Abstract Following Hurricane Katrina, the US Army Corps of Engineers, supported in part by the risk and reliability analysis conducted by the Interagency Performance Evaluation Task Force (IPET), made a major shift from ‘protection’ to ‘risk reduction’ as the principal goal in flood mitigation. The mitigation of the flood risk in Southeast Louisiana was embodied in the design and construction of the ‘Hurricane and Storm Damage Risk Reduction System’, the post-Katrina initiative for New Orleans flood mitigation. It also spawned a major overhaul of many of the Corps of Engineers’ technical guidance and engineering practice documents, incorporating risk as a key measure in the planning and design processes. The criteria applied for the design of the HSDRRS are discussed, with summaries of the associated major changes in Corps engineering guidance and practice relevant to flood mitigation.

This study used remote sensing techniques to identify and assess the current condition of bottomland hardwood (BLH) and swamp habitats within the West Shore Lake Pontchartrain (WSLP) hurricane storm-damage risk reduction system (HSDRRS) project area. This effort provides baseline knowledge of the location and quality of these habitats prior to the construction of the WSLP HSDRRS project. The resultant products will assist the USACE—New Orleans District (MVN) by informing ecosystem decision-making related to environmental assessments.

Hurricane Katrina caused unprecedented flood damage to New Orleans, Louisiana, and has been the costliest hurricane in US history. We analyzed the environmental and public health outcomes of Hurricane Katrina by using Internet searches to identify epidemiological, sociodemographic, and toxicological measurements provided by regulatory agencies. Atmospheric scientists have now warned that global warming will increase the proportion of stronger hurricanes (categories 4–5) by 25% to 30% compared with weaker hurricanes (categories 1–2). With the new $14.6 billion Hurricane Storm Damage Risk Reduction System providing a 100-year storm surge–defensive wall across the Southeast Louisiana coast, New Orleans will be ready for stronger storms in the future.

Damage Risk

Abstract. The derivation of probabilities of high wind speeds and the establishment of risk curves for storm damage is of prime importance in natural hazard risk analysis. Risk curves allow the assessment of damage being exceeded at a given level of probability. In this paper, a method for the assessment of winter storm damage risk is described in detail and applied to the German state of Baden-Württemberg. Based on meteorological observations of the years 1971–2000 and on damage information of 4 severe storm events, storm hazard and damage risk of residential buildings is calculated on the level of communities. For this purpose, highly resolved simulations of storm wind fields with the Karlsruher Atmospheric Mesoscale Model (KAMM) are performed and a storm damage model is developed. Risk curves including the quantification of the uncertainties are calculated for every community. Local differences of hazard and risk are presented in state-wide maps. An average annual winter storm damage to residential buildings of minimum 15 million Euro (reference year 2000) for Baden-Württemberg is expected.

ABSTRACTDepok City has a function as a water catchment in reducing flooding in Jakarta City and in Depok City itself, the existence of existing sites is very important to be maximized. At present there are only 21 small lake in Depok City whose existence is still maintained. The conditions there each year decrease both in terms of quality and quantity. There are 6 small lake in Cimanggis subdistricts, namely: Situ Gadog, Situ Pedongkelan, Situ Rawa Kalong, Situ Tipar, Situ Jemblung, and Situ Rawa Gede, which as a whole have an area of 32.4 Ha. To maintain small lake preservation in the Cimanggis sub-district, damage risk reduction is urgently needed to sustain the small lake's existence in a sustainable manner. There are 5 variables of community participation in damage risk reduction in Cimanggis sub-district. Five variables to measure the level of community participation are community participation in the form of thoughts, community participation in the form of property, community participation in the form of energy, community participation in the form of skills, and community participation in social forms.

Abstract About 70 million m3 was damaged by the storm Gudrun that hit southern Sweden in January 2005, i.e. almost as much as the normal annual cut for the whole country. To establish any differences in forest state and forest management before and after the storm, measures such as growing stock, annual growth, age-class distribution, choice of species in regeneration and cleaning and thinning activities were studied for the area affected and the area unaffected by the storm. For all analyses, sample plots from the Swedish National Forest Inventory were used. Results based on mean values for the periods 2000–2004/2006–2010/2012–2016 showed that the total growing stock for the damaged area decreased significantly by ~30 million m3 directly after the storm but has now recovered to the same level as before the storm. Therefore, it seems clear that forest owners and forest managers made rational choices when aiming to restore the forest area. As expected , the annually cleaned area and the area in immediate need of cleaning increased significantly in the Gudrun area after the storm. No other significant changes in behaviour to reduce future storm damage risk could be detected.

Southwest Border

A selection forest covering about 500 ha in Schwarzenegg, on the southwest border of the Bernese Emmental, was subjected to areal and random spot checks in order to investigate dependencies between the damage caused by Lothar and various factors. Over the entire area 18% of the stems and 24% of the reserve stock is damaged. Worst hit are the acid and wet sites or low-lying sites. Selection sites are less effected than conversion stands and these less than even-aged stands. According to species, damage is significantly higher for spruce than for fir,and higher for fir than for beech. Yield intervention on sites up to 5 years before and between 15 and 20 years before the storm led to greater damage than intervention taken 5 to 15 years before the storm. Average strengths of interference between 70 to 150 sv/ha were less destabilising than weaker or stronger interference, regardless of how long before the storm they were carried out. It seems that, as far as risk reduction is concerned, selection forest is to be preferred to even-aged forest,as, in addition, permanent rejuvenation phases occur in selection stands over the whole area, which facilitate the reconstitution of structured stock in case of damage.

Damage Risk

The purpose of this study was to compare the damage risk of 85 and 90 dBA of white noise for equivalent full-day exposures. The damage risk of the two noise levels was determined by comparing the temporary threshold shift (TTS) of 12 subjects exposed to either 85 or 90 dBA of white noise for equivalent half- and full-day exposures. TTS was determined by comparing the pre- and postexposure binaural audiograms of each subject at 1, 2, 3, 4, 6, and 8 kHz. It was concluded that the potential damage risk, that is, hazardous effect, of 90 dBA is greater than 85 dBA of noise for equivalent full-day exposures. The statistical difference between the overall effects of equivalent exposures to 85 dBA as compared to 90 dBA of noise could not be traced to any one frequency. The damage risk of a full-day exposure to 85 dBA is equivalent to that of a half-day exposure to 90 dBA of noise. Within the limits of this study, TTS t was as effective as TTS 2 for estimating the damage risk of noise exposure.
