Abstract

The quantitative analysis of a drainage system is essential in understanding the hydrological behavior of the catchment. The present study was carried out in a drainage basin (Oratunga basin) in the Central Flinders Ranges, South Australia. GIS techniques were used to assess critical morphometric characteristics of the dendritic to sub-dendritic drainage pattern. The analysis has shown that the total number and length of stream segments decreases from first order to fifth order streams. The bifurcation ratio (Rb) between different successive orders varies and the shape parameters indicate the elongated shape of the basin. The compilation of the different parameters reveals that the groundwateris mainly controlled by geomorphology, slope, geology, and drainage density. Based on these factors groundwater potential of the basin was classified into good, moderate and low zones. The study reveals that quantitative analysis based on GIS techniques and available data is a useful tool for geohydrological studies. Future research will focus broaden the study area in the Flinders Ranges and similar semi-arid areas.
