nowadays multicriteria decision making (mcdm) methods are a useful tool for investigating natural resources and toaddress problems related to hydro systems. the goal of this research was to assess the daliri standardization method(dsm) to prioritize and make selections for application to mcdm. and to compare the dsm method with the utilityadditive (uta) method. the (dsm) method, unlike the (uta...

It has long been recognized that flood protection provided by levees is a double-edged sword. On one hand, levee systems have provided flood protection. On the other hand, given enough time levees either will be overtopped or will fail—leading to severe flood impacts on an unsuspecting population. Unlike a natural flood, levee failure flooding is often rapid, forceful, extremely damaging, and o...

A number of important misconceptions or fallacies stand in the way of a better understanding of the nation’s flood problem. The fallacies are not universal, with many flood experts, decision makers, and sectors of the public escaping their seductive logic. But enough people do fall prey to these fallacies of floods so as to create obstacles to improved utilization of the lessons of experience. ...

Flood hedging reservoir operation is when a pre-storm release creates a small flood downstream to reduce the likelihood of a more damaging but uncertain larger flood in the future. Such pre-storm releases before a flood can increase reservoir storage capacity available to capture more severe flood flows, but also can immediately increase downstream flood damage and reduce stored water supply. T...

UNLABELLED Flooding is the most common and damaging of all natural disasters in the United States, and was a factor in almost all declared disasters in U.S. HISTORY Direct flood losses in the U.S. in 2011 totaled $8.41 billion and flood damage has also been on the rise globally over the past century. The National Flood Insurance Program paid out more than $38 billion in claims since its incep...

Flooding is one of the most damaging of natural disasters. Structural approaches to flood management consist of reservoirs and dams equipped with floodgates, along with protocols for their operation. However, in spite of the infrastructure being in place, floods can occur because of flaws in the floodgate operation protocols or human error in its implementation. Hybrid automata are a formalism ...

Floods are among the most frequent and costly natural disasters in terms of human hardship and economic loss. In recent years Europe suffered over 100 major damaging floods. Since 1998, floods have caused damages of some 700 facilities, the displacement of about half a million people and at least 25 billion Euro in insured economic losses. In the United States, about 90 percent of the damage ca...
