Winston is a Java based seismic wave server, which provides data and drawing to the client. The code is open source and is provided free of charge.

Topoflow is a powerful and spatially distributed hydrological model with a user-friendly click interface. Its main purpose is to simulate many different physical processes in a watershed, and its goal is to accurately predict how various hydrological variables will evolve in response to climate forces.

The soil water balance (SWB) model is used to calculate the spatial and temporal variations of groundwater recharge. The SWB model calculates replenishment by combining common geographic information system (GIS) data layers with tabular climate data.

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.

DRAINMOD is a computer simulation model, which simulates the hydrological conditions of poorly drained high water level soil hourly with a long climate record (for example, 50 years). The model predicts the impacts of drainage and related water management practices on groundwater table, soil moisture status and crop yield. The parallel method is mainly used to analyze the hydrological conditions of some types of wetlands to determine whether the wetland hydrological standards meet the requirements of drainage or part of the drainage site. The model is also used to determine the hydropower capacity of the sewage treatment system. The model has been successfully tested and applied to various geographical and soil conditions. Over the past 20 years, the model's capacity has been extended to predict the impact of drainage and water resource management practices on hydrology and water quality in farmland and watershed wide agriculture and woodland.
