Wildland Hydrology was established in 1985 by Dave Rosgen and specializes in training courses that focus on fluvial geomorphology, watershed assessment and management, river restoration, and monitoring. The training courses are designed to provide hands-on experience for professionals working with rivers and their watersheds. The course offerings allow individuals to progress through a range of interrelated courses beginning with the fundamentals in Basic Survey Skills and Applied River Morphology and continuing through the more complex River Restoration & Natural Channel Design.

Wildland Hydrology has also assessed, designed, implemented, and monitored over 70 large-scale river restoration projects throughout North America in addition to projects in Africa, Central America, and South America. Recently, Wildland Hydrology developed a master watershed and river restoration plan for the Trail Creek Watershed in Colorado to reduce the accelerated sediment yields following the Hayman Wildfire of 2002. A permit has been issued for the watershed restoration plan to be implemented over 20 years. A similar watershed plan was also developed following a watershed assessment for the basins affected by the Waldo Canyon Wildfire near Colorado Springs in 2012 that destroyed 346 homes. Wildland Hydrology trained federal, state, and local municipalities in the methods to continue implementing the watershed restoration plans.
