“…Therefore, tight water connection between irrigation area and non-irrigation area suggests that natural ecosystem needs to be considered in agricultural management in arid environment. Manghi et al (2009) estimated regional groundwater recharge using a hydrological balance method. In this method, ARCGIS 9.0 Geostatistical and Spatial Analyst applications were used for interpolating/extrapolating and creating grids for specific yield, bedrock elevation, and raw groundwater data.…”

Scarcity of water is now the biggest threat in many parts of the world, specially in arid and semi arid regions. Establishing balance between water resources and the demands in a catchment scale basis could be one of the most important strategies to overcome this problem. In this regard, determination and analysis of water balance components (inputs and outputs) would be necessary. This study has focused on estimation of water balance components in arid-mountainous catchment of Manshad in Yazd province of Iran, during the year 2006-2007 using remote sensing and GIS techniques. To estimate actual evapotranspiration (ET a ) of the catchment, time series of MODIS images were obtained and used via Surface Energy Balance Algorithm for Land (SEBAL) approach. Measured precipitation (P) and runoff (R) data of the catchment were also used to calculate water balance equation components. Results indicated that a large volume of catchment water (about 70%) is wasted through evapotranspiration, while the rainfall is not enough to compensate this volume of water during the year. It seems that the negative (descending) trend has become dominant to the water budget of the area and gradually moves to harsh conditions of water shortage in future decades. Therefore, some actions would be necessary to overcome the problem. Water conservation strategies‚ improvement of water use efficiency, and control on agricultural field expansions are some solutions that could be advised for the studied catchment.

“…The inflow water could be estimated by the specific yield and groundwater level from the beginning to the end of the experiment process. As it is mentioned in the research of Du in Shijiazhuang city [19], the volume of water that can be stored in groundwater reservoir is defined as the effective stored water, or effective storage capacity (ESC). The ratio of ESC to the volume of recharge water is defined as the effective storage rates (ESR).…”

Abstract:To improve the efficiency of utilizing water resources in arid areas, the mechanism of artificial recharge effecting on groundwater reservoir was analyzed in this research. Based on a generalized groundwater reservoir in a two-dimensional sand tank model, different scenarios of the infiltration basin location and recharge intensity are designed to study how to improve the efficiency of groundwater reservoir artificial recharge. The effective storage capacity and the effective storage rate are taken as the main parameters to analyze the relation between recharge water volume and storage capacity. By combining with groundwater flow system theory, FEFLOW (Finite Element subsurface FLOW system) is adopted to set up the groundwater numerical model. It is used to verify the experiment results and to make deep analysis on the rule of water table fluctuations and groundwater movement in the aquifer. Based on the model, different scenarios are designed to examine the combined effect of recharge intensity and intermittent periods. The research results show that: the distance between infiltration basin and pumping well should be shortened appropriately, but not too close; increasing recharge intensity helps to enlarge the effective storage capacity, but it can also reduce the effective storage rate, which goes against the purpose of effective utilization of water resources; and, the recharge intensity and recharge duration should be given full consideration by the actual requirements when we take the approach of intermittent recharge to make a reasonable choice.

“…While tracer techniques, numerical models, and hydrological budgets can be used in water balance management, the simple water balance, while the most basic of methods, can provide fairly acceptable results. Other approaches may prove to be complex, time-consuming, or draw on data requiring sophisticated acquisition methods, making them a less than optimal approach for managers and hydrologists in the field (Manghi et al, 2009). One of most widely employed yet simplest methods of evaluating the groundwater budget is the water balance equation (WBE).…”

Quantifying the Influence of Sinkholes on Water Balance in Iran’s Golgir Alluvial Plain

Abstract. Southwestern Iran's Golgir plain lies on chalky bedrock made up of Tertiary gypsum surrounded and covered by thin Quaternary deposits. Since the onset of the new millennium, this region and its farmland has been prone to land depression and other instability phenomena linked to gypsum dissolution. A simple water balance over the period of 2005 to 2012 was employed to assess the role of sinkholes in these phenomena. Geological and geophysical features as well as initial water balance calculations confirmed the presence of sinkholes and their influence in the study area. A significant discrepancy (2.55×10 6 m 3 ) was observed between annual estimates of water inputs and discharge from the region, likely attributable to errors in identifying and quantifying output components. A bedrock map derived from geophysical investigations and the geological characterization of the chalky bedrock showed that, in comparison to the local groundwater table, there was a roughly 40 m drawdown towards the location of sinkholes. Groundwater inflow towards the aquifer was revised so as to include an identified sinkhole output component in the water balance equation, resulting in a much greater accuracy in the annual water balance estimates. Estimated annual recharge volumes ranged from 4.39×10 6 to 7.15×10 6 m 3 , with a mean of 5.64×10 6 m 3 . The water balance equation was shown to constitute a simple, cost-effective, and reliable approach to the recognition and evaluation of sinkholes in areas under similar conditions.
