A Conceptualized Groundwater Flow Model Development for Integration with Surface Hydrology Model

, 2017
A groundwater system model was developed and calibrated in the study area of Lehman Creek watershed, eastern Nevada. The model development aims for integrating the surface hydrologic model - precipitation runoff modeling system (PRMS) model - with the ...

Impacts of Climate Change and Climate Variability on Hydropower Potential in Data-Scarce Regions Subjected to Multi-decadal variability [PDF]

, 2019
To achieve sustainable development of hydroelectric resources, it is necessary to understand their availability, variability, and the expected impacts of climate change.

Streamflow Response to Glacier Mass Loss Varies With Basin Precipitation Across Alaska

Water Resources Research
Diminishing glaciers affect streamflow, and given the extent of glaciers in Alaska and adjacent Canada, continued glacier mass loss is likely to have profound effects on ecosystems sensitive to runoff.

Multi‐objective optimization of reservoir refill operate considering energy storage and hydrological conditions

River, EarlyView.
Abstract Optimizing reservoir refill operation rules is crucial for enhancing reservoir sustainability and resilience. This study proposes a refill operation model designed to derive optimal refill guide curves by considering flood risk prevention, maximum storage levels, and the combined benefits of hydropower generation and energy storage.

Multi-decadal trends in global terrestrial evapotranspiration and its components [PDF]

, 2016
Evapotranspiration (ET) is the process by which liquid water becomes water vapor and energetically this accounts for much of incoming solar radiation. If this ET did not occur temperatures would be higher, so understanding ET trends is crucial to predict

Temporal community change in stream ecosystems varies by assemblage across US climates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Higher-order internal modes of variability imprinted in year-to-year California streamflow changes

Communications Earth & Environment
Climate internal variability plays a crucial role in the hydroclimate system, and this study quantifies its predictability on streamflow in California using historical observations, climate simulations, and various machine learning (ML) models.

GOVERNING THE CLOUD: Infrastructural Statecraft and the Political Ecology of Digital Expansion in Oregon

International Journal of Urban and Regional Research, EarlyView.
Abstract Oregon's wave of data center and semiconductor projects shows how cloud capitalism reorganizes resource systems and territorial governance. Examining Amazon, Google, and Intel, the article traces how fiscal incentives, utility programs, and land‐use instruments are recalibrated to secure hyperscale loads.
