Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Sir how meanders support the formation of flood plains through lateral erosion. 2. and sir how levee forms. kya yeh ridge hai jo river channel k along banti hai
sir how Meanders support the formation of flood plains through lateral erosion. When rivers flood the velocity of water slows. As the result of this the river's capacity to transport material is reduced and deposition occurs. This deposition leaves a layer of sediment across the whole floodplain. After a series of floods layers of sediment form along the flood plain. Larger material and the majority of deposition occurs next to the river channel. This is the result of increased friction (with the flood plain) causing the velocity of the river to slow and therefore rapidly reduce its ability to transport material. This leaves a ridge of higher material next to the river channel on both banks of the iver known dge dae fo depar as a levee. ian ic the process of eroded material being dropped. This happens when a river loses fiatian close to river

1.Floodplains are formed when a meander erodes sideways as it travels downstream. When a river breaks its banks, it leaves behind layers of alluvium (silt). These gradually build up to create the floor of the plain /Flood plain. 2.The natural movement of a body of water pushes sediment to the side, creating a natural levee. The banks form levees made of sediment, silt, and other materials pushed aside by the flowing water. Levees are usually parallel to the way the river flows, so levees can help direct the flow of the river. 3.yes it's like the ridge separating the river bank and landpart. figures below

what's your questions
![eduncle-logo-app]()
sir it means river heals itself naturally by making levee and then move on
![eduncle-logo-app]()
Healing and breaking is a gradual and continuous process and it always flows unless and until it meet the ocean i.e the base level of erosion.

Good question gurmeet
![eduncle-logo-app]()
ok i got sir....and thankyou sir. its only possible with your guidance.
![eduncle-logo-app]()
carry-on quickly cover the geomorphology part so many to cover next Have you covered petrology??
![eduncle-logo-app]()
aftr this stratigraphy and then maybe structure geology then mineralogy then petrology

Floodplains are formed when a meander erodes sideways as it travels downstream. When a river breaks its banks, it leaves behind layers of alluvium (silt). These gradually build up to create the floor of the plain. Floodplains generally contain unconsolidated sediments, often extending below the bed of the stream. These are accumulations of sand, gravel, loam, silt, and/or clay, and are often important aquifers, the water drawn from them being pre-filtered compared to the water in the river. Levees are the ridges situated on the bank of river channels. Levees are usually made of earth. The natural movement of a body of water pushes sediment to the side, creating a natural levee. The banks of a river are often slightly elevated from the river bed. The banks form levees made of sediment, silt, and other materials pushed aside by the flowing water.
and sir wht is alluvial deposits.2. and are alluvial and alluvium are same thing?
Alluvial deposit, Material deposited by rivers. It consists of silt, sand, clay, and gravel, as well as much organic matter. Alluvial deposits are usually most extensive in the lower part of a river's course, forming floodplains and deltas, but they may form at any point where the river overflows its banks or where the flow of a river is checked. Alluvial is the process and Alluvium is the sediments deposited by Alluvial processes.
