Slide 2

Streams and Drainage It is vital that we make an audit of the hydrologic cycle. *97% of all water is seas (salt water) *2% of all water is in ice tops/polar ice *0.6% is groundwater (crisp) *0.2% is waterways and lakes (new) *0.16% is environmental water (new) Streams:  Gaining streams are those that take in water with time and have a tendency to augment. Losing streams are those that lose water with time and have a tendency to end up smaller. Discontinuous streams are those that are wet amid the wet season and dry in drier circumstances. There are a few seepage designs that create in light of shake sort: 1. Dendritic - stretching 2. Spiral - related with inspires/slopes 3. Rectangular - related with safe shake 4. Trellis - related with safe edges

Slide 6

There are a few phases of stream advancement: a. Early (pre-adult) - waterfalls and rapids display b. Center (grown-up) - broadening floodplains c. Develop - winding streams exhibit d. Maturity - exceptionally expansive, wide valley, Yazoo stream tributaries and oxbow lakes show *Materials conveyed by the stream is alluded to as bedload. *The bigger the particles, the less they are moved by water. Water has a tendency to round particles with time. Three (3) sorts of materials in streams: 1. Bedload/Traction Load - that which is overwhelming and pushed by the water 2. Saltation – skipping impact of grains Suspended load - that which is conveyed and ricocheted by the water 3. Broken up - really disintegrated in the water Head of stream is beginning stage; mouth of stream is "end".

Slide 7

Stages of Stream Development Initial Stage: Fast moving stream, contract valley Second Stage: Meanders create, broadening floodplain Last Stage: Wide floodplain, yazoo streams, and oxbow lakes create

Slide 11

*Channel shape depends on the speed of the stream and resistance of shake it is cutting into. *Water in streams tends to move speedier in the focal point of the stream and slower towards the outside . *Wider streams move slower than tight streams. *Outside of wander is known as a Cutbank and is related with disintegration . *Inside of wind is known as a Point Bar and is related with testimony . *Much (~45%) of the eastern bit of the U.S. is depleted by the Mississippi River, though the western part of the U.S. is prevalently depleted by the Colorado River. *The point between where seepage movements is known as a partition . *As water from a waterway (stream) exhausts into an extensive waterway like a sea, it frames a structure called a delta . *The Mississippi River discharging into the Gulf of Mexico is the sort case of a delta. *Deltaic exchanging happens when no greater silt can be added to a given range. Subsequently, the waterway takes the easiest course of action and moves or relocates.
