[QUOTE="Hriston, post: 6905157, member: 6787503"] For my purposes, "what counts" is "what's quantifiable". And that turned out to be the list of rivers from Wikipedia, which means, as @[I][B][U][URL="http://www.enworld.org/forum/member.php?u=4937"]Celebrim[/URL][/U][/B][/I] has pointed out, that a result of 1-4 indicates a major river, one of the world's 180 longest. This subset of rivers includes those in both wet and dry climates. I believe the details need to be left rather abstract for the system to be adaptable to various established situations. Including a table, for example, that gives results of dry river bed, varying widths of river, waterfalls, rapids, or even underground watercourses, might be interesting, but may also produce some nonsensical results. I'll have to think about it. I'm comfortable for now with the idea that we're talking about one of the world's major rivers, maybe as wide as a mile or more when it is encountered, which may or may not be dry as seems suitable. As for smaller rivers and streams, I'm planning on generating those on a smaller scale than the one mile or larger spaces of DMG, p 173. There's an article on page 7 of The Dragon #10, (Vol. 2, No. 4, October, 1977), that presents a system for generating a square encounter area about 1/13th of a square mile in area, assuming a scale of 10 yards per inch. It gives a probability of encountering a stream of 4% in clear, rough, and wooded terrain types, 5% in mountainous, and 10% in marshy. This seems like the simplest solution. Upon rolling the 'major river' result, roll immediately to determine the river's direction of flow, whether to the right or left as approached by the party. When determining the river's downstream course, it continues through all terrain types until reaching the ocean. When determining its course upstream, if the river continues into a space that contains the seacoast, it is assumed that the headwaters of the river are separated from the coast by some high ground, perhaps a row of bluffs or some low hills. If, on the other hand, the river's upstream course continues into a space containing hills or mountains, it is assumed that the river has its source in that space. [/QUOTE]
