Looking for information on the Gila River? This site brings together a large dataset of the physical characteristics of the river drawn from a number of public records sources. A study surveys the patterns of the basic processes and inter-relates them. A single randomly recurring event in the chemistry at a single site serves as a focal point to compare with normal seasonal behaviour. The various patterns and terms used come to resonate with one another, creating a comprehensive, coherent, functional picture of the river system.
