USE OF HYDRAULIC MODELING FOR RIVER OIL SPILLS. 1. TRAVEL TIME COMPUTATION FOR QUICK RESPONSE

摘要

Present paper shows how a 1D hydraulic model can be used as a simple and quick tool in finding the right time and location to apply immediate response measures in case of oil pollution accidents on rivers. The necessary data to develop and calibrate the model are presented. Computed travel time from the source to each cross-section is based on mean velocity. Authors present a simple way to predict an estimate of the real oil slick leading edge travel time by knowing the computed time and the ratio of mean velocity to maximum velocity in each cross-section and given discharge.
