An Experimental Analysis of Resilience in Urban Flood Management in the Taipei Basin
Resilience in Space: An experimental analysis of resilience in urban flood management in the Taipei Basin Hsu Chia Sui Email: [email protected] Thesis Supervisor: Kimberly Nicholas Email: [email protected] A thesis submitted in partial fulfillment of the requirements of the Lund University International Master’s Programme in Environmental Studies and Sustainability Science (LUMES), May 2011 Abstract The existing paradigm of flood management in the Taipei Basin prioritizes structural measures over non-structural measures. This strategy is not sufficiently flexible, particularly in light of increasingly frequent extreme weather. Resilience theory is concerned with the capacity of a system to absorb disturbance and retain its same functions. This study offers new insight by conceptualizing resilience in urban flood management. In particular, it demonstrates to what extent resilience theory as used in research on social-ecological systems was useful in developing a better plan for urban flood management. The study comprises a resilience assessment of flood management in Taipei based on guidelines in a workbook for scientists published by the Resilience Alliance. This study identified the external shocks to the flood management system in the Taipei Basin include typhoons, evidence of increasingly frequent extreme weather, groundwater mining and resulting land subsidence, and rapid urbanization. This study also includes a historical profile of major flooding and hydraulic projects from 1960 to 2010 and analyzes phases in terms of an adaptive cycle. The study concludes that resilience theory was an effective approach to investigating external shocks and stress to the system. Furthermore, the qualitative approach to apply resilience was a useful discourse for envisioning a better urban flood management system. -
Toward the Establishment of a Disaster Conscious Society
Special Feature Consecutive Disasters --Toward the Establishment of a Disaster Conscious Society-- In 2018, many disasters occurred consecutively in various parts of Japan, including earthquakes, heavy rains, and typhoons. In particular, the earthquake that hit the northern part of Osaka Prefecture on June 18, the Heavy Rain Event of July 2018 centered on West Japan starting June 28, Typhoons Jebi (1821) and Trami (1824), and the earthquake that stroke the eastern Iburi region, Hokkaido Prefecture on September 6 caused damage to a wide area throughout Japan. The damage from the disaster was further extended due to other disaster that occurred subsequently in the same areas. The consecutive occurrence of major disasters highlighted the importance of disaster prevention, disaster mitigation, and building national resilience, which will lead to preparing for natural disasters and protecting people’s lives and assets. In order to continue to maintain and improve Japan’s DRR measures into the future, it is necessary to build a "disaster conscious society" where each member of society has an awareness and a sense of responsibility for protecting their own life. The “Special Feature” of the Reiwa Era’s first White Paper on Disaster Management covers major disasters that occurred during the last year of the Heisei era. Chapter 1, Section 1 gives an overview of those that caused especially extensive damage among a series of major disasters that occurred in 2018, while also looking back at response measures taken by the government. Chapter 1, Section 2 and Chapter 2 discuss the outline of disaster prevention and mitigation measures and national resilience initiatives that the government as a whole will promote over the next years based on the lessons learned from the major disasters in 2018. -
The St·Ructural Evolution Oftyphoo S
NSF/ NOAA ATM 8418204 ATM 8720488 DOD- NAVY- ONR N00014-87-K-0203 THE ST·RUCTURAL EVOLUTION OFTYPHOO S by Candis L. Weatherford SEP 2 6 1989 Pl.-William M. Gray THE STRUCTURAL EVOLUTION OF TYPHOONS By Candis L. Weatherford Department of Atmospheric Science Colorado State University Fort Collins, CO 80523 September, 1989 Atmospheric Science Paper No. 446 ABSTRACT A three phase life cycle characterizing the structural evolution of typhoons has been derived from aircraft reconnaissance data for tropical cyclones in the western North Pacific. More than 750 aircraft reconnaissance missions at 700 mb into 101 northwest Pacific typhoons are examined. The typical life cycle consists of the fol lowing: phase 1) the entire vortex wind field builds as the cyclone attains maximum intensity; phase 2) central pressure fills and maximum winds decrease in association with expanding cyclone size and strengthening of outer core winds; and phase 3) the wind field of the entire vortex decays. Nearly 700 aircraft radar reports of eyewall diameter are used to augment anal yses of the typhoon's life cycle. Eye characteristics and diameter appear to reflect the ease with which the maximum wind field intensifies. On average, an eye first appears with intensifying cyclones at 980 mb central pressure. Cyclones obtaining an eye at pressures higher than 980 mb are observed to intensify more rapidly while those whose eye initially appears at lower pressures deepen at slower rates and typ ically do not achieve as deep a central pressure. The eye generally contracts with intensification and expands as the cyclone fills, although there are frequent excep tions to this rule due to the variable nature of the eyewall size. -
