I'm a geotechnical eng. working on neural networks applications in to geo. eng.. I've designed a software able to predict some soil properties knowing some others.It works successfully but much more data records are needed to predict the propeties of a wider range of soils.I'll be very thankfull if you send me some data or introduce a proper database. A very good database may consist of records containing, porosity (e),water content(w), plastic and liquid limits(LL , PL), strenght parameters(fi ,c) for UU,CU,CD conditions, coefficient of permeability (k),percent finer than #200 seive,% saturation, specific gravity of grains (Gs). All databases are welcomed even if it does not contain the all parameters.
Also,such databases but related to rock parameters are welcome.
I'll be happy to send you any other info about this.
I'm ready to send you the final completed software as soon as completing.
