Groundwater modeling for estimation of the recharge rate and identification of appropriate recharge sites in Damghan Plain, Iran
نویسندگان
چکیده مقاله:
Water is the main option of any development, so having an accurate management of groundwater is necessary. This study has been done in Damghan sedimentary plain in Iran, which is located in northwest of Semnan Province. The main objective of this research was to estimate the rate and right site of recharge in Damghan plain to prevent the aquifer from decreasing the water table. For this purpose, the monthly data of observation wells in a water year from September 2009 to August 2010 were prepared. Next, the type of aquifer, horizontal hydraulic conductivity (K), and the height of top and bottom layers were provided. Finally, the aquifer has been simulated by MODFLOW in two states: steady and transient. After simulation by application of different recharge rates, such as 11, 21 and 31 million cubic meter (MCM), it became clear that the fluctuation of water table on the southwest of the plain is less than the other areas, so it is considered as the right site of recharge. Meanwhile, the water table showed no significant change as a matter of recharge 11 and 31 MCM rates, but it displayed a considerable enhancement by adding 21 MCM recharge rate. Therefore, the study revealed that the appropriate rate of recharge is 21 MCM.

متن کاملEstimation of Groundwater Recharge Using Tracers and Numerical Modeling in the North China Plain
Water resource shortage has been a serious problem since the 1980s in the North China Plain (NCP), resulting in plenty of environmental problems. Estimating the groundwater recharge rate accurately is vital for managing groundwater effectively. This study applied several methods, including chloride mass-balance, tracers (bromide and tritium) and numerical modeling (Hydrus-1D), to estimate groun...
متن کاملGlobal-scale modeling of groundwater recharge
Long-term average groundwater recharge, which is equivalent to renewable groundwater resources, is the major limiting factor for the sustainable use of groundwater. Compared to surface water resources, groundwater resources are more protected from pollution, and their use is less restricted by seasonal and inter-annual flow variations. To support water management in a globalized world, it is ne...

In recent decades, the ever-increasing population, human needs, and changes in the consumption patterns of societies require the planning and management of water resources more than ever. Among the management strategies of underground water resources, we can point out the compensation of these resources through artificial nutrition and exploitation according to the capacity of aquifers. The stu...
متن کاملEstimation of Groundwater Recovery by Recharge in the Agricultural Area
The Kumamoto area, Kyushu, Japan has 1,041km in area and about 1milion in population. This area is a greatest area in Japan which depends on groundwater for all of drinking water. Quantity of this local groundwater use is about 200MCM during the year. It is understood that the main recharging area of groundwater exist in the rice field zone which have high infiltrate height ahead of 100mm/ day ...
