Direction of flow from one step or decision to another. Roll over the buttons to find the river that correctly matches the contours. A contour line is a type of isoline; in this case, a line of equal elevation. 4) The marks are projected upward to located dots of a piece of lined paper. Rivers often flow a long way before crossing a countour line, which would be the gold standard, but one can make a reasonable guess at flow direction by examining the shapes of islands and the pattern of bank cutting - the steepest cuts (closest packing of counter lines) will tend to be (overall, generally) where the current hits the bank most directly, toward the upstream end of the outside . What are Hachure Lines? What are Index Contours ? A large body of water is generally the source of water for a river. (2) Contour lines do not cross.

What are the 5 Rules of contour lines? 16) Figure 2. " Because we know that ground water flows from areas of high water table elevation to areas of lower water table elevation, we can infer that the general direction of ground water flow in this area is . The bend in the V points toward the higher end of the valley; this V points upstream, or in the direction from which the water flows, if there is a stream. 3) label each mark with the proper elevation. The area of the map above boxed in orange shows an area that has a fairly steep slope, while … Where are contour lines close together on a map? Rule 4 - every 5th contour line is darker in color. More widely- spaced contour lines indicate gradual slopes. The isovorticity lines in Figure 8.60 appear to be pushed downstream by the flow.

A contour interval is the vertical distance or difference in elevation between contour lines. 5) The dots are connected with a smooth curved line. 6. The bending of the contour lines near the river always points uphill, which means RIVERS ALWAYS FLOW IN THE OPPOSITE DIRECTION FROM THE WAY THE CONTOUR LINES BEND. If you walk along a contour line you will not go uphill or downhill. The "V" shape contours indicate streams and drainage. Rivers often flow a long way before crossing a countour line, which would be the gold standard, but one can make a reasonable guess at flow direction by examining the shapes of islands and the pattern of bank cutting - the steepest cuts (closest packing of counter lines) will tend to be (overall, generally) where the current hits the bank most directly, toward the upstream end of the outside .

Roll over the buttons to find the river that correctly matches the contours. 8. The arrow below points to the . 2. Cfs readings are taken at select points along rivers, and readings vary with location. Contour lines that are further apart indicates a slope that is relatively flat. 18 When contour lines are separated from each other . The bending of the contour lines near the river always points uphill, which means RIVERS ALWAYS FLOW IN THE OPPOSITE DIRECTION FROM THE WAY THE CONTOUR LINES BEND. 17 How do contour lines indicate streamflow on a topographic map? Show that uniform potential flow past an obstacle is an irrotational flow. Index lines are the thickest contour lines and are usually labeled with a number at one point along the line. What do the V-shaped contour pointing downhill indicate? B) Rivers always flow toward large bodies of water. Be notified when an answer is posted. 3 . Answer: You can find them on a contour map. A contour line that bends to form a V shape indicates a valley. As a general rule, water flows downhill perpendicular to contour lines.

They tell you when and where to meet your guide and you turn up but they don't and you've lost your money. What do contour lines on a topographic map show quizlet? When a contour line crosses a river or stream, they make a "V" shape and points to the direction the river is flowing. What direction do contour lines bend along a river: upstream or downstream? How do you identify the direction of flow of a river? water flows downhill, from areas of high elevation towards areas of lower elevation. also you can look up contours in the phone book, there is one where you can book the tour and pay for it over the phone. Image Source. The "V' shape always points upstream so the direction of stream flow is the opposite way. Using the compass point (relative direction of movement) notation, in which direction does the the . Rule 1 - every point of a contour line has the same elevation. Index contours are bold or thicker lines that appear at every fifth contour line. 5. The mathematical formula is: river width x depth x speed (flow and gradient) = cfs. The V points toward the area of higher elevation. What do Hachure Lines indicate? Contour line definition, a line joining points of equal elevation on a . A brief introduction to how to use contour lines on a topographic map to determine the direction a stream or river is flowing. What direction do contour lines bend along a river? How quickly would water in a river flow past far apart contour lines? The bending of the contour lines near the river always points uphill, which means RIVERS ALWAYS FLOW IN THE OPPOSITE DIRECTION FROM THE WAY THE CONTOUR LINES BEND. Hint: Far upstream of the obstacle, the flow is irrotational. Click on the buttons to check your answer. 2. Find one end of the river - trace the river until it either flows into a lake or sea, or until it peters out. This map can be used as a practice a. quickly would water in a river flow past very close contour lines . The contour lines you have drawn are called equipotential lines and show the general location of the water table. 8. When contour lines cros£ a river o stream they bend pointing uphill. The "Rule of Vs" - on a contour map, contour lines that cross a river will bend into a V shape, with the V pointing upstream (the opposite of confluence angles). Can contour lines touch? Isolines NEVER touch or cross each other. Rule 2 - contour lines separate uphill from downhill. A contour line is a line drawn on a topographic map to indicate ground elevation or depression. 2) make a mark wherever a contour line crosses the paper. Look at the Mill River in the map to the right. Describe what is happening in the flow that results in this effect. Intermediate lines are the thinner, more common, lines between the index lines. What is the elevation of the highest contour line on the map? 6. 4 cm Scale of map 1cm to 2km Calculate. All water flows downhill, from areas of high elevation towards areas of lower elevation. In reality, there is only a single, net, integrated force caused by the pressure variations along a body. A contour interval is the vertical distance or difference in elevation between contour lines. Determine the direction of the slope (aspect) from the index contour line to your location by drawing an arrow from the index contour line to the next higher elevation contour line. 4. 1) Lay the edge of a pice of paper across a line. A) Rivers shown on maps generally flow southward. The "V" points upstream or the river flows out of the mouth (wide part) of the "V". What are Hachure Lines? Subsurface topographic map also not used for the determination of the direction of the flow. Rule 4 - every 5th contour line is darker in color. 5) The dots are connected with a smooth curved line. For vertical cliffs, the lines will actually converge and over lap as one thick line.Gentle slopes - slow rises in elevation over a long horizontal distance are represented by widely-spaced contour lines. Index contours are bold or thicker lines that appear at every fifth contour line. Look at the Mill River in the map to the right. 10. How do contour lines indicate the direction a stream is flowing on a contour map? The bend in the V points toward the higher end of the valley; this V points upstream, or in the direction from which the water flows, i f there is a stream. Rule 2 - contour lines separate uphill from downhill. Contour lines never cross on a topographic map because each line represents the same elevation level of the land.
