The SBEACH numerical simulation model was developed at the U.S. Army Engineer Waterways Experiment Station, Coastal and Hydraulics Laboratory (CHL). It simulates cross-shore beach, berm, and dune erosion produced by storm waves and water levels.

AGricultural Non-Point Source Pollution Model (AGNPS) is a joint USDA - Agricultural Research Service (ARS) and - Natural Resources Conservation Service system of computer models developed to predict non point source pollutant loadings within agricultural watersheds.

The Marine Integrated Decision Analysis System (MIDAS) was developed to assist the Marine Managed Areas (MMA) users and managers in understanding the critical factors that influence MMA effects so that they can plan accordingly, to estimate likely MMA effects based on the ecological, socioeconomic and governance conditions, and finally, to advise management plan revisions that will result in optimization of outcomes and outputs.

UNIBEST (UNIform Beach Sediment Transport) is a software package which contains tools for the computation of sediment transport. The package consists of three models:

• UNIBEST-CL+ can be used to compute sediment transport and coastline changes along uniform sandy coasts as a result of natural forces or human interference.
• UNIBEST-DE can be used to compute dune erosion during storm events.
• UNIBEST-TC can be used to compute cross-shore profile changes during normal conditions (e.g.

Google Earth (free version) Intended for personal, non-commercial use, the free version of Google Earth sends you on an interactive, 3D exploration of the planet through terabytes of aerial and satellite imagery.

TOA-MD is a simulation model designed to carry out multi-dimensional impact assessment of agricultural and aquaculture technologies, analysis of ecosystem service supply, and climate impact and adaptation assessment.

The Automated Geospatial Watershed Assessment (AGWA) Tool is a GIS-based watershed management tool that parameterizes and runs two watershed models, KINEROS2 and SWAT. AGWA is designed to provide qualitative estimates of runoff and erosion relative to landscape change.

N-SPECT helps coastal managers and local officials predict potential water quality impacts to rivers and streams from nonpoint source pollution and erosion. Users first enter information about their area (land cover, elevation, precipitation, and soil characteristics) to create the base data layer.

The Nature Conservancy (TNC) has a vested interest in helping countries develop science-based Protected area networks and has pledged support through the development of country-driven National Implementation Support Programs (NISPs).

The SLEUTH model, also known as the Clarke Cellular Automata Urban Growth Model or as the Clarke Urban Growth Model, is intended to simulate urban growth in order to aid in understanding of how expanding urban areas consume their surrounding land, and the environmental impact this has on the local environment.
