dc.description.abstract | This paper concerned with a new concept of modelling for kinetic energy and momentum coefficients for rough asymmetric channels. Kinetic energy coefficient (α) and momentum coefficient (β) were determined by taking a series of laboratory experiment datasets. Presently experiments were carried out in a rough (plastic mat and gravel bed on flood plain) asymmetric compound channel. In this present study, improved models have been developed to predict the accurate values of kinetic energy and momentum correction coefficients by using multiple regression analysis. Multiple regression analysis is used to predict dependent variables from a number of independent variables. Energy correction factor ( ) and momentum correction factor () are taken as dependent variable and aspect ratio ( = /h), roughness ratio (γ = / ), Reynolds number (Re) and Froude’s number (Fr), width ratio ( 1= / ), relative depth ( = ( −h)/ ) are taken as independent variable. Error analysis is performed to determine the accuracy of the present models in terms of Mean Percentage Error (MPE), Mean Absolute Percentage Error (MAPE) and Root Mean Square Error (RMSE). | en_US |
