CryoSat-2 Altimetry Applications over Rivers and Lakes
Monitoring the variation of rivers and lakes is of great importance. Satellite radar altimetry is a promising technology to do this on a regional to global scale. Satellite radar altimetry data has been used successfully to observe water levels in lakes and (large) rivers, and has also been combined with hydrologic/hydrodynamic models. Except CryoSat-2, all radar altimetry missions have been op...
متن کاملLarge - scale hydrologic and hydrodynamic modelling of the Amazon River basin 2 3 4 Rodrigo
22 23 In this paper, a hydrologic/hydrodynamic modelling of the Amazon River basin 24 is presented using the MGB-IPH model with a validation using remotely-sensed 25 observations. Moreover, the sources of model errors by means of the validation and 26 sensitivity tests are investigated and the physical functioning of the Amazon basin is 27 also explored. The MGB-IPH is a physically-based model ...
متن کاملHydrologic responses of watershed assessment to land cover and climate change using soil and water assessment tool model
Predicting the impact of land cover and climate change on hydrologic responses using modeling tools are essential in understanding the movement and pattern of hydrologic processes within the watershed. The paper provided potential implications of land conversions and climate change scenarios on the hydrologic processes of Muleta watershed using soil and water assessment tool model. Model inputs...
متن کاملSensitivity Analysis of Brown Model Waveform in Radar Altimetry
In satellite altimetry (radar altimetry), the altimeter emits a pulse, with known power, to the earth surface and receives it back continuously to determine of the sea surface height. The time series of the mean returned power is recorded individually at satellite as the so-called waveform. Analytical model for the waveform is first introduced by Brown, which consists of six parameters: signif...
