Physical, Economical, Infrastructural And Social Flood Risk -- Vulnerability Analyses In Gis, Angela Peck, Subhankar Karmakar, Slobodan P. Simonovic

Water Resources Research Report

An exhaustive knowledge of flood risk, vulnerability and exposure in different spatial locations is essential for developing an effective flood mitigation strategy for a watershed. In the present study, a flood risk-vulnerability analysis is performed. All four components of flood vulnerability: (a) physical; (b) economic; (c) infrastructure and (d) social, are evaluated individually using a Geographic Information System (GIS) environment. The proposed methodology estimates the impact on infrastructure vulnerability due to inundation of critical facilities, emergency service stations, and road bridges. The components of vulnerability are combined to determine the overall vulnerability. The patterns of land use and soil type …

A General Overview Of Multi-Objective Multiple-Participant Decision Making For Flood Management, Taslima Akter, Slobodan P. Simonovic

Water Resources Research Report

Decision-making problems in water resources are often associated with multiple objectives and multiple stakeholders. To enable more effective and acceptable decision outcome, it is required that more participation is ensured in the decision making process. This is particularly relevant for flood management problems where the number of stakeholders could be very large. Although application of multi-objective decision-making tools in water resources is very wide, application with the consideration of multiple stakeholders is much more limited. The solution methodologies adapted for multi-objective multi-participant decision problems are generally based on aggregation of decisions obtained for individual decision makers. This approach seems somewhat …

A Spatial Fuzzy Compromise Approach For Flood Disaster Management, Nirupama, Slobodan P. Simonovic

Water Resources Research Report

Natural disasters affect regions with different intensity and produce damages that vary in space. Topographical features of the region; location of properties that may be exposed to the peril; level of exposure; impact of different mitigation measures; are all variables with considerable spatial variability. A new method for evaluation of disaster impacts has been presented in this report that takes into consideration spatial variability of variables involved and associated uncertainty. Flood management has been used to illustrate the utility of proposed approach.

Floodplain management is a spatial problem. Representation of flood damage mitigation alternatives and objectives in space provides a …
