    Abstract: Physicochemical parameters could help to reduce or otherwise contribute to the growth and survival of plankton biotopes in the water bodies. This study investigated the physicochemical parameters and plankton biotopes of Ntawogba creek in Port Harcourt, River state. Water samples were collected from five stations representing upstream and downstrea... Show More

    Abstract: The study of the rainfall-runoff relation on annual and monthly scales is based on the hydrological data measured in various stations of the Kouilou-Niari basin. The parameters of the rainfall-runoff modeling were obtained with satisfaction by today’s standards of quality. The objective of this study is to evaluate the impacts of the climate change...

    Abstract: Beginning in the mid 20th Century the Chesapeake Bay began to show the first signs of eutrophication, with seasonal depletion of free oxygen in bottom waters (hypoxia). Eutrophication is driven largely by external loading of phosphorus (P) and nitrogen (N). These nutrients maintain high levels of phytoplankton productivity and subsequent transfer o... Show More

    Abstract: The Lake Chad basin, one of Africa’s oldest river basin has shrank to one-tenth of its original size. The environmental degradation that had occurred in the basin over the years has had direct impact on the livelihood of people in the region. The problem in the Lake Chad Basin has also constituted social risks to populations of the region resulting... Show More
