Indicative Syllabus

Indicative Syllabus

  1. Principles of open channel flow for steady uniform flow , relationship between hydraulic gradient and channel slope in an open channel. Understand the limitations of the Chezy Equation and the Manning Formula. Determine flow rates and depths in rectangular, trapezoidal and circular channel and pipe sections.
  2. Determine the optimum geometry of rectangular and trapezoidal channels. Flow measurement in open channels using non critical flow devices, vee-notch, rectangular and Sutro weirs.
  3. The hydrological cycle. Meteorological data. Evaporation. Transpiration. Infiltration. Percolation. Surface runoff. Catchment characteristics. Rainfall/runoff correlation. Flow rating curves. Volume and duration of runoff.
  4. Hyetographs, catchment lag, hydrograph analysis. Components of a natural hydrograph. Baseflow and baseflow separation.
  5. Unit hydrograph. Derivation of the unit hydrograph. Introduction to the instantaneous unit hydrograph. synthetic unit hydrographs. Flow rate prediction using unit hydrographs.


 Indicative Practicals/Projects  

  1. Catchment survey to be commenced in week one. Field work inclusive of hydraulic, bathymetric and topographical survey to be carried out at two sites. Measured flow rates to be compared with OPW data. Stage curves to be produced for each site. Flow duration curves to be produced for each river catchment.
  2. Determine Mannings “n” and Chezy’s “c” for a rough and smooth channel bed.
  3. Design sewer and surface water pipeline using HRL charts and the Manning formula.
  4. Calibration of sharp crested thin plate weirs (vee-notch and rectangular).
  5. Construct a hydrograph for a storm of known intensity and duration. Estimate the storm loss. Separate the base flow.
  6. Construct a unit hydrograph for a given rainfall intensity and duration. Use data to predict flow rate for other rainfall event. Verify predicted flow rate in laboratory.
