The Iowa Cubs Confluence is located behind Principal Park at Sec Taylor Field where the Raccoon River and the Des Moines River meet.
This site is also home to our Iowa Cubs and the location of some major flooding in 1993.
Confluence - Confluence, in geography, describes the meeting of two or more bodies of water. It usually refers to the point where a tributary joins a more major river. A notable confluence is the merging of the Monongahela and Allegheny Rivers. This merging point is the beginning of the Ohio River, thus forming a confluence in Pittsburgh. Then the Ohio meets the Mississippi for another notable confluence.
The Raccoon and Des Moines rivers are just not as notable as the above example.
River - a large natural stream of water (larger than a creek). A river is a large natural waterway. It is a specific term in the vernacular for large streams, stream being the umbrella term used in the scientific community for all flowing natural waterways. In the vernacular, stream may be used to refer to smaller streams, as may creek, run, fork, etc.
A River starts at a point called its source, and enters a sea or lake at its Mouth. Along its length it may be joined by smaller rivers called tributaries; A river and its tributaries are contained within a drainage basin called the watershed. The point at which two or more rivers join, is called the Confluence.
To receive credit for this Earthcache, you must complete the following 2 requirements.
1) Upload a picture of your face, your GPS, at the posted coordinates.
2a) Determine the flow rate in "Feet Per Second" for EACH of the two rivers
This may be done by measuring & marking a distance along each of the different Rivers banks, then tossing in a leaf upriver from your starting point. With a stop watch, time how long it takes your leaf to complete your measured distance course. Then calculate that into "Feet Per Second" for EACH River.
2b) Measure the width of each river as they meet. This can be done by using your GPSr to mark coordinates on each side of both rivers
