It helps in planning. As in being unable to use a track in winter because it crosses a riverbed which only has water in it during winter. Or planning a hike where you take account of water sources to use in an emergency if there is a problem with your bottled supply. "Seasonal" isn't a guarantee of such things, of course, merely a guide to probabilities, and it says that those probabilities are far higher at certain times of year than at others. "Intermittent" is also a guide to probabilities but does not give a guide as to which times of year (or which years) are more likely than others, because such things cannot be determined, it says water might be there or might not. "Ephemeral" says that the might be water there but it's unlikely and if it is there is probably won';t be there for long. -- Paul
