Changing Water Resources in the Indus Basin: A Multi‐Model Budyko‐Based Analysis

International Journal of Climatology, EarlyView.
Budyko‐based analysis evaluates historical (1962–2005) and future hydroclimatic change across the Indus River Basin. Budyko shifts indicate rising atmospheric evaporative demand and increasing energy limitation under future scenarios. ABSTRACT Assessing hydroclimatic variability and future water availability is crucial for sustainable water‐resource ...

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.

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.

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

Journal 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.

Spatial and Temporal Patterns of Extreme Hourly Rainfall in the Hawaiian Islands

International Journal of Climatology, EarlyView.
The extreme rainfall trends in Hawaiʻi were revealed by hourly rainfall data: Across islands, Kauaʻi and Hawaiʻi Island had larger events at a return period. Annual maximum series of 15 gauges showed significant positive trends. While extreme rainfall trends show increases or decreases regionally, the trends varied with rainfall duration.

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.

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

Station‐Based Assessment of Sub‐Seasonal Climate Trends in the Tyrolean Alps (Austria)

International Journal of Climatology, EarlyView.
In this study, we quantify the magnitude and significance of sub‐seasonal trends in the Tyrolean Alps (Austria) by collecting, processing and analysing meteorological observations from a dense network of climate stations. Our analysis indicates a warming rate of 0.43°C/dec over 1964–2023, greater sub‐seasonal trend variability when the analysis window ...

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

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 ...
