abstracts | The paper concerns the problem of calculation of the maximum horizontal forces that a floating ice cover can exert on isolated, vertical-walled, engineering structures. The analysis is carried out on the assumption that the largest possible force which can occur in a floating ice plate is determined by the elastic buckling failure mechanism. Hence, the buckling loads of a semi-infinite, wedge-shaped in-plane, thin elastic plate resting on a liquid base and pressing against a rigid structure of a limited width, are evaluated. The problem is solved by applying the finite-element method. The results of numerical calculations illustrate the variation of the buckling force with the thickness of ice, the width of the structure, the angle defining the in-plane shape of the plate, and the type of boundary conditions at the ice–structure contact zone. The comparison of the results obtained in this work with those given by approximate analytic estimates available in literature, has shown that the latter considerably overestimate the bearing capacity of ice, therefore new relations are proposed in this paper. |

abstracts | A method of the numerical solution of a 2-D linear advection equation is proposed. In the solution, the modified finite element method and directional splitting technique is used. For the time integration the two-step differential scheme is used. Two weighting parameters introduced into the schemes determine the accuracy and stability of the solution. Numerical diffusion and dispersion tensors are derived for the pure advection equation solved using the proposed method. They enable the explanation of numerical properties and applicability of this scheme. The proposed scheme is of third-order accuracy and is adaptive, allowing for simultaneous elimination of numerical diffusion and dispersion from the solution of a 2-D advection equation. |

abstracts | The results of physical modelling of water flow in `Wild River' type slide are presented. The hydraulic investigation concerns the water slide being a component of `Świat Wodny Nemo' water-pool complex in Sopot. The laboratory tests were carried out on a model of the slide installed in the Laboratory of Hydro and Environmental Engineering of the Gdańsk University of Technology. Generally, the water flow observed in the open channel and reservoir system can be classified as steady and rapidly varied. The large number of local, hydraulic effects was observed along the whole slide track due to strongly varying bottom slopes and curvatures of channel bends. |

abstracts | An analysis is given of standing water waves of finite amplitude growing in time. In the model considered, a piston-type wave maker generates the waves in a rectangular fluid domain. The frequency of the generation corresponds to water waves of lengths equal to double length of the fluid domain. In this way the case of resonance the obtained and the amplitude of the generated standing wave grew in time. The analysis has been confined to the second order approximation expressed in the material variables. Theoretical results have been compared with experimental data. |

abstracts | The paper presents the analytical solution to the problem of groundwater flow through observation well. Assumptions enabling the formulation of the problem using classical theory of seepage are specified. The solution was derived from the variable separation method. Obtained results confirm the outcomes of investigations, conducted on physical models, published by other researchers. Numerical modelling may be useful to obtain solution of the poblem for more complicated case e.g. complex geometry, other boundary conditions, anisotropy of medium. An example of calculation applying finite element method is given. |
