Freshwater Stream Monitoring Process Improvements for Fecal Indicator Impairment Designation
(2023-05)
Recreational water quality standards for freshwater streams and rivers are important to understand the potential human health risks associated with primary body contact recreation. Indicator bacteria, Enterococcus and ...
Quantifying the Impact of Experimental Factors on the Measurement of Dynamic Capillary Effects in Unsaturated Porous Media
(2014-12-12)
Multiphase flow is an important phenomenon in many natural and engineering systems; for example, oil recovery and water movement in the unsaturated zone are two common multiphase flow systems. The capillary pressure-saturation ...
Characterization and Prediction of Flash Flood Severity
(2017-05)
Flash floods, a subset of floods, are a particularly damaging natural hazard worldwide due to their multidisciplinary nature, difficulty in forecasting, and fast response that limits emergency responses. The purpose of ...
Determination of leakage from subsurface containment systems using informational entropy and hydraulic signature assessment methods.
(1998)
The use of physical and hydraulic containment systems for the isolation of contaminated ground water and aquifer materials associated with hazardous waste sites has increased during the last decade. The existing methodologies ...
Computer design of onsite residential lagoons from demographic, hydraulic and hydrologic variables /
(1985)
An investigative field study of onsite residential lagoon systems was conducted to identify important demographic, hydraulic and hydrologic variables affecting components of lagoon water balances. The goal was development ...
Impacts of heterogeneous sedimentary organic matter on phenanthrene sorption and fate processes.
(1999)
Natural attenuation is currently one of the most important topics in groundwater management. Sorption and biodegradation are key processes impacting the efficiency of natural attenuation. Although extensive literature has ...
Decadal development of CREST hydrological model family: review, improvements, applications, and outlook
(2022-08)
A hydrological model is an indispensable tool in Earth system science and engineering operations to understand, predict, and manage water resources on Earth. The Coupled Routing and Excess Storage (CREST) model, released ...
Characterizing components of uncertainty in hydrologic modeling using an ensemble approach.
(2003)
In hydrologic modeling, uncertainties are known to reside in model inputs, i.e., rainfall estimates, model parameters, observations of streamflow, and in some cases in the model structure itself. Estimation of the total ...
