Climate And Landscape Controls On Seasonal Water Balance At The Watershed Scale, Xi Chen Jan 2014

Climate And Landscape Controls On Seasonal Water Balance At The Watershed Scale, Xi Chen

Electronic Theses and Dissertations

The main goal of this dissertation is to develop a seasonal water balance model for evaporation, runoff and water storage change based on observations from a large number of watersheds, and further to obtain a comprehensive understanding on the dominant physical controls on intra-annual water balance. Meanwhile, the method for estimating evaporation and water storage based on recession analysis is improved by quantifying the seasonal pattern of the partial contributing area and contributing storage to base flow during low flow seasons. A new method for quantifying seasonality is developed in this research. The difference between precipitation and soil water storage …


Innovative Pollutant Load Monitoring, Eric Gurr Jan 2011

Innovative Pollutant Load Monitoring, Eric Gurr

Electronic Theses and Dissertations

Modern streamflow measuring equipment, water quality sampling techniques and a better understanding of pollutant washoff are continuously being developed as today's society is in critical need of improving water management, minimizing developmental impacts and preventing environmental hazards. In particular, the study of the spatial, temporal and volumetric characteristics of annual pollutant loading caused by variations in precipitation, land use and other anthropogenic factors is of great significance due to their relation to future global water demands. The research presented here falls in three parts. In the first part of the dissertation, an acoustical Doppler velocity profiler installed in a submerged …
