From the Proceedings of the 1979 Meetings of the Arizona Section - American Water Resources Assn. and the Hydrology Section - Arizona - Nevada Academy of Science - April 13,1979, Tempe, Arizona / Scientists and industrialists are now seeking from their reclamation brethren an explanation of the new criteria and standards which will enable all of us to recognize a visually reclaimed site when we see one. To do so may require more of the viewer than the ability to perceive visually. One must understand the larger game in which reclamation is played.

From the Proceedings of the 1979 Meetings of the Arizona Section - American Water Resources Assn. and the Hydrology Section - Arizona - Nevada Academy of Science - April 13,1979, Tempe, Arizona / Land use planning, within the context of socio-economic development, is characterized by many conflicting objectives. This paper defines ojectives for the San Tiburcio watershed in northern Mexico. A mixed multiobjective programming model is developed. The model serves as an aid to a group of decision makers in choosing a "satisficing" feasible set of non-mutually exclusive land use alternatives. The paper concludes with a discussion of possible solution techniques.

From the Proceedings of the 1979 Meetings of the Arizona Section - American Water Resources Assn. and the Hydrology Section - Arizona - Nevada Academy of Science - April 13,1979, Tempe, Arizona / The impact of a selected set of socioeconomic variables on residential water consumption per household is examined using a combined cross-section time-series analysis by census tract for Tucson, Arizona for 1974, 1975, 1976 and 1977. The estimated income elasticity of demand for water is .23, which means that a 10-percent increase in income produces a 2.3 percent increase in water use. Additionally, the number of persons per household and the percent of households with head age 65 or more also are shown to have a strong positive relationship to water use. New residential units are shown to have a strong tendency to utilize less water than older units, presumable because of a shift away from water using yards. Both Black and Spanish-surnamed dominated areas tend to consume a lower than expected amount of water for their income and family size characteristics, but the coefficients on these variables are not sufficiently strong to accept this relationship.
