Surface Water
| Term | Definition |
|---|---|
| watershed | holds water; area of land that contains a common set of streams and rivers that all drain into a single larger body of water |
| divide | operated one watershed from another |
| bed load | rolling and sliding in order to transport |
| suspended load | sediments suspended in order to transport; most common |
| dissolved laod | sediments dissolved and transported |
| Nile | world's largest river in terms of disharge |
| formula for disharge | width x depth x velocity |
| dendritic | branching streams |
| trellis | paralled |
| rectangular | rectangular |
| radial | diverge from center area |
| centripetal | towards the center of basin` |
| capacity | the amount of sediments a rive can carry; depends on discharge |
| competence | the size of sediment; depends of velocity |
| calculate graadient | vertical drop/ distance |
| erosion happens | outside of a meander; cut bank |
| deposition happens | inside o meander; point bar |
| alluvial fan | low gradient distribution channel; decrease velocity; deposits into sediments |
| delta | a deposit of clay, silt, and sand formed at the mouth of a river where the stream loses velocity and drops part of its sediment load into a continues flow of water |
| gradient | decreases |
| velocity | increases |
| channel roughness | decreases |
| discharge | increases |
| width and depth | increases |
