GW Engineering EXAM II FALL PROBLEM #2 - 2010 NAME 30 points USE UNITS of FEET SEGONDS ANSWER THE QUESTION ON THE FOLLOWING PAGE, SHOW YOUR WORK USE UNITS Of FEET SECONDS An aquifer test was conducted and data are shown below. The fully penetrating observation well was 190 ft from the pumping well. lnitial saturated thickness of the aquifer was = 88 ft. The pumping rate was 36 GPM wtrictr is 0.078 ft3/sec. Tell me everything you can about the aquifer using these data. 1.E+82 1.E+03 1.E+04 1 1.E+08 .E+05 1.E{ time {sec) f=1 w(,t-lfrtu*-l | lq,r'* cl* 3=Q u{r > b..'zf += lo o s t f; Lv)o 63 d.,. 6.? \- 3of12 NAME GW Engineering EXAM II FALL 2010 r,4r ( pRovtDE cALcuLATloNs AND ANEWERS TO PROBLEM 2 HERE Ua:0.?f 'vVqir) 5-- qt+ I' 100 s = 0'?( { : [rtDbs UP USE UNITS of FEET SEG.NDS O. w t)\) 5=@ 'G'-- {ri I 4Tr t : SH.W Y'UR W.RK!!!! 0.01 K \ 9+/s"c - 411 1g* 7*w-1 g S l*n4w > 7.Gx\t"t 8xto6y' l{ ; -L= r' /rg)<r" 5 b s --*e> 88 u=r3 S s = v^&* {ru S.t = 6af\ < 9t r_,rt r;;l:lE'- 010$vJ -1L{-. ,r* f*lo--:A 6.25 H -.\,q,x\ o-6vz*to4 _ o,llbt 6.tz al16E'v)?- F:\!{t k.u3 U,1tt6b tSs- T"Yttr69+ 5 .l---.L- L Pc)5'-.\)\g.\\.rvr *r'e F,L Wiu,.)S=3[" ,":_ r\'\a-.\ c (. - t uu;or?f t = EOsBc up'$,2( t -- t.q rloos "<- \z T=- Zrlo-3 'r5 Rt. a zxld-tr 3 h t*lD-L sY R{ = o,l\ = [x\D-s ll r'( J 4of12
