Thousands of dams have been built around the world, but, the date of construction is
associated with a history of failures and collapse, due to the high water levels, generating
higher returns consequences disastrous for the environment and society
, when dam fails
released very large amounts of water threatened the lives of persons and property, it
returns to the short time available for warning and evacuation.
This paper provides an overview of the most important reasons for the collapse, with
a study about possibility failure product from supposed breach in 16 Tishreen dam, caused
by the flow of water over the top, where the predicted of breach that leading to collapse is
done and determine its characteristics, namely: High, width, time required to development
of the breach, the maximum flow out of it, and also generate flood maps that represent the
limits of the spread of flood wave downstream, in addition tosuggest a simplified plan for
the evacuation
Results led to the flooded wave caused by the collapsehurtling loaded
adischargeabout 54631 , causes a wall of water with 17 meters high moves
through the downstream river with 14 m/sec speed, the wave spreadover 45.24
,causing submerge for 7 villages the most important of it Stkhers and Rodo which are
completely submerged, and 30 economical facility the most important of it industrial area
that also completely submerged, the water depths ranged from 2 to 17 meter, which
causing heavy casualtiesand damage about 30000 people, and more than 7000peopleare
expected to die, unless the actual preparations of emergency plan.
This research study the cause failure earth dams After that it show the
more important problems which dams exposure.
During its construction and compassingthe importance causes of this
case and how we can processing it , and show also the necessar
y of
earth dams observerand the necessary reportsto showing that the work
of dam is good.
The research also discusses the analysis of earth dam using the Geo
slope program.
We have chosen many parameters as total stresses, vertical strain , and
pore water pressure to study change of this parameters with elevation
in the upstream , downstream , and core of dam and draw the requisite
graphsgraphs to compare this design values with reading of observer
devices to be sure of typical work of dam.
Finaly we showing the results and suggest many recommendations.
