Confluence
In geography, a confluence (also: ''conflux'') occurs where two or more flowing bodies of water join to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the source of a river of a new name (such as the confluence of the Monongahela and Allegheny rivers at Pittsburgh, forming the Ohio); or where two separated channels of a river (forming a river island) rejoin at the downstream end. Scientific study of confluences Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern ownstream of confluencesof increasing stream flow and decreasing s ...

Headwaters
The headwaters of a river or stream is the farthest place in that river or stream from its estuary or downstream confluence with another river, as measured along the course of the river. It is also known as a river's source. Definition The United States Geological Survey (USGS) states that a river's "length may be considered to be the distance from the mouth to the most distant headwater source (irrespective of stream name), or from the mouth to the headwaters of the stream commonly known as the source stream". As an example of the second definition above, the USGS at times considers the Missouri River as a tributary of the Mississippi River. But it also follows the first definition above (along with virtually all other geographic authorities and publications) in using the combined Missouri—lower Mississippi length figure in lists of lengths of rivers around the world. Most rivers have numerous tributaries and change names often; it is customary to regard the longest t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Provinces Of The Philippines
In the Philippines, provinces ( fil, lalawigan) are one of its primary political and administrative divisions.

Each province is governed by an elected legislature called the Sangguniang Panlalawigan and an elected governor. The provinces are grouped into seventeen regions based on geographical, cultural, and ethnological characteristics. Thirteen of these regions are numerically designated from north to south, while the National Capital Region, the Cordillera Administrative Region, the Southwestern Tagalog Region, and the Bangsamoro Autonomous Region in Muslim Mindanao are only designated by acronyms.
