Application of Energy Approach to Estimating Scour Depth
Many permanent spillway tunnels of high earth-rock dams are rebuilt from their diversion tunnels. Scour problem is focused because of their high water head and velocity. Energy Approach is a new method to Estimating Scour and is used here to estimate the depth of scour downstream of 1 spillway tunnel of Zipingpu Project. The method is illustrated working fine by comparing its results with data ...
متن کاملPredicting Bridge Pier Scour Depth with SVM
Prediction of maximum local scour is necessary for the safety and economical design of the bridges. A number of equations have been developed over the years to predict local scour depth using laboratory data and a few pier equations have also been proposed using field data. Most of these equations are empirical in nature as indicated by the past publications. In this paper attempts have been ma...
متن کاملVortex Lattice Model for Mine Scour and Burial
1) Identify leading order processes; 2) formulate the model and write the computer code; 3) initialize and calibrate the model using archival data; 4) validate the model in a contemporary field experiment with modern mines of various shapes; 5) conduct numerical experiments with the model to determine the relative strength of various scour and burial mechanisms, and the sensitivity of those mec...
متن کاملPrediction of Scour Depth around Pile Group Using Ann
Prediction of the scour around a group of pile in the field exposed to oscillatory waves is very important for many offshore structure and coastal engineering projects. Conventional predictive formulas for the geometric properties of scour hole, however, are not able to provide sufficiently accurate results. In this paper the ANNs approach is used to predict the scour depth around pile group us...
