A metric for attributing variability in modelled streamflows

Journal of Hydrology, 2016
Abstract Significant gaps in our present understanding of hydrological systems lead to enhanced uncertainty in key modelling decisions. This study proposes a method, namely “Quantile Flow Deviation (QFD)”, for the attribution of forecast variability to different sources across different streamflow regimes.

Identification of climate variables dominating streamflow generation and quantification of streamflow decline in the Loess Plateau, China

Science of The Total Environment, 2020
Precipitation-extremes-driven floods, which compose an important proportion of streamflow but cause severe adverse impacts in the Loess Plateau of China, urged the progressive implementation of ecological restoration (ER) strategies in the Loess Plateau (LP) of China. Knowledge of the linkage between climate variables (especially precipitation extremes)

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 ...

Improving Streamflow Reconstructions Using Oceanic-Atmospheric Climate Variability

World Environmental and Water Resources Congress 2014, 2014
Recurring hydrologic drought in Southwestern U.S. has raised questions about the reliability of future water supplies. Streamflow reconstruction using tree-ring chronologies (TRC) is used traditionally to expand the length of past streamflow records, which are helpful in long-term planning of water resource especially by giving information about ...

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

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.

Interannual variability and interdecadal trends in Hudson Bay streamflow

Journal of Marine Systems, 2011
Abstract This study investigates the interannual variability and interdecadal trends in streamflow input to Hudson Bay (including James Bay) over 1964–2008. The 23 rivers chosen for this study span a maximum gauged area of 2.54 × 106 km2 and collectively transport 522 km3 of freshwater to Hudson Bay each year.

Streamflow variability and classification using false nearest neighbor method

Journal of Hydrology, 2015
Summary Understanding regional streamflow dynamics and patterns continues to be a challenging problem. The present study introduces the false nearest neighbor (FNN) algorithm, a nonlinear dynamic-based method, to examine the spatial variability of streamflow over a region.

Analysis of streamflow droughts using fixed and variable thresholds

Hydrological Processes, 2018
AbstractHydrological drought analysis is very important in the design of hydrotechnical projects and water resources management and planning. In this study, a methodology is proposed for the analysis of streamflow droughts using the threshold level approach.

Large-scale climate teleconnections with South Korean streamflow variability

Hydrological Sciences Journal, 2019
Leading patterns of observed seasonal extreme and mean streamflow on the Korean peninsula were estimated using an empirical orthogonal teleconnection (EOT) technique.
