[P02-11] Development of estimation method for energy loss in non uniform flow by combining physical model and statistical model
Keywords:energy Loss, sparse modeling
In oder to accurately determine energy loss in non uniform flow using mathematical model of open channel flow, velocities and depth of water must be simultaneously measured with high resolution. However, energy loss in non uniform flow (IeN(x)) which has spatial distribution, has been calculated generally using the Manning formula as energy Loss in uniform flows. In this study, to estimate IeN(x), we investigate a new solution method combining physical model analysis and inverse analysis. We performed a simple 1-dimensional numerical analysis which estimate IeN(x)’s energy loss coefficient to confirm the applicability.
