WebStep 6: Draw a line that passes through and is perpendicular to each equipotential line. This line marks direction of flow. Step 7: Calculate the hydraulic gradient from the formula, i=dh/dl, where dh is the difference between the most upgradient and most downgradient equipotential lines and dl follows the direction of flow, which is not necessarily a straight … Webthe direction of groundwater flow, and equipotentials (lines of constant head), which show the distribution of potential energy. Flow nets are usually constructed through trial-and …

http://www.civil.uwaterloo.ca/maknight/courses/CIVE353/Lectures/week%204/Examples.pdf Web23 de ene. de 2011 · Beginner user of ARCGIS. Background info: Created equipotential flow lines using the contour function in ARCGIS. From here I am looking for a way to create groundwater flow paths based off of the created equipotential flow lines. These lines were created using my research data of hydraulic head values and elevation of the … WebIn the flow net there are 4-7 flow channels and 15 equipotential drops. The seepage is given by: q=kh 4-7 = x x = 3-1 x 10-5m3/s (per m) The pore water pressure is calculated at the points of intersection of the equipotentials with the base of the dam. The total head at each point is obtained from the flow net and the elevation head from the ... ridgid threading machine 1224
