  One of the methods for water supplying and control of drying and flood is theapplication of water flooding. The work reported here was conducted at theexperimental station located in Tassuj plain, 110 km north-west of Tabriz in thenorthern of Oroumiye lake, situated between 45°18 to 45° 33E and 38° 15 to 38° 24 N,with an average annual precipitation of 362.3 mm, and average annual evaporation of989.5 mm. The study basin has an area of 5590 km2 with 3000 km2 on which floodspreading is possible. The aims of this research are investigation of efficacy of FloodSpreading Project (FSP) on vegetation cover and recharge of groudwater in Tassujstation. Remote sensing and GIS systems are effective and efficient techniques inwatershed management and investigation flood distribution in plains. After preparingmentioned parameters in GIS environment (using Arc GIS software), digital maps andtwo satellite images TM (1992) and ETM (2002, 2006) of the study area from floodspreading of Tassuj was used. Images were interpretated by Hybrid or optic method oncomputer monitor. The results were indicated that vegetation cover increased afterFlood Spreading Project equal 18% to 34% in 1378 to 1384 year. Bare soil decreasesin 9 years at last too. Deposit of drying, groundwater level does not decrease but alsodischarge of wells was increased. Study of unit hydrograph of Tassuj plain wasdeterminated that groundwater level decreases equal 10 meters in 1373 to 1380 butafter flood spreading in the1380 year it increased. Manuscript profile

  Spreading flood in GarehBygan-Fasa district has resulted significant improvement in ground water resources of the district. So, yearly water providing capacity of the district has increased from 4.08 to over 14.03 million m3. However, more than 26.9 million m3 is exploited now that is beyond of the capacity of the district’s water resources. The main objective of this study is the environmental evaluation of the Gareh Bygan project. Environmental value of the project is considered equal to the value of the water provided by the project. Water evaluation was also done in two parts, the over drawn water that is beyond the project capacity and the water that has been available after performing the project within the project capacity. Value of the overdrawn was estimated in two approaches. First the gross margin obtained from the over drown water and based on residual method was attributed to water and second demand for water was estimated. Based on the first approach, price of each m3 overdrawn water was estimated 460 Rials. The corresponding figure obtained from demand approach, was 399.6 Rials, while the price of water within the project capacity was estimated more than 2770 Rials. Based on the residual method total benefits obtained from over drown and within project capacity water was evaluated 5.93 and 27.57 billion Rials, respectively. It was also found that water price is highly dependent on the applied amount of water. Manuscript profile

  Most part of Iran is situated in arid and semi-arid areas. Among features are irregularity in precipitation and improper distribution in terms of time, flood and drought, soil erosion and desertification. Therefore, under such circumstances, the shortage of water along with its effect of farm lands has considerable effect on natural resources. Nowadays in most part of the world, in order to supply water, improve of soil fertility, prevent erosion and flood in additional to watershed artificial flood, flood spreading and aquifer management is utilized and its positive effects are always emphasized. In this study the effects of implemented flood spreading on some physical and chemical properties such as amount of organic mutter, Nitrogen, Phosphor, Potassium, clay, silt, sand, PH and EC comparing with the areas without flood spreading have been studied using T test. Results shows that amount of organic mutter, Nitrogen, Phosphor, Potassium and clay have been increased. The amount of silt, sand, PH and EC have been not changed. Results prove the positive effect of flood spreading on soil properties in this area. Therefore, maintain the implementations of such plans are emphasized. Manuscript profile

  Groundwater is the single water resource in many regions of Iran. This is considered to be a major limitation in the social and economic development of the country. Destructive floods and water shortage necessitate suitable strategies against flood control. Selecting suitable areas for artificial recharge and directing the floodwater into permeable formations are amongst the most effective strategies in flood spreading projects. Having combined GIS and MCDA approaches, the present study sought to locate the most suitable areas for artificial groundwater recharge operation in the Garabaygan Basin of Iran. To this end, the data layers relating to the eight effective factors were prepared in GIS environment. This stage was followed by elimination of the exclusionary areas for artificial recharge while determining the potentially suitable ones. Having closely examined the potentially suitable areas using the PROMETHEE II-SAW and Fuzzy-AHP methods, the land suitability map for artificial groundwater recharge was produced. The results of the study showed that most suitable areas for the artificial groundwater recharge are located in Quaternary Qg and Qgsc geologic units and in geomorphological units of pediment and Alluvial fans with slopes not exceeding 3 percent. Furthermore, significant correspondence between the produced map and the control areas, where the artificial groundwater recharge projects were successfully performed, provided further evidence for the acceptable efficiency of the integrated PROMETHEE II-SAW method in comparison with Fuzzy-AHP in locating suitable artificial recharge areas.
