Modelling Open Channel Flow
This webpage is for dissemination of the work on the EPSRC project "Modelling
of Open Channel Flow to Illustrate the Effects of Channel Shape and Heterogeneous
Roughness" GR/R43723/01 and the associated grant at the University
of Birmingham GR/R43716/01. The Principal Investigators on the grant were
Donald Knight (University of Birmingham), Dr
Nigel Wright (University of Nottingham) and Dr
Hervé Morvan (University of Nottingham). The Research Associates
were Dr Xiaonan Tang and Dr Mandy Crossley.
As part of the project a website was set up at the University of Birmingham
containing a large amount of data collected at Birmingham over many years
Outputs from the project that are available electronically are:
