The Effects Of Climate Change And Urbanization On The Runoff Of The Rock Creek Basin, Jon J. Franczyk
The Effects Of Climate Change And Urbanization On The Runoff Of The Rock Creek Basin, Jon J. Franczyk
Dissertations and Theses
Climate changes brought on by global warming are expected to have a significant affect on the Pacific Northwest hydrology during the 21st Century. Current research anticipates higher mean annual temperatures and an intensification of the hydrological cycle. This is of particular concern for highly urbanized basins, which are considered more vulnerable to changes in climate. Because the majority of previous studies have addressed the influences of either climate or urban land cover changes on runoff, there is a lack of research investigating the combined effect of these factors. The Rock Creek basin (RCB), located in the Portland, OR, metropolitan …
Quantifying Twentieth Century Glacier Change In The Sierra Nevada, California, Hassan J. Basagic
Quantifying Twentieth Century Glacier Change In The Sierra Nevada, California, Hassan J. Basagic
Dissertations and Theses
Numerous small alpine glaciers occupy the high elevation regions of the central and southern Siena Nevada, California. These glaciers change size in response to variations in climate and are therefore important indicators of climate change. An inventory based on USGS topographic maps (l :24,000) revealed 1719 glaciers and perennial snow and ice features for a total area of 39.l5 ±7.52 km2. The number of 'true' glaciers, versus non-moving ice, is estimated to be 118, covering 15.87 ± 1.69 Km2. All glaciers were located on north to northeast aspects, at elevations >3000 m.
