| Summary: | Comprehensive evaluation of changes in streamflow extremes and characteristics
due to climate change and variability is the main focus of this study. Available
streamflow data at several gaging stations in least anthropologically affected watersheds
of the Southeastern Gulf-Atlantic Region, were used for this analysis. To evaluate
influences due to climate change, nonparametric trend tests were applied to annual and
monthly extremes, while considering seasonality, along with changes in streamflow
characteristics. To understand climate variability influences, streamflow data is
partitioned in to cool and warm phases of four oceanic and atmospheric oscillations
known to have an effect on hydroloclimatology of the region: El Niño-Southern
Oscillation (ENSO), Pacific Decadal Oscillation (PDO); Atlantic Multi-decadal
Oscillation (AMO); and North Atlantic Oscillation (NAO). Generally, results showed
decreasing trends in overall streamflow extremes, as well as spatially varying, temporally non-uniform influences of climate variability on streamflow extremes and characteristics. === Includes bibliography. === Thesis (M.S.)--Florida Atlantic University, 2016. === FAU Electronic Theses and Dissertations Collection |
