The purpose of this study was to manage the risks of Paveh Rood Dam at constructional phase by integrating TOPSIS & RAM-D techniques. After investigating the environmental conditions of the study area and the technical specifications of the dam, the risks of the dam construction were listed in a questionnaire. After analyzing the given scores by Preliminary Hazard Analysis (PHA), Technique for ...

Today water supply issue in large cities seems to be a big problem. This becomes more important with population growth and urbanization extension. To cope with this problem lots of irrigation and drainage projects have been implemented and operated that subsequently many socio- economic and cultural effects have been brought to the areas . The objective of the present study is to survey the soc...

One of the methods for dealing with the problem of water shortage and the decline of groundwater levels in the arid areas is the construction of underground dams. It is difficult to make a decision about suitable locations for the construction of underground dams because of the necessity to consider numerous factors. Some of these criteria are hydrological, geological and geomorphologic charact...

Approach to risk management, knowing the potential risks in realizing construction of dam on side work owner East Java area. In constructing a dam, job can affect project's success. A practical management approach is carried out achieve schedule, cost, quality, and service. This research aims identify provide priority order for project that are most likely occur minimize consequences arising fr...

This paper presents a method concerning the integration of the benefit/cost analysis and the real genetic algorithm with various elements of reservoir dam design. The version 4.0 of HEC-RAS software and Hydro-Rout models have been used to simulate the region and flood routing in the reservoir of the dam, respectively. A mathematical programming has been prepared in MATLAB software and linked wi...

it is correct control and monitoring of modern embankment dams that are very vital in the geotechniqual constructions. the improvement of methods of stability control, using the effective stress and the measurement of ganglionic water pressure in embankment dams cause more the safety for this kind of dams. nowedays there is such an idea that in stead of using of being safety factor against coas...

OBJECTIVE To describe the culicidae fauna in an area impacted by environmental changes caused by the construction of a dam. METHODS The studied area was the Porto Primavera dam construction site in Southeastern Brazil. Monthly culicidae samples were taken in six exploratory sites in the pre-filling period and in one fixed site, one year before (1997-1998) and after the first filling (1999-200...

Dam safety assessments rely on the skill and experience of dam engineers but such expertise is not always easily transferred to new staff or conveyed in written reports. Many old dams have outlived their creators and puzzle those that see them for the first time. Eliane Alves Portela and Joao Bento explain how expert system technology can help avoid this DAM construction started over 2000 years...

The Miami Conservancy District built five flood control dams after the catastrophic flood of 1913 in Dayton, Ohio. Lockington Dam was one of these five hydraulic fill structures. The Ohio State Department of Natural Resources (ODNR) issued new regulations in 1981 requiring that design flood for class I dams be considered equal to the Probable Maximum Flood (PMF). Flood routing studies performed...
