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.
Biosphere 3D is an open source project aimed at interactive landscape rendering based on Virtual Earth. The software system supports multiple scales, but it is mainly used to create realistic views from the line of sight level or near ground level. The software is released under the license of MPL and developed by lennal 3D for personal computers. Biosphere 3D was first released in 2007 by the visualization and data analysis department of the Zuse Institute in Berlin. Applications include landscape planning, landscape architecture, visual impact assessment, such as wind farms, power stations, land-use planning, archaeology, urban planning and forestry, enabling them to roam through landscape scenes or nearly reconstructed historical landscapes and gardens. Biosphere 3D, originally funded by the Federal Ministry of education and Research (Germany), was designed as a pure landscape visualization system in the "silvisio" of the R & D project.
