Drivers of spatial and temporal variability of streamflow in the Incomati River basin [PDF]

Hydrology and Earth System Sciences, 2014
Abstract. The Incomati is a semi-arid trans-boundary river basin in southern Africa, with a high variability of streamflow and competing water demands from irrigated agriculture, energy, forestry and industries. These sectors compete with environmental flows and basic human water needs, resulting in a "stressed" water resource system.

Streamflow variability and the role of snowmelt in a marginal snow environment [PDF]

Arctic, Antarctic, and Alpine Research, 2020
Snowmelt in alpine regions supports hydroelectric power generation, water supply, and agricultural production. These regions are warming, and the impact on streamflow of changes in precipitation and the proportion falling as snow is of interest. We investigate the seasonality and interannual variability of streamflow in the Australian Alps, a key ...

Streamflow variability and optimal capacity of run‐of‐river hydropower plants [PDF]

Water Resources Research, 2012
The identification of the capacity of a run‐of‐river plant which allows for the optimal utilization of the available water resources is a challenging task, mainly because of the inherent temporal variability of river flows. This paper proposes an analytical framework to describe the energy production and the economic profitability of small run‐of‐river

Influence of Climate Variability and Reservoir Operation on Streamflow in the Yangtze River [PDF]

Scientific Reports, 2019
AbstractUnderstanding the effects of climate variability and reservoir operation on runoff is important for shipping, irrigation and water supply services, especially during extreme drought years. After the operation of the Three Gorges Dam (TGD) began, the discharge processes in the mid-lower reaches of the Yangtze River were completely different from

Hydrological response to twenty-first century climate change in the Amu Darya Basin, Central Asia

Journal of Hydrology: Regional Studies
Study regions: Amu Darya River, a transboundary river originated in the high mountains of Central Asia, provides water resources for 43 million people. The river is a hot spot for research and of high tension and conflicts among nearby countries.

Spatiotemporal differences in dominant drivers of streamflow evolution on the Loess Plateau

Frontiers in Earth Science, 2023
Previous studies have found that climate change and underlying surface change are the most direct and important drivers of the streamflow change in the Yellow River Basin.

Controls on spatial and temporal variability in streamflow and hydrochemistry in a glacierized catchment [PDF]

Hydrology and Earth System Sciences, 2018
Abstract. Understanding the hydrological and hydrochemical functioning of glacierized catchments requires the knowledge of the different controlling factors and their mutual interplay. For this purpose, the present study was carried out in two sub-catchments of the glacierized Sulden River catchment (130 km2; eastern Italian Alps) in 2014 and 2015 ...

Hydrologic similarity among catchments under variable flow conditions [PDF]

Hydrology and Earth System Sciences, 2011
An assessment of regional similarity in catchment stream response is often needed for accurate predictions in ungauged catchments. However, it is not clear whether similarity among catchments is preserved at all flow conditions.

Exacerbated Variability and Extremes in Streamflow Across Half of China From 1961 to 2018

Water Resources Research
Global warming has significantly altered the hydrological cycle and increased the frequency and intensity of extreme hydrological events. Therefore, quantifying trends in the variability and extremes of streamflow is crucial for deepening our ...

Coupled oceanic‐atmospheric variability and U.S. streamflow

Water Resources Research, 2005
A study of the influence of interdecadal, decadal, and interannual oceanic‐atmospheric influences on streamflow in the United States is presented. Unimpaired streamflow was identified for 639 stations in the United States for the period 1951–2002. The phases (cold/negative or warm/positive) of Pacific Ocean (El Niño–Southern Oscillation (ENSO) and ...
