PHREEQC Model
Author: 

PHREEQC is a computer software (Parkhurst and appelo, 1999) for the calculation of various low-temperature hydrogeochemical reactions. PHREEQC, based on the ion linked water model, can (1) calculate the species and saturation index of matter formation; (2) simulate geochemical inversion process; (3) calculate batch reaction and one-dimensional migration reaction. In addition, PHREEQC coupled with multi-component solute transport model can generate PHAST, a three-dimensional reaction transport simulator for simulating groundwater flow system. PHREEQC is also useful in the investigation of unpolluted and polluted environment, laboratory, field and regional investigation. PHREEQC can investigate various natural and human influenced environmental geochemical reactions, including acid mine water discharge, radioactive waste isolation, pollutant migration, nutrient enrichment, aquifer natural and artificial restoration, aquifer reserve recovery, drinking water treatment, indoor experiment and regional aquifer system. PHREEQC has two graphical user interfaces available. Phreeqcl is a screen driven interface that provides a descriptive explanation for each data item (Charlton and Parkhurst, 2002). PHREEQC used in windows is a row editing object interface. Its additional input features enable it to generate graphic simulation results (post, 2004).

WEAP model (water evaluation and planning)
Author:  Stockholm Environment Institute's U.S. Center.

The challenge of freshwater management is becoming more and more common. The allocation of limited water resources between agricultural, urban and environmental uses requires a complete combination of water supply, water demand, water quality and ecological considerations. By integrating these elements, weap is committed to building a highly functional and operational integrated water resources planning system. WEAP model has the following characteristics:

Lpjml model (Lund Potsdam Jena managed land)
Author: 

Lpjml model is developed by LPJ, which is a dynamic global vegetation model (DGVM). It is designed to simulate the global terrestrial carbon cycle and the response of carbon and vegetation patterns to climate change. As carbon and water cycles are closely linked, it is quickly extended to simulate the terrestrial water cycle.

SRM model (snowmelt runoff model)
Author: 

SRM snowmelt runoff model is a typical representative of empirical models. It was proposed by Swiss scientists martinec and Rango in the early 1980s. It has been tested and applied in more than 100 watersheds in more than 20 countries. Due to the simplicity and high accuracy of SRM model, scholars have carried out in-depth research and achieved more results. Rango has modified the parameters of SRM model for many times, so that the model can be more widely extended; Brubaker corrected the improper extraction of degree day factors; Im merzeeel and others used the SRM model to study the impact of climate change on Asian water tower; SRM has been widely used to study the impact of climate change on Asian water tower In the Ganges River Basin, it is found that the model is not limited by basin scale and height, which indicates that the model can not only be applied at small watershed scale. Domestic scholars focus on SRM Ma Hong applied the model to Gongnaisi River Basin in the Western Tianshan Mountains and achieved good results, which showed that the model had a good application prospect in the inland arid areas of Western China; Feng Xuezhi used the improved SRM model to simulate the daily discharge of Manas River Basin; Wang Jian focused on the study of GIS and remote sensing data in Alps mountain watershed The key parameters and factors in SRM model are selected.
