Spatial Processes in HYdrology (SPHY) model

Version 2.2

The Spatial Processes in Hydrology (SPHY) model is a hydrological modeling tool suitable for a wide range of water resource management applications. SPHY is a state-of-the-art, easy to use, robust tool, that can be applied for operational as well as strategic decision support. The SPHY model has been applied and tested in various studies ranging from real-time soil moisture predictions in flat lands, to operational reservoir inflow forecasting applications in mountainous catchments, irrigation scenarios in the Nile Basin, and detailed climate change impact studies in the snow- and glacier-melt dominated the Himalayan region.

SPHY model concepts

Changes with respect to version 2.1
Glaciers in version 2.1 and 2.0 were not mass conserving. In previous versions they were implemented as a fixed mass generating glacier melt using a degree day factor. This new release accounts for rainfall and snowfall onto the glacier, accumulation and melt of snow, and redistribution of ice from the accumulation to the ablation zone. These modifications allow glaciers to retreat over time if the melt rate is higher than the accumulation rate. Details and an example application can be found in Concepts and application of the mass conserving glacier module.
