Overview

This course provides the basic skills to carry out the hydrologic analyses and designs that are often encountered in engineering practice. Knowledge of engineering hydrology is required for the design of stormwater drainage systems, for the management of flooding and is also needed to determine how much water can be reliably obtained from water supply catchments and groundwater systems. The course provides a background to hydrological techniques used by professional engineers, including those codified in 'Australian Rainfall and Runoff-A Guide to Flood Estimation'. Students will undertake a range of hydrological analyses and computations using spreadsheets.

Course learning outcomes

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

  1. explain key hydrological processes that are important from an engineering perspective;
  2. explain how rainfall, streamflow and evapotranspiration data is measured and presented;
  3. explain how floods are statistically defined and to estimate design flood magnitude based on a frequency analysis of historical data;
  4. derive and understand how to apply design rainfalls for engineering purposes;
  5. explain loss models that are used to determine runoff from rainfall and to calculate peak runoff discharges by the Rational Method;
  6. understand and predict discharge hydrographs from catchments and the routing of flood hydrographs along stream channels and within reservoirs;
  7. calculate discharges required for the design of urban stormwater drainage systems;
  8. estimate surface water yield from a catchment and the associated reliability of a water storage;
  9. estimate the yield characteristics of groundwater aquifers.
