Journal Title Issue Volume Edition Pages Book Title Editors ADWR Report Modeling Report # Map Number of Pages 82 Summary This thesis focuses on a one-mile stretch of the Santa Cruz River located between Tumacacori and where the Josephine Canyon enters the Santa Cruz River. The analysis takes into account conditions along this stretch of the river between 1965 and 1980. The goal of the thesis is to document and quantify how vegetation affects hydraulic change, and consequently its effect on flood events and flood plain management. This section of the river makes a unique study site because it has been converted from an ephemeral stream to that of intermittent effluent discharge flow. This site was identified for the intensive study as it had been classified as hydrologically complex in a flood insurance study and also because the Soil Conservation Service had previously examined the tract of the river, and lastly because low-level aerial photography was available allowing for decade-long observation of the site. The change in water availability at the site, from intermittent to ephemeral, effluent-fed, has changed the vegetation along the river, creating a much “rougher” channel. This new roughness has consequences upon the absorption capabilities of the river, thus affecting flood events. The author’s goal is to show that as a result of effluent flows and increasing vegetation, the channel at the study site has become rougher, or less capable of handling flood events, and thus the flood plain must be redrawn. The author provides his analysis of the new 10-100 year flood event possibilities, and how 100 year flood plain should be redesigned. One problematic part of the document is that the author cites the nearby site (relative to the study location) of the Santa Gertrudis Crossing of the river as 3555 feet above sea level. This elevation appears to be incorrect, as the river channel at Tumacacori is less than 3300 feet. Author provided abstract The federal flood insurance program as authorized by legislation in 1968 and 1973 provides federally subsidized flood insurance to residents of communities which participate in an approved flood plain management program. As a vital initial step in this program, a reasonable flood boundary must be defined for legal enforcement. Methods of definition have been developed on streams in humid parts of the United States where stream channels and flood plains remain more nearly stable than in the southwest. These methods are now standard in all parts of the country whether or not they are hydrologically sound for any given area. Results obtained from applying techniques developed in mesic climates to arid lands hydrology imply stable conditions in systems which are often hydraulically unstable.

Journal Title Ecological Indicators Issue 3 Volume 2 Edition Pages 93-117 Book Title Editors ADWR Report Modeling Report # Map Number of Pages 24 Summary This paper establishes baseline data on benthic macroinvertebrate communities along the Santa Cruz River between the international border with Mexico and the Pima County line. Samples were collected four times from 9 different sites during a one-year period. The specific collection dates are not given, but they are noted as having occurred during May, August, December, and March in an effort to sample different seasonal conditions along the river. According to the authors, “…these (effluent-fed) streams support aquatic communities whose attributes can be used to establish biological criteria to classify the water body as health or impaired.” This possibility becomes even more important when one considers that the most common biological criterion used, in accordance with United States Environmental Protection Agency (USEPA) guidelines, is the status of the benthic macroinvertebrate community. The authors do not attempt to qualify the state of the aquatic system, in accordance with USEPA standards. Rather, they have created a baseline survey of the benthic communities as well as different water chemistry indicators which can subsequently used to classify the water quality. Author provided abstract This study provides an assessment of the ecological conditions of a 46-km effluent-dominated stream section of the Santa Cruz River in the vicinity of the International Waste Water Treatment Plant, Nogales, AZ. We associated changes in the structure of the macroinvertebrate community to natural and anthropogenic chemical and physical variables using multivariate analysis. The analysis shows that biological criteria for effluent-dominated streams can be established using macroinvertebrate community attributes only with an understanding of the contribution of three classes of variables on the community structure: (1) low flow hydrological discharge as affected by groundwater withdrawals, treatment plant discharge, and subsurface geomorphology; (2) chemical composition of the treatment plant discharge and natural dilution; and (3) naturally produced floods resulting from seasonality of precipitation.

Journal Title Issue Volume Edition Pages Book Title Editors ADWR Report Modeling Report # Map Number of Pages 125 Summary Abstract provided by author/library, a full version of this thesis must be ordered from the U of A library) Author provided abstract A two-phase study of the Upper Santa Cruz River Basin consisting of a hydrologic assessment and the application of a computer model to the area is presented. Groundwater occurs in Older and Younger Alluvium units, is held under unconfined conditions, and is of good quality. The Finite-Difference Three- Dimensional Groundwater Flow Model (MODFLOW) is applied to the study area in order to simulate the hydrologic system. A water budget and conceptual model is developed to aid in model input and calibration. A steady-state analysis for the system is performed for 1965 in order to calibrate model parameters and produce initial conditions for the transient analysis. A transient analysis is performed to verify model response over the period 1965-1980 in which stresses to the system are changing. Model-produced trends and water levels are consistent with observed data, indicating the model's utility for predictive analysis of the system.
