From Lakes & Streams to Glaciers!

     Competence refers to how big a particle the stream can carry whereas capacity refers to how much material a stream can carry. If a stream has a low competence it would have much smaller particles than compared to a stream with high competence, which could be carrying boulders!



When the waters reach bankful, bankful discharge occurs in which the water topples over and creates levees. Then the channel recedes and it creates cutoffs. The deeper point of the river tends to be around the cutbank. I'd like to point out that even though there are no valleys in the above picture, whenever you see a V-shaped valley, one can assume it was formed by rivers.




  Something I enjoyed learning about was longshore drift. This kind of wave drift causes waves to bend, refract as the water slows down, and change position in how it hits the beach. As the swash comes in, it crashes into the headlands, then it goes back out as backwash.                       



    

     Glaciers scour the land as they recede, leaving behind things like kettle or trough lakes. Kettles are the depressions, in which water can fill, left from stagnant ice. When you see huge boulders left over in the landscape, it is posible they could be glacial erratics. On a separate note, outwash plains form from the melting of the ice from the volcano rushing over the landscape. 



Throughout time, water has remained one of the most important things to humans. In the beginning, water determined where early civilizations settled and grew. Now water is affecting us through concepts like glacial ablation.
