“…In 1990s, the US Army Corps of Engineers used relationships between damage, frequency, discharge, and stage to develop a hydroeconomic model for the estimation of expected annual damage (EAD) [Plazak, ; Yoe, ; US Army Corps of Engineers (USACE), ]. These correlations work as long as flow conditions and societal vulnerability remain unchanged, which is rarely possible when structural measures are introduced.…”

An appropriate distribution of flood losses over time span may dampen the degree of disruption. Flood insurance is one of the effective ways in order to cope with the aftermaths of flood events. In the absence of an acceptable risk-based assessment framework, flood insurance and its extensive benefits are not fully achieved yet. Consequently, flood insurance is trivially practiced worldwide. To ensure the integration of flood insurance into regular flood management practices, its acceptability by floodplain inhabitants is a prerequisite. Therefore, an admissible insurance rate is a vital factor for the acceptability of insurance policy. This article introduces a risk-based methodology to calculate insurance rate. Normally, insurance rates are based on historic flood events or on a specific design flood. Expected annual damages distribution map (EADDM) is developed to assess spatial distribution of risk. Distribution of flood losses against a specific flood is compared with EADDM. The impacts of both approaches on insurance provider and insured are studied. Single flood approach ignores the impacts because of other floods. Therefore, insurance rates based on single flood are not justifiable. The proposed framework not only facilitates risk-based insurance rate calculation but also endorse flood insurance acceptability. Collins and Simpson, 2007). The implementation of flood insurance is mostly supported by legal provisions, public incentives, and enforcement practices. For example, in the United States, no mortgage lenders that are federally bs_bs_banner J Flood Risk Management 7 (2014) 291-307

Flood discharge capacity in a dam downstream reach has been decreased after dam construction because of the river cross section reduction impacted by farm lands, sand-bars and parking lots, etc. in river flood plains. Those obstacles being in the river inside areas have caused negative influences to the dam operation policy. Therefore, the dam downstream river improvement work associated with the dam operation improvement plan is under construction for removing reduction factors on the dam effective storage, assuring flood safety in the dam downstream river and incrementing dam operation benefits. But the project has issued some problems such as project feasibility, economic evaluation, cost allocation and benefit share, etc. Since a dam enterpriser has not committed such kind of project before, it is necessary to set up an objective analysis process and a quantitative financial valuation. This study examines the measurable economic benefits and the cost allocation of the project for the fairness between benefit owners (central government and water electricity enterprisers). As a result, the total economic benefit from 3 dams (Imha, Daechung and Youngdam Dam) accounts for 14.41 Billion Won/year. The financial valuation of K-water as a project enterpriser is approximately estimated at 40% of the total value and the government is 60%.
