f Drainage Network Response to Geological Structures: A Case Study of Joya Mair Oil Field (Pakistan)

The Joya Mair Oilfield is part of the folded and imbricated Himalayan thrust sheet in Pakistan. Its drainage networks with<br>transverse streams intersect different geological structures at their highest structural position. This dynamic interaction can be<br>studied by their mutual superposition and different quantitative behaviours. We use drainage network extracted from Shuttle<br>Radar Topographic Mission (SRTM 90 m) digital elevation data. We use digital image processing techniques on SRTM data<br>and already published maps to prepare lineaments database of the area. The stream power law under steady state condition can<br>be used to calculate incision rates.
