DID MANUAL VOLUME 8
Foreword
The first edition of the Manual was published in 1960 and was actually based on the experiences and
knowledge of DID engineers in planning, design, construction, operations and maintenance of large
volume water management systems for irrigation, drainage, floods and river conservancy. The
manual became invaluable references for both practising as well as officers newly posted to an
unfamiliar engineering environment.
Over these years the role and experience of the DID has expanded beyond an agriculture-based
environment to cover urbanisation needs but the principle role of being the country’s leading expert
in large volume water management remains. The challenges are also wider covering issues of
environment and its sustainability. Recognising this, the Department decided that it is timely for the
DID Manual be reviewed and updated. Continuing the spirit of our predecessors, this Manual is not
only about the fundamentals of related engineering knowledge but also based on the concept of
sharing experience and knowledge of practising engineers. This new version now includes the latest
standards and practices, technologies, best engineering practices that are applicable and useful for
the country.
This Manual consists of eleven separate volumes covering Flood Management; River Management;
Coastal Management; Hydrology and Water Resources; Irrigation and Agricultural Drainage;
Geotechnical, Site Investigation and Engineering Survey; Engineering Modelling; Mechanical and
Electrical Services; Dam Safety, Inspections and Monitoring; Contract Administration; and
Construction Management. Within each Volume is a wide range of related topics including topics on
future concerns that should put on record our care for the future generations.
This DID Manual is developed through contributions from nearly 200 professionals from the
Government as well as private sectors who are very experienced and experts in their respective
fields. It has not been an easy exercise and the success in publishing this is the results of hard work
and tenacity of all those involved. The Manual has been written to serve as a source of information
and to provide guidance and reference pertaining to the latest information, knowledge and best
practices for DID engineers and personnel. The Manual would enable new DID engineers and
personnel to have a jump-start in carrying out their duties. This is one of the many initiatives
undertaken by DID to improve its delivery system and to achieve the mission of the Department in
providing an efficient and effective service. This Manual will also be useful reference for non-DID
Engineers, other non-engineering professionals, Contractors, Consultants, the Academia, Developers
and students involved and interested in water-related development and management. Just as it was
before, this DID Manual is, in a way, a record of the history of engineering knowledge and
development in the water and water resources engineering applications in Malaysia.
There are just too many to name and congratulate individually, all those involved in preparing this
Manual. Most of them are my fellow professionals and well-respected within the profession. I wish
to record my sincere thanks and appreciation to all of them and I am confident that their
contributions will be truly appreciated by the readers for many years to come.
