Floodwater spreading for spate irrigation and the artificial recharge of groundwater (ARG) is an indigenous base knowledge that has been practiced for millennia in different parts of Iran. the main objective of this initiative in the Gareh Bygone Plain is,Breaking the interfacing, vicious circles of poverty-ignorance-desertification on the one and, and drought-flood on the other. The politically expedient and economically disastrous sedentarization of nomads in the Gareh Bygone Plain, I. R. Iran, a sandy desert with the mean annual precipitation and pan evaporation of 243 and 3200-mm, respectively, had wreaked havoc on the environment. Application of inappropriate technologies, mainly moldboard plows and pumps, in an area facing recurrent droughts, had desertified a scrubland, and made refugees out of the once prosperous nomads. The artificial recharge of groundwater (ARG) has rehabilitated 1365-ha of the plain and increased the irrigated farm field area 8-fold to 1193-ha during the 1983-1987 period. The recharged water has provided 250 occupations for the owner-operators and 95 positions for the hired hands.
The average annual forage yield has increased 5-fold to 445kg/ha. Deposition of fine- grained sediments in the systems has converted a loamy sand into sandy loam-loam, suitable for growing small grains. This, the establishment of 89-ha of river red gum forest and erection of 30-km of windbreaks of eucalypts and acacias have stabilized the moving sands and ameliorated the climate. The stem- and fuel wood yield of river red gum at the age of 18 has been 4701 and 813 kg/ha/yr, respectively. The above ground carbon sequestration of the same trees has been 2221 kg/ha/yr; therefore, our trees annually filter 220 tons of carbon out of the atmosphere.
The flooding caused damages and fatalities have been materially eliminated. Disregarding the intangible benefits, and assuming the beneficial life of the systems to be 20 years, the benefit: cost ratio for this project has been 22:1.Capacity building is achieved through holding seminars and field trips for students, professors, teachers, technicians, and policy makers, and publishing in scientific journals.For implementation of flood water spreading system in Gareh Bygone Plain,
We have designed and field tested stilling basins that convey relatively large flows (1-30 m3s-1) and convert them into a thin sheet of water, which spreads evenly over the first sedimentation basin without causing erosion. This has |

We consider this practice base on long-term impact indicators as follows:
Social impact
-The nearby towns and cities have been relieved of many of their social ills. Some of the arm and drug dealers have resumed farming. School attendance has dramatically increased. The ARG activities have put the GBP on the map. A 30-km paved road now connects the villages to the main highway. Electricity and telephone have been brought to the GBP.
Economic impact
-Hunger and poverty has been alleviated. As the number of bountiful wells has increased 10 fold to 130, the irrigated area has grown from 147-ha to 1193-ha. This has provided income for 250 operators and 95 hired hands. On average, each 4-ha of the ARG system creates one job opportunity. The price of farm fields increased over 1000 times in the first 5 years.

The forced sedentarization of transhumant pastoralists in the 1930s in the Gareh Bygone Plain (GBP), with a fragile arid ecosystem, initiated a desertification process that produced upwards of 500 environmental refugees. Overgrazing, fuelwood collection, senseless hunting, and the worst of all, the application of inappropriate technologies, moldboard plows and pumps, devastated this 6000-ha scrubland that teemed with wildlife. Watertable receded 10-m in 12 years, very close to the bedrock. Saltwater intrusion into the aquifer compounded the water shortage problem. Soil salinization was the outcome of irrigation with saline waters.
En masse city-ward migration of the inhabitants of 4 villages had left the GBP to a few hardy souls who eked out a living from 16 wells, which could be operated from one to 20 hours per day. The remaining women and children had to walk up to 6-km a day to fetch water, resulting in back pain and miscarriages for women and lower school attendance for children.|

the technology have been designed and field tested stilling basins that convey relatively large flows (1-30 m3s-1) and convert them into a thin sheet of water, which spreads evenly over the first sedimentation basin without causing erosion. This has been achieved by constructing long channels (270-7300 m) with a constant cross-sectional area and a gradient of 0.003 for 85% of their length, which is gradually reduced to 0.000 in the next 5% of the length; the final 10% is level.
-We have developed an economical technique for construction of a gabion diversion weir, which costs<1% of a reinforced concrete weir of the same capacity.
The application of innovative technology
Planting Eucalyptus camaldulensis in the ARG systems solved Clogging of the vadose zone of the ARG systems by floodwater problem. Preferential flow of water towards the watertable is now facilitated through the channels formed by the decomposition of roots, reaching a depth of 28-m.
-The presence of geologic nitrate in the floodwater was disturbing, since NO3 is supposedly carcinogenic. Fortunately, we have discovered that Eucalyptus camaldulensis is a bioremediator of this pollutant. NO3 concentration in our groundwater is <5 mg L-1. Moreover, we have found that the floodwater furnishes the needed nitrate fertilizer for the spate-irrigated wheat and barley.
Deposition of the suspended load in the ARG system dramatically decreases the infiltration rate. Therefore, an environmentally friendly way to puncture the crust had to be found. Fortunately, Nature has come to our help. We discovered that a sowbug (Hemilepistus shirazi Schutz) drills holes 7-mm in diameter and up to 180-cm in depth around quail bush . We planted this prized forage in the ARG system and the sowbug invaded the site

