Spatial and temporal variability of wet spells and their role in wet and dry summers and winters in Australia

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The change in the frequency of wet spells in tropical Australia in summer primarily contributes to the change in precipitation between wet and dry years. In the extratropics, both the frequency and intensity of wet spells are important, especially in winter.

Water footprint of bio-energy and other primary energy carriers [PDF]

open access: yes, 2008
Freshwater is essential for life on earth, not only for basic human needs such as food, fibre and drinking water, but also for a healthy environment. In the near future, important challenges are to meet basic needs and to ensure that the extraction of ...

Software to Support Remote Sensing of River Discharge Based on Critical Flow Theory

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Water resource management requires accurate observations of streamflow but standard field methods for measuring river discharge (Q$$ Q $$) can be costly and hazardous for equipment and personnel. Remote sensing has become a viable alternative, but many image‐based techniques require field data for calibration, and depth and velocity can seldom

Dam It, I’m Stranded: Evaluating Fish Stranding Downstream of Two Hydropeaking Dams in Northern Ontario

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Globally, there has been an increase in the development and use of hydropower to produce energy. Hydropeaking is an operating regime that is used to meet real‐time energy demands; however, daily fluctuations in flows may result in fish becoming stranded.

Resilient Flow Regimes in the Rio Grande—Río Bravo Basin

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Water is essential for human development and is an indispensable resource for economic activity and a country's growth. However, current water practices, along with increasing land‐use change, climate change, and agricultural practices, have significantly altered the hydrological cycle and water availability.

The Transboundary Reach of the Columbia River: Cottonwood Colonization Followed Flow Moderation From the Columbia River Treaty Dams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The Columbia river provides the largest Pacific outflow in the Western Hemisphere and the greatest hydropower production of any North American river system. For hydropower generation and flood risk management, four massive water storage reservoirs followed the Columbia River Treaty between Canada and the United States, with three Canadian dams,

Injury Risks to a Migratory Freshwater Fish During Downstream Passage Through a Regulated Floodplain Outlet: A Case Study on Golden Perch (Macquaria ambigua)

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT River infrastructures such as weirs, dams, inlet and outlet regulators often impair connectivity, leading to degradation and loss of key habitats for riverine fishes. This also holds true for golden perch (Macquaria ambigua Richardson), a migratory species in Australia's Murray–Darling Basin.
