Environmental modeling frameworks support scientific model development by providing an Application Programming Interface (API) which model developers use to implement models. This paper presents results of an investigation on the framework invasiveness of environmental modeling frameworks. Invasiveness is defined as the quantity of dependencies between model code and the modeling framework. Thi...

The hazard from earthquake-generated tsunami waves is not only determined by the earthquake’s magnitude and mechanisms, distance to earthquake area, but also geomorphology of nearshore onshore areas, which can change over time. In coastal assessments, a changing environment commonly taken into account increasing sea-level projected values (static). However, changes other climate-change impacts ...

The environmental domain poses a number of important challenges for the modeling task. First, we have to deal with multiple dynamics that often involve spatial variations. The time-scales of the relevant phenomena range from long-term changes in climatic conditions to chemical reactions occurring within parts of a second. Second, we face largely incomplete knowledge in various respects. The obs...

Turbulent flow in complex geometries receives considerable attention due to its importance in many engineering applications. It has been the subject of interest for many researchers. Some of these interests include the design of storm water channels. The design of these channels requires testing through physical models. The main practical limitation of physical models is the so called “scale ef...

Prediction of the fate of pesticides in soil is of interest from an environmental (pollution) as well as an agricultural (efficacy, carryover) viewpoint. Two environmental parameters that control microbial degradation of pesticides in soil are moisture and temperature. This study was designed to quantify the impact of soil water content and temperature on microbial degradation rates of the inse...

For the support of analysis and decision making in the environmental domain, we propose a knowledge-based system with explicit representation of expertise in the domain and the specific ecosystem in the form of qualitative dynamic models. The choice of qualitative modeling techniques is motivated by the very nature of the processes examined, the available information and style of reasoning empl...

Influenza is an acute viral respiratory disease that has significant mortality, morbidity and economic burden worldwide. It infects approximately 5-15% of the world population, and causes 250,000 – 500,000 deaths each year. The role of environments on influenza is often drawn upon the latitude variability of influenza seasonality pattern. In regions with temperate climate, influenza epidemics e...

Environmental epidemiology requires effective models that take individual observations of environmental factors and connect them into meaningful patterns. Single-factor relationships have given way to multivariable analyses; simple additive models have been augmented by multiplicative (logistic) models. Each of these steps has produced greater enlightenment and understanding. Models that allow ...
