Methods of Processing Hydrometeorological Data Based on Tinoasa – Ciurea Representative Basin

Abstract

This paper summarizes the data processing methods derived from observations and measurements at Tinoasa Ciurea Representative Basin for the year 2013. This basin was chosen as a case study in this paper because it uses both classical and modern equipment (sensors for recording water level, solar radiation sensors and sensors for determining evaporation) in order to monitor hydrometeorological phenomena. Also, this basin is considered to be representative to all of the eastern plateau areas in Romania. The study aims at analyzing monitored meteorological parameters during the year 2013 within the basin and their influence on the formation of runoff, highlighting the main aspects of the flow and their role in the propagation and warning of dangerous hydrological phenomena. The methodology was based on the use of GIS technology and on numerical flow simulation models. Using GIS technology for characterizing and analyzing the study area brings forth its main software packages such as ArcGIS and the modalities for the implementation of this technology in small river basins. Equipping this basin with an automatic weather station (including all types of radiation sensors) and sensors for level determination makes it a warning basin in the case of dangerous hydrological phenomena occurrence. In conclusion, the study targets the influence that physico-geographical and generator factors have on the formation of runoff in small river basins.
