Abstract Extensive floodplains throughout the Amazon basin support important ecosystem services and influence global water carbon cycles. A recent change in hydroclimatic regime of region, with increased rainfall northern portions basin, has produced record-breaking high levels on River mainstem. Yet, implications for magnitude duration floodplain inundation across remain unknown. Here we leverage state-of-the-art hydrological models, supported by in-situ remote sensing observations, to show...
The Amazon region has rivers of great contribution to the biodiversity balance and regional landscape.Among them, stand out are Negro River -the most extensive, -with largest volume, Purus -a fish supplier, Madeira modified.Flooding in is often widespread sometimes severe for those who live very close rivers, yet urban areas more socially impacted than rural areas, as flooding part riverside population's daily life.Flood forecasting models important composing extreme event alerts well...
The current scenario of water scarcity evidences the need for an adequate management resources. In karstic regions, flow through fractures significantly increases infiltration rate, which explains small number rivers and importance groundwater urban supply. Therefore, balance is necessary since it may aid decision making processes guide projects. objective this paper was to perform a watershed situated in region quantifying infiltration, runoff evapotranspiration. study area located near...
Airports consume significant amounts of water which can be compared to the volume consumed by mid-size cities, thus practices aimed at reducing consumption are important and necessary. The objective this study was assess reuse potential sewage effluent produced a international airport for nursery irrigation. treatment system consisted facultative pond followed constructed wetland, were monitored during one hydrological year parameters COD, pH, solids, nitrogen, phosphorus Escherichia coli...
Abstract In the current scenario of Brazilian low water availability, financial compensation funded by hydroelectric power plants (HPPs) represents an important tool for management and conservation hydrographic basin. This payment could be applied to mitigate HPP's greatest problems such as scarcity reservoir silting. We propose apportionment proportional average flow provided each municipality within catchment area size flooded its reservoir. The was obtained through balance between...
Historiquement les valeurs journalières de débit sont obtenues manière indirecte en appliquant une courbe tarage aux correspondantes hauteur d’eau. Mais pour beaucoup stations du bassin amazonien le mesuré est affecté par un effet barrage hydraulique dû à l’influence variable entrant d’un affluent et l’on ne peut plus appliquer simple hauteur/débit. Pour prendre compte cet mascaret, nous avons créé la station Manacapuru sur Río Solimoes série débits journaliers l’équation Manning hauteurs...

The magnitude of the Amazon basin, associated with geological, geomorphological and hydrological factors, as well distribution rainfall, contribute to existence large rivers, both in extension flow, such Negro Solimões which are selected be evaluated this study.Manaus city is bathed by river, near confluence two water level river controlled level.This study proposes analyse a project named River Flood Warning System that presents or stage forecast about Geological Survey Brazil Manaus since...
Flood and ebb processes are common events in any hydrological system.In some cases, due to natural or anthropogenic conditions, such can take place an extreme manner, causing a lot of damage the population.In 2021, several municipalities Amazon basin, rivers reached levels higher than maximum observed until then, making this year biggest flood entire history monitoring.Most Amazonian have high annual pulse floods, as result precipitation period upper part their large basins.Most floodplains...
