AS Materials NotesAS Materials Notes• Integrity evaluation of auxiliary spillway

Describe materials exposed to erosive attack Geologic profile through spillway Spillway centerline profile?? Erosion occurs at weakest materials Input weakest geologic profile in spillway

• Material Description only for labeling Be descriptive “CL1, CH2, Limestone” are better than 1, 2

39

PI - Dry Density - % ClayPI - Dry Density - % Clay

• PI for time of phase 1 (surface-vegetation) failure

• PI most important for materials initially exposed at spillway surface

• Dry density and percent clay determe the erosion rate coefficient of downcutting for concentrated flow and headcuts in cohesive materials

• Use either % clay or detach rate (jet erosion test)

Rep Diameter & KRep Diameter & Khh

• Size of material detached as single unit

Large materials -

Governs computed threshold where surface shear

detaches material in concentrated flow or headcut

downcutting

• Headcut erodibility index (Kh) governs threshold and rate for headcut advance
