[QUOTE="Hriston, post: 6905437, member: 6787503"] Yes, well the procedure as I've outlined it so far is to determine terrain type for the space being moved into as per the DMG, and then make a separate roll to determine the existence of a coastline, road, or major river which feature would lie across the path of the adventurers in roughly the middle of the space in question. Yes, once established as existing, the river is understood to extend in both directions, unless the party is currently following a river-course, in which case the newly encountered river is a tributary to the one being followed and extends upstream in the opposite direction to that which is indicated by its direction of flow. Direction of flow is determined with a 50% chance of each direction (right or left with reference to the adventurers' path) and indicates what is upstream and what is downstream. Downstream, the river extends (course determined randomly as given upthread) until terminating at the coast (or an interior drainage which is simply a coast line that turns back on itself), although the possibility of a river disappearing underground, perhaps into a cave system, is an interesting complication that it seems desirable to add in. Upstream, the river's course continues through all terrain types except mountains and perhaps hills, in which case it is considered to have its source in that space. Also, if the river's upstream course runs into a space containing a coastline, then it is considered to have its source in some high ground that lies between it and the sea itself. Yes, the underlying methodology calls for established features to override any results that would contradict them and re-rolls to be made. The shape of the coast is determined by the same random method that determines the course of rivers, i.e. roll d6. Results 1-2 indicate that the feature turns clockwise, 3-4 indicates that it continues straight ahead, and 5-6 indicates that it turns counter-clockwise, but any result that has the feature doubling back into a space where it has already been established not to exist must be re-rolled.
