Assessing Phosphorus Sources With A Gis-Based Phosphorus Risk Index In A Mixed-Use, Montane Watershed, Josiah A. Johns
Assessing Phosphorus Sources With A Gis-Based Phosphorus Risk Index In A Mixed-Use, Montane Watershed, Josiah A. Johns
Theses and Dissertations
Elevated phosphorus (P) loading of freshwater lakes and reservoirs often results in poor water quality and negative ecological effects. Critical source areas (CSA) of P in the watershed can be difficult to identify and control. A useful concept for identification of a CSA is the P risk index (P Index) that evaluates the P risk associated with distinct source and transport pathways. The objectives of this study were to create a GIS model that adapts the Minnesota (MN) P Index for use at the watershed scale in a mixed-use, mountain environment, and to evaluate its effectiveness relative to field-based assessment. …

This paper provides an overview of myObservatory (myO), a free (for non-profit use) web-based information management system that specializes in multi-stakeholder, geospatial projects. myO important features include rich graphic and interactive data display, multiple data entry modes, user-access control tools, project-management tools, built-in and user-defined quality assurance tools, thorough and comprehensive documentation, and flexibility in customizing the system (e.g., by embedding user-defined algorithms) to meet special project needs.
