Remotely detecting changes in landforms has long relied upon the interpretation of aerial and satellite images... More recently, data produced by photogrammetry and Light Detection and Ranging (LiDAR) models have become commonplace for those involved in geographical analysis - engineers, hydrologists, landscape architects and archaeologists...
In new research published this week in the journal Earth Surface Processes and Landforms, Cambridge archaeologists present a new algorithm, Multi-Scale Relief Model (MSRM), which is able to extract micro-topographic information at a variety of scales employing micro-, meso- and large-scale digital surface (DSM) and digital terrain (DTM) models...
The TwoRains multitemporal remote sensing approach has had an important impact as it was able to find and accurately trace more than 8,000km of relict water courses; the image of which has been selected as the cover image of this year's Cambridge Science Festival (see image above).
However, the authors were conscious that many ancient rivers were not being found... nderstanding how the Indus civilisation accessed and managed their water resources is at the heart of the TwoRains Project.

A composite image of vegetation indices in Northwest India created from 1254 images reveals a complex palaeoriver network comprised of more than 8000km of palaeochannels. The new MSRM algorithm will contribute to mapping the complete ancient palaeoriver network of northwest India and to a better understanding of how the Indus Civilisation operated c. 2600-1900 BC.

Don’t tell the Hoffmans - they’ll pack up and head out on another quixotic gold rush.
Thar’s gold in them thar paleochannels!
It's just NW of Lipan.
