Document Summary
After a forest fire on a hillside the risk of mass wasting would be: increase. The difference between runoff and infiltration depends on. Sheet flow develops into tiny channels called rills. Gullies join to form brooks, creeks, or streams. Stream is any water flows in channel, regardless of size. A river carries substantial amount of water and has many tributaries. Imaginary line separating one line from another called divide. A stream drains an area of land called a drainage basin. Sometimes visible as high ridge in mountainous regions. A continental divide splits a continent into different drainage basins. Rivers drain much of the land area. Climate differences and human intervention influence the character of a river. River systems can be divided into three zones: sediment production, sediment transportation, sediment deposition. Located in the headwater region of river system. Sediment generated by: bedrock broken into smaller pieces, bank erosion, scouring of channel bed. Sediment transport: sediment is transported in trunk streams.
