EXPERIMENTS OF WAVE REFLEXION ON IMPERMEABLE SLOPES

Carlos de Campos Moraes

Abstract


Results from experiments on the reflective power of smooth and rough impermea ble slopes are presented The importance of relative depth to the regular scatter dia gram of the function R=R (5o) and the need for an adequate computational wave theory through which no significant alterations are introduced in the determination of reflective power is pointed out Stokes 2nd order corrections are introduced These help find a superior value for the reflexion coefficient and destroy the mentioned regularity of the scatter diagram A regular scattering of experimental points, also of function R=R (5o) , where, however, for constant steepness, reflexion decreases when relative depth increases, is found in rough slope tests In this case, the more inclined is the slope, the greater is the influence of roughness.
