The function of coefficients of added mass of water

The hydrodynamic effect of the water mass reservoir on pressure face dam can be determined from function coefficient added obtained in Westergard solution. For an inclined face, design standards introduce a correction factor, which is recommended to taken into account until slope does not exceed 15 0 ; there are no such recommendations for earth dams, however, calculations seismic resistance taking also important. Theoretically, values coefficients based numerical solution Laplace equation computational domain with given boundary conditions and graphical-analytical construction grid. Thus, MATLAB environment, schemes were built different laying head range vertical flat 1:3, orthogonal grids built, reflecting equations concerning functions velocity potentials. all problems, diagrams constructed, they compared Westergaard analytical practical use work, solutions constructing presented form nomogram.
