Assessment of streamflow variability modes in Turkey: 1964–1994

open access: yesJournal of Hydrology, 2006
The systematic modes of spatial and temporal variation in 372-month records of streamflow in Turkey are defined using the principal components (PCs) analysis. The PCs were computed from a matrix of monthly records of 78 stations during the period 1964-1994.

Sensitivity of Regulated Streamflow Regimes to Interannual Climate Variability [PDF]

open access: yesEarth's Future, 2019
The simultaneous growth in climate‐driven alterations of the hydrologic cycle and global freshwater demand threatens the security of anthropogenic and ecologic uses of streamflows. However, the impact of damming on the response of river regimes to long‐term climate variability has not been fully disclosed yet.

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

open access: yesFrontiers 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.

Development of Threshold Levels and a Climate-Sensitivity Model of the Hydrological Regime of the High-Altitude Catchment of the Western Himalayas, Pakistan [PDF]

open access: yes, 2019
Water shortages in Pakistan are among the most severe in the world, and its water resources are decreasing significantly due to the prevailing hydro-meteorological conditions.

Space‐time variability of low streamflows in river networks [PDF]

open access: yesWater Resources Research, 2000
A low‐flow equation is derived from Darcy's law and a mass balance equation for base flow from a hillside by assuming that groundwater recharge is constant over short time periods. This low‐flow equation reduces to many of the existing mechanistic low‐flow equations, but in its general form looks like a linear regression model and captures spatial ...

Effects of climate on temporal variability in streamflow and salinity in the Upper Colorado River Basin

open access: yesJournal of Hydrology: Regional Studies
Study Region: The Upper Colorado River Basin, a critical water source for more than 40 million people in the western United States. Study Focus: Potential decreasing streamflow and elevated salinity concentrations threaten this resource.

Hydrologic similarity among catchments under variable flow conditions [PDF]

open access: yesHydrology 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.

Future shift in winter streamflow modulated by the internal variability of climate in southern Ontario [PDF]

open access: yesHydrology and Earth System Sciences, 2020
Fluvial systems in southern Ontario are regularly affected by widespread early-spring flood events primarily caused by rain-on-snow events. Recent studies have shown an increase in winter floods in this region due to increasing winter temperature and ...

Effects of seasonability and variability of streamflow on nearshore coastal areas: final report [PDF]

open access: yes, 1977
General nature and scope of the study: This study examines the variability of streamflow in all gaged Alaskan rivers and streams which terminate in the ocean. Forty-one such streams have been gaged for varying periods of time by the U. S.

Revisiting hysteresis of flow variables in monitoring unsteady streamflows [PDF]

open access: yesJournal of Hydraulic Research, 2020
Conventional streamflow monitoring methods entail one-to-one relationships between two flow variables obtained by combining direct flow measurements with statistical analyses.
