Water is an important carrier of material movement and transformation in nature. The water cycle is an important material guarantee for the existence of life and economic and social development. Hydrological model is an important means to explore and understand water cycle and hydrological process, and also an effective tool to solve practical problems such as hydrological forecasting, water resources planning and management, hydrological analysis and calculation. At present, the problems of water, water, water and water are increasing. The impact of climate change and human activities on the water cycle and the rise of digital hydrology have created good opportunities for the research, development and application of hydrological models. huge challenge. The hydrological model is a mathematical model constructed for simulating the water cycle process and used to describe hydrophysical processes. It is one of the important methods and methods of hydrological science research. Research and application of hydrological models. It provides people with an important tool and method for scientific understanding and rational use of water resources, and provides an important scientific basis for water resources management and decision-making.

The hydrological model is not only an important part of the field of hydrological science research, but also an important research work in other fields related to the water cycle. The development of hydrological models can be traced back to the inference formula proposed by Mulvaney in 1851. The unit line of Sherman in 1932, the infiltration equation of Horton in 1933, and the evaporation formula of Penman in 1948 are the signs of significant progress in hydrological simulation technology. In the 1960s, the digital revolution triggered by computer technology laid a good foundation and guarantee for the rapid development of hydrological models. The Stanford model of Crawford and Linsley in 1966 was the product of this digital revolution.

The Xinanjiang model came out. Since then, with the rapid development of computer technology, new hydrological models of the basin have emerged. Since the 1960s, the hydrological model has flourished. Hydrologists at home and abroad have developed many well-known conceptual hydrological models, such as Stanford model, HBV model, API model, Xin'anjiang model, SSARR model, ARNO model, SCS model, HEC-1 model, etc. Especially in recent decades, with the rapid development of computer technology, the development and application of hydrological models have been favored and paid attention by the majority of hydrologists. Various hydrological models have sprung up, from conceptual hydrological models. Up to the recently popular distributed hydrological model, various research, development and application work are emerging.

 SWMM - Storm Water Management Model

This topic collects some models including lumped hydrological models and distributed hydrological models. Some of these models can be accessed by jumping to the OpenGMS portal through this website. Other models can be found and accessed on their portals.In addition, this topic also contains some application cases of the model, the most typical is the application case of the SWMM model. You no longer need to download the SWMM model to the machine. Instead of driving the model to run in a complex application interface, you can load and configure the data online. You can run the model and download the calculation results in a few simple steps.
