Definition

• Hydraulic Engineering is a sub-discipline of
  Civil Engineering concerned with the flow and
  conveyance of fluids, principally water. This
  area of engineering is intimately related to the
  design of bridges, dams, channels, canals, and
  levess and to both sanitary and environmental
  engineering.
• Common topics for design of Hydraulic Engineers
  are Hydraulic Structures like dams, levees,
  culverts Water Distribution networks, water
  collection networks, storm water management,
  sediment transport and various other topics
  related to Transportation Engineering and
  Geotechnical Engineering

Why Study Hydraulic Engineering?
Tennessee has 525 community public water supply
systems
RIVER or RESERVOIR
Center Hill Dam
Center Hill Reservoir
Intake Conduit
Storage

But why care about water?Too little or Too much
is a problem

Real-world Application of Hydraulic Engineering
Two Scenarios
1. Pioneers settling in the river banks of
Memphis in the 1700s
2. Rebuilding New Orleans after Katrina

Future Trends Challenges(How can CEE3420 Help
get a job?)
Phase II NPDES Permitting urban runoff,
cities construction sites gt 1 acre
Tennessee Development Stats 525 community public
water supply systems development rate 7th in
nation 80,400 acres/year Problems Greater water
demand Increased pollution from urban
runoff Solutions Water conservation/efficiency
Better site design Stormwater system
retrofitting Stormwater Utilities BMP technologies
