a sharp turn to the east, and somewhat alters its character, forming below this point a larger number of collateral channels on its left bank. A few miles below Tzaritzin, near the German colony of Sarepta, the river leaves the range of hills which, north of this, have accompanied its right bank, and no longer presents in so marked a degree that striking difference between the right and the lef...

In the past 30 years efforts to protect river beds and banks have increased significantly. The selection design of proper structural solution means finding a in accordance with construction principles, geomorphology, avoiding channel aggradation, bed scour, bank erosion, resulting structure failure significant harm stream nearby property. On other hand, should be environmentally-friendly. Hydra...

A new model to simulate the time evolution of river delta formation process is presented in Ref.. It is based on the continuity equation for water and sediment flow and a phenomenological sedimentation/ erosion law. Different delta types are reproduced using different parameters and erosion rules. The model si capable to describe the subaerial and subaqueous growth of the delta front and the fr...

Within the scope of the interdisciplinary NASRI research project (Natural and Artificial Systems for Recharge and Infiltration) dealing with river bank filtration processes at Berlin water works, a semi-technical column experiment has been ongoing since January 2003 to simulate river bank filtration. Here a 30 m long group of 6 soil columns is operated by surface water sampled from lake Tegel (...

Abstract River bank erosion, accretion and lateral channel migration are important geomorphological processes, which attract a great deal of attention river engineering scientists in many parts the world. The present study assesses morphological characteristics lower section Niger, where field data scarce difficult to access for security cost implications. Multi-date (1990, 2002 2017) Landsat i...
