Economical integration of permanent and emergency flood control options is a long-standing problem in water resources planning and management. A two-stage linear programming formulation of this problem is proposed and demonstrated which provides an explicit economic basis for developing integrated floodplain management plans. The approach minimizes the expected value of flood damages and costs,...

JOURNAL OF CONTEMPORARY WATER RESEARCH & EDUCATION The Great Midwest Flood of 1993 brought the attention of the nation to the challenges it faced in dealing with floods. Over a sixmonth period, the ravages of the flood were shown nightly on television and filled columns in the print media. East–West transportation networks throughout the Midwest were severely disrupted and more than 100,000 peo...

When heavy rainfall follows herbicide application, the intense surface runoff causes stream water contamination. Aquatic organisms are then briefly exposed to a complex mixture of contaminants. The aim of the present study is to investigate the genotoxic impact of such events on fish. A model fish, the Crucian carp (Carassius carassius) was exposed in controlled conditions, for 4 days, to water...

Flooding is a natural hazard. In this regard, the topic of floodprone area management being actively explored. The study issue combination two aspects - environmental and economic. economic assessment consequences flooding single cost model based on an criterion. Characteristics such as depth, duration rate have greatest influence severity subsequent damage. Standard damage tables are usually s...

An increase of urban flood risks is expected for the following decades not only because climate is becoming more extreme, but also because population and asset densities in cities are increasing. There is a need for models that can explain the damage process of urban flooding and support damage prevention. Recent improvements in flood modeling have highlighted the importance of urban topography...

Constructing of control structures, like dams, change temporal and spatial unequal distribution of water ,and also play an effective role in reduce or eliminate of damage that caused by floods. So reservoir dam’s effect on floods discharges reduction must be determined. In this study the rain Information and flood hydrographs were used to check the flood routing for previous period of Maroon da...

Large numerical calculations are made to get a prediction what damage a possible flood would cause. These results of the simulation are used to prevent further flood catastrophes. The more realistic a visualization of these calculations is the more precaution will be taken by the local authority and the citizens. This paper describes a tool and techniques to get a realistic looking, three-dimen...

In the aftermath of the severe flooding in Central Europe in August 2002, a number of changes in flood policies were launched in Germany and other European countries, aiming at improved risk management. The question arises as to whether these changes have already had an impact on the residents’ ability to cope with floods, and whether flood-affected private households are now better prepared th...
