You can Chanel it around a town so there is no flooding
If some place needs water then you can divert the water to the specific place
Also stopping it and creating a dam can offer the positive results of inexpensive energy, increased recreation opportunity and flood control
Hope this helps

Answer:
The mentioned parental types are c+m- and c-m+. Thus, the recombinants will be c+m+ and c-m-.  
Now, the given distance between c and m is 8 map units. Thus, the recombinant frequency is 8% or 0.08.  
The total recombinants from 1000 plaques will come out to be 80,  
Thus, the recombinants of each type will be 40.  
Total parental type will be 920, and therefore, each parental type count will be 460.  
Thus, expected c+m- = 460, expected c-m+ = 460, expected c+m+ = 40 and expected c-m- = 40.
