AbstractDoes it take a Crypto Creature to catch public attention and raise concerns about critical water issues citizens should know and care about? The Water Services Department of Bryan Texas found the approach effective in educating citizens about the threat of cryptosporidium in drinking water. Whatever else might be said of the strategy of relying heavily on the skills of a cartoonist, the message came readily across that the crypotosporidium pathogen is mean, nasty and dangerous, a pest best shunned. Another cautionary water message that recently caught public attention was that drinking water supplies throughout the country contain pharmaceuticals.

Yield and Water Use of Barley Cultivars Compared Under an Irrigation Water Gradient at Marana, 1987Ottman, Mike; Ramage, Tom; Brown, Paul; Thacker, Gary; Ottman, Mike (College of Agriculture, University of Arizona (Tucson, AZ), 1987-09)This study was initiated to determine how barley cultivars perform outside the environment for which they were selected. Also, a comparison was made of water use by a one-irrigation barley with water use of a commercial cultivar selected for high yield conditions. Six barley cultivars bred for differing growing conditions (Westbred Gustoe and Westbred Barcott - high input; Arivat and Prato - medium input; and, Seco and 2-22-9 - low input) were compared under 12 water regimes delivered by a line -source sprinkler system. Water use of Seco, a one-irrigation barley, and Westbred Gustoe, a commercial barley, was monitored with a neutron probe. The barley cultivars bred for high, medium, and low input conditions performed best in their respective optimum water levels with the exceptions of Westbred Barcott and Prato. Westbred Barcott (high input) yielded relatively well over all water levels, and Prato (medium input), performed similar to a high input barley. Seco (low input) used slightly less water than Westbred Gustoe (high input), primarily due to its earlier maturity. The water extraction pattern with depth was similar for both cultivars due to the frequent shallow irrigations applied in this study. The water extraction pattern of Seco needs to be investigated under one- irrigation conditions.
The Arizona Water Commission's Central Arizona Project Water Allocation Model SystemBriggs, Philip C.; Arizona Water Commission, Phoenix, Arizona (Arizona-Nevada Academy of Science, 1977-04-16)The purpose and operation of the Central Arizona Project water allocation model system are described, based on a system analysis approach developed over the past 30 years into an interdisciplinary science for the study and resolution of complex technical management problems. The system utilizes mathematical and other simulation models designed for computer operations to effectively solve such problems as the CAP faces including those concerned with social and economic considerations. The model is composed of two major components: (1) a linear program designed to determine the optimal allocation of all sources of water to all demands and, (2) a hydrologic simulator capable of reflecting the impact of distribution alternatives on per-unit cost of delivery. The model, currently being use, has substantially contributed to a greater understanding of water usage potential in Arizona.
