dear users, currently i'm working on my master thesis. the aim is to reconstruct hydrogeologic parameters via sisim in gslib on a contaminated site. afterwards a simulation with feflow will be done. my input consists of 35 borehole profiles with a total amount of 1200 datapoints consisting of 4 indicators. these points are set 10 cm before and after a layer is changing and in the middle of each layer (more points if the interval between points will be over 1 m). i'm relatively new to geostatistics and i'm experiencing some problems doing the indicator variograms. currently i use sage2001 (http://www.isaaks.com). the output are 3 rotations, 3 azimuths and 3 dips for the anisotropy. i'm not exactly sure how to put these into the sisim routine in gslib. the azimuths are the angles 1-3 for each indicatorvariogram but the rotations? and dips? for the search ellipsoid, which are the ranges i need to enter - the biggest and smallest of all variogram ranges? another problem i got is that my simulation results matches my pdf input only by ~60 %. will these results get better with exacter variogram inputs?
thanks for any feedback and advices, daniel
