Abstract
• L-THIA (Long-Term Hydrologic Impact Analysis) is a mature model available as a spreadsheet, a web-based spatial model and as an add-in to the popular geographic information system (GIS) software system ArcGIS 10. • The model generally has a method to determine an area of analysis such as a watershed, and then populates the watershed with data on soil and landuse. • The model generally requires precipitation data for a long term and uses assumptions about the relationship between landuse, soil, and the chemistry of surface runoff passing across the various landscapes. • Input data are landuse and soil map layers and long-term precipitation
