Spatial Analysis of Stream Runoff Response in the Tropical River Region

D. Moliere, G. Boggs and J. Lowry
Environmental Research Institute of the Supervising Scientist and Charles Darwin University, As part of a large-scale project for the integrated data assessment and analysis of Australia’s tropical rivers, an attempt has been made to estimate the hydrological characteristics of some of the river catchments throughout the tropical rivers region of the Northern Territory. Stream runoff response, in particular, has important implications for water quality monitoring within a catchment. General diurnal patterns at stations within the Daly and the East and South Alligator river catchments were derived using long-term rainfall and streamflow data collected at each station. The general runoff response of a stream was determined from the diurnal rainfall and runoff patterns.
