摘要: [1] Terrestrial water storage in the Amazon basin and its surrounding areas is studied by exploring instantaneous measurements of distance changes between two satellites from GRACE mission. The surface channels floodplains can be significant weighing total storage. Its magnitude as large soil moisture perturbing motions to a detectable amount on-board instrument. river runoff routing simulations indicate effective velocity throughout over years about 30 cm/s with seasonal change. lower velocity, during rising stages peak season, faster falling stages, are delineated observations. backwater effects may impact such change on overall flow velocity. Direct assimilation tracking data contribute land dynamic processes resolving time scale transport rivers streams.
