    Keeper of the Knowledge Mentality

    Soil Infiltration Rates

    I'm designing a dry well. Once upon a time I ran across a table that listed NRCS soil types and estimated infiltration rates. I believe it was for septic drainfield design but that doesn't matter at the moment. Does anyone have a link to such a table. I'm having trouble googling it.

    site modeler objects

    Has any one found any good applications using multiple objects in the same model while using site modeler? From what I understand the sw becomes irritable when two objects are close by. Our former guru would make one object and define everything in the model as its element. Has anyone...

    Forum usage

    This forum doesn't seem to get much usage from its 200 members. Has everyone got this software figured out or is it secret knowledge.
