The qualitative indications of water is no less important than its Quantification  indications, as the abundance of water is not enough in case of its bad quality, and a better example on this is the water of seas and oceans, as despite the abundance of sea and ocean water, yet it is unsuitable for various uses, as its salinity limits its usability, as well as the water quality has a disparate importance as to its uses, which is shown through the study of physical properties of a group of Al-Qadisiya Governorate rivers.


          In this research, (36) samples of water were taken, (18) samples in April represented the theoretical spring season and (18) samples in September represented the theoretical autumn season, three samples for each season and each main river in the study area were represented at the beginning, middle and end of the course in order to study the physical properties of the selected rivers in the study area.
