Exams is an interactive software application for developing aquatic ecosystem models and rapidly assessing the processes, transport and exposure concentrations of synthetic organic chemicals, including pesticides, industrial materials and waste disposal sites. Exams contains an integrated database management system (DBMS), which is specially used to store and manage the project database required by the software. User interaction is provided by a fully functional command line interface (CLI), the use of flexible help menus, an online data dictionary, and a cli user guide, and maps the ability to check output data.

Esap-95 software package contains a series of site salinity modeling software programs for analyzing and predicting soil salinity information. Esap-95 software package currently contains three software programs: esap-rssd, ESAP calibrate and ESAP saltmapper. The esap-rssd program is designed to produce the best results of soil sampling designs from bulk soil conductivity surveys. Esapcalibrate program is designed to estimate stochastic (regression model) and deterministic (soil) theoretical basis) calibration equations; i.e. These equations are eventually used to predict the spatial values of one or more soil variables, derived from electrical conductivity measurements. ESAP saltmappercheng program can be used to produce high-quality 1D or 2D graphics, output electrical measurement data or predict soil variables.

Geosfm hydrological model is studied by the center for earth resources observation and Science (EROS) of the U.S. Geological Survey (USGS). Its biggest feature is that the satellite remote sensing precipitation products can be directly used as the driving parameters of the model. The geosfm hydrological model has been applied to the Nile River Basin in Africa, Mekong River in Asia and bagmati River Basin in Nepal. Geosfm can create a common visual environment to monitor hydrogeological conditions in a wide range of areas, including topographic analysis, data assimilation and time series processing, and display the monitoring results.
