Abstract

      In Vietnam, known methods of calculating cross drainage works of highways, taking into consideration the phenomenon of water accumulation in front of work, not the general shape for all flood flows. Therefore, in this article the author propose additional calculations of  water accumulation and water regulation in front of cross drainage works with the flood lacking shape but usually occurs with terrain conditions and the climate in Vietnam.
