Summary Regionalization procedures are an important tool for estimating streamflow hydrography; however, there are difficulties associated with properly evaluating hydrological processes. This study aimed to propose a new explanatory variable for regionalization of the long-term average streamflow (Qlt) and permanent streamflow (present 95% of the ...

A metric for attributing variability in modelled streamflows
Journal of Hydrology, 2016Abstract 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.

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)

Intra‐annual variability of urban effects on streamflow
Hydrological Processes, 2021AbstractWhile considerable research has established the impacts of urbanization on streamflow, there has been little emphasis on how intra‐annual variations in streamflow can deepen the understanding of hydrological processes in urban watersheds. This study fills this critical research gap by examining, at the monthly scale, correlations between land ...

Rainfall and streamflow variability in Ghana
, 2012 The objective of this research is to investigate the variability of rainfall and streamflow over Ghana. Analyses of rainfall shows larger daily variability and maxima amounts in the southern coastal belt than in either the middle or northern parts of the

Effect of rainfall variability on streamflow simulation
Water Resources Research, 1969Three recording rain gages in a 9.7‐square‐mile basin in southern California were used with a deterministic rainfall‐runoff model to simulate flood hydrographs and peaks and to assess the effects of data errors on simulation results. Bias in the estimation of effective basin rainfall seemed to result in curve fitting parameter adjustments which ...

Streamflow Generation by Variable Source Area
1988For many years, hydrologists and engineers alike have attempted to describe and model the processes that generate streamflow from rainfall. Modern understanding of runoff processes expanded rapidly in the twentieth century. Horton (1933) proposed that the soil surface partitions rainfall into overland flow and ground water. Simply stated, when rainfall

Wavelet analysis of variability in annual Canadian streamflows
Water Resources Research, 2004Wavelet 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, 1971A 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.

Winter streamflow variability, Yukon Territory, Canada
Hydrological Processes, 2002AbstractKnowledge 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 ...
