| abstracts | The results of laboratory bedload measurements are presented. The study comprises a wide range of regular-asymmetric and irregular wave conditions in the ripple regime. A new theoretical model of the moveable bed boundary layer is used for computation of sedimentation volume in the sand trap. The theoretical results are tested against experimental data. |

| abstracts | A bearing capacity and settlement analysis of shallow foundation subjected to axial and vertical static and cyclic loads is presented. Different formulae of calculations of settlement under cyclic load are reviewed. The scope, methodology and results of model tests in both plane-strain and axi-symmetrical states are analysed. The formula of ultimate bearing capacity under static load and method of settlement calculations of foundation under cyclic load are recommended. |

| abstracts | Probabilistic linkage between significant sea level increments in 4-hourly intervals and the absolute sea level due to storm surges has been shown to exist upon comparison of the ranges of values of both quantities with the same probability of exceedance complying with the Pearson type III distribution. Hence the possible effect of the Baltic fill-up on considerable short-term surges has been eliminated and wind friction has been taken as the major forcing factor of short-term sea level growth. Finding trends in substantial sea level increments series is assumed to be equivalent to trend analysis for strong winds controlling coastal surges. The computations carried out for the period 1955-1990 at the stations Świnoujście, Ustka and Gdańsk have confirmed the existence of a statistically significant linear trend in the growth of sea level increments. EOF computations for 22 storm surge situations have been centered around numerical characteristics of atmospheric pressure fields. It can be concluded that the first EOF amplitude function a1(t) contains almost 90% of the overall variance of the atmospheric pressure fields; hence it can be a significant predictor of storm surges. An average field of atmospheric pressures controlling storm surges has also been identified, along with isolines of the first vector of local transfer functions. The behaviour of the two latter quantities confirms the linkage between onshore winds and the storm surge-induced sea level along the Polish coast. The collected data for sea level, wind and atmospheric pressure, together with results of the present analysis, provide insight into the major phenomena affecting the Polish coast and can be regarded as a sound background in formulation of the hydrodynamic input for models of coastal climate and coast evolution in decadal time scales. |

| abstracts | Determining the unfrozen water content in a frozen soil-water system as a function of temperature is still a serious problem. Existing methods involve their own sets of assumptions and approximation, and a method giving the “real" soil phase composition as a function of temperature probably does not exist. The aim of the paper is to present a method able to construct the full curve of soil phase composition during a warming run of an individual sample from –28ºC to +10ºC, including such parameters of the process as the melting point and the non-freezable water content.The method consists in determining the real heat flux function q(T) absorbed by the frozen soil sample during the warming DSC (differential scanning colorimetry) run. It is based on searching for the distribution of "heat impulses" in relation to temperature, which convoluted with the apparatus function a(T) gives a minimal deviation from the heat flux function h(T) observed. The function q(T) can easily be related to the function of unifrozen water content u(T). The latter determines the important parameters of soil freezing process: the melting (or freezing) point T0 and the content of "non-freezable" water un. Examples of computations and results are given. |

| abstracts | Simplified Eulerian-Langrangian equations are derived to simulate long wave motion in coastal regions. The principal aim of the model is to obtain a better prediction of wave run-up on mild, non necessarily planar slopes. Artificial bottom friction is implemented into the equations as well.In some very special cases, the equations could be solved analytically.Selected results of numerical model are attached herein. Special attention is focused on asymmetric shoaling wave profiles. Close agreement between analytical and numerical wave run-up predictions is obtained. Although numerical calculations concern regular waves, the random ones can be successfully treated as well. The applied Eulerian-Langrangian approach is shown to have many serious advantages (such as e.g. much simpler boundary conditions, no back-flow problems etc.) in comparison with the pure Eulerian one, at least in the considered wave run-up problem. |
