Abstract:

This paper is concerned with restoring the quality of water in some portions of the San Pedro River. There are high concentrations of bacteria in some parts of the San Pedro River. Our aim is to find ways of improving the situation. Specifically, there are two objectives in the study. The first one attempts to identify the possible sources of the bacterial contamination and assess its trends within the watershed. The second objective is to determine appropriate methods of restoring the water quality. The main water quality problem is nonpoint source pollution, which enters the stream and moves

Abstract:

A finite element groundwater flow model was used to support a hydrologic assessment for a study area in the Lower San Pedro River Basin which contains the Bingham Cienega. Consolidated sedimentary rocks associated with an extension of the Catalina Core Complex truncate the floodplain aquifer system in the study area. The elevated water table produced by this "hardrock" results in spring discharge at the cienega and a locally gaining reach of the San Pedro River. The steady -state model suggests that recharge (and discharge) components for the floodplain aquifer sum to 3.10 cfs. Mountain

This report is in two parts. The first part covers the ecological processes pertinent to the restoration of Bingham Cienega. The second part presents a subregional groundwater flow model for analyzing the water budget, stream and spring behavior, and water table configuration. Because of the sparsity of ecological and hydrologic data, both parts must be considered as preliminary studies.

Abstract:

A potential for conflict exists over water management and allocation in the Upper San Pedro River Basin. Competing demands for limited water supplies have resulted in concerns about the depletion of the ground-water supplies, reductions in stream flow, and downstream obligations associated with the Gila River Adjudication. A network flow model is an effective tool for analyzing the nature of these water conflicts and evaluating how the introduction of new management strategies can ameliorate the problems. Analysis of water management reveals that concerns about the water problems are valid. Ir

Abstract:

Streams and groundwaters interact in distinctly different ways during flood versus base flow periods. Recent research in the Upper San Pedro River using isotopic and chemical data shows that (1) near-stream, or 'riparian,' groundwater recharged during high streamflow periods is a major contributor to streamflow for the rest of the year, and (2) the amount of riparian groundwater derived from this flood recharge can vary widely (10-90%) along the river. Riparian groundwater in gaining reaches is almost entirely basin groundwater, whereas losing reaches are dominated by prior streamflow.This des

A study in the 1990s quantified gray hawk diet and habitat use in this area, and found that gray hawks hunt primarily in mesquite, eat mostly lizards, and that their productivity is positively correlated with the percentage of mesquite in their territories.

The hydrologic system of the Upper San Pedro River Basin is threatened with the depletion of surface water flow in the San Pedro River.

Abstract:

Landscapes are changing environments. Conservation of the amenities associated with landscapes must take into account the tendency of a landscape to change over time. Change is considered to be influenced by both cultural land use practices and natural resource processes which act on the landscape. A technique is developed which demonstrates an approach to measure the stability of landscapes. This approach also provides a means to qualify the importance of the elements which make up the landscape, thus defining the matrix of the landscape. A case study of the San Pedro National Conservation Ar

Abstract:

The purpose of this study is to examine the effects of land use and hydrology on surface water quality in a semi-arid watershed. Six synoptic sampling events were performed along the upper San Pedro River, AZ, USA before, during, and after the 2002 monsoon season. Water samples were analyzed for conservative solutes, nutrients, and organic matter. During non-monsoon baseflow periods, conservative solutes indicated limited hydrologic connection between regions. Protected reaches had significantly higher DOC concentrations and agricultural reaches had significantly higher DON and NO₃-N levels. I

Abstract:

The architectural intentions may best be described in the phrases: "symbolic meaning of the environment" - "the spirit of place" - and the need to assure the "historical continuity". The main points of the program are the following: 1.- to create a service unit corresponding to the needs of the overall development of the micro-region as regards to tourism, 2.- to favor contact between the tourists and the local population, 3.- to express this aim by means of an open type of structure, 4.- to offer a wide range of activities corresponding to the needs and desires of the occupants, 5.- no
