WATER
THROUGH
SOILS
,TOPIC OUTLINES
a) INTRODUCTION, DEFINITION &
TERMS
b) DETERMINATION OF THE
COEFFICIENT OF PERMEABILITY
c) SEEPAGE & FLOWNET
.
, SUB TOPIC 2a
INTRODUCTION, TERMS
& DEFINITION
• Concept of heads, hydraulic gradient, Bernoulli’s
equation, and Darcy’s law
• Concept of permeability
• Determination of the coefficient of permeability
LESSON
At the end of this lecture the students
OUTCOMES
would be able to:
1. Define the concept of pressure head and hydraulic
gradient using the Bernoulli equation.
2. Understand the definition of permeability and 1-D flow of
water through the soil using Darcy Law.
3. Determine the coefficient of Permeability (k) for the
laboratory test. (Constant head test and Falling head test)
, Water found in the subsurface in
GROUND the saturated zone below the water
table.
