... ABSTRACT Results of a study on the oil spreading under ice are presented. The final objective of the study was to give the estimate of oil area spilled under an ice cover in field conditions. Three different approaches of numerical simulation, laboratory test and field measurement were taken...

... proposed for assumed field conditions. Type-E drain, which has low strength of core, does not satisfy the required discharge capacity at given hydraulic gradients. All other drains satisfy the proposed criteria. INTRODUCTION Because of high water content, the bearing capacity of dredged clay is near...

... ABSTRACT In order to do numerical calculations for nonlinear wave problems, the infinite fluid region has to be truncated at a finite distance. A far field condition has to be assigned on the truncating boundary but for nonlinear cases there is no reasonably valid condition available yet...
