Channelization also caused native fish, birds, and mammals to disappear or stay away from the middle and lower river banks. The test to see if channelization worked came in the form of El Niño of 1969. Just before the projects were complete in 1970, the Los Angeles River basin witnessed nine days of nonstop rain. The mouth of the River at Long Beach recorded 102,000 cubic feet per second in spite of flood regulation.

Green in contrast to the blue of the sky.” Water, sky and earth are integral parts of this remarkable, profound novel about the complex emotional adaptation to the ramifications of a
ESS IA PLANNING Introduction Water hyacinth (Eichhornia crassipes), is an aquatic plant native to Amazon Basin. Water hyacinth can rise above the surface of the water as much as 1 metre in height. Seeds of this plant can remain viable for more than 28 years. It infests rivers, dams, lakes and irrigation channels on every continent except Antarctica. I will check if light affects the rate of photosynthesis of the water hyacinth.
