IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Assessment of surface water quality in peel harvey region, western australia
Author : A. H. M. F. Anwar*1 and M. Wong 1
The water bodies of Peel Harvey region in Western Australia were selected to assess their surface water quality using statistical methods. Six water quality parameters such as, total phosphorus (TP), total nitrogen (TN), salinity, turbidity, pH and dissolved oxygen (DO) together with temperature for each samples from 18 monitoring sites (n=9895) were collected from the Department of Water for 2001-2009. First, normality of data was checked using box plot and histogram and found that pH and DO showed normal distribution and TP and TN showed log normal distribution respectively. Next, multivariate statistical analyses were performed and multivariate cluster dendrogram shows the spatial relationship of water quality based on the changes in nutrient characteristics of different rivers. Multivariate discriminate analysis shows that TN, TP and DO are significant in high polluted sites of the water bodies. Multivariate factor analysis showed that Serpentine river has severe pollution of TN where as Murray river has the severity of TP.
