Prediction of Discharge in Straight Compound Channels using Conventional and Soft Computing Tools
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 8
Abstract
Proper assessment of discharge capacity of a river is needed for design, operation and maintenance of channels. Estimation of stream flows in the compound open channel by numerical approach is very complex as it involves inputs from a good number of parameters. During high floods and where gauging stations are not located, it becomes very challenging to predict the discharge at these locations and the situation. Measurement of discharge at this stage becomes risky and the quantum of flow estimated are based on extrapolation of Gauge – discharge curves that are mostly inaccurate. Actual discharge is always different from the calculated values. Tools such as soft computing techniques are used to resolve the real world problems. Also the actual data collected from river need to be mapped with the experimental results. This mapping can reveal the suitability of the techniques used in prediction as well for justification of the experimental setup done with good financial investments. Three different data sets are used to compare the best suited soft computing technique for discharge predictions.