Notable Tropical Cyclones and Unusual Areas of Tropical Cyclone Formation
A flood is an overflow of an expanse of water that submerges land.[1] The EU Floods directive defines a flood as a temporary covering by water of land not normally covered by water.[2] In the sense of "flowing water", the word may also be applied to the inflow of the tide. Flooding may result from the volume of water within a body of water, such as a river or lake, which overflows or breaks levees, with the result that some of the water escapes its usual boundaries.[3] While the size of a lake or other body of water will vary with seasonal changes in precipitation and snow melt, it is not a significant flood unless such escapes of water endanger land areas used by man like a village, city or other inhabited area. Floods can also occur in rivers, when flow exceeds the capacity of the river channel, particularly at bends or meanders. Floods often cause damage to homes and businesses if they are placed in natural flood plains of rivers. While flood damage can be virtually eliminated by moving away from rivers and other bodies of water, since time out of mind, people have lived and worked by the water to seek sustenance and capitalize on the gains of cheap and easy travel and commerce by being near water. That humans continue to inhabit areas threatened by flood damage is evidence that the perceived value of living near the water exceeds the cost of repeated periodic flooding. The word "flood" comes from the Old English flod, a word common to Germanic languages (compare German Flut, Dutch vloed from the same root as is seen in flow, float; also compare with Latin fluctus, flumen). -
On Tropical Cyclones
Frequently Asked Questions on Tropical Cyclones Frequently Asked Questions on Tropical Cyclones 1. What is a tropical cyclone? A tropical cyclone (TC) is a rotational low-pressure system in tropics when the central pressure falls by 5 to 6 hPa from the surrounding and maximum sustained wind speed reaches 34 knots (about 62 kmph). It is a vast violent whirl of 150 to 800 km, spiraling around a centre and progressing along the surface of the sea at a rate of 300 to 500 km a day. The word cyclone has been derived from Greek word ‘cyclos’ which means ‘coiling of a snake’. The word cyclone was coined by Heary Piddington who worked as a Rapporteur in Kolkata during British rule. The terms "hurricane" and "typhoon" are region specific names for a strong "tropical cyclone". Tropical cyclones are called “Hurricanes” over the Atlantic Ocean and “Typhoons” over the Pacific Ocean. 2. Why do ‘tropical cyclones' winds rotate counter-clockwise (clockwise) in the Northern (Southern) Hemisphere? The reason is that the earth's rotation sets up an apparent force (called the Coriolis force) that pulls the winds to the right in the Northern Hemisphere (and to the left in the Southern Hemisphere). So, when a low pressure starts to form over north of the equator, the surface winds will flow inward trying to fill in the low and will be deflected to the right and a counter-clockwise rotation will be initiated. The opposite (a deflection to the left and a clockwise rotation) will occur south of the equator. This Coriolis force is too tiny to effect rotation in, for example, water that is going down the drains of sinks and toilets. -
Black-Faced Spoonbill, Spoon-Billed Sandpiper and Chinese Crested Tern
Convention on the Conservation of Migratory Species of Wild Animals Secretariat provided by the United Nations Environment Programme 14 th MEETING OF THE CMS SCIENTIFIC COUNCIL Bonn, Germany, 14-17 March 2007 CMS/ScC14/Doc.16 Agenda item 5.1 PROGRESS REPORT ON THE INTERNATIONAL ACTION PLANS FOR THE CONSERVATION OF THE BLACK-FACED SPOONBILL ( PLATALEA MINOR ), SPOON-BILLED SANDPIPER ( EURYNORHYNCHUS PYGMEUS ), AND CHINESE CRESTED-TERN ( STERNA BERNSTEINI ) (Prepared by Mr. Simba Chan, BirdLife International Asia Division) I. Progress to March 2007 1. Preparation of the International Action Plans (IAP) for Black-faced Spoonbill, Chinese Crested-tern and Spoon-billed Sandpiper was unofficially started in late 2004, when BirdLife International Asia Division contacted experts on these species for their involvement in drafting the IAPs. As BirdLife International