Using genetic programming to determine Chèzy resistance coefficient in corrugated channels
genetic programming Chèzy resistance coefficient corrugated channels
2009/12/4
Genetic Programming has been used to determine Chèzy resistance coefficient for full circular corrugated channels. Three corrugated plastic pipes have been experimentally studied in order to generate ...
Quantitative analysis of randomness exhibited by river channels using chaos game technique:Mississippi,Amazon,Sava and Danube case studies
Quantitative analysis river channels chaos game technique
2009/10/30
This paper presents a numerical evaluation of the randomness which can be observed in the geometry of major river channels. The method used is based upon that of generating a Sierpinski triangle via t...
A Sediment Transport Model for Straight Alluvial Channels
Sediment Transport Model Straight Alluvial Channels
2009/10/29
The paper presents a simple mathematical model for sediment transport in
straight alluvial channels. The model, which is based on physical ideas related to
those introduced by Bagnold (1954), was or...
Lateral Mixing in Channels due to Secondary Currents
Lateral Mixing Channels Secondary Currents
2009/10/27
Different mechanisms generating secondary currents in channels are presented.
It is shown by an order-of-magnitude analysis that secondary currents
of magnitude 1 % of the downstream velocity are as...
The hydraulic exponents which appear in the regime theory equations are predicted using different methods such as an empirical function, extremal energy slope, or extremal stream power. These hydrauli...
