Based on the analysis of contamination of hydrosystem headraces with floating materials, we developed a system of protective facilities, including protective booms, abutments and bottom mats, guiding booms. To justify the operation of the developed facilities, automated calculations of the listed guiding and retaining facilities were performed. The main attention was paid to the experimental study of the facilities. As a result of the experimental studies, we determined values of forces in a ground sill, depending...

The paper examines the results of a series of field observations carried out on the Atlantic coasts of France polluted by heavy fuel oil spilled due the accident of the tanker ?Erika? in December 1999. The aim of these observations is to determine the rates of the spilled fuel oil natural degradation and to consider their relationship with principal environmental factors. It is a part of a larger-scale research being performed on geographically different oiled seacoasts in France, Spain, and Russia. In France, eig...
