Experience with Hydraulic and
Mechanical Properties of Fractured Rock
In his geotechnical work on dams, shafts and tunnels, and especially
of fluid -flow problems of civil, mining, petroleum and environmental
engineering, Dr. Snow featured properties of fracture systems in hard
rocks. He is qualified in rock mechanics as in hydrology, since the two
fields have been applied simultaneoulsly in many of his consulting jobs.
