Ecohydrological Implications of Woody Plant Encroachment

Increases in the abundance or density of woody plants in historically semiarid and arid grassland ecosystems have important ecological, hydrological, and socioeconomic implications. Using a simplified water-balance model, we propose a framework for conceptualizing how woody plant encroachment is likely to affect components of the water cycle within these ecosystems. We focus in particular on streamflow and the partitioning of evapotranspiration into evaporation and transpiration. On the basis of this framework, we suggest that streamflow and evaporation processes are affected by woody plant encroachment in different ways, depending on the degree and seasonality of aridity and the availability of subsurface water. Differences in landscape physiography, climate, and runoff mechanisms mediate the influence of woody plants on hydrological processes. View Document.

Emerging Chemical Contaminants

There is growing concern worldwide about aquifer pollution by large numbers of emerging, anthropogenic chemicals (ECs) that escape standard wastewater treatment. Inasmuch as the rapidly-growing, arid Southwest uses such effluent to recharge depleting aquifers, there is an acute need for a better understanding of and a more complete treatment process to protect human and environmental health. Important among these contaminants is a broad suite of endocrine-disrupting chemicals (EDCs) that include natural or synthetic hormones as well as compounds that mimic hormones and may interfere with the operation of endocrine systems even at concentrations of parts per trillion. Indeed, evidence now indicates that some aquatic organisms are adversely affected at these levels where treated wastewater is discharged into streams. The paper will elaborate on these points building a case that this issue deserves attention. By Frank Butterworth, Ken Janecek, and Ed Wolfe. View Document.

Reconnaissance Watershed Analysis on the Upper and Middle Verde Watershed

The quantity, quality, and timing of water generated in the watershed is the result of land uses and condition at smaller scales. Grazing, fire suppression, timber harvesting, roads, mining, urbanization, and other human uses have resulted in significantly changed hydrologic condition. Prepared by Lloyd Barnett and Richard Hawkins, U of A. View Document.
