Hello to everybody!! I am using T-PROGS to try to simulate a complicated geological situation within a context of outwash glacial deposit, with silt clay with intercalations of sand lenses. I have some boreholes with information but in some cases distance between wells for a valid correlation are too far (ca 500m) therefore i was advised to use T-PROGS which seems to be perfect for problems of horizontal correlation. main groundwater flow from N to south (Y+ to Y-), distance along the groundwater flow between wells is from 50m to 450m, but i am having some issues: 1- while deciding the lag distances (strike(x) Markov chain) i would like to know what could be useful to put as max lag distance?? because i have no way to see if the values i am using are valid or not, only until the end of the whole flow model of mod flow 2- in the same manner while putting the lag distance of Y (dip (y) Markov chain) can anyone shed some light here PLEASE 3- besides, while creating the grid and the successive T-PROGS for the unconfined aquifers i want to have different materials within the same layer is this possible with the HUF, to avoid dry cells. THANKS A LOT IN ADVANCE FOR YOUR COOPERATION AND REPLIES ALEXANDER
Hello, I am a brand new user of GMS and have an issue I would like to discuss. I am using TPROGS to generate subsurface stratigraphy for an area where the stratigraphy requires a geostatistical approach, sediments have very little continuity and have been reworked by glacial floods. I have imported my .txt file using the text import wizard, selected borehole data, and I get hundreds of errors that all read: Borehole has same X,Y coordinates as another borehole, or duplicate X,Y,Z point was encountered. Point will be ignored. I have 1989 lines on the text file that correspond to about 288 boreholes. The boreholes are close to eachother in some areas and I converted the legal description (Township, Range, 1/4sec, 1/4sec) to Lat, Long. I suppose with the coarseness of the locations several wells appear to be in virtually the same location. Is there a way to randomize somehow to avoid this? Or maybe a way to accept duplicates instead of ignore them? Thanks
