Welcome to the Object Modeling System (OMS), a pure Java, object-oriented modeling framework. OMS allows model construction and model application based on components. This is a collaborative project active among the U.S. Department of Agriculture and partner agencies and organizations involved with agro-environmental modeling. OMS v3.+ is a highly interoperable and lightweight modeling framework for component-based model and
simulation development on multiple platforms.
The OMS3 framework goal is to provide features to the modeler to make easy to create, inter-operable, scalable, and unburdened models that take full advantage of contemporary computing, management, and infrastructure technologies while keeping it simple intuitive for users.
PRMS is a modular, deterministic, distributed-parameter modeling system developed to evaluate the impacts of various combinations of precipitation, climate, and land use on streamflow, sediment yields, and general basin hydrology.
AgES is a modular, spatially explicit hydrological system implementing hydrological processes as process components. AgES operates at various temporal and spatial aggregation levels throughout the watershed.
