Discharge Forecasts in Mountain Basins Based on Satellite Snow Cover Mapping
نویسنده
چکیده
Depletion curves of the areal extent of snow cover are shown to be basic information in a snowmelt-runoff model. Originally developed in European mountain basins, the procedure is now applied to simulate the runoff in the Rocky Mountains with the use of the Landsat imagery and air temperature data. The method requires a proper assessment of the recession coefficient of discharge in a given basin. It is adaptable to operational short-term forecasts of discharge and to evaluation of seasonal runoff volumes.

Remote Sensing Based Retrieval of Snow Cover Properties Case Study (Shirkooh Mountain Yazd, Iran)
Snow cover area is one of the most important criteria to calculate snow melt runoff. This can have an effect on the biology of the plant and the environment of a region. Using the catchment basin physical characteristic to calculate snow cover area is a conventional method, though its accuracy is not good enough. Most of the useful methods in calculating snow cover area are based on satellite i...

متن کاملDistributed mapping of snow and glaciers for improved runo modelling
Runo in glacierized alpine basins results from both seasonal snow cover and glacier melt. In this paper we present a case study for an improved runo modelling of the basin Massa-Blatten, 196 km, 1447±4191 m a.s.l. Using high resolution satellite sensors, it is possible to separately map snow cover and glacier areas. From the satellite data we derive depletion curves of snow covered areas in s...
