3. STABILITY OF SLOPES
3.1
General
An ability to assess the stability of natural and man-made slopes is one of the most
important roles played by the geotechnical engineer. Wherever slopes are found, be they
permanent or temporary, there is always a dange

Soil Nails
The topic of soil nails is often considered in more advanced
subjects on geotechnical engineering such as would be
encountered when considering earth retaining structures
and/or soil stabilisation.

Worked example
A soil profile consists of 5m of medium dense sand, overlying a 7m thick layer of dense gravel,
over a very deep formation of stiff clay. The ground water table

CHAPTER 3
Working With HEC-RAS - An Overview
HEC-RAS is an integrated package of hydraulic analysis programs, in which
the user interacts with the system through the use of a Graphical User
Interface (GUI). The

CHAPTER 4
Example Application
This chapter provides an example application of how to perform steady flow
water surface profile calculations with HEC-RAS. The user is taken through
a step-by-step procedure of how to enter data

Seepage - Worked example
One side of a wide cofferdam is formed by a sheet pile wall driven 10m into a layer of sand
which is 20m deep and overlies an impervious rock. The sand has a coefficient of
permeability of 1

2. PERMEABILITY AND SEEPAGE
2.1
General
This section will consider the steady state flow of water in soils. Steady state conditions
mean that flow rates, soil volume and soil stresses are constant throughout. Non-steady
state or transient conditions are a

Stability of Slopes
This section will consider the stability of slopes in soils.
The slopes we will be considering include natural slopes formed
by the action of many processes including water, wind, waves,
weatherin

On completion of this subject the student is expected to:
Interpret a design problem, develop criteria (technical, economic and
environmental) to evaluate soluti

1. PORE-WATER PRESSURES AND EFFECTIVE STRESS
1.1
General
The influence of pore-water, particularly pore-water pressure, is of great importance in
soil engineering and must be thoroughly understood if the behaviour of a soil is to be
understood.
Consider a

Q3: Solution:
Flow is critical on the bump.
Therefore flow per unit with is
Therefore flow is
Q4: Solution:
Because the jump is small the flow must be only just supercritical.
Therefore the speed of the flow is
Therefore the flow is
Q5: Solution:
Upstream

3. Water flows along a 2m wide channel of rectangular cross section. A short distance downstream
(short compared to the frictional length scale) the flow passes over a long bump extending across the
full width of the channel. What is the flow in the chann

The aim of this experiment is to examine an open channel flow downstream of a broad crested weir in which
super-critical gradually-varied flow leads to the formation of a hydraulic jump as a re
