 ERDC’s Coastal Hydraulics Laboratory (CHL) staff contributed a chapter to the English Geological Society, Special Publication 2012, v.362; Military Aspects of Hydrogeology published in January.

The chapter, "Opportunity-Driven Hydrological Model Development in U.S. Army Research and Development Programs," was co-authored by Drs. Chuck Downer, William D. Martin and Russ Harmon all with CHL and Dr. Fred Ogden of the University of Wyoming.

The chapter was produced at the invitation of the Geological Society. The chapter discusses the history of hydrological model development as influenced by changes in needs and technologies. It concludes with a description of the Gridded Surface/Subsurface Hydrologic Analysis (GSSHA) model and provides examples of its application in watersheds with varying hydrologic characteristics.
