In undeveloped and less developed countries of arid zones, the easiest way for water supply is withdrawal of groundwater. The negative perception of this method of water discharge is clear. Floodwater Spreading is one of the water resources management strategies in arid and semi-arid zones that has positive impacts on groundwater resources. The aim of this research is to demonstrate the impact of floodwater spreading on quantity of groundwater in Hashtbandi Plain, minab, Hormozgan province, Iran. Annual changes of water level were determined by reviewing water level of monthly data (2003-2014) of five observation wells. Though the floodwater spreading may not stop the aquifer drop, it has reduced the drop intensity of groundwater level. Results show that the least drop is in observation wells 25 that is near floodwater spreading. The results have shown that before implementing the water spreading project, fluctuation of groundwater levels were proportional to the utilization of groundwater resources, showing a declining rate. After implementing the project, a turning point on groundwater level was observed. However, in the years 2011-2012 due to drought and lack of water filling utilization plan and increased ground water usage, water level has decreased sharply.

Notes to investigate and identify problems in the implementation of research projects the effect of water spreading on water resources, the importance of methods, performance and results of research carried out previously necessary. Looking for station research, education and extension Floodwater spreading in the country, Monitoring and monitoring of various factors, including the monitoring of water resources is also on the agenda. In this paper, we investigate various sources of internal and external quantitative and qualitative parameters of water resources evaluated and is considered to reach the target. Investigation records show that during the past years in various parts of the country related research projects have been implemented or are under implementation. The results of this study indicate that the static level rise and increases in most stations control the water level in piezometer wells and aqueducts that our agriculture and increasing the flow. Plan spreading in many parts of the country and alleviate the effects of drought and sometimes neutralize it.
