洪水時における貯水池の成層破壊について

Abstract

De-stratification resulting from flood flows gives a significant influence on stored watersin qualitative and quantitative aspect. In this study, the de-stratification process is inves-tigated by making use of field data observed continuously and the criterion for themacroscaled stability of the stratified flow is discussed in terms of hydrologic and hydr-aulic parameters. A mathematical model including the momentum equation as an exte-nsion of traditional model is presented to predict hydraulic behaviours of stored watersand to simulate the de-stratification process. The results predicted by the presented modelare compared with observations and estimated in view of hydraulic aspect.
