River Flood Modeling and Remote Sensing Across Scales: Lessons from Brazil
Ayan Santos Fleischmann,João Paulo Lyra Fialho Brêda,Conrado M. Rudorff,Rodrigo Cauduro Dias de Paiva,Walter Collischonn,Fabrice Papa,Fabrice Papa,Mariane Moreira Ravanello +7 more
TL;DR: In this paper, the authors present some recent lessons from Brazil regarding the use of remote sensing (RS) data in improving flood models across scales, showing that more distributed information of cross-sections are needed to achieve better predictions.
Desafios e oportunidades para implementação do hidrograma ecológico
Christopher Freire Souza,Sidnei Gusmão Agra,Rutinéia Tassi,Walter Collischonn,Glauco Kimura Freitas +4 more
TL;DR: Palavras-Chave et al. as mentioned in this paper presented an assessment over the feasibility of applying existing techniques to adopt environmental flows which resemble the natural regime in the country, including the Australian cap, the South Africa reserve and the American adaptive management.
Journal Article
Using TRMM rainfall estimates in hydrological and hydrodynamic modelling of the Amazon Basin
Rodrigo Cauduro Dias de Paiva,Diogo Costa Buarque,Walter Collischonn,Mino S. Sorribas,Daniel Allasia,Carlos André Bulhões Mendes,Carlos Eduardo Morelli Tucci,Marie-Paule Bonnet +7 more
TL;DR: The MGB-IPH as mentioned in this paper is a distributed, physically-based model using the Muskingum-Cunge formulation and a full hydrodynamic model for river routing.
Journal ArticleDOI
Estimating design hydrographs at the basin scale: from event-based to continuous hydrological simulation
TL;DR: In this paper, the authors compared a continuous simulation (CSM) method with an event-based (EBM) method, by forcing a rainfall-runoff model with long precipitation series, and directly analyzing the output discharges.
Journal ArticleDOI
Modelo analítico de qualidade da água acoplado com Sistema de Informação Geográfica para simulação de lançamentos com duração variada
TL;DR: A water quality model coupled with an open source Geographic Information System (GIS) software representing the impacts of large scale pollutant releases, with a systemic view of the entire basin, and simplified tools to deal with typical data scarcity situations is presented.
