| ABSTRACT: | The paper proposes an automatic algorithm for completing missing water level records of an observation well. The algorithm employs a simple additive model consisting of three components: a trend, which is an annual constant that may vary from year to year, a seasonal component which is a separate constant for each month, and a random component. The model is used to produce a sequence of synthetic water levels which has the same seasonal pattern as the actual observations, satisfies the condition of a small mean square error and forms the basis for interpolation between the actual observations. The method is computationally efficient. It was tested on a large sample of wells and gave satisfactory results. |
