Fracionamento do fósforo em sedimentos de reservatórios tropicais semiáridos
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA SANITÁRIA, 2017-02-22)
The reduction of external loads of phosphorus (P) is the main action to promote the reduction of eutrophication in lakes. However, the elimination of these sources is not always sufficient for the recovery. This occurs ...

Controle do fósforo em reservatório eutrofizado no semiárido: experimento em microescala com a técnica "flock & lock".
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Ambiental, 2017-06-12)
Controlling an input of external sources of phosphorus into the aquatic body as well as

eutrophication. Studies show that the joint action ...
A qualidade da disponibilidade hídrica do reservatório de Cruzeta na região semiárida tropical em evento de seca prolongada
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Ambiental, 2017-11-23)
In the Brazilian semi-arid region, many reservoirs are exposed to high evaporation rates and water deficit effects, causing a significant decrease in their water volume during the extended drought season, achieving to so ...
