Design in Urban Water Infrastructure

CE 59700

Credit Hours:

3

Instructor:

Rao S. Govindaraju

Learning Objectives:

After completing this course, successful students will be able to:

Part 1

  • Analyze and design simple water distribution networks to deliver flowrates at desired pressures
  • Select and size pumps for application in simple water distribution systems

Part 2

  • Calculate flowrates and depths for open channel flow applications
  • Calculate waste water flows to determine capacities for sewer pipes
  • Analyze and design sanitary sewer systems to carry wastewater flows by gravity

Part 3

  • Compute design rainfall for hydrologic applications
  • Calculate runoff using rational method and SCS curve number method and unit hydrograph theory to manage surface water
  • Design storm sewers and detention storage volumes to manage surface water

Description:

The course deals with sources and distribution of water in urban environments, including distribution and pumping systems, analysis of sewer systems and drainage courses for the disposal of both wastewater and storm water. A review of fundamental principles including mass, momentum, and energy equations along with concepts of energy and hydraulic grade lines is provided. Equations governing water movement in pressurized pipelines are covered for both steady state analysis and transient problems through extended period simulations for use in analysis and design of water distribution systems and pump design and selection. Open channel hydraulics principles are discussed to calculate gradually varied flow profiles and learn about the Saint Venant equations for one-dimensional open channel flows. Different sources of wastewater, variability of flowrates, and types of drainage systems are described for design of sanitary sewers. Estimating design rainfall using frequency analysis is covered along with methods of runoff computation for design of storm sewer systems, determination of storage volumes for detention storage structures and level pool routing. EPANET and EPA-SWMM software packages are used for applications

Topics Covered:

Intro to Urban Hydraulics, Fluid Pressure and Forces, Basic Equations of Flow, Flow through pipes, Flow through a single pipe, Steady state analysis, transient analysis, intro to pumps, pump characteristics, pump selection, multiple pumps, open channel definitions, frictional resistance, normal and critical depths, nonuniform flows, Saint-Venant Equations, sources of wastewater flows, design considerations, sanitary sewer design, design rainfall, frequency analysis, rational method, NRCS curve number method, unit hydrographs and storm runoff, storm sewer design, design of storage structures.

Prerequisites:

A basic undergraduate course in fluid mechanics is required. Learners should have familiarity with mass, momentum, and energy equations with an ability to apply them. Ability to formulate and solve nonlinear algebraic equations will be useful. Some familiarity with numerical analysis is desirable.
