Resolution matters when modeling climate change in headwaters of the Colorado River
The continued growth of Southwestern cities depends on reliable water export from Rocky Mountain headwaters, which provide ∼85% of Colorado River Basin (CRB) streamflow. Despite being more sensitive to warming temperatures, alpine systems are simplified in the regional-scale models currently in use to plan for future water supply. We used an integrated hydrologic model that couples groundwater and surface water with snow and vegetation processes …
Adaptive capacity in social–ecological systems
Contrasting warming and drought in snowmelt-dominated agricultural basins
For snow-dominated basins like the San Joaquin in California, warmer temperatures affect hydrologic processes and stress water resources that support valuable irrigated agriculture and urban populations. Large inter-annual swings in precipitation, seen recently in California, highlight the need to better understand the effects of potential future warming combined with such extreme multi-year precipitation variability. In this study we use an inte…
Energy budget increases reduce mean streamflow more than snow–rain transitions
In snow-dominated mountain regions, a warming climate is expected to alter two drivers of hydrology: (1) decrease the fraction of precipitation falling as snow; and (2) increase surface energy available to drive evapotranspiration. This study uses a novel integrated modeling approach to explicitly separate energy budget increases via warming from precipitation phase transitions from snow to rain in two mountain headwaters transects of the central…
Groundwater-fed irrigation impacts spatially distributed temporal scaling behavior of the natural system
Regional scale water management analysis increasingly relies on integrated modeling tools. Much recent work has focused on groundwater–surface water interactions and feedbacks. However, to our knowledge, no study has explicitly considered impacts of management operations on the temporal dynamics of the natural system. Here, we simulate twenty years of hourly moisture dependent, groundwater-fed irrigation using a three-dimensional, fully integrate…
Human impacts on terrestrial hydrology
Global climate change is altering terrestrial water and energy budgets, with subsequent impacts on surface and groundwater resources; recent studies have shown that local water management practices such as groundwater pumping and irrigation similarly alter terrestrial water and energy budgets over many agricultural regions, with potential feedbacks on weather and climate. Here we use a fully-integrated hydrologic model to directly compare effects…
Hydrologic and land–energy feedbacks of agricultural water management practices
Recent studies demonstrate strong interdependence between groundwater dynamics, land surface water and energy fluxes over some regions, including significant negative correlation between latent heat flux and groundwater depth. Other studies show that irrigation increases latent heat flux and decreases the Bowen ratio (ratio of sensible to latent heat flux), with subsequent feedbacks on local and regional climate. We use an integrated hydrologic m…

HIV infection in the Women's Jail, Orange County, California, 1985 through 1991
The incidence and prevalence of human immunodeficiency virus (HIV) infection among injection drug users, prostitutes, and other women seeking confidential testing in the Orange County Women's Jail were assessed from 1985 to 1991. A total of 4616 voluntary tests were completed on 3051 women, and 865 women were tested repeatedly. Eighty-two women tested positively, a ratio of 1.8 positives per 100 tests or 2.7% of all persons tested. Cumulative HIV…
