TL;DR: In this article, a hydrologic/hydrodynamic modeling of the Amazon River basin is presented using the MGB-IPH model with a validation using remotely sensed observations.
Journal ArticleDOI
Daily hydrological modeling in the Amazon basin using TRMM rainfall estimates
TL;DR: In this article, the authors evaluate the rainfall estimates of the Tropical Rainfall Measuring Mission (TRMM) satellite over the Tapajos river basin, a major tributary of the Amazon.
Journal ArticleDOI
The MGB-IPH model for large-scale rainfall—runoff modelling
TL;DR: In this paper, a large-scale distributed hydrological model is described, which has been used in several large river basins in Brazil, including the Taquari-Antas River basin.
Journal ArticleDOI
Large scale hydrologic and hydrodynamic modeling using limited data and a GIS based approach
TL;DR: In this article, a large-scale hydrologic model with a full one-dimensional hydrodynamic module to calculate flow propagation on a complex river network is presented, which is capable of simulating a wide range of fluvial processes such as flood wave delay and attenuation, backwater effects, flood inundation and its effects on flood waves.
Journal ArticleDOI
A direction dependent least-cost-path algorithm for roads and canals
TL;DR: A least-cost-path algorithm developed to find the best path given the topography, the start and end-points of the linear feature (canal or road) and a function relating slope, distance and cost is presented.
