Estuaries are places where freshwater rivers and streams flow into the ocean, mixing with the seawater. A wide variety of birds, fish, and other wildlife make estuaries their home. People also live, fish, swim, and enjoy nature in estuaries and the lands surrounding them. On September , the Environmental Protection of International River Basins (EPIRB) project will conduct training and launch the new groundwater monitoring well, equipped with modern electronic devices in the Aknashen village of Ararat valley of Armenia. The San Bernard River and Cedar Lakes Estuary is one of three minor estuaries located on the upper-mid Texas coast in Brazoria County between Matagorda Bay and Galveston Bay. It includes Cedar Lakes, Cowtrap Lake, and the lower reaches of the San Bernard River, covering a surface area of 3, acres (1, ha) with an average depth of feet. Drainage basins of the principal oceans and seas of the world. Grey areas are endorheic basins that do not drain to the oceans. Ocean basins. The following is a list of the major ocean basins: About % of the world's land drains to the Atlantic Ocean. [citation needed] In North America, surface water drains to the Atlantic via the Saint Lawrence River and Great Lakes basins, the Eastern.

Conclusions. According to the geomorphology and physiography classification scheme for estuaries proposed by Pritchard () and presented in Kennish (), Great Lakes estuaries can be classified as Type A: drowned river valleys or by: Lake Caddo is one of Texas' few non-oxbow natural lakes and is the 2nd largest natural lake in the South, before it was artificially altered by a dam constructed by the Gulf Refining Corporation near Mooringsport, Louisiana in , in order to raise the water level to accommodate drilling equipment when oil was found under the water. Abstract. The U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental Protection, Massachusetts Department of Conservation and Recreation, and Tufts University, completed a study of bottom-sediment quality in selected lakes, rivers, and estuaries in the Mystic River Basin, –;; More than bottom-sediment grab samples and 8 bottom-sediment . Ponds, lakes, rivers, and estuaries are believed to be the same thing for they all carry water. However, many are mistaken for the differences in each system of water flow is what allows water to be carried throughout the land. A pond is usually mistaken to be a form of lake in a smaller scale, that is hardly true.

In addition to providing economic, cultural and ecological benefits to communities, estuaries deliver invaluable ecosystem services. Ecosystem services are fundamental life-support processes upon which all organisms depend (Daily et al., ). Two ecosystem services that estuaries provide are water filtration and habitat protection. An estuary is an area where a freshwater river or stream meets the ocean. In estuaries, the salty ocean mixes with a freshwater river, resulting in brackish sh water is somewhat salty, but not as salty as the ocean. An estuary may also be called a bay, lagoon, sound, or slough. Water continually circulates into and out of an estuary. Tides create the largest flow of saltwater. Definition and classification of estuaries arnoldo valle-levinson University of Florida This chapter discusses definitions and classification of estuaries. It presents both the classical and more flexible definitions of estuaries. Then it discusses separate classifications of estuaries based on water balance, geomorphology, water columnFile Size: KB. With a drainage area of 7, square miles, the Toledo Bend Reservoir conserves water for municipal, industrial, agricultural, and recreational purposes and stretches for well over river miles. The lake has a conservation surface area of , acres and a shared storage capacity of 4,, acre-feet at the conservation pool elevation of.
