Application of Remote Sensing and GIS for Flood Hazard Management: A Case Study from Sindh Province, Pakistan

American Journal of Geographic Information SystemAmerican Journal of Geographic Information System, Volume 2, Number 1, February 2013

Kabir Uddin, Deo Raj Gurung, Amarnath Giriraj, and Basanta Shrestha

“Floods are one of the most common hazards in the world, affecting people’s lives and livelihoods. Flood hazard mapping and flood shelters suitability analysis are vital elements in appropriate land use planning for flood-prone areas. This paper describes application of Remote Sensing (RS) and Geographical Information Systems (GIS) in identifying flood hazard zones and flood shelters and are therefore important tools for planners and decision makers. The purpose of this article is to describe a simple and efficient methodology to accurately delineate flood inundated areas, flood-hazard areas, and suitable areas for flood shelter to minimize flood impacts. Possible extent of flooding and suitable location flood shelter sites were modeled and mapped for Sindh Province in Pakistan, using the software ArcGIS model builder.

Flow diagram of flood shelter analysis

Flow diagram of flood shelter analysis

“The output was validated using inundation maps based on flood events that took place in 2010 in Pakistan. These were mapped using object-based image analysis (OBIA) implemented in eCognition software. The catastrophic flood of 2010 inundated a total area of 7579 km2, while the modeled result indicated the hazard area to be 6216 km2 out of 46138 km2. Discrepancies in modeled and mapped results are insignificant and acceptable considering the manual flood management interventions which are beyond the capability of models to represent. Thus, this method is robust enough to develop flood hazard zoning maps and map shelter sites for flood management. ”

A Study of Morphological Changes in the Coastal Areas and Offshore Islands of Bangladesh Using Remote Sensing

American Journal of Geographic Information SystemAmerican Journal of Geographic Information System, 2013; 2(1): 15-18

M. Shamsul Alam and Kabir Uddin

“Bangladesh is a country where 80 percent of the land is below 1 meters from the MSL. The small country with a huge population is already known to the outside world for her vulnerability to natural hazards. Among the impacts of climate change, the serious concern for Bangladesh is the relative sea level rise (RSLR). A 45-centimeter sea level rise in Bangladesh may dislocate about 35 million people from 20 coastal districts by 2050. In a worst-case scenario, Bangladesh could lose nearly 25 percent of its 1989 land area by around 2100. The process of erosion, deposition and accretion are common phenomenon in the deltaic country.

Morphological Changes in the Coastal Areas of Bangladesh, 1977-2010

Morphological Changes in the Coastal Areas of Bangladesh, 1977-2010

“This study based on remote sensing data tries to examine the erosion, accretion and net gain/loss of land in the Coastal Areas and Offshore Islands of Bangladesh and recommends measures to enhance the process of accretion to save millions from becoming environmental refugees.”

A Highly Aggregated Geographical Distribution of Forest Pest Invasions in the USA

Diversity and DistributionsDiversity and Distributions, 2013

Liebhold, Andrew M.; McCullough, Deborah G.; Blackburn, Laura M.; Frankel, Susan J.; Von Holle, Betsy; Aukema, Juliann E.

Aim:  Geographical variation in numbers of established non-native species provides clues to the underlying processes driving biological invasions. Specifically, this variation reflects landscape characteristics that drive non-native species arrival, establishment and spread. Here, we investigate spatial variation in damaging non-native forest insect and pathogen species to draw inferences about the dominant processes influencing their arrival, establishment and spread.
Location:  The continental USA, including Alaska (Hawaii not included).
Methods: We assembled the current geographical ranges (county-level) of 79 species of damaging non-indigenous forest insect and pathogen species currently established in the continental USA. We explored statistical associations of numbers of species per county with habitat characteristics associated with propagule pressure and with variables reflecting habitat invasibility. We also analysed relationships between the geographical area occupied by each pest species and the time since introduction and habitat characteristics.

