Fire and Flood in a Canyon Woodland: The Effects of Floods and Debris Flows on the Past Fire Regime of Rhyolite Canyon, Chiricahua National Monument: Final ReportSwetnam, Thomas, Baisan, Christopher, Caprio, Tony, McCord, Alex, Brown, Peter January 1990 (has links)
Prior research in the Rhyolite Canyon area of Chiricahua National Monument (Swetnam et. al. 1989) revealed an anomalous 50 year fire-free interval between 1901 and 1851. Disruption of fire spread resulting from flooding and mass soil movement (debris flows) were postulated as potential causes of this long interval. The present study gathered additional evidence of fire and floods in the canyon system. Sampling of flood-scarred trees along stream channels successfully identified several flood events in Rhyolite canyon. Pulses of pine regeneration on debris flow deposits were associated with one of these events. However, no definitive linkage of flood events with changes in fire regime was established. Analysis of new fire scar samples combined with previous results indicated that the area affected by the change in fire regime includes the uplands between Jesse James Canyon and Rhyolite drainage. Source areas for fires prior to 1900 were not identified within the study area indicating that ignitions outside the present monument boundaries may have been important in the past. Evidence from the maximum ages of overstory conifers within Rhyolite Canyon suggests the occurrence of a major disturbance within this drainage prior to 1600.

Develop Water Management Methods for Watersheds Subject to Intensive Development: Partial Project Completion ReportDavis, D., Robotham, H. B. 09 1900 (has links)
OWRT Project No. A-069-ARIZ / Agreement No. 14-34-0001-6003 / Project dates: July 1975-September 1977 / Acknowledgement: The work upon which this report is based was supported by funds provided by the United States Department of the Interior, Office of Water Research and Technology, as authorized under the Water Resources Research Act of 1978. / A water resources management study for the Sonoita Creek watershed was conducted in order to develop a usable water resources management plan for the area and to resolve possible conflict among the different water demands in the basin. These water demands are classified as municipal and domestic, recreation and agriculture. Six potential water resources management alternatives are developed and compared using the standardized cost -effectiveness methodology. This approach enables thorough and efficient comparison of the alternatives with respect to both quantifiable and unquantifiable criteria. Each alternative considers developing either the ground water or the surface water resources of the watershed. Also, each alternative considers some method of treated
sewage effluent disposal. The algorithm ELECTRE I is used to select the most suitable plan for the
watershed. This procedure is used because of its simplicity and its proven usefulness in analyzing multiobjective decision problems. With the available information on the ground and surface water resources of the watershed, the choice of alternatives is reduced to one, namely, construction of a small reservoir at Redrock Canyon. Evaporation control measures are needed in order to reduce evaporation losses from the reservoir. The reservoir would serve as a supplemental source of water for the town of Patagonia and for the Sonoita Creek Sanctuary.
