Hi, Thanks for answering. As an attachement there is a description of my model with a scenario with seepage face and a scenario with wells. You notice that pump rate is very different : 5900 m3/d with seepage face and 1370 m3/d with wells. I don't understand why extract with seepage face is so important in comparison with wells... Thanks in advance if you take time to watch.
Hi, I do a model for aquifer drawdown and I don't understand why the pumping rate is more important with wells than with seepage face. In fact seepage face permits to have the water level wanted on the site of excavation while wells are going to do a drawdown more important in the center of the excavation. For example if I want a drawdown of -2 meters, with seepage face a drawdown of -2 will be in the excavation while with the wells there will have a drawdown of -3 meters in the center of the excavation and -2 meters on the borders. So seepage face should extract less water than wells so I don't why it's the inverse in my simulations. Thank you in advance for your answers.
