A detailed multi-disciplinary field study was conducted in a small subtropical creek in Eastern Australia. Hydraulic and ecological measurements were conducted simultaneously in the river mouth to assess the complexity of a small estuarine system, and the interactions between hydraulic engineering, environmental issues, biology and ecology. The results provide an unique and original snapshot of...

Lake Tinco, which lies on the Orinoco floodplain, passes through four seasonal phases (filling, through-flow, drainage, and isolation), during which the lake volume changes 20-fold. During filling and through-flow, when the lake is inundated by river water, floating grasses (Paspalum repens) and phytoplankton grow rapidly, causing depletion of inorganic N and P between inflow and outflow, altho...

our plankton and semi-plankton collections from twelve floodplain lakes (beels) of majuli river island, upper assam reveal 124 rotifer species (32 genera and 17 families); these merit biodiversity value as ~52.0% and ~30.0% of species, ~68.0 and ~45.0% of  genera and ~74.0 and ~65.0% of the families of the phylum known from northeast india (nei) and india, respectively. two species are new to i...

Small dams for hydropower have caused widespread alteration of Central American rivers, yet much of recent development has gone undocumented by scientists and conservationists. We examined the ecological effects of a small hydropower plant (Doña Julia Hydroelectric Center) on two low-order streams (the Puerto Viejo River and Quebradon stream) draining a mountainous area of Costa Rica. Operation...

Three river basins, i.e., the Yangtze river, the Mississippi river and the Loire river, were presented as case studies to explore the association among atmospheric circulations, moisture exports and extreme precipitations in the mid-latitudes. The major moisture source regions in the tropics for the three river basins are first identified using the Tropical Moisture Exports (TMEs) dataset. The ...

BACKGROUND The Araguaia River basin runs through the states of Goiás, Mato Grosso, Tocantins, and Pará, covering 373,000 Km(2), mostly within the Brazilian Cerrado. The region has a wide variety of wetlands. The climate is characterized by high temperatures and strongly seasonal precipitation. There are two well defined seasons: the dry season (winter-spring) and the rainy season (summer- fall)...

The importance of organic carbon and inorganic nutrients in controlling bacterial production was investigated in two tropical lowland rivers draining undisturbed forested catchments. Glucose (C), ammonium (N), phosphate (P), leaf leachate, and algal leachate were added alone or combined to water collected from one clear-water (Cataniapo) and one black-water (Autana) river of the Middle Orinoco ...

a r t i c l e i n f o The Upper Rio Chagres drains 414 km 2 of steep, mountainous terrain in central Panama. A tropical air mass thunderstorm on 10 July 2007 produced a flood across the basin that peaked at 720 m 3 s − 1 at a headwaters gage draining 17.5 km 2 and 1710 m 3 s − 1 at a downstream gage draining 414 km 2. The storm also triggered numerous landslides in the upper basin, which facili...
