Topography The study of or the making of detailed maps for a particular area
The focus is on landforms and elevation (height)
May include human features
“topo” means “local” or “place”

Topography and Water
Land features determine the direction and flow rate at which water will flow
Direction = water moves downhill
Flow Rate (speed)› Gradual slope =
slow moving› Steep slope =
fast moving

Watershed Area where all the water drains to
A small watershed will feed into a larger watershed
› Example:› Tuscarawas River is a
watershed that feeds into the Ohio River watershed, which feeds into the Mississippi River watershed, which feeds into the Gulf of Mexico

Topographic Maps Use lines and symbols to turn our 3D world into a 2 dimensional drawing

Topographic Lines Contour Lines represent elevation (height above sea level)
Contour lines never cross each other and never touch
Elevation of a contour line is always the same

Topographic Lines Index Lines have the elevation above sea level on it

Topographic Lines Interval Lines are contour lines without the elevation

Topographic Lines Contour Interval the elevation difference between each contour line
What is the contour interval on this map?The interval on this map is 10.

Complete this topographic map.
Contour interval is 10 meters.
Fill in the circles with the appropriate number for each index line.
Hint: The index lines that have small dashes attached to them show a decline in elevation.
