ABSTARCT :
Dams must be permanently maintained in a proper way because of extremely grave consequences that may occur in case of a failure. Maintenance refers to monitoring the condition of a dam and its belonging facilities, that is to identification and undertaking of all necessary measures for ensuring safety and functionality of the facilities in a timely manner. Maintenance involves various factors concerning the facilities as structures: natural factors, environmental factors and human activities. With such complex issues, the question of optimality and use of available resources arises. This paper presents an information system for the support of implementation of regulatory frameworks for the safety of dams, which serves to improve the maintenance system, safety and functionality of the existing dams and provide the protection of local communities. An integrated approach to all aspects of dam maintenance is essential for solving this issue. The development of the system involves comprehension of measurable indicators that are relevant for the decisionmaking process, modernization and extension of the system for monitoring relevant values and development of physically-based mathematical models with the aim of analysing and predicting of dam behaviour. The system is developed and implemented on Prvonek dam (a 90 m rockfill, water supply, latest facility of this kind that is constructed in Serbia). Some details on implementation and initial results are also presented.
EXISTING SYSTEM :
? This paper gives an outline for the development of an information system based on the existing systems with the utilization of some sensors and IoT.
? This paper presents an information system for the support of implementation of regulatory frameworks for the safety of dams, which serves to improve the maintenance system, safety and functionality of the existing dams and provide the protection of local communities.
? Dam maintenance and safety management in Serbia have recently come into general practice, based on existing legal framework for dam monitoring.
DISADVANTAGE :
? The main task is to verify if there exist some unexpected values in data, failure in measurement units or other problems.
? However, despite the fact that no serious incidents occurred, which would have jeopardized the safety and stability of dams, or lessen their usability, one must have in mind that, especially with ageing of dam constructions, emergence of various kinds of problems can be expected in future.
? Recognizing the importance of dams and reservoirs which belong to the category of facilities of special social interest, as well as importance and impact of their maintenance on the service life and functionality, and safety of the facilities, and having in mind the level of actualization of legislation.
PROPOSED SYSTEM :
• This paper also proposes a novel idea of collecting and sharing real-time information about water levels to an authorized central command center through far field communication.
• This system proposes the development of water level monitoring system by integrating the GSM module to alert the person-in-charge through Short Message Service (SMS) when the water has reached the critical level and it will automatically turn OFF the pump.
• Our proposed system removes these possibilities incorporating automated dam control system.
• A prototype of the proposed idea has been implemented using short range communication ( Bluetooth modules),Ultrasonic sensors and Arduino micro controller.
ADVANTAGE :
? An efficient system for dam safety management should manage not only information on safety-related activities, monitoring and analysis, but also their correlation and provide feedback information on all interactions when required.
? With the development of legal framework for dam maintenance and safety management, the presented information system will provide efficient tools for owners of dams for application of regulations.
? Web applications are also used for better communication with other interested parties.
? Information system for dam safety management is complex service-oriented system which allows the use of near real-time data in dam safety analysis.
