Hydro-Climatic Variability: A Characterisation and Trend Study of the Awash River Basin, Ethiopia

open access: yesHydrology, 2019
The objective of this study was to characterize, quantify and validate the variability and trends of hydro-climatic variables in the Awash River Basin (ARB) in Ethiopia using graphical and statistical methods. The rainfall and streamflow trends and their

Annual stream flow variability over the western United States [abstract] [PDF]

open access: yes, 1988
EXTRACT (SEE PDF FOR FULL ABSTRACT): The variability of mean annual streamflow over the western United States is described and related to indices of large scale atmospheric circulation over the Pacific Ocean and western U.S.

Scenarios and strategies for future‐proofing ecosystem management under climatic novelty

open access: yesConservation Biology, EarlyView.
Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...

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.

The hole in the doughnut: Formalizing and testing a key model of degrowth

open access: yesContemporary Economic Policy, EarlyView.
Abstract Degrowth scholars often claim that capitalism generates social and ecological imbalances, as captured by Kate Raworth's leading doughnut model. We formalize this model using social and environmental indices and measure imbalances using their coefficient of variation.

Management strategy evaluation for salmon habitat restoration and hatchery supplementation

open access: yesConservation Science and Practice, EarlyView.
Building on three previously published studies, this paper applies population modeling work to evaluate the effects of different habitat and hatchery management strategies on achieving recovery goals for endangered Chinook salmon. We find that it would require a >150% improvement in juvenile survival to achieve recovery goals for population abundance ...

Hydrologic Trends in the Upper Nueces River Basin of Texas—Implications for Water Resource Management and Ecological Health

open access: yesHydrology, 2019
Reliable water sources are central to human and environmental health. In south Texas, USA, the Nueces River Basin (NRB) directly or indirectly plays that important role for many counties.

Long range experimental hydrologic forecasting for the eastern U.S. [PDF]

open access: yes, 2002
We explore a strategy for long-range hydrologic forecasting that uses ensemble climate model forecasts as input to a macroscale hydrologic model to produce runoff and streamflow forecasts at spatial and temporal scales appropriate for water management ...

Relationships Between Pacific and Atlantic Ocean Sea Surface Temperatures and U.S. Streamflow Variability

open access: yes, 2006
An evaluation of Pacific and Atlantic Ocean sea surface temperatures (SSTs) and continental U.S. streamflow was performed to identify coupled regions of SST and continental U.S. streamflow variability.

El Niño-Southern Oscillation (ENSO) controls on mean streamflow and streamflow variability in Central Chile

open access: yes, 2020
Understanding hydrological extremes is becoming increasingly important for future adaptation strategies to global warming. Hydrologic extremes affect food security, water resources, natural hazards, and play an important role in the context of erosional processes and landscape evolution.
