[1] We evaluate the accuracy of 1 m, LiDAR-derived DEMs of an exposed bedrock channel, and use these highresolution terrain models to calculate erosional fluxes between four levels of strath terraces dated previously with Be. Recent investigations into the timing, rates, and processes by which rivers incise their bedrock channels have greatly enhanced our understanding of landscape evolution. H...

introduction lake terraces are geomorphological evidence of climate change during quaternary. location of these terraces location in different elevation shows paleo water lake level fluctuations. investigation about urmia lake terraces was conducted by bobek (1973).he found those terraces in 45-55 meter above urmia water level on that time. according to bobek, development of lake area in paleo ...

Dismemberment of the preglacial Teays Valley system and development of the present Ohio River valley began in late Tertiary or early Pleistocene. By Illinoian time the present Ohio River was largely established in its present course, except for its headwaters above mile 114, which still flowed northward. The Illinoian glacial advance into northwestern Pennsylvania caused diversion of this porti...

A suite of fluvial terraces (T1–T6, from top to bottom of the staircase) occur along a 70 km stretch of the Tejo River in central Portugal, between the small towns of Gavião and Chamusca. Terrace correlation was based upon the following: (a) aerial photograph analysis, geomorphological mapping and field topographic survey; (b) sedimentology of the terrace deposits, namely the maximum particle s...
