Dam Safety During Design, Construction and Operation

Introduction In the foreword to the Malaysian Guidelines for Operation, Maintenance and Surveillance of Dams (Malaysian Inter-Departmental Committee on Dam Safety 1989), it is stated “The expanding inventory of dams has brought into focus the subject of dam safety”. At the time of the guideline publication, there had been a considerable increase in the inventory of dams with those constructed d...

Optimization of time and temperature of dam construction for thermal analysis of RCC dam

In RCC dams, usually large amounts of concrete are poured in a short time that the heat generated by the cement hydration has led to an increase in temperature in the dam body. In this research, Abacus software, which is a finite element software, has been used for thermal analysis of the dam during construction and concreting. This is how thermal changes are applied. For the structure of 50 c...

Environmental risk assessment of a dam during construction phase

The present study was conducted to assess the possible risks induced by construction of Gavi Dam in Ilam Province; western part of Iran, using MIKE-11 model and technique for order of preference by similarity to ideal solution. For this purpose, vulnerable zone of the dam site against the flooding risk of Gavi River was calculated for different return periods. The flooding zones were stimulated...

Tribal water rights: exploring dam construction in Indian country.

Feasibility study and construction of an underground dam in the Daryan watershed (Case Study Mashnaq Underground Dam)

    The water crisis in arid and semi-arid regions is a limiting factor for human activities and sustainable agricultural development. One of the new solutions in this field is the construction of underground dams. Underground dams compared to conventional dams that store river water in open reservoirs; block the subsurface flow of water in the cross-section of the river and store it under the ...

Monitoring of Cheragh-veis Dam During Construction Using Instrumentation Data and Investigation of dam behavior during impounding

One of the most important challenges in development projects beside designing and performing them is to control immunity and stability of the several parts during different stages of construction, impoundment, and operation.  The   main purpose of instrumentation in dams is to evaluate operation and reaction of these structures under different load conditions, developing a better understanding...
