Assessment of the Variability of Rates of Rise for Hydrographs on the Hawkesbury Nepean River

Webb, McKeown & Associates were engaged by the SES to undertake an analysis of possible rates f rise and their probabilities at Penrith and Windsor, particularly for design floods ranging from the 1% AEP event to the 0.2% AEP event. This report outlines the analysis taken and its findings.

The Study presents information concerning probabilities of potential rates-of-rise of for the Hawkesbury Nepean River System. Objectives include to:

  • Investigate if spatial patterns had a significant influence on the rate of rise.
  • Determine whether the standard design method introduces any significant bias and if so to quantify this bias, and
  • determine any bias introduced by the design temporal patterns
