Abstract This article addresses the southern sector of the Curonian Spit, the largest coastal barrier of the Baltic Sea. A comparative analysis of the deposits that make up parts of the Curonian and Vistula Spits is given. The detailed analysis of the geological and geomorphological structure of the southern part of the Curonian Spit suggests that, within this sector, it is not a sedimentary barrier created by wave action and Aeolian processes in the Holocene, but a part of a pre-Holocene fluvioglacial plain. Field work has shown that the ancient alluvial or fluvioglacial plain is in the lagoon shore of the Vistula Spit.
本文讨论了波罗的海最大的海岸屏障库尔斯沙嘴的南部部分。对构成库尔纪和维斯瓦火山的部分矿床进行了对比分析。对库尔斯沙嘴南部地质地貌结构的详细分析表明,在这一区域内,它不是由全新世波浪作用和风成过程形成的沉积屏障,而是全新世前河流冰川平原的一部分。野外考察表明,古冲积平原或河流冰川平原位于维斯瓦沙嘴的泻湖岸边。

Abstract The paper presents the results of numerical calculations of the stability and deformation process of several idealized slopes performed by the elasto-plastic finite difference method, using the commercial codes FLAC3D and FLAC2D. The results of 3D analysis of these slopes are compared with those obtained by the 2D method. The behaviour of slopes of different shapes and inclinations was analyzed. The calculations were carried out for flat, concave and convex slopes inclined at 30°, 45° and 60°, taking into account the influence of the lateral constraints of the slope. Two variants of the medium were analysed, i.e. the mass with no friction and with no cohesion. A comparison of 3D calculation results with those obtained by the 2D limit equilibrium analysis indicates that the 3D approach produces almost always higher safety factors than does the 2D method.
摘要本文采用FLAC3D和FLAC2D商用程序,用弹塑性有限差分法对几种理想边坡的稳定性和变形过程进行了数值计算。对这些边坡的三维分析结果与二维分析结果进行了比较。分析了不同形状和倾斜度边坡的受力特性。考虑到边坡侧向约束的影响,对倾斜为30°、45°和60°的平坦、凹和凸边坡进行了计算。分析了介质的两种变体,即无摩擦和无黏聚的质量。三维计算结果与二维极限平衡分析结果的比较表明,三维方法几乎总是比二维方法产生更高的安全系数。

Transport of Fine Sediments in MarineWaterbodies Near River Mouths: Preliminary Results 河口附近海洋水体中细小沉积物的输运:初步结果

Abstract Transport of fine sediments depends mainly on the efficiency of flocculation. Flocculation, understood as the result of simultaneous processes of aggregation of particles and floc break-up, is a common phenomenon in marine environments. It is typical of fine sediments. This study presents a mathematical model of fine sediment transport. A model of flocculation is an important part of this model. Its main assumption is that flocculation is governed by turbulence. The model was qualitatively tested in a simplified theoretical waterbody. Such factors as the wind direction, wind speed, river discharge and concentration of suspension in the river were investigated. The results show that the proposed model describes reasonably well the lithodynamic processes characteristic of fine flocculating sediments. Thus it seems possible to apply it for description of fine sediment transport under real wave–current conditions that occur in many marine waterbodies near river mouths.
细粒沉积物的输运主要取决于絮凝效果。絮凝是海洋环境中常见的一种现象,是颗粒聚集和絮体破碎同时发生的结果。它是典型的细沉积物。本文提出了细粒泥沙输运的数学模型。絮凝模型是该模型的重要组成部分。它的主要假设是絮凝是由湍流控制的。在一个简化的理论水体中对模型进行了定性检验。研究了风向、风速、河道流量、河道悬浮物浓度等影响因素。结果表明,该模型较好地描述了细粒絮凝沉积物的岩石动力学过程特征。因此,似乎有可能将其应用于描述发生在河口附近的许多海洋水体中的实际波浪流条件下的细泥沙输运。

