Streamflow response to forest management
Nature, 2020 Forests play a key part in the water cycle, so both planting and removing forests can affect streamflow. In a recent Article1, Evaristo and McDonnell used a gradient-boosted-tree model to conclude that streamflow response to forest removal is predominantly controlled by the potential water storage in the landscape, and that removing the world’s forests

Limnology and Oceanography, EarlyView.Abstract Stream water nutrient ratios are often influenced by flow variation and landscape characteristics. However, the influence of these drivers on total and dissolved nutrient ratios remains understudied, especially in prairie ecosystems where hydrologic connectivity between soils and streams exhibits substantial spatial and seasonal variability ...

Catchment-scale Richards equation-based modeling of evapotranspiration via boundary condition switching and root water uptake schemes [PDF]
, 2015 In arid and semiarid climate catchments, where annual evapotranspiration (ET) and rainfall are typically comparable, modeling ET is important for proper assessment of water availability and sustainable land use management. The aim of the present study is

Impacts of riverine heatwaves on rates of ecosystem metabolism in the United States
Limnology and Oceanography Letters, EarlyView.Abstract Rivers produce and decompose large amounts of carbon globally due, in part, to high rates of gross primary production (GPP) and ecosystem respiration (ER), collectively known as ecosystem metabolism. Water temperature is a major driver of ecosystem metabolism, and in‐stream temperatures are increasing globally, including extreme temperature ...

Human influences on streamflow drought characteristics in England and Wales [PDF]
Hydrology and Earth System Sciences, 2018 Human influences can affect streamflow drought characteristics and propagation. The question is where, when and why? To answer these questions, the impact of different human influences on streamflow droughts were assessed in England and Wales, across

STREAMFLOW FORECASTING IN SASKATCHEWAN [PDF]
Canadian Water Resources Journal, 1976 A streamflow forecasting program was instituted by Saskatchewan’s Hydrology Branch in the mid-1960’s to benefit water supply planning for the Squaw Rapids and South Saskatchewan River Projects. Since the spring of 1969, flood forecasting especially in the southeastern portion of the province has become the major component of forecasting activities ...
