The recess program is used to determine the decline index and determine the main decline curve from the analysis of runoff records.

Dr3m is a distributed rainfall runoff model, which takes rainfall as input to calculate the rainstorm runoff through drainage pipeline or natural river. The detailed simulation of the rainstorm runoff period selected by the user is provided. The calculation of soil moisture is carried out every day during the rainstorm period. A watershed can be expressed as slope flow, channel and reservoir section, which together describes the drainage function elements of the basin. This model is usually used to simulate small urban basins. The flow and base flow in soil are not simulated, snow and snow melting are not simulated.

Scops3d is a software used to analyze the stability of three-dimensional slopes in the whole digital landscape.

ALMANAC model is a practical model, which was first used as a part of EPIC model to simulate the decline of land productivity caused by soil erosion. ALMANAC model can simulate crop growth process and soil water balance process, including: light interception by crop leaves, biomass accumulation, biomass distribution in different organs of crops, full utilization of water by crops, absorption of nutrients, and constraints of environmental factors on crop growth process, such as water stress, temperature stress and nutrient stress. The ALMANAC model provides a util editor. This is a very friendly interface database editing program, can directly provide users with the input variable database prompt operation.

The seismic information distribution system (EIDs) provides a method to receive the seismic data on the Internet in near real time. The EIDs replaces the seismic data distribution system (QDDS), and provides the output message in the format of multi-dimensional data set or eqxml.
