Evolution is a natural phenomenon to most software systems because of its continuous function extension and system maintain requirements. Many software systems which were developed based on Model1 have been found to have many disadvantages, and these shortcomings baffle the reuse of the software systems. In this paper, a software-reuse method is being put(More)
In the distributed hydrological simulations for complex mountain areas, large amounts of meteorological input parameters with high spatial and temporal resolutions are necessary. However, the extreme scarcity and uneven distribution of the traditional meteorological observation stations in cold and arid regions of Northwest China makes it very difficult in(More)
