Hey Bill, thanks. I get that, BUT the problem I have trouble understanding is that by my logic, the higher the number (i.e.: efective porosity) the FASTER you can drain the aquifer, right? But...when one inputs the number 0.05 (5%) in comparisson to 0.15 (15%) for Sy (open aquifer) in transient model you get that drainage is a lot faster with the 5%....drawdown is a lot faster in 5% that in 15%....and that i don't understand if it's correct. Thanks, m

Hi all, I cant find an explanation on what is the unit that is used in specific yield filed in GMS. Is it the percentage (0-1) or soemthing else. I find getting strange result as the water gets drained faster when Sy is 0.04 in comparisson to where Sy = 0.15. Does anyone has any idea regarding that?

Hi all, what would be the best way to simulate Ranny well? Well with horizontal MNW2 wells or series of well in circular pattern with proportional flow? Open to ideas? m
-
Hi, when i try imodelling horizontal well using MNW2 executable always craches. When checking the model, model checker gies no errors. Is there a way to check why the run crashes? thanks, m
-
Thanks GMS user...i'll check it out. m
-
Hi, no i mean i can't find the actual equations on which these paramateres are calculated in GMS...

Hi Sean, thanks fot the help. It works now. Do you have any idea how storage coefficient and specific yield is calculated in GMS? thanks, m
-
Hi Sean, thanks for explanation. Coudn't i simply use Cell rewetting? What do you mean by adjusting the elevation of layers? Thanks, m

I am sorry but i can't attach any file biger than 29 kb...

Hi all, i am having some problem with modeling dewatering of excavation pit. I created a simple 4 layer model (with flat borders between layers). Hk for eac layers are as follows, 1e-3 m/s, 1e-6 m/s, 5e-3 m/s and 5e-3 m/s. Layers 3 and 4 are the same i just divided them, so that i coul model the depth to which sheet wall is designed. I modelled dewatering with several (around 30) pumping wells. Here comes the problem. When setting pumping rate to -0.007 m^3/s(unit) i get really small drawdown. But if i set pumping rate just a little bit higher, like -0.008 (unit) i get all DRY CELLS in layer

Hi Todd, i' ve tried changeing the units. I get flowrate, but still there is no flowlines?! I've also sent the GPR file with this project to support@aquaveo.com. Hope you'll get this file... thank you matevz

Hi all, i have constructed a 2D model in GMS for calculation of SEEPAGE. I have a DAM in which water table on one side is at 171 m and on the other on 169.0 m. In dam there is a jet-grouting sheet which has a very low permitivitty. I have also 4 layers with such conductivity factor k (from top to bottom): 1) k.1 = 5 x E-5m/s, 2) k.2 = 1 x E-7m/s, 3) k.3 = 5 x E-5m/s 4) k.4 = 1 x E-9 m/s The situation is shown in the attached picture. When I run the model i get the result for total flowrate = 0.0000 m^3/s/m. Why? Also i do not get any flow lines? WhY? I have tried to figure this
