In addition, it allows the researcher more control over the physical processes being modeled. We found that SWAT better replicates field information. Management, making it a better choice when large amounts of data need to be collected and included in the model (such as with larger watersheds like the Guadalupe). The SWAT model allowed the researchers to incorporate more physical data than the ArcHydro model, resulting in a more accurate depiction of the watershed, especially for smaller watersheds like the Blanco.
Both models permitted us to simultaneously study various parameters acting on the watersheds. To test the accuracy of the models and ease of use. Once the models were run, the results were compared to actual field data Data was collected for the Blanco and Guadalupe watersheds and imported into each model. The purpose of the proposed research was to determine which model provided the best representation of a watershed. The models differ in their choice of governing equations and the way each deals withĪctual data that may be collected in the watershed. The models are similar in that each advertises itself as a watershed model with an interface to GlS. This project examined the applicability of two of the mostĬommon models used in hydrological modeling today: ArcHydro (ArcGIS Hydro Data Model) and SWAT (Soil and Water Assessment Tool) model.
