Question
Follow the Ohio River downstream until it meets the Mississippi River. What town is found right before they meet? The distance from Tell City, Kentucky to where the Ohio River meets the Mississippi River is about 240 miles. Using the cursor, determine the change in elevation of the Ohio River channel over the approximate 240 miles stretch. (You can determine elevation at each location by putting your cursor over the river channel near these two localities and reading elevation off the bottom of the screen given in meters). What is the approximate gradient in feet per mile over this stretch of the Ohio River? Be sure to show work for partial credit.
Explanation / Answer
The town found right before the ohio and the Mississippi river meets is Cairo, Illinois
Elevation of Tell city, kentucky is 438 feet
Elevation of the meeting point of the two rivers is 292 feet
Change in elevation= 438-292= 146 feet
Gradient= 146 feet/ 240 miles= 0.608 feet/mile
