Inviting trouble downstream

Article Abstract:

The giant flood control dams have proven to be ineffective in fulfilling their objectives. Catastrophes are inevitable given the failure of engineers to recognize the weaknesses of flood control reservoirs in flood management planning. Typically, a great flood exceeds the capacity of a reservoir and destroys the levees, which are the last line of defense for cities and industries on a floodplain. Instead of relying solely on dams and levees, a national flood policy should embrace flood management, which should include not only flood control but also land use controls, insurance, floodproofing and emergency planning.

The great Chicago flood of 1992

Article Abstract:

The great Chicago flood of 1992 resulted from the seepage of water into the freight tunnels underneath the city. To avert this dilemma, two modes of action were necessary. The first phase involved plugging operations of the city's tunnel system. After this was successfully done, the dewatering of the affected segments was next. The character of the disaster response is considered as the factor in the success of the whole operation.
