Water Level Temporal Variation Analysis at Solimões and Amazonas Rivers

摘要: The Amazonas and Solimoes rivers their tributaries represent the largest river system in world. It involves an extremely high water volume, discharging into Atlantic Ocean approximately 20% of total volume whole main factor which influences level is intensive rainfall over those regions, consequence humid characteristic tropical climate. This paper intended to show variation along both as a direct three different kinds ocean-atmosphere interactions: El-Nino, La-Nina inter-hemispheric Sea Surface Temperature – SST gradient Ocean. For this study it has been used 13 limnimetric stations where geodetic heights were derived from GPS observations combined with GEOAMA (Amazon geoid model), developed at Laboratory Topography Geodesy (LTG). orthometric height surface was derived. measurements 1993 through 2006 analysed for greatest flood lowest ebb periods, June October respectively. allowed calculate mentioned period.
