Efficient planning for disasters can significantly reduce their adverse impact on the public; however, assigning people to shelters becomes problematic especially while planning for those at-risk populations such as older adults who may need special assistance. In addition, hurricane registries may not reflect the actual number of people with access and functional needs. This can lead to a shelter capacity deficit in a county, which may be mitigated by collaborations among neighboring counties. The overall effectiveness of a cross-county collaboration (compared to the no-collaboration case) in shelter assignment was previously shown using a p-Median model. However, it is also necessary to investigate the cost of such a collaboration at the block group level, which is the main scope of this study. This collaboration cost includes both the cost of being assigned to a farther shelter, and the cost of not being assigned under the collaboration cases. To monitor the total performance of shelter assignment under collaboration, performance measures are developed to evaluate the benefits and cost of this collaboration (i.e., the total number of assigned/ unassigned people, the number of people assigned to farther shelters, the average cost of assignment, the number of people assigned/not assigned under the collaboration). A GIS-based numerical example is provided for 5-county Panhandle region of Florida with a focus on the 85 + population and special needs shelters (SpNS). Results indicate that it is possible to increase the total number of people assigned in the 5-county region by 2-7% using the cross-county collaboration.

Extending interdiction and median models to identify critical hurricane shelters Alişan, Onur; Ulak, Mehmet Baran; Kocatepe, Ayberk; Ozguven, Eren Erman; Horner, Mark; Huang, Wenrui (Elsevier BV, 2020-02-01) Shelters serve as critical facilities where people gather during and after hurricanes. A basic requirement of 'operation' for a shelter is being functional and available to help. However, what happens when shelters themselves are damaged and unable to serve those people? An open question with key policy implications is: How can we identify the most critical shelter(s) as a part of broader emergency evacuation operations and how can we respond to an interdiction? This paper develops a two-step modeling frame...
Seismic Risk Prioritization and Retrofit Cost Evaluation of Code-Deficient RC Public Buildings in Turkey Sucuoğlu, Haluk; Yakut, Ahmet (SAGE Publications, 2015-02-01) A risk prioritization procedure is developed for deficient concrete public buildings within the scope of a seismic risk reduction program. The main purpose is identifying public buildings with high damage risk in a region for efficient retrofit investments. Regularity of structural systems and repeatability of deficiencies in public buildings provide opportunities for developing simple and reliable assessment procedures. The proposed procedure is based on calculating a risk index from the comparison of late...
An analysis of the flood management and mitigation measures in Zimbabwe for a sustainable future Samu, Remember; Kentel, Aysu Sagun (Elsevier BV, 2018-10-01) Floods have prevailed in the recent years, hampering not only social but also the economic development as well. This global pandemic has caused loss of lives, property and economic damages in many countries, including Zimbabwe. Rainfall intensity in the country's seven main river catchments namely; Mzingwane, Gwayi, Save (or Sabi), Mazowe (or Mazoe), Sanyati, Manyame and Runde triggers flash floods due to high peak discharges. It is therefore of paramount importance to try and reduce or rather prevent these...
Stabilization of Expansive Soils by Using Aggregate Waste, Rock Powder and Lime Yeşilbaş, Gülşah; Çokça, Erdal; Department of Civil Engineering (2004) Expansive soils are a worldwide problem that poses several challenges for civil engineers. Such soils swell when given an access to water and shrink when they dry out. The most common and economical method for stabilizing these soils is using admixtures that prevent volume changes. In this study the effect of using rock powder and aggregate waste with lime in reducing the swelling potential is examined. The expansive soil used in this study is prepared in the laboratory by mixturing kaolinite and bentonite....
Performance and Cost of Cross-County Collaboration in Special Needs Shelter (SpNS) Planning Alişan, Onur; Tüydeş Yaman, Hediye (2018) Planning for disasters in advance can significantly reduce their impact on the public; however, it becomes very challenging when dealing with special needs populations and their assignment to shelters. Older populations may also require such special attention, although they may or may not be listed in the registries, since their health conditions may deteriorate rapidly in the aftermath of a disaster. A previous study has shown the benefits of possible cross-county collaboration while assigning older popula...
