| The well yield per unit drawdown is known as ______. |
| A. discharge of a well B. specific capacity of a well C. storage coefficient of an artesian aquifer D. discharge coefficient of an artesian aquifer |
| Answer: OPTION B – specific capacity of a well |
| Explanation: The specific capacity of a well is defined as the rate of flow through the well per unit drawdown. Specific retention is the fraction of water held back in the aquifer. Specific yield is the actual volume of water that can be extracted by the force of gravity from a unit volume of aquifer material. Porosity is the sum of specific yield and specific retention. |
