Hydrologists use experimental watersheds to collect detailed data with rich space–time coverage of many storages and fluxes within the hydrologic cycle. Such watersheds have seen the discovery of new hydrologic processes, such as the positive feedback between rising water tables and groundwater flow (bishop, 1991).

Hydrological models are simplified, conceptual representations of a part of the hydrologic cycle. They are primarily used for hydrological prediction and for understanding hydrological processes, within the general field of scientific modeling. Two major types of hydrological models can be distinguished: models based on data.
