Hydrodynamic traps are characterized by low velocity of fluid filtrations in regions of relativily low pressure potentials and by not-horizontal contacts of oil and water or gas and water. Typical hydrodynamic traps are also those, which are to find
in the flanks of anticlines and monoclines or in structurally noses of terraces, holding by hydrodynamic forces. The research of such traps is only possible by use of a complex of special geological and hydrodynamical methods. Of course, here it is necessary
to combinated these methods with those for study of oil and gas reservoirs by petroleum engineering. In future the hydrodynamic traps will be have a great lot of oil and gas potential for the humanity. When the use of oil and gas in all countries is growing
in the same way how in past, so the hydrodynamic traps in far future can be to obtain the first place in the discovery of oil and gas fields.

This paper focuses on the hydrodynamic behaviour of bioclastic sand sampled from the cheniers of Mont-Saint-Michel bay (France). The dual behaviour of the shell fragments (low settling velocity, good resistance to unidirectional flow) should
The present study adresses to the questions how the shoreface-connected ridges along the central part of the Dutch coast were formed and what their behaviour is under the present hydrodynamic conditions. The study is based on field observations
and model computations. The field observations focus on the present hydrodynamic and sediment transport processes, on the resulting morphological and sedimentological response, and on the geologic evolution of the ridges. - (AGD)

The AA. implemented groundwater inflow to the one-dimensional hydrodynamic simulation of lake water temperatures to improve the reproduction of the real water temperatures by the simulation results for Lake Ammersee, Southern Germany. As the hydro
-geological conditions at Lake Ammersee have not yet been finally clarified, they created simulation scenarios for the hydrodynamic modeling with various characteristics of sub-terrestrial inflow. Analysis of the simulation results for each scenario revealed
of simulation results to real conditions for almost all depths and seasons. This implies that the hydrodynamic simulation of water temperatures at Lake Ammersee, including subsurface inflow, provides reliable results.
The soil surface characteristics of vegetation stripes in Northern Mexico and their influences on the system hydrodynamics. An experimental approach
To characterise the spatial variability of the soil surface features and their role in the hydrodynamics of the vegetation stripes, the AA. first described them along a transect perpendicular to the main axis of a stripe together with the detailed

The main objective of this study is to provide a concept to relate quantitatively floodplain characteristics, hydrodynamic and sedimentological variables with spatial patterns of overbank sedimentation at the scale of a river reach of several
kilometres. For this purpose, a GIS-based sedimentation model was developed which uses two-dimensional water flow patterns simulated by a hydrodynamic model as a basis. The model was tested in a case study for 3 representative sections of the embanked

and changed run-off characteristics. The relationship between the estuaries and the estuary mouth forms the basis of the interpretation presented. Disruption of the tidal regime has led to substantial hydrodynamic and morphological changes, triggering complex
