Water Resources Research

The Research Publications track research that is published across national and international peer-reviewed journals. The most recent articles are available ahead of print and searchable by Journal Title, Subject, USDA Grant Funding Agencies or FDA Grant Funding Agencies. The research publications are tracked across five subject areas: Bacterial Pathogens, Chemical Contaminants, Natural Toxins, Parasites, and Viruses.

Use of Real‐Time Control (RTC) technology in Rainwater Harvesting Systems (RWH) can improve performance across water supply, flood protection, and environmental flow provision. Such systems make the most of rainfall forecast information, to release water prior to storm events and thus minimise uncontrolled overflows. To date, most advanced applications have adopted 24‐hr forecast information,...

Radar rainfall nowcasting, the process of statistically extrapolating the most recent rainfall observation, is increasingly used for very‐short‐range rainfall forecasting (less than six hours ahead). We performed a large‐sample analysis of 1533 events, systematically selected for four event durations and twelve lowland catchments (6.5—957 km2), to determine the predictive skill of nowcasting....

A flood forecasting system commonly consists of at least two essential components, i.e., a numerical weather prediction (NWP) model to provide rainfall forecasts and a hydrological/hydraulic model to predict the hydrological response. Whilst being widely used for flood forecasting, hydrological models only provide a simplified representation of the physical processes of flooding due to negligence...

Sedimentation and turbidity have effects on habitat suitability in the San Francisco Bay‐Delta (Bay‐Delta), concerning key species in the bay as well as the ability of the delta marshes to keep pace with sea level rise. A daily rainfall runoff and transport model of the Sacramento River Basin of northern California was developed to simulate streamflow and suspended sediment transport to the Bay‐...

Recent technological advances in representation of processes in numerical climate models have led to skilful predictions, which can consequently increase the confidence of hydrological predictions and usability of hydro‐climatic services. Given that many water‐related stakeholders are affected by seasonal hydrological variations, there is a need to manage such variations to their advantage...

We propose a set of new indices to assist global sensitivity analysis (GSA) in the presence of data allowing for interpretations based on a collection of diverse models whose parameters could be affected by uncertainty. Our GSA metrics enable us to assess the sensitivity of various features (as rendered through statistical moments) of the probability density function of a quantity of interest...

The quality of the forecasts, i.e., the accuracy in predicting the observed streamflow, affects the decisions that can be taken thus determining the success or failure of hydropower operations, i.e., the so‐called forecast value. Although pre‐processing techniques can be employed to improve forecast quality, the corresponding improvement in forecast value to hydropower is not straightforward to...

The one‐dimensional advection‐dispersion equation with streamwise boundaries has been used to model a wide range of real‐world processes including groundwater contaminant transport, atmospheric plume deposition, and the movement of planktonic organisms and migratory animals through riverine systems. Imposing boundary conditions at upstream and downstream locations complicates the analysis of this...

The identification of natural fractures and the wells they connect is crucial for the development of geological reservoirs because it may have an important impact on reservoir model construction and hydraulic fracture propagation. In this study we investigated the use of a novel data source, the microbial community composition in the reservoir formation fluids, for identification of interwell...

Cooperation in transboundary river basins can make water resources systems more efficient and benefit riparian stakeholders. However, in a basin with upstream and downstream stakeholders that have different interests, non‐cooperative outcomes have often been observed. These can be described by a one‐shot prisoners’ dilemma game where non‐cooperation (defection) is a dominant equilibrium strategy...

Increasingly variable hydrologic regimes combined with more frequent and intense extreme events are challenging water systems management worldwide. These trends emphasize the need of accurate medium‐ to long‐term predictions to timely prompt anticipatory operations. Despite in some locations global climate oscillations and particularly the El Niño Southern Oscillation (ENSO) may contribute to...

In a recent article in this journal, Luby, Polasky, and Swackhamer come to the provocative conclusion that urban water prices in the United States are “cheaper when drier.” They also argue that utilities fail to provide affordable water and that they charge less for “additional” use compared to “essential” use. We challenge these claims. While the authors correctly point out the many challenges...

We propose a time series modeling approach based on nonlinear dynamical systems to recover the underlying dynamics and predictability of streamflow and to produce projections with identifiable skill. First, a wavelet spectral analysis is performed on the time series to identify the dominant quasiperiodic bands. The time series is then reconstructed across these bands and summed to obtain a signal...

Phase five of the Coupled Model Intercomparison Project enabled a range of decadal modeling experiments where climate models were initialized with observations and allowed to evolve freely for 10–30 years. However, climate models struggle to realistically simulate rainfall and the skill of rainfall prediction in decadal experiments is poor. Here, we examine how predictions of sea surface...

ABSTRACT Food contamination is responsible for thousands of deaths worldwide every year. Plants represent the most common pathway for chemicals into the human and animal food chain. Although existing dynamic plant uptake models for chemicals are crucial for the development of reliable mitigation strategies for food pollution, they nevertheless simplify the description of physicochemical processes...
