    Abstract

    This technical note describes the installation and performance of eight vibrating wire crackmeters placed on the bed of Santos Morcillo Lake, Ruidera Lakes Natural Park, Central Spain. Waterproof crackmeters were used, and special attention was taken to anchor them to the bed of the lake. Data loggers were installed on upright posts above the lake water level, and continuous crack opening data were obtained. The data consistency is shown by the low deviation of the readings with respect to its trend, which, in turn, is well correlated with the overall hydrogeologic behavior of the system. The data indicates the correct performance of the measuring system. Therefore, at least for periods of up to 1 year (time window of the study presented here), waterproof crackmeters may be used with confidence in underwater conditions.
