“…In South Andaman the inundation caused by December 2004 Tsunami was perpetuated by sea level rise [8] (Dharanirajan et al, 2006). Subsidence of the landmass in the earthquake results in rise of sea water level by about one meter [9] (Sudhir et al, 2005).…”

“…In these areas different mangrove species distributed like Avicennia marina, A.officinalis, Rhizophora mucronata, R. Apiculata, Sonneratia alba, Acrostichum aureum, Acanthus illicofolius A. ebracteatus and Xylocarpus molluccenis are widely distributed. During 2006 Earthquake and Tsunami mangroves are severely affected particularly in sippighat are almost dissipated in some areas [8]. The objective of the study is to map the status of mangrove after the sea level rise on flat bay coast by the tsunami and land tilt in study area using Remote Sensing and GIS techniques.…”

“…According to Toposheet the total mangrove in the study area was estimated to be 406.88 ha during 1979 and it rapidly degraded in the last two decades. These mortality conditions for mangroves occur particularly after the 2004 tsunami, it decreased up to 236 ha [8]. Low lying areas of sippighat mangroves is under the threat of erosion, it may due to the tsunami inundation impacts [16].…”

“…Remote sensing imagery has been integrated with GIS techniques to facilitate damage assessment after tsunami invasion in southern Asia, 2004(Kurmar et al 2007). Other studies have pointed out the benefits of using remote sensing imagery to estimate the impact of tsunamis (Liu et al 2007, Bovolo et al 2007, Dharanirajan et al 2007, Sirikulchayanon et al 2008, Kerr et al 2009. A rapid recognition approach for built-up structures has already been developed with applications elaborated in succeeding studies (Voigt et al 2011).…”

Remote sensing technologies have been applied to numerous fields and already benefited those in improving efficiency and recognition accuracy. Change of streamflow can be devastating to residents living along riversides. Still it is difficult to detect such deathly change in large area scale by traditional field surveys. The research aims at provision of detecting streamflow change using a mathematic method based on remote sensing technologies. The scope is on remote sensing stream images taken during the invasion by Typhoon Morakot, bringing one of the major catastrophes to Taiwan. An algorithm was adopted to deal with streamflow recognition on RGB images. The algorithm is capable of yielding change measured by meters and illustrates how main streams shift. An practical example for the Baolai area surrounded by Laonong stream shows that the streamflow moved 88 meters (36 pixels) toward the downtown area during the invasion by Typhoon Morakot. In addition, the results highlight all dangerous zones (scouring zones) for residents to prevent further potential damage.

“…The area impacted, severity of damage, and type of impacts are recognised as essential data for disaster monitoring and response activities in military, government agencies, and community groups (Joyce et al 2009b;Coppola 2006;Dong and Shan 2013).To accurately map the type and severity of damage and use high spatial resolution image data, appropriate mapping and change detection tools are need to replicate what was done manually in the past with air photographs (Joyce et al 2009a). Change detection from classified man-made and natural features of pre-and post-cyclone events is a widely used technique to support these processes in a remote-sensing environment Dharanirajan et al 2007). The new approach provides a map of intensity of impacts for relevant agencies to plan where emergency relief is required (Belward et al 2007;Klemas 2009).…”

Tropical cyclones are one of the most catastrophic natural hazards regularly affecting tropical coastal areas globally. The overall impacts of tropical cyclones can be minimized using a range of management approaches, in terms of: prevention/reduction, and preparedness. Accurate and detailed spatial information on the natural and built environment is required to support the development, implementation and evaluation of these cyclone management approaches. There is a lack of appropriate mapping approaches and spatial models at local scales (<1000 km 2 ) to derive this information.This thesis developed and evaluated mapping approaches and spatial models at the local scale (<1000 km 2 ) by integrating remote sensing, field data and spatial analysis for assessing, monitoring and managing tropical cyclone impacts. Three specific objectives were addressed: (1) developing and evaluating an approach for assessing the multiple impacts of tropical cyclones through objectbased image analysis applied to moderate spatial resolution satellite imagery; (2) developing and testing a risk mapping approach for tropical cyclone impacts using an analytical hierarchy process (AHP) with data derived from remote sensing, field data and spatial analysis; and (3) producing and evaluating a simple risk modelling approach under present and future climate scenarios for tropical cyclone impacts using remote sensing, field data and spatial analysis. The developed mapping approaches and models were tested to justify the applicability in Sarankhola Upazila (151 km 2 ), a local government area in coastal Bangladesh. Cyclone Sidr (2007) was used as a case study for objective one in the study site.After introductory, review and research approach chapters, chapter four developed a method for mapping the multiple impacts of tropical cyclones. The object-based approach was used to map land cover types in pre-and post-cyclone Sidr (2007) damage to cropland and the changes to landforms. The damage results were verified using local damage reports and high spatial resolution satellite imagery that were taken after the cyclone.ii Chapter five integrated remote sensing, field data and spatial analysis for developing a multi-criteria tropical cyclone risk mapping approach at a local scale. Three risk components: 1-vulnerability and exposure; 2-hazard; and 3-mitigation capacity, and their 14 relevant criteria were considered.Thematic raster map layers were prepared for every criterion and weighted using AHP. A weighted overlay technique was used for generating vulnerability, hazard, mitigation capacity and risk maps.The verified results revealed that detailed cyclone risk information can be successfully mapped using geospatial techniques and an AHP at the local scale. The study found that incorporation of mitigation capacity significantly influenced the risk results. The approach also solved several issues for local level multi-criteria data generation, processing and integration. The approach provided was validated by confidence level assessment an...
