Pism-pik model is developed by Potsdam Institute of climate impact to simulate large scale ice sheet shelf system. It comes from the parallel ice sheet model (bueler and brown, 2009). PISM v1.0 is open source with high resolution. Since 2011, it has been widely used as a tool for scientific research.

The soil water balance (SWB) model is used to calculate the spatial and temporal variations of groundwater recharge. The SWB model calculates replenishment by combining common geographic information system (GIS) data layers with tabular climate data.

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

GSFLOW The model is developed by the U.S. Geological Survey to simulate the interaction between surface water and groundwater. The model considers the relationship between meteorological conditions, surface runoff, groundwater runoff and the interaction between surface water and groundwater. It is coupled with the rainfall runoff simulation system PRMs and the three-dimensional finite difference model modflow-2005. The model is suitable for the simulation of non spatial and temporal scales In order to evaluate the impacts of land use change, climate change and groundwater exploitation on surface hydrological process and underground hydrological process.
