Abstract
The significance of surface and sub-surface geology in shaping ecosystems and local hydrology is not fully understood. Mapping palaeochannels and subsequently relating their distribution with vegetation types and surface/subsurface hydrology may provide further insight into the relationship between geological processes and local-scale ecosystem response. There are various approaches to mapping palaeochannels including optical and microwave remote sensing, sub-surface sampling, groundpenetrating radar (GPR), aerial laser survey (ALS) derived elevation model, and visual observations in the field. This study explores the effectiveness of remote sensing based approaches to map spatial distribution and characteristics of preserved Late Quaternary palaeochannels, associated vegetation and regional geologic structure. This study identifies the use of multi-temporal optical remote sensing images, the use of geomorphometric parameters derived from high-resolution elevation model, and visual field observations to map surface expressions of palaeochannels. Finally, the study compares the possible palaeochannels mapped from these three approaches
