Ocean Water Inflow into Kagoshima Bay

Heavy Metals Inflow into Lake Muhazi, Rwanda

Most tropical African lakes are facing pollution problems due to the rapid population growth and industrialization in their riparian communities. Lake Muhazi in Rwanda is one of such lakes which has experienced a dramatic decrease in fish production since the eighties, with also reports of low water transparencies and high turbidities. The lakeshores are now being developed for ecotourism and t...

Assessment of Ilam Reservoir Eutrophication Response in Controlling Water Inflow

In this research, a 2D laterally averaged model of hydrodynamics and water quality, CE-QUAL-W2, was applied to simulate water quality parameters in the Ilam reservoir. The water quality of Ilam reservoir was obtained between mesotrophic and eutrophic based on the measured data including chlorophyll a, total phosphorus and subsurface oxygen saturation. The CE-QUAL-W2 model was calibrated and ver...

Estimating the mean ocean-bay exchange rate of the Chesapeake Bay

[1] A model of the salt balance in the Chesapeake Bay is discussed, which takes into account only time-dependent riverine input and mean ocean-bay exchange. Estimates of (spatial) mean bay salinity are made using two different data sources: a 16 year record of surveys taken by the Environmental Protection Agency’s Chesapeake Bay Program, and a 10 year record of hydrographic sections taken in th...

In situ evaluation of nearshore marine and fresh pore water transport into Flamengo Bay, Brazil

Transport between pore waters and overlying surface waters of Flamengo Bay near Ubatuba, Brazil, was quantified using natural and artificial geochemical tracers, Rn, Cl , and SF6, collected from multi-level piezometers installed along a transect perpendicular to the shore. Eight sampling ports positioned along the length of the piezometers allowed sampling of pore waters at discrete depth inter...
