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

Trends in Canadian streamflow [PDF]
Water Resources Research, 2001 This study presents trends computed for the past 30–50 years for 11 hydroclimatic variables obtained from the recently created Canadian Reference Hydrometrie Basin Network database. It was found that annual mean streamflow has generally decreased during the periods, with significant decreases detected in the southern part of the country.

Journal of Environmental Quality, EarlyView.Abstract Critical source areas (CSAs) are small areas of a field, farm, or catchment that account for most contaminant loss by having both a high contaminant availability and transport potential. Most work on CSAs has focused on phosphorus (P), largely through the work in the 1990s initiated by Dr.

Potential role of permafrost thaw on increasing Siberian river discharge
Environmental Research Letters, 2021 Despite the increasing Siberian river discharge, the sensitivity of streamflow to climate forcing/permafrost thawing is poorly quantified. Based on the Budyko framework and superposition principles, we detected and attributed the changes in streamflow ...

Using Wavelet to Analyze Periodicities in Hydrologic Variables
, 2017 The trend and shift in the seasonal temperature, precipitation and streamflow time series across the Midwest have been analyzed, for the period 1960-2013, using the statistical analyses (Mann- Kendall test with and without considering short term ...

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

Insights On Streamflow Predictability Across Scales Using Horizontal Visibility Graph Based Networks [PDF]
, 2019 Streamflow is a dynamical process that integrates water movement in space and time within basin boundaries. The authors characterize the dynamics associated with streamflow time series data from about seventy-one U.S. Geological Survey (USGS) stream-gauge stations in the state of Iowa. They employ a novel approach called visibility graph (VG).

Imputation of Missing Streamflow Data at Multiple Gauging Stations in Benin Republic [PDF]
arXiv, 2022 Streamflow observation data is vital for flood monitoring, agricultural, and settlement planning. However, such streamflow data are commonly plagued with missing observations due to various causes such as harsh environmental conditions and constrained operational resources.

Long-range properties and data validity for hydrogeological time series: the case of the Paglia river [PDF]
Physica A 470 (2017) 39-50, 2016 This paper explores a large collection of about 377,000 observations, spanning more than 20 years with a frequency of 30 minutes, of the streamflow of the Paglia river, in central Italy. We analyze the long-term persistence properties of the series by computing the Hurst exponent, not only in its original form but also under an evolutionary point of ...

Surface water irrigation reservoirs improve groundwater recovery in a heavily stressed aquifer
Journal of Environmental Quality, EarlyView.Abstract Expansion of irrigated cropland area in eastern Arkansas has led to the formation of regional cones of depression and creation of critical groundwater areas for the Mississippi River Valley alluvial aquifer (MRVA) in Arkansas. In response, use of surface water reservoirs for irrigation in the Grand Prairie critical groundwater area (GPCGA) has
