Preparing Clay Core for Building a Dam

[niz]

Hi!
I have one question about dams
When building a dam with clay core you must prepare that core ( so the moisture would be optimal , geomechanical characteristics would be satisfied and that sort of things,don't have time to elaborate all)
I have heard on lectures that there are two ways to prepare the core , to reach the required moisture
1. First way is cone method ( knobby cone method or you say truncated cone method..English is not my mother tongue so i have bit problems translating these)
2. The other way is , as our prof. translated -> method of Rice Fields
Now, my problem is , that i can't find anywhere about this rice fields method and i don't have it explained in book.
does anyone recall something like this, maybe you call it different way on English (you probably do!) so i can then search the net to see what exactly that is

Thank you all in advance

Have you tried translating the name your proffessor given from your mother tounge to english using google translate? That may give you a better idea.

unfortunately there is no option there for my language (Bosnian) :(
i am hoping someone will know what i am talking about and give me the right word in English , usually when translating technical words they use word closest to the language and rarely the exact translation
