The Object Modeling System (OMS) is a framework for environmental model development, data provisioning, testing, validation, and deployment. It provides a bridge for transferring technology from the research organization to the program delivery agency. The framework provides a consistent and efficient way to create science components, build, calibrate, and(More)
One of the most difficult tasks in the whole KDD process is to choose the right data mining technique, as the commercial software tools provide more and more possibilities together and the decision requires more and more expertise on the methodological point of view. Indeed, there are a lot of data mining techniques available for an environmental scientist(More)
The Soil and Water Assessment Tool (SWAT) has been used widely for large scale applications, reaching entire continents. Within the EU funded EnviroGrids project, a detailed application of SWAT on the Black Sea Basin is envisaged using high resolution data. In order to support the computation, the model is run on a computer grid. The use of the SWAT allowed(More)
Recent papers have called for the development of robust model diagnostics (in addition to traditional " measures of fit ") that provide insights on where model structural components and/or data may be insufficient. The potential of entropy measures to provide these in hydrology has not been adequately explored. Further, flow duration (FD) curves provide a(More)
Computer simulations using mathematical models provide useful tools to investigate different scenarios based on watershed management strategies and environmental conditions. To study the impact of these strategies and conditions, different models must be linked or coupled following hydrological pathways in air, soil and water. To connect one model to(More)
In this paper we describe our experience in the design and teaching of a new evolutionary introductory programming course in a new Distributed Computing and Communications Systems Technology program at the University of Guelph-Humber. This course is evolutionary and innovative because it integrates the use of HTML, JavaScript, and Java in a one-semester(More)
Calibration of hydrological models is an essential step for these models to simulate real world conditions as close as possible. Calibration is a tedious and timeconsuming process. An auto-calibration algorithm developed by Duan et al. [1] has been successfully used in hydrological modeling area. This algorithm suffers from high computational cost for(More)
