Abstract
Main hydraulic control structures are the major structures that’
represent the means for flood control, and regulating flow and distribution
of water for agricultural, industrial, municipal purposes and others. They
are considered as a means for navigation and energy production as well. In:
some cases, as in Egypt, they represent a means for road facilities too. In
anyway they represent a vital value for human safety and country’s
economy.
To obtain continuous use and proper function of these structures, a
safety control programme should be implemented to detect any
deterioration or defect and apply the suitable corrective measure in early
stage. In Egypt, there is no formal regulations or codes for identification of
such programme. Also a problem appears when the available limited
resources jeopardise the inclusion of some corrective measures needed to
assure safety for some hydraulic structures.
The present study aims at proposing a safety programme for the
hydraulic structures to be established in Egypt, and developing a decision
making tool to be used, as a part of the safety program, in planning the
maintenance activities.
This study focused on reviewing the applied safety programmes in
well known international organisations, and the actual informal safety
activities applied in Egypt, with the input of actual practice and experience
of the experts. The main steps of the safety programme has been identified
and discussed with some details so that the programme could be initiated
for application in Egypt.
The decision mak.ing tool for planning the maintenance activities was
based on the integration of the risk assessment and the optimisation
concepts. It incorporates the estimation of possible economic risk that may be a consequence of the deterioration existence, estimation of the remedy
action cost, and the optimisation between the possible risks and the costs
and resources required to eliminate these risks. The tool output is the
definition of the optimum plan which achieves the maximum benefit from
the available resources, thus achieving the optimum safety of the structures.
The application of this tool implies enhanced risk and probability
estimation which depends, to a great extent on the use of experts. A
simplified method has been developed to eliminate a considerable amount
of preparatory work and limit the severity need to experts for risk
assessment, for the sake of making the method more practical. The
developed method depends on the use of two factors that should be
identified for the structure and the detected deterioration. This simplified
method has been found to be reasonably acceptable to be used as a decision
making tool.