Abstract The paper presents recent investigations of beach run-up phenomena at the Coastal Research Station of the Institute of Hydro-Engineering of the Polish Academy of Sciences at Lubiatowo, Poland. The local beach is typical of open-sea coasts of the south Baltic Sea, featuring multiple longshore bars that form predominantly dissipative systems. Measurements were taken to verify the existing formulas for the run-up height, bearing in mind that they had been derived for entirely different, oceanic conditions. The results indicate that these formulations can be adapted to south Baltic Sea conditions. This however, will require significantly larger data sets, which we intend to obtain in the near future.
摘要本文介绍了位于波兰卢比亚托沃的波兰科学院水利工程研究所海岸研究站最近对海滩上升现象的调查。当地海滩是波罗的海南部公海海岸的典型海滩,其特征是多个沿岸沙坝,这些沙坝主要形成耗散系统。进行测量是为了验证现有的助跑高度公式,考虑到这些公式是针对完全不同的海洋条件推导出来的。结果表明,这些配方可以适应波罗的海南部的条件。然而,这将需要更大的数据集,我们打算在不久的将来获得这些数据集。

Abstract The paper presents the main theoretical concepts related to methods of calculating the erosion rate for sandy dunes on natural coasts, namely, the beach equilibrium profile and incident waves. To illustrate calculations of dune erosion in the vicinity of the Coastal Research Station (CRS) in Lubiatowo, the Xbeach model (an incident wave model) was used. The calculations were carried out for hydrological and hydrodynamic conditions that accompanied Hurricane Ksawery (December 6–8, 2013). The results of the calculations were compared with the measured data. A satisfactory agreement was obtained between the predicted and measured results.

Case-Study Modelling Analysis of Hydrodynamics in the Nearshore of the Baltic Sea Forced by Extreme Along-shore Wind in the Case of a Cross-shore Obstacle 跨岸障碍物情况下波罗的海近海极端沿岸风强迫的流体动力学案例研究建模分析

Abstract In the current study we use a three-dimensional model with hydrodynamic and spectral wave modules operating in a coupled mode to simulate the response of currents and wind wave fields to winds of 20–25 m/sec offshore of the protective structure of the Saint Petersburg Flood Prevention Facility Complex. The model was calibrated against field data, which allowed us to obtain a tool describing storm situations in the eastern part of the Gulf of Finland with a satisfactory accuracy. The numerical modeling showed that the protective dam did not have a noticeable effect on the levels of stormsurge, significantwave height, or current speed in areas seaward of the dam. The increase in erosion processes on the southern shore of the easternmost part of the Gulf of Finland in recent past has most probably been related to other factors. We found that if a west or south-west wind of at least 25 m/s blows over the Baltic Sea for at least 16 hours, the level of storm surges seaward of the dam may reach 3 or more meters. An artificial strengthening of the coastline and the creation of shore protection structures are recommended.
摘要:本研究采用水动力和谱波模块耦合运行的三维模型,模拟了圣彼得堡防洪设施综合体防护结构在20-25 m/sec风速下的海流和风波场响应。该模型是根据现场数据进行校准的,这使我们能够获得一种描述芬兰湾东部风暴情况的工具,准确度令人满意。数值模拟结果表明,防护坝对大坝向海区域的风暴潮水平、显著波高和水流速度没有显著影响。近年来芬兰湾最东端南岸侵蚀过程的增加很可能与其他因素有关。我们发现,如果在波罗的海上吹至少25米/秒的西风或西南风至少16小时,大坝向海的风暴潮水位可能达到3米或更高。建议人工加固海岸线和建立海岸保护结构。

Abstract A review of morphological and morphodynamic studies of the coast of the Kaliningrad oblast has been carried out for half a century. The studies include monitoring measurements by the Atlantic Branch of the Shirshov Institute of Oceanology of the Russian Academy of Sciences (AB IO RAS) with the participation of the state institute Baltberegozashchita (BBZ), as well as pre-war studies and cartographic analyses of long-term coastline migration carried out by the private company Baltic Aerogeodetic Enterprise (BaltAGE). It shows the spatial alternation of abrasive and accumulative areas, as well as frequent changes in beach width and height within the same morphological coast type. A change in the development trend of particular coast sections from year to year was noted. The significant influence of anthropogenic factors on the coastal development was emphasized, including changes in the direction of coastal retreat/advance along an extensive coastal stretch. Comparison of the interannual and nearly century-old dynamics of the coast revealed noticeable differences between them, with opposite trends in several large-scale coast sections.
摘要半个世纪以来,加里宁格勒州海岸的形态和形态动力学研究取得了长足的进展。这些研究包括由俄罗斯科学院Shirshov海洋学研究所(AB IO RAS)在国家研究所Baltberegozashchita (BBZ)的参与下进行的监测测量,以及由私营公司波罗的海航空测量企业(BaltAGE)进行的战前研究和长期海岸线迁移的制图分析。在同一形态海岸类型中,砂积区和砂积区在空间上的交替,以及滩宽和滩高的频繁变化。人们注意到,特定海岸段的发展趋势每年都在变化。强调了人为因素对海岸带发展的显著影响,包括海岸带大范围内退进方向的变化。通过年际和近百年的海岸动态对比,发现两者之间存在显著差异,在几个大尺度海岸断面上趋势相反。

