Introduction
• Riparian areas are an important natural resource that are rich in biodiversityand ecological and hydrological functions. These ecosystems contain specificvegetation and soil characteristics that play important roles in protecting waterquality and stream ecosystem health and are very responsive to changes inland management activities. Delineating and quantifying riparian areas is anessential first step in monitoring, planning, management, and modeling forthese areas.
• USDA Forest Service supports the development and implementation of anational context framework with a multi-scale approach to define riparian areasutilizing free available national geospatial datasets.

Introduction
• In 2015, the Forest Service Watershed, Fish, Wildlife, Air, & Rare Plants(WFWARP) staff and Rangeland Management & Vegetation Ecology(RMVE) staff funded the development and implementation of the RiparianBuffer Delineation Model (RBDM) to obtain a national inventory of riparianareas.
• This product would inform the Agency on national riparian resource conditionswith multi-scale approach, and support other landscape projects such as theTerrestrial Condition Assessment (TCA), Watershed ConditionClassification (WCC), and Forest to Faucet.

Model Parameters
Direct impact:
❑ Flood value.
❑ Stream positional inaccuracies.
❑ DEM spatial resolution.
❑ Sampling distance.
Need to be considered:
• Stream classification and stream order.
• Hydrologic data. 50-year vs 100-year debate.
• Watershed scale.
• Inherited errors from input data.
