Hydrologic modeling is at the heart of modern hydrology, supplying rich information that is vital to addressing resource planning, environmental, and social problems. Recognizing the need for a broad, comprehensive overview of the various types of models, we have have compiled an up-to-date inventory of several highly popular and useful models to produce this groundbreaking reference. The models are listed under various categories on the top menu. To avoid duplication, models that fit in more than one category will be listed only one category. The site visitor is therefore encouraged to peruse through the different categories when looking for information about a specific model.
The effort to develop this database was started in 1999 as a collaborative effort between Louisiana State University and the Bureau of Reclamation. Developers of well known models were contacted by Dr. Vijay P. Singh, Dr. Donald K. Frevert and several other Bureau of Reclamation staff members. Each developer was asked to fill out a questionnaire providing basic information including the capabilities of their model, input requirements, output information, assumptions, hardware requirements and contact information. The questionnaires were originally posted on a Bureau of Reclamation website, but in 2007 the website was moved to the Texas A&M domain to facilitate support and maintenance. In 2018, the site was revamped after years of non-maintenance, given a new permanent host, the structure and layout improved and more content included.
The inventory, its origin and development are described in “Singh, Vijay P., et al. “The Hydrologic Modeling Inventory: A Cooperative Research Effort.” Watershed Management and Operations Management 2000. 2000. 1-8″ available on https://doi.org/10.1061/40499(2000)60.
