| Abstract | ||
| Transmissivity (T) is one of the most important parameters in groundwater studies, it is generally estimated from pumping tests. (T) can also be deduced from abundantly available specific-capacity (Sc) data by using empirical approaches, In this study the relation between transmissivity and specific capacity has been derived using a data set of fifty six deep wells which penetrate Injana sandstone aquifer, these wells distributed in Rabia and Debagah -Mukkumar- Basins in Ninewa governorate. Linear and logarithmic simple regression functions have been performed and it is found that the logarithmic relationship to predict the transmissivity from specific capacity data has a better correlation (r = 0.90) than linear one (r =0.85). This is logically true because both transmissivity and specific capacity are lognormally distributed, it is possibility of using the specific capacities of wells in other parts of the basins to predict the transmissivity in these areas if the wells digging within injana aquifer and under the same hydrogeological conditions. | ||
