Whole effluent toxicity testing ensures wastewater does not harm aquatic life.
tTools for ArcGIS
An ArcMap Python add-in with tools that analyze stream-channel attributes and near-stream topography and vegetation to estimate effective shade inputs for use in temperature modeling programs.
We collect data on the health of environmental systems that support plant and animal life.
tTools for ArcGIS 9.x (Build 7.5.3)
An older version (for 9.x) of an ArcMap Python add-in with tools that analyze stream-channel attributes and near-stream topography and vegetation to estimate effective shade inputs for use in temperature modeling programs.
Puget Sound Tide Model
A research tool programmed in Python by David Finlayson for predicting the tides of the Sound. The model was originally developed by Lavelle et al. (1988) at NOAA PMEL and subsequently updated by H. Mofjeld to include the full suite of standard tidal constituents.
Models & spreadsheets
Computer models predict changes and spreadsheets calculate. We offer these tools to the public.
Eyes over Puget Sound
We use aerial photos and data from our monitoring stations and ferries to report on Puget Sound.
A solar position and solar radiation calculator for Excel/VBA.
Manning's n calculator
An Excel/VBA program to calculate Manning's n (or depth) from cross-section data for trapezoidal or rectangular channels based on equation 14.32 in Chapra's Surface water quality modeling textbook.
