DescriptionHell Canyon and Sycamore Canyon are major ungaged tributaries in the upper Verde River basin of central Arizona. Gage data imply that the record discharge of 1507 ems on February 20, 1993 at the Verde River gage near Clarkdale, Arizona was derived primarily from these tributaries. Reconstructions of 1993 flows measure 800-900 ems in Sycamore Canyon and 600-700 ems in Hell Canyon. Historic and pre-historic flood sequences were examined in various stratigraphic exposures in these canyons; as many as 11 floods are recorded at any one site. The 1993 floodwaters typically over top all prior flood stratigraphy; however, dendrochronology suggests that similar floods occurred prior to the gage record. These results confirm that Hell Canyon and Sycamore Canyon are major contributors to floods on the Verde River in both the historical and paleoflood record.

Determining Areal Precipitation in the Basin and Range Province of Southern Arizona - Sonoita Creek BasinBen-Asher, J.; Randall, J.; Resnick, S.; Water Resources Research Center, University of Arizona, Tucson, Arizona 85721 (Arizona-Nevada Academy of Science, 1976-05-01)A linear relationship between point precipitation and elevation in conjunction with a computer four-point interpolation technique was used to simulate areal rainfall over Sonoita Creek Basin, Arizona. The simulation's sensitivity and accuracy were checked against the official isohyetal map of Arizona (Univ. of Arizona, 1965) by changing the density of the interpolation nodes. The simulation was found to be in good agreement with the official map. The average areal-rainfall was calculated by integration. Cumulative rainfall amounts were assumed to be stochastically independent from one season to another. The seasonal precipitations of forty years (1932-1972) were subdivided into five groups. to check for binomial distribution. The binomial model fits the historical data adequately. The binomial model for cumulative seasonal areal-precipitation provides one way to compute the return period. This information will be necessary for decision-makers and hydrologists to predict the area's future water balance.
Incorporating social-ecological considerations into basin-wide responses to climate change in the Colorado River BasinBair, Lucas S; Yackulic, Charles B; Schmidt, John C; Perry, Denielle M; Kirchhoff, Christine J; Chief, Karletta; Colombi, Benedict J; Univ Arizona, Sch Anthropol; Univ Arizona, Dept Soil Water & Environm Sci (ELSEVIER SCI LTD, 2019-05-06)During the last 50 years, construction of dams in the western United States declined. This is partly because of increasing recognition of diverse and unintended social-ecological consequences of dams. Today, resource managers are recognizing the wide array of tradeoffs and are including a more diverse group of stakeholders in decision making for individual dams. Yet decisions at the regional scale maintain a focus on a limited number of resources and objectives, leading to inefficient and inequitable outcomes. Social-ecological changes compounded by climate change challenge this management paradigm. Increasing water demands for humans and the environment and renewed interest in hydropower present opportunities for operations that include climate change mitigation and adaptation strategies while considering tradeoffs and equitable responses at the regional scale.
