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.

Integrated water flow model is a computer program used to simulate the flow of land surface, surface water and groundwater. It is a rewrite of IGSM software. Iwfm program and source code are provided free of charge. It uses finite element method to simulate groundwater flow. Surface water flow can be simulated by a simple one-dimensional flow network or by moving wave method. Allows users to run models for a specific period of time while editing input files. Iwfm simulates four land use categories: agriculture, urban, native vegetation and riparian vegetation. Land use area is divided into a time series with corresponding evapotranspiration rate and water management parameters. In the agricultural and urban land use categories, iwfm applies surface water and groundwater according to a specific ratio, and can selectively adjust surface water and groundwater to meet water demand.

ARPS model is a non-static equilibrium regional forecast system developed by the storm analysis and Prediction Center of the University of Oklahoma. ARPS model adopts generalized terrain coordinate system, arakawa-c staggered horizontal grid and second-order leapfrog leaping time integration scheme, including cloud microphysical process, sub grid scale turbulence and other physical processes. ARPS model is suitable for small and medium-sized and storm scale weather systems, such as tornado, supercell storm, etc. ARPS model is mainly aimed at non energetic high-resolution regional forecast system of storm scale, including variational assimilation of real-time data, forward prediction and post-processing module.

MSSW is a computer program to simulate the movement of solute in water. The program solved Richards' saturated unsaturated water flow equation and solute transport convection dispersion equation numerically.

SPARE:WATER It is a spatial decision support system for estimating water consumption of agricultural production system. It is a stand-alone software application that integrates a database for mathematical models and graphical user interfaces (GUIs) for estimating crop water requirements. The software realizes the function of GIS, which is used to manage spatial data based on open source spatial database.
