Riverine Adventures II - More Resources

I'm taking a break from developing Twilight: 2000 material, returning to more generic RPG topics and back to a returning interest of mine - rivers and waterways. I've come across a couple of interesting products due soon, a recent PDF resource and a couple of useful articles and an alternate map approach (maps here) that I think make for good resources for riverine / waterway adventures.
