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...

By-wash spillways for farm dams

Model studies formed a basis for investigating the hydraulics of bywash spillways for farm darns When constructed in natural earth such spillways are trapezoidal in cross section The surface of the spillway needs protection from scour and this protection is usually in the form of grass. These tests extended to variations in spillway geometry and...
