Elevated phosphorus (P) loading from the watersheds draining into Lake Erie, particularly agricultural (53%) and urban (43%) sources, is identified as one of main drivers severe eutrophication. In this study, we present a comprehensive evaluation 11 process-based models to characterize water cycle well nutrient fate transport within watershed context, find robust replicable way optimize modelli...

Abstract Mike Lockwood and Mat Owens discuss how eclipse observations are aiding the development of a climatology near-Earth space

Hydrologic models are increasingly used as tools to predict stormwater quantity and quality from urban catchments. However, due to a range of practical issues, most models produce gross errors in simulating complex hydraulic and hydrologic systems. Difficulty in finding a robust approach for model calibration is one of the main issues. Though automatic calibration techniques are available, they...

Permeable pavements are a green infrastructure stormwater management practice that can serve as functional component of the site design. However, previous field studies suggest high uncertainty in parameters used for performing hydrologic calculations permeable pavements. The Environmental Protection Agency (EPA) Storm Water Management Model (SWMM) within PCSWMM software package was to simulate...

* I think David Lee for collaboration on related projects and Pat Kline and Demian Pouzo for unusually helpful comments. Mike Elsby provided a set of extremely detailed and insightful comments on an earlier draft. I am responsible for any errors.

The paper describes the MIKE (Model-based and Incremental Knowledge Engineering) approach for the development of knowledge-based systems (kbs). It integrates semiformal specification techniques, formal specification techniques, and prototyping into a coherent framework. This allows the domain and task model of a kbs to be described on different formalization levels. All activities in the buildi...

By the time of his death on 23 November 2012, Michael (Mike) E. Robbins had gained a national and, indeed, international , reputation as a leader in the fi eld of radiation-induced normal tissue eff ects. For the fi nal decade or so of his career, Mike had been based at Wake Forest Medical Center, an institution where he had developed a world-class research program looking at the prevention and...