Abstract The article presents estimations of coastline retreat and advance in Kaliningrad Oblast at 85 monitoring points for a ten-year period of 2007–2017, based on monitoring data supplemented with satellite image analysis. The mean annual rate of coastline retreat and advance was estimated in general for each of the four major morpholithodynamic segments of the coastline: the Vistula (−0.2 m/year) and Curonian (−0.4 m/year) spits, as well as the western (−0.5 m/year) and northern (−0.2 m/year) shores of the Sambia Peninsula. The analysis of the shore protection measures implemented in Kaliningrad Oblast from 2007 to 2017 showed that the length of protected shore segments increased by 30% to 14.5 km, which is 10% of the total coastline. The obtained scheme of long-term mean annual rates of coastline retreat and advance clearly demonstrates an uneven distribution of eroded segments along the shores of Kaliningrad Oblast, however the sea shore of Kaliningrad Oblast is mainly susceptible to erosion (44%). Accumulative segments of the shore make up only 17% of the total coastline, and the remaining 39% of the shore is relatively stable. The results obtained demonstrate that the long-term mean annual rate of coastline retreat has decreased to −0.3 m/year from −1 m/year in the earlier period of 2000–2010. The general condition of the entire coastline of Kaliningrad Oblast can therefore be described as relatively sustainable]. The changes are related to several factors, such as an increase in the length of protected shore segments, the resumption of sand pulp dumping in the beach area by the Amber Mining Plant, and an increase in the amount of analytical data from an expanded local monitoring network.
摘要本文基于监测数据和卫星图像分析,对加里宁格勒州85个监测点2007-2017年10年间的海岸线后退和推进进行了估算。对4个主要的地貌动力学段海岸线后退和推进的平均年速率进行了总体估计:维斯瓦(- 0.2 m/年)和库尔纪(- 0.4 m/年)喷口,以及Sambia半岛的西部海岸(- 0.5 m/年)和北部海岸(- 0.2 m/年)。对2007年至2017年加里宁格勒州实施的海岸保护措施的分析表明,受保护的海岸段长度增加了30%,达到14.5公里,占总海岸线的10%。所获得的海岸线后退和推进的长期平均年速率方案清楚地表明,加里宁格勒州沿岸的侵蚀段分布不均匀,但加里宁格勒州的海岸主要易受侵蚀(44%)。累计岸段仅占总海岸线的17%,其余39%的岸段相对稳定。研究结果表明,2000-2010年沿海退缩率由前期的- 1 m/年降至- 0.3 m/年。因此,加里宁格勒州整个海岸线的总体状况可以说是相对可持续的。这些变化与若干因素有关,例如受保护的海岸段的长度增加,琥珀采矿厂恢复在海滩地区倾倒砂浆,以及扩大的当地监测网络的分析数据量增加。

Abstract In this paper we describe a numerical model of transient water flow in unsaturated expansive soils and the resulting soil volume change. The unsaturated flow equation is solved in a 2D domain using a finite-volume method and an explicit time discretization scheme. Strains in the soil mass are calculated by two simplified approaches, assuming that the strain state is either 1D (in the vertical direction only) or 2D with equal strains in horizontal and vertical directions. The model is applied to two cases described in the literature, in which the strains were computed from the solution of the stress equilibrium equation. It is shown that the simplified methods give results which are reasonably close to the more complex approach based on the equilibrium equations. The proposed model can be used to predict time-varying soil shrinkage and swelling caused by natural and anthropogenic factors.
摘要本文描述了非饱和膨胀土中瞬态水流的数值模型及其引起的土体体积变化。采用有限体积法和显式时间离散化格式在二维域中求解非饱和流动方程。土体中的应变通过两种简化方法计算,假设应变状态为1D(仅在垂直方向上)或2D,水平和垂直方向上的应变相等。该模型应用于文献中描述的两种情况,其中应变是根据应力平衡方程的解计算的。结果表明,简化方法给出的结果与基于平衡方程的更复杂方法相当接近。该模型可用于预测自然和人为因素引起的时变土壤收缩和膨胀。
