Uh, just so you know: a jungle and forest are the same thing, just different names. Anyway, here lets see...
- a river: needs some rainfall and drainage...Well, this is already covered by
- forest biome: at least 33 drainage and 66 rainfall (75 rainfall for broadleaf). Also, between 100 and 300 elevation - elevation control can be done simply by limiting map to 1 elevation and putting volcano(es) so there are some mountains still for dwarves.
- temperate temperature: giving the map a flat temp would be simplest way to accomplish this. Setting variances to 0 enables one to get what you want.
- multiple metals: high mineral frequency.
- flux stone: setting low volcanism in general would help.
- deep soil:
Huh, I do not know soil.
- clay: random soil type.
- no aquifier: high elevation and low drainage should work.
Sure enough, only thing that gives me trouble is deep soil initially. After a few tests, I find that low and medium gets only medium soil levels, while 100 drainage gets deep soil right away - while covering most of the map in aquifers as expected (rainfall is already high with 75 given for broadleaf forests)....Probably do not want to put that so high :p
Somehow, the rainfall poofed on some map...did I forgot to disable variance? *shrugs* Anyway, no aquifer and deep soil on both biomes.
