Flood enhancement through flood control (Criss and Shock) 3rd feb

Question 1

Research showing…has led scientists to propose..

Answer 1

Research showing increased flood stages has led scientists to propose increased discharge within rivers is caused by anthropogenic activity (trying to stop floods etc)

Question 2

Although some scientists may say its due to….this report suggests…

Answer 2

Although some scientists may say its due t climate change causing floods, this report suggests building along rivers (channelization,levees etc) has caused increased flood frequencies.

Question 3

Criss and Shock evaluated…

Answer 3

Stage and discharge records for annual flood events to see if floods have increased due to anthropogenic force.

Question 4

Findings… no indication

Answer 4

No indication of increased discharge as a function of time, however flood stages have increased by 2-4m

Question 5

Criss and shock found…(measured how…)

Answer 5

Measured how different locations with different levels of management had changed and found that areas with more management (wing dams and levees especially) has increased flood stages.

Question 6

The data shows that.. (increased flood stages)

Answer 6

The data shows increased flood stages over 140 year period. One implication is rivers take a long time to react to changes in dynamics.
