Long-term changes and variability in rainfall and streamflow in Luvuvhu River Catchment, South Africa

South African Journal of Science, 2015
We investigated long-term changes and variability in daily rainfall and streamflow in the Luvuvhu River Catchment, South Africa. Changes and variability in rainfall and streamflow impact on available water resources and the allocation of these resources.

Causes of interannual to decadal variability of Gila River streamflow over the past century

Journal of Hydrology: Regional Studies, 2015
Study region: The Gila River, New Mexico, is characterized by two peaks in streamflow: one in the winter–spring (December–May), and summer (August–September). The region is influenced both by Pacific SST variability as well as the North American Monsoon.

Streamflow Analysis in Data-Scarce Kabompo River Basin, Southern Africa, for the Potential of Small Hydropower Projects under Changing Climate

Hydrology, 2022
In developing countries with data scarcity challenges, an integrated approach is required to enhance the estimation of streamflow variability for the design of water supply systems, hydropower generation, environmental flows, water allocation and ...

Evaluating climate change impacts on streamflow variability based on a multisite multivariate GCM downscaling method in the Jing River of China [PDF]

Hydrology and Earth System Sciences, 2017
Projected hydrological variability is important for future resource and hazard management of water supplies because changes in hydrological variability can cause more disasters than changes in the mean state.

Automated Adaptive Baseflow Separation Across Australia's Catchments Using AutoVL

Water Resources Research
Baseflow represents streamflow sustained between rainfall events and is fundamental to water security, ecosystem resilience, and drought management. However, widely used digital filters such as the Lyne–Hollick (LH) algorithm, when applied with a fixed ...

Anthropocene and streamflow: Long-term perspective of streamflow variability and water rights

Elementa: Science of the Anthropocene, 2019
Since 1981, water allocation in Chile has been based on a water use rights (WURs) market, with limited regulatory and supervisory mechanisms. The volume to be granted as permanent and eventual WURs is calculated from streamflow records, if stream gauge data are available, or from hydrologic parameter transfer from gauged to ungauged catchments, usually

Hydrologic impacts of cascading reservoirs in the middle and lower Hanjiang River basin under climate variability and land use change

Journal of Hydrology: Regional Studies, 2022
Study region: Middle and lower Hanjiang River (MLHR) basin, China. Study focus: Changes in streamflow are often due to intertwined factors like climatic variability, land use change, and hydraulic constructions, whose relative impact is however poorly ...

Disentangling the hydrological and hydraulic controls on streamflow variability in Energy Exascale Earth System Model (E3SM) V2 – a case study in the Pantanal region [PDF]

Geoscientific Model Development
Streamflow variability plays a crucial role in shaping the dynamics and sustainability of Earth's ecosystems, which can be simulated and projected by a river routing model coupled with a land surface model.

Influence of Indian Ocean high pressure on streamflow variability over southwestern Australia

Annals of Geophysics, 2014
 The seasonal and interannual variability of the southwestern Australia streamflow was examined based on re-analysis dataset from the National Centers for Environmental Prediction / National Center for Atmospheric Research, plus monthly streamflow data ...
