Geography-III-Ans
8a)
i)Encroachment : More migration lead to
less availability of land which lead to higher economic value of land. 
ii)Pollution: Explosive increase in the urban population without
corresponding expansion of civic facilities such as lack of adequate infrastructure for the disposal of waste results in waste clogging the
natural channels and storm water drains.
iii)Illegal mining activities: Illegal mining
for building material such as sand and quartzite both on the catchment and on the bed of the lake have extremely damaging impact on the water body. 
iv)Interference in drainage system:
Drainage congestion caused by badly
planned construction of bridges , roads , railway tracts, hampers the
flow of water and the result is flood.

8b)
1. Flooding leads to loss of human life 
2. Flooding leads to damage to property
3. It leads to destruction of crops
*5A*

*5B*
*i.* The length of the minor arc of a great circle is taken as the distance between two points on a surface of a sphere in Riemannian geometry where such great circles are called Riemannia circles. 
*ii.* These great circles are the geodesics of the sphere.
*Iiii* For most pairs of points on the surface of a sphere, there is a unique great circle through the two points.

ii)Flooding leads to damage to property
iii)It leads to destruction of crops
8c)
i)Improving Drainage Improving water drainage helps control floods by facilitating easy flow of excess water, especially in urban areas during flash floods.
ii)Building Dikes and Levees Dikes and levees are flood-control structures built to fight river flooding and water surges.
iii)Building Canals; Canals are artificial water channels that can be crucial to flood prevention. Canals facilitate control of water levels passing through, and form linear reservoirs and water locks.

iv)Harvesting Rain Water Harvesting rainwater involves collecting and storing rainwater and can not only prevent floods, it can also curb urban water scarcity.
