<br />Education and Experience
<br />B.S. Civil Engineering, University of Michigan, 1953.
<br />M.S. Civil Engineering, University of Michigan, 1954.
<br />Ph.D. Hydraulics, University of California, Berkeley, 1961.
<br />US Army Corps of Engineers, Harza Engineering Company.
<br />Teaching and Research
<br />Professor Shen teaches graduate courses on erosion and sedimentation and environmental river mechanics
<br />and river engineering; and undergraduate courses in fluid mechanics or basic hydrology. His specialties are
<br />in fluvial hydraulics, environmental river mechanics, basic sediment transport, scour, numerical and
<br />physical hydraulic modeling, floods and droughts, and river basin water supply models.
<br />Development of alternative river restoration plans of Kissimmee River, Florida (with J. Harder and G.
<br />Tabios). This is the largest ecological restoration project in the US. Professor Shen has worked with stream
<br />ecologists and biologists to develop and evaluate various restoration plans based on field data, physical
<br />modelling and numerical modeling. Flow resistance through vegetation was also analyzed.
<br />Fundamental analysis of debris flows (with C.L. Chen and C. Ling, US Geological Survey) This long term
<br />experimental and analytical study investigates the behavior of granular debris flow by a conveyor- belt
<br />tilting flume and a ring -shear apparatus. Flow velocity distribution, stress distribution, and the change of
<br />debris flow profiles have been analyzed.
<br />Conjunctive use ofsurface and groundwater. This project involves constructing a mathematical model for
<br />the conjunctive use of surface and groundwater in the California Central Valley.
<br />Movements of graded sediments sizes. Most sediment transport equations are based on the transport of
<br />uniform sediment sizes while most of the streams have non - uniform sediment sizes. Professor Shen is
<br />investigating the behavior of non - uniform sediment size in different flow conditions in the laboratory and is
<br />developing a numerical model to predict the movements of non - uniform sediment sizes.
<br />Intrusion of fine sediment into gravel beds. Numerous sport fish will not spawn if the gravel is filled with
<br />fine sediments. This investigation is examining the effect of physical processes on the intrusion of fine
<br />sediment into gravel beds in the laboratory. Mathematical models are being developed to describe
<br />movements of fine sediments into gravel beds. Physical modeling of hydraulic structures
<br />Physical model tests are conducted in the hydraulic laboratory to investigate supercritical flow phenomena
<br />in steep spillways.
