Ecology provides the high-quality science that is the foundation of Washington state environmental policy. Our monitoring, assessment, and modeling services provide a data-rich understanding of our state’s land, air, and water. We provide access to that data through reports, databases, maps and user-friendly online tools.

Data model: QUAL2KW - Version 6 (zip file)

A modeling framework for simulating river and stream water quality. Vversion 6 offers Non-steady, non-uniform flow using kinematic wave flow routing. Continuous simulation with time-varying boundary conditions for periods of up to one year. Also has the option to use repeating diel conditions similar to Version 5 but with either steady or non-steady flows.

River Metabolism Analyzer (RMA)

Excel workbook tool to apply four methods to analyze continuous monitoring data from a stream to analyze stream metabolism and reaeration. This tool can be used to solve for gross primary production, respiration, reaeration, and limitation due to light, temperature, nutrients, and predict response to parameter changes.
