Abstract

The AA. examine the Shuttle Radar Topography Mission (STRM) data for 3 catchments in Australia over a range of climates, geology and resultant geomorphology. The SRTM data are compared with high resolution digital elevation models. The AA. use basic hydrological and geomorphological statistics and descriptors such as the area-slope relationship, cumulative area distribution and hypsometric curve, along with Strahler and networking statistics. Care must be used for quantitative assessment of catchment hydrology and geomorphology, as in all cases SRTM-derived catchment area is incorrect and smaller digital elevation grid sizes are required for accurate catchment-wide assessment