Eucalypts plantation as one of the project activities in the Gareh Bygone Plain(GBP) offers a potential plant material for ameliorating the environment through carbon sequestration.
A very high rate of survival and a considerable rate of growth of Eucalyptus camaldulensis made this species the tree of choice for CO2 sequestration. Survival rate of this tree at the age of eight has been 86%.  The annual increment of the same has been 7.76-m3ha-1. Assume that these two values are valid for a 10-year coppice rotation (Kowsar et al., 1996). Further assume that 70% of the yield is stemwood.  Therefore, approximately 50 tons of CO2 are taken out of circulation by the wood industry, and semi-permanently removed from the atmospheric pool from each ha every 10 years. |
As water is the most limiting factor in arid and semi-arid agriculture, and just one watering at the right time dictates the difference between success and failure, it is logical to start with the adaptation trials of the available stock in the FWS systems.|
Aggradation of environmental quality, an inevitable outcome of FWS in the deserts, provides a new medium for the invasion of adaptable macro- and micro- species. Appearance of truffle (Terfezia ssp.), three years after the installation of the FWS systems in the Gareh Bygone Plain in southern Iran, heralded a good turn in the life of a desert. Invasion of a sowbug (Hemilepistus shirazi Schuttz), 10 years after the start of FWS in the GBP, was the glad tidings for the designers and builders of the systems. This isopod, which forages on the leaves of Atriplex lentiformis (Torr.) Wats., a C4 plant, burrows deep into the sediment and facilitates infiltration into the very thick crusts .There has been a 5-fold increase in infiltration rate (IR) of the sedimentation basins following the sowbug appearance.  We find it advantageous to plant this forage species and propagate sowbugs to keep an almost constant IR in the FWS systems|

Iran is blessed with 43 mha of debris cones, alluvial fans and colluvial soils suitable for the water harvestig methods and artificial recharge of groundwater. Assuming that the average thickness and specific yield of these potential aquifers are 100m and 10%, respectively, they may store 4300 km3 of water, 10 times the mean yearly total precipitation of Iran. The entire volume of the reservoirs built in Iran in the modern times is less than 30 km3. The average cost of 1m3 of space behind large dams is $0.20 at the current official exchange rate. Therefore, the present value of the space in the aquifers, if utilized for water storage, is 860 billion dollars. The total cost of the ARG system construction on this 43 mha is approximately 3.5 billion dollars. Considering that the benefit: cost ratio of an ARG project implemented at the Gareh Bygone Plain in southern Iran was 20 (Bakhtiar et al. 1997), the real financial rewards of aquifer management come into focus. the losses of life and property due to floodings, the enhancement of environmental quality, such as carbon sequestration, and other intangible benefits were not included in arriving at the B:C ration of 20.

Achievement of 2 of the 8 Millennium Development Goals to 2015, Eradicate extreme poverty and hunger, Ensure environmental sustainability, may be facilitated through the application of the ARG techniques in a framework of an integrated approach|Flood, for the desert-dwellers, is a blessing in disguise, not a proverbial curse! Reclamation of eroded lands, conservation of biodiversity, provision of food, forage, and fuelwood and building materials, creation of employment opportunities, eradication of hunger, alleviation of poverty, reduction of flooding hazards and creation of a green environment are adjunct benefits of floodwater harnessing for the ARG.
|Establishing a close rapport with the nomads and transhumants in need of help is essential for success. They are suspicious of outsiders. As the women perform most of the backbreaking works, any activity on their behalf is an infringement of the male authority--and that causes grave consequences! We have persuaded their city-educated children to communicate our ideas to their elders.

-Coarse-grained alluvium provides the best reservoirs in deserts; it can store astronomical volumes of good quality water for millennia. Considering all the costs incurred in large dam construction, the cost of providing one unit of water through the ARG is 5-20% of that provided by such structures; location, depth to the water table, electricity and fuel cost are the determinants of this range|

"Water shortage" in the land of Iran, as in many other places, is an excuse of the timid souls who let the floodwaters go to waste while looking desperate.
|We have an astronomic wealth in the form of 30,000 dry qanats, which supplied about 300-m3 s-1before pumps lowered their water table below the drainage lines. Raising the water table to the pre-pump era will rejuvenate this environmentally friendly system, and save us the cost of pumping water.
