Question

How does urbanization enlarge stream channels?

How does urbanization affect wetland plant diversity

How does increased urbanization in a watershed contribute to a loss of riparian continuity?

How does urbanization increase peak discharge in a watershed?

Does increased urbanization lead to a decline in stream habitat quality? Why or why not?

How can increased urbanization lead to a diminished base flow?

Answer 1

A1)Urbanization blocks the natural flow of stream, so they are contracted in urban area but they leaves urban areas large amounts of water gushes out in a large velocity, so stream channel is widening

2)Due to solid, concrete structure, they couldn't flow in natural system so they find other areas to flow which enhances the stream channel.

B2)Urbanization leads to pumping of water to a large volume, so wet land loses it habitat immediately so that certain habtuate plants and animals could not grow due to lack of water.

Urbanization enhances dumping in wet land which hinder in infiltration and seepage

C)Due to large tunnel, bridge in the name of urbanization diversion channel usually constructed which destroys the natural continuity of riparian water shed.

Dam also constructed to generate electricity so that can be reason for a discontinuity in riparian watershed

D)Due to urbanization during high rainfall large amount of water blocked in a small area, when these water released ,they fish out in a large force which enhances peak discharge of water shed

E)Increased urbanization enhances the use of plastic wastage more power generation from coal and bio fossil when they dumped in a natural water habitat in degrade the quality of habitat

F)Base flow has been diminished large concrete structure vertically and horizontally for basement of buildings which reduce the horizontal permeability of stream,that us reason for diminished base flow
