Mayank Bajpai 0 Posted December 11, 2019 Report Share Posted December 11, 2019 Hello, Can anyone please tell me that how velocity is calculated from flow data in GMS(not through GUI). Though I had already referred to the following the link: https://www.aquaveo.com/blog/2012/05/15/velocity-vectors ,the velocity calculated by me is not matching the velocity obtained through GMS. I had applied the following for the calculation of velocity: V = Q/(saturated_area*porosity); where, Q is the flow through a cell face, obtained from ccf file, Saturated area = (head-bottom_elevation)*cell_width {for unconfined aquifer} and head is obtained through .hed file. Thanks in advance. Have a great day! Quote Link to post Share on other sites
Lalith 0 Posted January 29, 2020 Report Share Posted January 29, 2020 Please try removing the porosity from your equation. Probably, the model calculates the Darcys Velocity , which is simply equals to Q / saturated_area. Quote Link to post Share on other sites
