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 |
