| Abstract | ||
| The estimation of recharge to ground water is the important basics to improve the use of ground water with other available resources, and to save ground water resource from depletion, especially when using large quantity of ground water during a long time such as for agricultural purposes. Al-Wand River Basin in Iraq suffers from water shortage of its requirement of Blajo–Al-Wand Project, and to cover this shortage, the ground water plays a good role to overcome this problem. In this study, three methods were used to estimate the recharge and ground water storage for Al-Wand Basin, these methods are: Water Table Fluctuation (WTF), Water Balance of Climatic for Basin, and Water Table Balance for Basin. The results showed differences between the methods used to estimate recharging and ground storage for this basin. The approximated values between drawl water from production wells and water balance of climate for basin method make it better the other methods, which the difference percentage was large with drawls water. Also, classifying the methods by assumptions found make (WTF) better method, because it contains less assumptions compared to the other methods. | ||
