alsalam alekom all this is my answer(idea ) for problem 10 sheet 1 if i have any mistake plz anyone can tell me
what i mean is v(evp)=(40/1000)*(50*1000^2)=2*10^6
1st: v(runoff)=v(rainfall)*runoff coeff
v(run off)=v(in)
then: V(in)=(1850/1000)*(250*1000^2)*(0.45)=208.125*10^6
V(out)=v(evp)+v(withdrawn)
vout=2*10^6+vwithdrawn
deltastorage(s)=1-0.85
then v(in)-v(out)=ds
so u can get v(withdraw)

2nd about the answer of problem 9
i asked engineer haitham and he told me (use this law)
v(in)-v(out)=ds
but take in consideration that ds will be +ve if there is an increase and in case of drop it'll be -ve
so in this prob. we will take
6*10^6-v(out)= -0.5*500*10000
then v(out)=8.5*10^6
