Winter streamflow variability, Yukon Territory, Canada

Hydrological Processes, 2002
AbstractKnowledge of winter streamflow regimes is required in northern catchments to evaluate water supply and to assess the vulnerability of aquatic habitat. The objective of this study was to explore the nature and causes of winter streamflow variability in northern rivers through examination of a limited number of case studies involving intensive ...

Wavelet analysis of variability in annual Canadian streamflows

Water Resources Research, 2004
Wavelet analysis is used to identify and describe variability in annual Canadian streamflows and to gain insights into the dynamical link between the streamflows and the dominant modes of climate variability in the Northern Hemisphere. Results from applying continuous wavelet transform to mean annual streamflows from 79 rivers selected from the ...

Model Flow Duration and Streamflow Variability

Water Resources Research, 1971
A simple flow duration model is postulated by using data from 120 gaging stations in Illinois. On the basis of model flow duration, a region can be divided into hydrologic divisions. For each division, the coefficient and exponent in the model have distributions with respect to percent time.

Implications of Streamflow Variability and Predictability for Lotic Community Structure: A Regional Analysis of Streamflow Patterns

Canadian Journal of Fisheries and Aquatic Sciences, 1989
Long-term discharge records (17–81 yr) of 78 streams from across the continental United States were analyzed to develop a general quantitative characterization of streamflow variability and predictability. Based on (1) overall flow variability, (2) flood regime patterns, and (3) extent of intermittency, 11 summary statistics were derived from the ...

Streamflow variability in the Southern Appalachians and atmospheric teleconnections

River Research and Applications, 2010
ABSTRACTWe have examined streamflow variability in the Southern Appalachian region of the United States for the period 1950–2009. In particular, we have analysed the monthly discharge time series at two stations along the following rivers in North Carolina: (1) Little Tennessee River (LTR) near Prentiss and (2) French Broad River in Asheville.

Streamflow Variability in the United States: 1931–78

Journal of Climate and Applied Meteorology, 1985
Abstract Systematic modes of spatial and temporal variation in a 48-year record of streamflow are defined using principal components. The components were calculated from a matrix of annual streamflow departures for 106 grid cells covering the United States in the years 1931–78.

Precipitation and Streamflow Variability in Northwestern Oklahoma, 1894-2003

Physical Geography, 2006
This paper utilizes time-series analysis to examine precipitation and streamflow variability in northwestern Oklahoma over the period 1894-2003. Trends and periodicities in the hydroclimatic variables were investigated using, respectively, Mann-Kendall test and continuous wavelet transform (CWT) methods.

Rating curve based assessment of seasonal variability of sulfate in streamflow

Environmental Monitoring and Assessment, 2018
Though constituent concentrations and loads in rivers exhibit apparent seasonal fluctuations, they are characterized by event-driven nature of the fluctuations in respond to natural processes and seasonal anthropogenic activities. This study aimed at establishing relationship between streamflow and sulfate load in Gin River, the major water source in ...

Streamflow Variability, Seasonal Forecasting and Water Resources Systems

2000
The interannual variability of streamflow in Australia is greater than elsewhere in the world. Reliable forecasts of streamflow would go a long way towards improving the management of water resources systems by enabling them to cope better with the high inter-annual variability. In the first part of this paper, a clear link between runoff in Australian

Trend detection of streamflow variables in Turkey

2019
This paper applies a procedure that identifies trends in streamflow variables in Turkey. The procedure utilizes the Mann-Kendall non-parametric test to detect trends. The research investigates three annual streamflow variables including annual minimum, mean and maximum streamflows and monthly mean streamflows for a network of 84 Turkish streamflow ...
