Objectives Studying a deferent solutions to the flood problem. Select the best solution which serve public sector. Find the best investment for the flooded water. Enhance the agricultural sector of Marj Sanour. Proposed Solutions Water collection ponds Literature review Meteorological information Vesting site Literature review Water budget: Storage = Income – Outcome Design flood : Plotting position based on weibull method P = , T=1/P Where: p is probability of exceedance , m : rank , n : number of annual rain fall data. T is retain period Soil Weight volume relationships: Literature review 10 Evaporation pan test Literature review 11 Viseting site Meteorological Data Rainfall % Oct Nov Dec Jan Feb March April May 2.79 12.62 22.49 23.92 19.62 14.46 3.76 1 Month % Evaporation VS Rainfall evaporation Oct Nov Dec Jan Feb Mar Apr May Jun Jul Aug Sep 133.30000000000001 93 62 62 67.7 93 138 201.5 234 254.2 232.5 180 rainfall Oct Nov Dec Jan Feb Mar Apr May Jun Jul Aug Sep 18 72 139 149 122 87 27 6 0 0 0 0 Artificial Recharge 1104 m3/d 8033 m3/d Two injection wells were constructed by P.H.G Recharge test capacity was conducted Pumping Water to nearbay Wadi Wadi Massen I II III Selection Criteria Score Weight (%) A B C Economic 10 5 1 5 5 25 8 40 Social 60 30 8 240 6 180 2 60 Environmental 40 20 6 120 8 160 1 20 Political 10 5 8 40 5 25 1 5 Agricultural 80 40 9 360 6 240 1 40 Total 200 100   765 630   165 A: water collection pond, B: Artificial Recharge, C: Pumping Water to Wadi. Grades: (1-10) : 1 is bad and 10 is good . Multiple Criteria Decision Method Data Analysis Storage = Input - Output 20% probability of exceedance 5 years return period 700 17 Data Analysis Storage = Input - Output w% = 10 w% = 30 w% = 35 w% = 35 n= 0.45 n= 0.40 n= 0.40 %= 30 and n= 0.49 = 0.42 Available free water = (0.42- 0.3)*3= 0.36 We take it 350 mm So R = P – 350 = 700 – 350 = 350 mm where R: runoff, P: rainfall Data Analysis Storage = Input - Output 5 7 6 8 4 2 3 1 Data Analysis Storage = Input - Output Design of a typical pond Design of a typical pond Relative works Summary and conclusion Data have been collected about the study area that is Marj Sanour. These data have been analyzed in order to identify the problems related to the drainage problem. It was reported by Ministry of Agricultural that the ponds solution will be done in the next 2 years. An artificial recharge option was designed by PHG to solve the Marj problem by constructing a two test boreholes in 2013. The design involved geometric and filter system. A third alternative has been suggested at the end of this report which involves pumping the flood water out of the Marj. The cost analysis in this project was obtained from an engineer who have sufficient experience in the calculation and processing of quantities and prices. The two main software programs used in this project is CIVIL3D and Google Earth Pro.
