Evapotranspiration Of Kentucky Bluegrass, Lynda L. Fenton May 2010

Evapotranspiration Of Kentucky Bluegrass, Lynda L. Fenton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rapid population growth in arid regions of the western US is placing increased demand on water resources. Variability in precipitation and common occurrence of drought have promoted scrutiny of water use in urban lawns and gardens. However, few reliable measurements of water use of these landscapes exist. Quantifying the amount of water used vs. required by landscapes such as turfgrass would allow significant water conservation. Evapotranspiration (ET) is affected by biophysical factors such as: available energy, turbulent mixing, saturation deficit, soil water, and stomatal conductance. In order to simulate the water use by turfgrass, the relative importance of these processes …


Sudden Surface Warming/Drying Events Caused By Typhoon Passages Across Taiwan, T. C. Chen, Shih-Yu (Simon) Wang, M. C. Yen, A. J. Clark, J. D. Tsay Feb 2010

Sudden Surface Warming/Drying Events Caused By Typhoon Passages Across Taiwan, T. C. Chen, Shih-Yu (Simon) Wang, M. C. Yen, A. J. Clark, J. D. Tsay

Plants, Soils, and Climate Faculty Publications

Typhoon passages across Taiwan can generate sudden surface warming in downslope regions. Special characteristics and mechanisms for 54 such warming events that were identified during the 1961–2007 period are examined. Preferred warming regions were identified in northwest Taiwan, where warming is generated by downslope flow from east or northeast winds in westward-moving typhoons, and in southeast Taiwan, where it is generated by downslope flow from west or northwest winds in northwestward-moving typhoons. In addition to the orographic effect, warmings occurred exclusively within nonprecipitation zones of typhoons. Most northwest (southeast) warmings occur during the day (night) with an average lifetime of …