and its partners in Asia have been involved in conservation activities of Black-faced Spoonbill and Chinese Crested-tern, we believe it is best to have these two species IAP coordinated under BirdLife International Asia Division. On the IAP for Spoon- billed Sandpiper, BirdLife International approached the Shorebird Network of the Asia- Australasian Flyway for cooperation. They recommended Dr Christoph Zöckler, a Spoon-billed Sandpiper expert, to be the coordinator. BirdLife International had discussed with Dr Zöckler several times since 2004 and finally signed an agreement regarding the IAP after signing the Letter of Agreement with the CMS in early 2006. Black-faced Spoonbill Platalea minor 2. Drafting of the IAP for Black-faced Spoonbill goes on smoothly, with four working meetings between compilers who represent all major range countries (Japan, North Korea, South Korea, China including the island of Taiwan and the Hong Kong Special Administration Region) and workshop and symposia held in Tokyo, Tainan (Taiwan), Hong Kong and Ganghwa (South Korea): Tokyo, Japan : 2-6 October 2005 Meeting during the BirdLife Asia Council Meeting and a workshop at the Korea University, Tokyo. -
Boreal Summer Intraseasonal Oscillation Impact on Western North Pacific Typhoons and Rainfall in Taiwan
Terr. Atmos. Ocean. Sci., Vol. 27, No. 6, 893-906, December 2016 doi: 10.3319/TAO.2016.05.30.01(A) Boreal Summer Intraseasonal Oscillation Impact on Western North Pacific Typhoons and Rainfall in Taiwan Chih-wen Hung1, *, Ho-Jiunn Lin1, Pei-ken Kao 1, Ming-Fu Shih1, and Wei-yi Fong 2 1 Department of Geography, National Taiwan Normal University, Taipei City, Taiwan, R.O.C. 2 Department of Geography, National Taiwan University, Taipei City, Taiwan, R.O.C. Received 22 January 2016, revised 26 April 2016, accepted 30 May 2016 ABSTRACT This study discusses the boreal summer intraseasonal oscillation (BSISO) impact on the western North Pacific (WNP) typhoons and the summer rainfall in Taiwan. The real time BSISO1 and BISISO2 indices are created using the first two and the third and fourth principal components of the multivariate empirical orthogonal function analysis, based on outgoing long-wave radiation and zonal wind at 850 hPa from Lee et al. (2013). The results show that heavy rainfall in Taiwan and the associated WNP typhoon frequency patterns are closely related to the 10 - 30 days BSISO2 phases during the typhoon season (July - October). Taiwan has larger rainfall during BSISO2 phases 3, 4, and 5 when the major BSISO2 convection moves northwestward from the Philippine Sea to the Taiwan area. During phases 3 and 4 the anomalous low-level cyclonic flow and the increased typhoon frequency directly result in larger rainfall in Taiwan. Phase 5 exhibits enhanced low-level southwesterly flow which transports the moisture to Taiwan responsible for more summer rainfall on the island. -
Super Typhoon HAIYAN Crossed the Philippines with High Intensity in November 2013 Dr
Super typhoon HAIYAN crossed the Philippines with high intensity in November 2013 Dr. Susanne Haeseler, Christiana Lefebvre; updated: 13 December 2013 Introduction Super typhoon HAIYAN, on the Philippines known as YOLANDA, crossed the islands between the 7th and 9th November 2013 (Fig. 1 to 3). It is classified as one of the strongest typhoons ever making landfall. The storm surge, triggering widespread floods, and winds of hurricane force caused by HAIYAN wreaked havoc. In this connection, HAIYAN bears much resemblance to a typhoon in the year 1912, even with respect to the effects (see below). Fig. 1: Infrared satellite image of typhoon HAIYAN being located across the Philippines, acquired on 8 November 2013, 09 UTC. Up to 5 m high waves hit the coastal areas. Ships capsized, sank or ran aground. In Tacloban, the capital of the province of Leyte, even three bigger cargo ships were washed on the land. Numerous towns were partly or totally destroyed. Trees were blown down. There were power outages and the communication was knocked out. Destroyed streets and airports hampered the rescue work and further help. Hundreds of thousands of people lost their homes. Although many people sought shelter, thousands lost their lives. 1 The National Disaster Risk Reduction and Management Council (NDRRMC) of the Philippines provided the following information about the effects of the typhoon in the Situational Report No. 61 of 13 December 2013, 6:00 AM, which changed daily even 5 weeks after the event: ▪ 6 009 were reported dead (as of 13 December 2013, 6 AM) ▪ 27 022 injured (as of 13 December 2013, 6 AM) ▪ 1 779 are still missing (as of 13 December 2013, 6 AM) ▪ 3 424 190 families / 16 076 360 persons were affected ▪ out of the total affected, 838 811 families / 3 927 827 persons were displaced and served by evacuation centres ▪ 1 139 731 houses (550 904 totally / 588 827 partially) were damaged. -
