Hydrologic changes and human interventions gradually change the river course. Geomorphology or study of rivers’

behavior seeks to determine the action and the reaction or the behavior of rivers in various conditions. The...

A method called Merged Perpendicular Method (M.P.M.)has been developed to compute the distribution of boundary shear stress across irregular straight channels. In a concave angle of a cross section, computed shear stress ...

The boundary shear stress is one of the most important parameters both for practical developments and for fundamental studies in open channel hydraulics and fluid mechanics. The authors have presented a fairly reliable ...

One of the most important subjects in river engineering is design of stable channel section. Various cross sectional shape equations have been proposed to describe the bank profiles of straight threshold channels. In this paper, a new method has...

In this paper, 13 models are compared against 6 sets of laboratory data for computation of bank profile of the stable channel. The applied models are Glover and Florey (GFM), Parker (PAM), Ikeda (IKM), Pizzuto (PIM), Diplas ...

Gorgan River, with its length of 325 km is one of the largest rivers in the Caspian Sea basin. It crosses sensitive erosion reaches and finally joining the Caspian Sea from the Eastern side. The Gorgan River morphology has changed in the last...

For ungauged catchments where there is no flow data it is always more difficult to find a method to obtain acceptable results of future flow prediction. In recent years the technique of Artificial Neural Networks (ANN) has ...
