Badush Dam is
believed to be the first dam in the world which is designed to protect from the
flood wave which could result from the collapse of another dam; in this case
Mosul Dam. Badush Dam construction was
started in 1988 but it was stopped two years later due to unexpected reasons.
From that time on many attempts were made to resume construction without
success. Its value was stressed in a multitude of studies and technical reports
amid conflict of opinions on how to do this.
The original design of the dam as a protection dam was intended to have
a large part of the reservoir empty to accommodate the volume of the expected
flood wave for only a few months during which time itís content are released in
a controlled and safe way to the downstream. The lower part of Badush Dam which
has a limited height continues before and after this event to act as a low head
power generation facility. Among the later studies on the dam, there were
suggestions to introduce changes to the design of the unfinished dam which covered
the foundation treatment and also asked for constructing a diaphragm in the
dam. A long controversy is still going on with many possibilities but with no
hope to reach a final solution soon. Any rational solution must consider both
Badush Dam and Mosul Dam together as the safety issue
involves both of them. This paper may be seen in six paragraphs. The first
three describe in brief the history, the outline design and foundation
treatment of the dam, therefore, setting the background to follow the conflicting
views over its purpose and future which is discussed in the following two
paragraphs. The final paragraph is devoted to discussion and our conclusions.
