Considerations regarding infiltrations computation for an earth dam with a drainage prism. Case study: Manjesti Dam

Abstract

Lately, for dams of high and medium importance in Romania, made of local materials, it was introduced new measuring and control equipment which, in its great majority, achieves automatic data readings and interpretations. One such example is the automatic reading devices of the water level in the dam piezometric wells. The main issue of interest is the calibration of the infiltration curve through a homogeneous earth dam resulting from automatic readings, with an infiltration curve resulting according to theoretical calculation. This paper presents such a computation for a homogeneous dam made of local materials, provided with a drainage prism at the downstream slope base.
