Detection, attribution, and sensitivity of trends toward earlier streamflow in the Sierra Nevada [PDF]

open access: yes, 2007
Observed changes in the timing of snowmelt dominated streamflow in the western United States are often linked to anthropogenic or other external causes.

Using a Gridded Global Dataset to Characterize Regional Hydroclimate in Central Chile [PDF]

open access: yes, 2013
Central Chile is facing dramatic projections of climate change, with a consensus for declining precipitation, negatively affecting hydropower generation and irrigated agriculture. Rising from sea level to 6000 m within a distance of 200 km, precipitation

Assessment of alterations of river flow regimes using hydro-geomorphological parameters [PDF]

open access: yesPresent Environment and Sustainable Development
Climate change and anthropogenic activities can alter the streamflow regime by modifying critical elements of the flow regime. The aim of this work is to determine, by means of characteristic indices of rates of change and variability, the stage of ...

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

open access: yesJournal 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.

Hydrological Alteration Index as an Indicator of the Calibration Complexity of Water Quantity and Quality Modeling in the Context of Global Change [PDF]

open access: yes, 2019
Modeling is a useful way to understand human and climate change impacts on the water resources of agricultural watersheds. Calibration and validation methodologies are crucial in forecasting assessments.

Spatial and Temporal Variability of Canadian Seasonal Streamflows

open access: yesJournal of Climate, 2005
Abstract Wavelet and cross-wavelet analysis are used to identify and describe spatial and temporal variability in Canadian seasonal streamflows, and to gain insights into the dynamical relationship between the seasonal streamflows and the dominant modes of climate variability in the Northern Hemisphere.
