- Physics-Informed Neural Networks-Based Salinity Modeling in the . . . - MDPI
Salinity in estuarine environments has been traditionally simulated using process-based models More recently, data-driven models including artificial neural networks (ANNs) have been developed for simulating salinity Compared to process-based models, ANNs yield faster salinity simulations with comparable accuracy However, ANNs are often purely data-driven and not constrained by physical
- Characterizing Changes in Streamflow and Sediment Supply in the . . . - MDPI
A daily watershed model of the Sacramento River Basin of northern California was developed to simulate streamflow and suspended sediment transport to the San Francisco Bay-Delta To compensate for sparse data, a unique combination of model inputs was developed, including meteorological variables, potential evapotranspiration, and parameters defining hydraulic geometry A slight decreasing
- Climate Change Impacts and Water Management Adaptation in Two . . .
Climate change is bringing more risk and uncertainty to water management in the world’s Mediterranean-climate regions In this paper, we compare two Mediterranean-climate watersheds: the Durance basin in southern France, and the Sacramento River in northern California, USA For the Durance basin, we present new research on climate change impacts on water management, and discuss their
- Novel Salinity Modeling Using Deep Learning for the Sacramento–San . . .
Water resources management in estuarine environments for water supply and environmental protection typically requires estimates of salinity for various flow and operational conditions This study develops and applies two novel deep learning (DL) models, a residual long short-term memory (Res-LSTM) network, and a residual gated recurrent unit (Res-GRU) model, in estimating the spatial and
- Quantifying Apparent Groundwater Ages near Managed Aquifer Recharge . . .
The application of the cosmogenic radioisotope sulfur-35 (35S) as a chronometer near spreading basins is evaluated at two well-established Managed Aquifer Recharge (MAR) sites: the Atlantis facility (South Africa) and Orange County Water District’s (OCWD’s) Kraemer Basin (Northern Orange County, CA, USA) Source water for both of these sites includes recycled wastewater Despite lying
- Health Risk Assessment for Inhalation Exposure to Methyl . . . - MDPI
Methyl tertiary butyl ether (MTBE), a well known gasoline additive, is used in China nationwide to enhance the octane number of gasoline and reduce harmful exhaust emissions, yet little is known regarding the potential health risk associated with occupational exposure to MTBE in petrol stations In this study, 97 petrol station attendants (PSAs) in southern China were recruited for an
- Resilient Governance of Water Regimes in Variable Climates . . . - MDPI
Highly variable water regimes, such as California’s, contain distinctive problems in the pursuit of secure timing, quantities and distributions of highly variable flows Their formal and informal systems of water control must adapt rapidly to forceful and unpredictable swings on which the survival of diversified ecosystems, expansive settlement patterns and market-driven economies depends
- Water Security Under Climate Change: Challenges and Solutions . . . - MDPI
Different countries face significant challenges in managing water-related natural hazards, such as floods and shortages, while ensuring adequate water quality and quantity to satisfy human needs and preserve ecosystems Climate change projections exacerbate this situation by intensifying the hydrological cycle, resulting in substantial changes in precipitation patterns, evapotranspiration, and
