WATER HARVESTING Rabi H. Mohtar Purdue University West Lafayette, Indiana, USASlide 2
Dryland Agriculture of South Tunisia Southeastern Tunisia get mean yearly precipitation under 200 mm. Rainfed cultivating is bolstered for the most part by the water gathering strategies. In the event that: rain < 250 mm water system is essential for yield creation Problem is portraying the current WHS and evaluate the effect of these frameworks on the provincial groupsSlide 3
Water Harvesting in the Dry Upland Areas of Lebanon Rainfall under 200 mm for each year Poor cultivating groups Alternate products, for example, fruits is being developed as a practical product yet it requires extra water Problem is repository siting to give supplemental water systemSlide 4
Water Harvesting Classification Water reaping procedures are ordered into: 1) spillover water gathering that makes utilization of overflow as it is gathered, wiping out the capacity prerequisite, as "jessour"; 2) floodwater collecting and spreading or spate water system with redirection barriers called "mgoud"; and 3) overflow water accumulation and capacity in supplies of variable capacities with respect to drinking, creature watering and water system purposes.Slide 5
Jessours in the Matmata moutains. A pressure driven unit made of three parts: the catchment range, the patio and the dyke. The jessours are utilized to bank the spillover from the mountain chain .Slide 6
Tabias recently introduced in the piemonts territories. The dyke (tabia, sed, katra) is a boundary bound to hinder the silt and spillover waters. Its body is made of earth outfitted with a focal as well as horizontal spillway and maybe a couple projections (ktef), guaranteeing the clearing of the abundance water. It has a trapezoidal shape (length: 15-50 m, width: 1-4 m, tallness: 2-5 m). The tabias are currently broadly utilized as a part of the piedmont zones where the organic product trees (fundamentally olive and almond) forests are picking up larges regions to the detriment of brushing grounds.Slide 7
Flood spreading developmentsSlide 8
Recharge well in mix with a little gabion check dam. little check dams or spreading structures for occupying spillover waters. Now and again, energize wells are utilized likewise in blend with gabion units for aquifer revive. Revive wellSlide 9
Terraces for afforestation in Matmata. developed on soak slants. They are framed of little holding dividers made of rocks to back off the stream of water and control disintegration.Slide 10
Feskia or Cisterns utilized for drinking and creature watering. a storage is a gap delved in the ground with a gypsum or solid covering to stay away from vertical and horizontal penetrationSlide 11
Gabion structures We recognize two gatherings: Gabion with revive well Gabion without energize wellSlide 12
Gabion with energize very much Based on the working of these structures, it is recommended to adjust the repository framework , which exists as of now in the model. Be that as it may, the parameters must be changed : RES_K (Hydraulic Conductivity of the supply base): Since the repository is implied for long haul stockpiling of water, RES_K is low (shifts between 0 mm/hr (Min) et 1 mm/hr (Max) ). Be that as it may, our structures have an inverse part, to upgrade the invasion of water into the dirt and the aquifers. In this way, the porousness must be to a great extent higher than 1 mm/hr.Slide 13
Changing as far as possible Monthly outpouring information (lachures, pompage… ): The information is exhibited as a table of two lines and 12 sections (Min and Max day by day surge information for the month)… . For the gabion, it is recommended to set up an immediate associations with the precipitation Resv = f(pluie). That is when there is adequate precipitation the supply will be full and the water ought to be penetrated as well as vanished inside few days (1 to 4 days).Slide 14
The quantity of gabion units to be embedded The Reservoir framework confines the number to one unit by sub bowl . Be that as it may and for our case, these units are typically introduced along the waterway beds with variable separating (least 200 m). = Multiplying the quantity of units Structures measurement The measurements are factors Use normal qualities .Slide 15

Gabion without revive well similar comments are to be thought about with just a single parameter: The water powered conductivity is much lower . For instance, the normal water powered conductivity at oued Hallouf gabion unit is 180 mm/hr .Slide 18
Digue en terre Jesr déversoirs (menfess) Jessours These structures are experienced in the mountains. They could be embedded as focuses (X,Y,"Z") (table dbf) The normal penetration rate of the jesser of Amrich is 120 mm/hr).Slide 19
Tabias The tabias are procedures experienced in piedmont and level zones. They are provided in two ways: 1. Coordinate block attempt of spillover 2. Surge spreadingSlide 20

Note: When the redirection barrier is made of earth it goes about as fusible; it separates when the surge is fierce to anticipate harms on the developed grounds. Tabias on Oued HalloufSlide 23
