Abstract
Based on "3S" (RS, GIS, GPS) technologies and completely distributed design ideas, a new algorithm of the Distributed Snowmelt Concentration Model is designed and built after study the Distributed Snowmelt Runoff Model. It has spatiotemporal features and takes the DEM data, which with high resolution, as a foundation and picks up the hydrological factors, such as slope, gradient, direction of flow, collecting time, drainage network etc., and the algorithm is simple to understand and to implement, requiring only a few tens of code lines and running faster. So the algorithm will be versatile. Meanwhile, a new conception "Period Unit of Time-step" is put forward in this paper, and the algorithm procedure is fully detailed too. After the model applied in the representative study area, Juntanghu Basin, which located in the North-Tianshan Mountains, China, and contrasted with the homologous observed data obtained in the same field, the simulation results show clearly that the Distributed Snowmelt Concentration Model and its algorithm is very good.
