Flow net construction
WebSeveral assumptions underlie flow net construction: 1) Two dimensional flow. This implies no recharge or discharge perpendicular to the plan of the flow net. 2) Isotropic medium. Hydraulic properties (e.g. hydraulic conductivity) are independent of the direction of measurement. 3) Steady-state flow. At a point, velocity of flow does not vary in ... http://www.civil.uwaterloo.ca/maknight/courses/cive554650/lectures/EarthDams/Seepage%20in%20Earth%20Dams.pdf

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 ... WebFlow Net. Figure 6-3 shows an example of flow net construction. Use this procedure to estimate seepage quantity and distribution of pore water pressures in two-dimensional flow. Flow nets are applicable for the …
WebA flow net that does not fulfill this rule is the trial flow net in Fig. 4.4b; another that does fulfill it is the finished flow net in Figure 4.4~. ... 136 FLOW-NET CONSTRUCTION should be raised if the first guess is too low or lowered if the first guess is too high. This correction automatically forces the equipotential lines to be moved WebA flow net is a graphical solution to the equations of steady groundwater flow.
