Abstract
The purpose of this article is to introduce the Harmonized Frequencies
Analysis™ (HFA), the method that considers the water cycle dynamics at
various scales, and to investigate its ability to assess the watershed development
process in order to specify the hydrological criteria for its sustainability. The
method is based on the Law of the Structural Stability of Systems and considers
river flow as an intrinsic part of the entire water dynamic system which is
responsible for temperature control.
The Humber River watershed, the lower part of which is highly urbanized and
contaminated, was assessed for sustainability at hourly, daily, monthly, and
yearly scales for the period of 1953-2006.
The quantitative increase of the base and inter components of river flow
caused by the conventionally proper storm water management in combination
with the increasing contamination and lack of vegetation resulted in alteration of
the water cycle’s functional profile, i.e. the drainage function took over the
temperature control. This is characterised by the increasing trend of instability at
all scales, pulling out tornado as the mechanism of self-stabilization at the hourly
scale.
Based on the analysis results, we concluded that HFA is the reliable tool for
the watershed sustainability assessment, which is defined as the functional
stability of the hydrological cycle within a developing spacetime.
