 A slight addition of moisture increases the coefficient of friction, but an excess of water acts as an unguent in diminishing the friction. The adhesion, or cohesion, may be measured by the depth to which an unsupported face of earthwork will stand before...  Waterways and irrigation - Page 7181916Full view - About this book

...; but it is an extremely varying force, depending largely upon the state in which the material is. It is increased by a moderate amount of moisture, but is diminished by excessive wetness. The cohesion of clays is considerable, and is largely increased by a small amount of moisture. A slight... | |

...also increases the coefficient of friction, but an excess of it acts as an unguent in diminishing it. It is therefore evident that any given earthwork,...will be most stable when slightly damp, and least firm when charged with water. Its stability, therefore, depends upon the ease and thoroughness with... | |
