The upsurge of interest in watershed management and planning has increased the need for user friendly, interactive methods that decision makers can use to evaluate the economic and environmental consequences of alternative land use/management practices (LUMPs). Knowledge and information from several disciplines are integrated into a functional computer-based watershed management decision suppor...

INTRODUCTION: EDYS (Ecological DYnamics Simulation Model) is a general ecosystem simulation model that is mechanistically based and spatially explicit (Childress and McLendon 1999; Childress et al. 1999, 2002). The model simulates natural and anthropogenic-induced changes in plant, soil, animal, and watershed components across landscapes, at spatial scales ranging from 1 m or less to landscape ...

Availability of the mouse genome sequence will have a major impact on the study of vertebrate evolution, mammalian biology, and animal models of human disease. Resources to explore genome biology in mice will maximize the effect of this watershed event.

This paper addresses the problem of decomposing a polyhedral surface into “meaningful” patches. We describe two decomposition algorithms – flooding convex decomposition and watershed decomposition, and show experimental results. Moreover, we discuss three applications which can highly benefit from surface decomposition. These applications include content-based retrieval of threedimensional mode...

How can spatially explicit nonlinear regression modelling be used for obtaining nonpoint source loading estimates in watersheds with limited information? What is the value of additional monitoring and where should future data-collection efforts focus on? In this study, we address two frequently asked questions in watershed modelling by implementing Bayesian inference techniques to parameterize ...

Many researchers have examined the impact of detailed soil spatial information on hydrological modelling due to the fact that such information serves as important input to hydrological modelling, yet is difficult and expensive to obtain. Most research has focused on the effects at single scales; however, the effects in the context of spatial aggregation across different scales are largely missi...
