3 point problem

Shows a graphical method for determining the hydraulic head gradient vector and the inferred horizontal groundwater flow direction using measurements of hydraulic head at 3 wells. A fourth well is used to determine the vertical component

thanks for this video, it's usually hard to find help with hydrology homework

[@rudrashishmajumdar4251]

thank you sir

[@oldwolfp]

Thx

How you calculate del L in this please write the calculation

[@andresprieto5365]

How did you calculate the hydraulic gradient angle without using the semi circle ruler?

[@lcmurd1]

Hi Andres, I used the See-Thru ruler protractor, which is shown at the beginning of the video. Measuring the angle is not shown in the video. Larry

how did you calculated del L= 210m?..please do reply....its really urgent

[@lcmurd1]

Varnica, Del L is the distance between the head contours measured using the bar scale given on the map. Be sure to measure the distance along a line perpendicular to the head contours. Larry
