The analysis of the interrelations between the hydraulic, morphometric and load variables of the River Marshaw Wyre, Lancashire, England.

Abstract

This investigation is a quantitative geomorphologic examination of the relationships that
exist between the morphometric, hydraulic and load variables of the River Marshaw
Wyre. A wide variety of 11 variables were measured at ten locations along the stream,
downstream of the source, the variables were then analysed using a combination of scatter
graphs and persons product moment coefficient correlation to determine whether there are
any relationships between the variables.
There were many significant correlations which were found between the variables and
most of the interrelations found in this investigation had been found in previous research.
It seems that this study has shown that discharge vs distance downstream, bedload size vs
distance downstream and velocity vs distance downstream are some of the most
significant relationships within the River Marshaw Wyre. Other researchers have also
shown other significance relationships but these were not found in this investigation such
as depth vs distance downstream. It was thought that the distance of the Marshaw Wyre
was too short for any real difference in the landscape for depth to have any interrelations
with other variables in the river channel.
