Incorporating overland flow path assessments into catchment management processes

Stuart Joyce, Damian Young and Barry Carter.

Abstract

Overland flow paths are an important and fundamental component of any Stormwater drainage system. They form part of both the flood plains but more importantly the upper dendritic drainage tendrils that convey the bulk of flows to the lower topographical depressions in a catchment. Despite the fundamental importance and widespread distribution of this part of the stormwater network, there appears to be a general lack of understanding of management requirements and policy provision for overland flow paths within local and state government bodies across, Australia and New Zealand. This paper investigates and discusses some of the drivers, needs and dynamics involved in overland flow path management and provides a snap shot of the ‘state of play’ in terms of practice in Australia and a best practice example in the Auckland Region of New Zealand.
