Document Summary
Major drainage basins in the united states: pacific western united states, atlantic east coast (east of the appalachians, gulf mississippi system (gulf of mexico) Precipitation interception (falling on plants) evaporation. Precipitation through fall (makes it to the surface) storage evaporation. Precipitation through fall (makes it to the surface) run-off fastest pathway to get to channels. Precipitation through fall (makes it to the surface) process infiltration storage, evaporation, or used by plant, through flow (2nd fastest), or groundwater. Sources: storms seasonal, melt water (snow released rapidly during spring) spring, groundwater persistent base flow, flow regimes perennial, intermittent, ephemeral. Flow regimes: intermittent: inputs in the winter, then stops & remain dry, perennial: flows all the time, ephemeral: river systems where water flows on a very irregular basis (desert) Sediment transport: erosion: picking up a part, translocation: moving the part somewhere else, deposition: putting it back down.
