Fluvial sediment transport studies have long underscored the difficulty in reliablyestimating transport model parameters, collecting accurate observations, and makingpredictions because of measurement error, natural variability, and conceptual modeluncertainty. Thus, there is a need to identify modeling frameworks that accommodate theserealities while incorporating functional relationships, providing probability-basedpredictions, and accommodating for conceptual model discrimination. Bayesian statisticalapproaches have been widely used in a number of disciplines to accomplish just this, yetapplications in sediment transport are few. In this paper we propose and demonstrate aBayesian statistical approach to a simple sediment transport problem as a means toovercome some of these challenges. This approach provides …

Particulate matter (PM) emissions from agricultural operations are an important issue for air quality and human health and a topic of interest to government regulators. PM emission rates from a dairy in the San Joaquin Valley of California were investigated during June 2008. The facility had 1,885 total animals, including 950 milking cows housed in free-stall pens with an open-lot exercise area, and 935 dry cows, steers, bulls, and heifers housed in open lots. Point sensors, including filter-based aerodynamic mass samplers and optical particle counters (OPC), were deployed at select points around the facility to measure optical and aerodynamic particulate …
