Abstract ▼ AI-Helper

Over the last several decades, the United States has experienced a great number of natural disasters. To minimize the impact of the natural hazard events, the U.S. government spent a tremendous amount of money through federal assistant programs. To be eligible for the programs, a mitigation project must be cost effective (more benefits compared to project costs). However, the state and local communities suffering from the natural disasters generally have difficulty in collecting reliable evidence for their damages which can be converted later into benefits when a mitigation project is implemented. Therefore, this paper shows the process of conducting a benefit cost analysis with limited data. Besides, it also provides how to apply the limited data to the analysis through a case study. Consequently, this paper help state and local communities get funding from the federal government, which in turns will improve the image of construction industry by preventing people from natural disasters.

문제 정의

The primary purpose of this paper is to provide an alternative method to conduct benefit cost analysis (BCA) with limited data in selecting natural hazard mitigation capital improvement projects. The BCA is a technique used to determine the relative project benefits compared to total project costs.
This paper examined the method for conducting benefit cost analysis with limited data to help state and local communities determine whether to proceed with natural hazard mitigation capital improvement project. Through a case study this paper showed the basic process of conducting a benefit cost analysis with limited data.

제안 방법

These two openings are frequently dammed up with debris and increase the peak discharge of the water, which causes the flooding and damage to the homes. The proposed alternative involves (1) removing two 96-inch diameter culverts, associated concrete wing walls, and concrete road structure; (2) excavating and cleaning the channel so that it is restored to its natural condition as much as possible, and (3) installation of a structure that permits vehicles to cross the channel. The detailed scope of the project includes below:
2007, April 2007, June 2007, May 2008 and June 26th, 2007 [Table 3]. Once the rainfall amount was identified through the National Climatic Data Center (NCDC), the frequency of the event was determined by comparing the rainfall data with the USGS Atlas of Depth Duration Frequency. Based on flooding or near flooding (Jan.
This paper examined the method for conducting benefit cost analysis with limited data to help state and local communities determine whether to proceed with natural hazard mitigation capital improvement project. Through a case study this paper showed the basic process of conducting a benefit cost analysis with limited data. In addition, it also suggested how to collect reliable evidences that prove damages resulting from the natural disasters.

대상 데이터

Corps of Engineers HEC-RAS modeling program. The flow data was taken from the 2008 FIS study for the Bell County.
The culvert bridge is overtopping for all storm events modeled: 10YR, 50YR, 100YR and 500YR. A 40-ft wide bridge opening was also modeled to replace the existing culvert.

이론/모형

These were imported into ArcGIS and an input geometry file was created using HECGeo-RAS. A hydraulic model was created using the U.S. Corps of Engineers HEC-RAS modeling program. The flow data was taken from the 2008 FIS study for the Bell County.

성능/효과

3. Determine benefit cost ratio: the quantified project benefits and costs in previous steps are compared to produce the BCR. A planned project with the ratio of greater than 1 is typically considered to be cost effective project.
