Resistance of low cost surfaces for farm dam spillways

Third report on use of grass on farm spillways; tests on slopes 1:10 to 1:2.5 (prototype scale tests). Permissible velocities suitable for design were given.

Hydraulic characteristics of low cost surfaces for farm dam bywash spillways

As part of a program of research aimed at improving the design and construction of farm dams, the Water Research Laboratory, has with the aid of a grant from the Water Research Foundation of Australia, undertaken a study of the protection afforded to spillways by various low cost surfacing techniques. These include vegetal cover by natural...
