Scientific methodology for compiling a dam passport during its life cycle based on engineering surveying and geodetic monitoring

Abstract

The public and property risks associated with dam failures are very high, due to the location of settlements in areas of potential flooding, as well as the construction of new dams in less than ideal areas (in far from ideal territories). Due to the variety of risks that threaten dam structures and their surroundings, it is necessary to identify the possible causes and consequences of dam failure, and then develop a program to improve its safety. The monitoring of dam behavior/performance needs to start from the first days of construction and continue throughout the life cycle. The conducted study suggests a scientific methodology for the preparation of annual dam passports, which should contain all the data and information obtained from the date of the dam's creation until the issuance of the passport. The study also makes recommendations on the types of data and information that should be included in the dam passport, which will enable workers and experts in the field of dam life cycle monitoring, as well as responsible persons, to take the necessary measures and proactively resolve any problems that exist or may occur.
