IWAC Irrigation Efficiency Webinars
The Idaho Washington Aquifer Collaborative has produced a series of on-demand webinars about landscape and Irrigation design strategies for improving water efficiency and why it is so important for protecting and conserving our sole source aquifer.
Mark Solomon, IWRRI, Idaho Water Demand
Mark Solomon, Ph.D., Water Research Scientist, Idaho Water Resources Research Institute (IWRRI), presented the Rathdrum Prairie Aquifer Water Demand study and detailed the process and methodology by which Idaho purveyors file water right applications based on Reasonably Anticipated Future Needs (RAFN).

The Spokane River: Modeling in a Changing Environment
WSU, CWU, Uof I and the University of Utah are collaborating on a NSF and USDA funded research grant named WISDM. Tung Nguyen and Heather Baxter explain the technical aspects to modeling the Spokane River ‘s low flow trends in a changing environment.
WISDM Presentation 4/8/14 – Melanie Thornton
The Watershed Integrated System Dynamics Modeling (WISDM) mission is to understand how climate and land use changes have affected water quantity and quality in recent decades, and how will climate variability and change impact water quantity and quality in the next few decades.

Spokane Valley Land & Water Company Canal 1907
A 1907 irrigation canal system from Post Falls Idaho to the Spokane Valley is recorded in the National Register of Historic Places and provides an example of bi-state collaboration.
County Water Demand Forecast Model Update
The updated Spokane County Water Demand Forecast Model presented by Mike Hermanson at the October 8, 2013 IWAC meeting.
Watershed Integrated System Dynamics Modeling
The WSU WISDM System Dynamics is an approach to studying and managing complex change over time for the SVRP Aquifer and Watersheds. It addresses internal feedback loops and time delays that affect the behavior of the entire system.
2012 SVRP Aquifer GSI Groundwater Flow Model
The 2012 SVRP Aquifer ground-water update and expanded model was commissioned by the City of Spokane, SAJB and the WA Department of Health Drinking Water. Based on the 2007 USGS modelling, it uses Microfem technology and a resolution that supports wellhead protection planning. John Porcello, Senior Groundwater Hydrologist at GSI Water Solutions, presented the model as a tool for wellfield-scale analysis as well as groundwater source management.
