Hmm, the last cookbook topic featured quite a lot of parameter sets, but here I see nothing but specific sites. Time to change that!
This here is the parameter set I used for my last world, I first made it as an expiriment to get as many fancy waterfall as possible. It has a rather unusual size of 129x257, I found the full 257x257 too large and the 129x129 too small. Anyhow, a list of remarkabilities:
-Lots of rivers and waterfall indeed, majour rivers and 10 z-level + waterfalls are not uncommon.
-Its surrounded by ocean, but inland oceans are quite uncommon.
-Higher elevation variance for more mountainside sites and generaly more detailed geography.
-Slightly decreased the rainfall and drainage maximum to cause for less elf overpopulation, and more desserts and wastelands (I like those)
-Lots of volcanos, along with variance and weighting in volcanism adjusted to make volcanoes with flux nearby more common. Keep in mind that its still going to take some effort to find a decent volcano site.
-Caverns adjusted to be more spacious and less with scribbly little pillar everywhere. Water maximum was also turned down after I got tired of my underground being an ocean all the time.
