Abstract
The surveillance and management of water resources in the Carpathian basin of Romania involve the knowledge of snow pack evolution and the snow cover water equivalent estimation in different phases of the snowmelt-runoff season. The paper describes the practical methods developed in the Remote Sensing and GIS Laboratory of the National Meteorological Administration and presents the results obtained for basin snow cover area extent and snowline elevation determination, new snowfall identification, snow cover depletion curves, etc. The method for the evaluation of the water resources stored in the snow pack is based on the use of data from two investigation levels: satellite images and ground information. A complex georeferenced database, consisting of medium and high resolution satellite data (NOAA-AVHRR, TERRA MODIS, LANDSAT-TM, SPOT-XS), spatial terrain information derived from Digital Elevation Models (DEM) and other exogenous data (maps and ground measurements) was designed and implemented on PC-based computing systems. The GIS developed for the snow cover water resources management includes information on topography, land vegetation cover, land use, soil type, and hydro-meteorological parameters that could be used as separate layers or be interconnected in order to extract the necessary information for a correct and accurate estimation of the snow pack conditions and snow cover water storage during the winter-spring period. This methodology was applied to the main Carpathian catchments in Romania and two examples for the Arges and Bistrita catchments are presented The results obtained using this combined method allowed the permanent monitoring of the
