВА И ЗАТОПЛЕНИЯ АРАБАТСКОЙ СТРЕЛКИ В ПЕРИОД ИНТЕНСИВНЫХ ШТОРМОВ В АЗОВСКОМ МОРЕ На основе морфодинамической модели XBeach выполнено исследование процессов размыва и затопления северо-восточного побережья Крымского п-ова-Арабатской стрелки (косы) под воздействием ветрового волнения и штормовых нагонов Азовского моря. С использованием данных реанализа и натурных наблюдений получены необходимые для моделирования оценки значений параметров ветрового волнения и штормовых нагонов в районе косы для штормов, возможных 1 раз в год и 1 раз в 5, 10, 25 и 50 лет. Расчеты выполнены в рамках одномерной задачи для характерного поперечного профиля косы, включающего пляж, карьер и основное тело косы. Показано, что для штормов, возможных 1 раз в год, размывается около половины пляжа, и деформации не достигают карьера. Для штормов, возможных 1 раз в 25 и 50 лет, размыву подвержен весь пляж и склон карьера, примыкающий к основному телу косы. Выявлено, что именно сочетание сильных штормовых нагонов и интенсивных ветровых волн является основным условием для возникновения размыва и затопления косы. Без учета штормовых нагонов модель не воспроизводит размывов и затопления косы.
