Introduction

The Delta Stewardship Council is leading an effort to create better practices for ecosystem modeling to inform Delta decision makers with the best available and useable information. As one of the key actions, the Delta Science Plan calls for the development of a collaborative community-modeling framework. The Council has formed an Integrated Modeling Steering Committee (IMSC) to bring together model developers, model users, managers, and executives from all different professional backgrounds working on complex Delta issues. The IMSC’s charge is to develop a strategic plan for building a sustainable modeling community and a governance framework that links the short (1-5 years), intermediate (5-10 years), and long-term (10-30 years) decision universe with key management questions. Toward this end, this model inventory includes models in current use in the Delta across a range of engineering, science, and social science disciplines. This inventory was developed through the combined expertise of individuals working in the different domains identified. Each model description contains a brief summary and features that are pertinent to future model integration. This model inventory is meant to be a living document and will be updated over time as models are updated, new studies are completed, and new models are developed.
