Final Exam Flashcards
Grain Size Analysis is used for…
Soil classification, filling embankments, determining use of material
Darcy’s Law
K= Cd^2 pg/ u
Q= KA(delta H/L)
Shepherd Equation
K=a(d10)^b
Intrinsic Permeability
k= Cd^2
What is the difference between hydraulic conductivity and intrinsic permeability?
HC: a function of both fluids
IP: a function of only media properties
Laboratory Method of measuring hydraulic conductivity
Constant head permeameter
Constant head permeameter equation
K=VL/Ath
Falling head permeameter
Water deposited into tube through funnel, connected to permeameter, measure time it takes to empty tube
Falling head equation
K= (dt^2 L)/dc^2 t) (ln(h0/h)
dt= diameter of tube
dc= diameter of column
L= sample length
h0= initial height
h=height
Homogeneity
material in an aquifer is all the same
