Digital Elevation Models (DEMs) are used to estimate different morphologies, analysis of river profile, delineating drainage basin and drainage pattern associated with lithological and structural changes. The study area is Maroon River located in Khuzestan Province, Iran. In this study geomorphometric analysis based on DEM carried out to understand Maroon river uplift rate and tectonic- erosion...

The marginal regeneration process responsible for foam film drainage is revisited. It shown that a horizontal, micron thick, in contact with meniscus destabilizes and patches of thinner grow along the meniscus, forming very regular pattern.