Variables associated with habitat invasibility measured at the county-level: (a) forested land area; (b) numbers of tree species detected in FIA surveys; (c) numbers of tree families detected in FIA surveys; (d) numbers of tree genera detected in FIA surveys.

Variables associated with habitat invasibility measured at the county-level: (a) forested land area; (b) numbers of tree species detected in FIA surveys; (c) numbers of tree families detected in FIA surveys; (d) numbers of tree genera detected in FIA surveys.

Results:  The geographical pattern of non-native forest pest species richness is highly focused, with vastly more species in the north-eastern USA. Geographical variation in species richness is associated with habitat factors related to both propagule pressure and invasibility. Ranges of the non-native species are related to historical spread; range areas are strongly correlated with time since establishment. The average (all species) radial rate of range expansion is 5.2 km yr-1, and surprisingly, this rate did not differ among foliage feeders, sap-feeders, wood borers and plant pathogens.
Main conclusions:  Forest pest species are much more concentrated in the north-eastern region of the USA compared with other parts of the country. This pattern most likely reflects the combined effects of propagule pressure (pest arrival), habitat invasibility (pest establishment) and invasion spread. The similarity in historical spread among different types of organisms indicates the importance of anthropogenic movement in spread.”

Spatial Assessment of Attitudes Toward Tigers in Nepal

AMBIOAMBIO: A Journal of the Human Environment, Published Online 09 July 2013

Neil H. Carter, Shawn J. Riley, Ashton Shortridge, Binoj K. Shrestha, and Jianguo Liu

“In many regions around the world, wildlife impacts on people (e.g., crop raiding, attacks on people) engender negative attitudes toward wildlife. Negative attitudes predict behaviors that undermine wildlife management and conservation efforts (e.g., by exacerbating retaliatory killing of wildlife). Our study (1) evaluated attitudes of local people toward the globally endangered tiger (Panthera tigris) in Nepal’s Chitwan National Park; and (2) modeled and mapped spatial clusters of attitudes toward tigers. Factors characterizing a person’s position in society (i.e., socioeconomic and cultural factors) influenced attitudes toward tigers more than past experiences with tigers (e.g., livestock attacks).

Maps showing percentage of respondents per ward that (a) had <8 years of education, (b) were from lower caste Hindu and Terai Tibeto-Burmese ethnic groups, (c) were female, and (d) reported that a tiger had threatened/attacked a family member in the past. Percentage categories were defined by equal intervals.

Maps showing percentage of respondents per ward that (a) had

“A spatial cluster of negative attitudes toward tigers was associated with concentrations of people with less formal education, people from marginalized ethnic groups, and tiger attacks on people. Our study provides insights and descriptions of techniques to improve attitudes toward wildlife in Chitwan and many regions around the world with similar conservation challenges.”

Town of Canmore Contracts Advanced Aerial LiDAR Survey to Assess Damage from Southern Alberta Floods

LiDAR Services International Inc.The Town of Canmore, Alberta contracted LiDAR Services International Inc., (LSI), a Calgary based airborne LiDAR mapping company to mobilize their advanced helicopter equipped laser mapping system to conduct an aerial LiDAR and imaging survey of 54 square kilometers of the Bow River valley in the Canmore area to assess damage as a result of the 2013 Alberta floods. The mountain town declared a state of local emergency on June 20 as over 220 millimeters of rain fell in 36 hours, nearly half of Canmore’s annual average rainfall on already saturated ground, coupled with a steep mountain watershed, resulted in a rapid increase in the size and flow of several rivers. The normally tranquil Cougar Creek raged, spilling over its banks, washing away roadways, a rail line, pathways and destroying swaths of green space and creek side homes.

“A tremendous amount of material has been swept off the mountain … rocks, dirt, soil, boulders and trees …into Cougar Creek and depositing the material in the Town of Canmore causing several homes to be destroyed and taking out the Trans-Canada Highway and a CP Rail line,” said Blair Birch, P. Eng., Municipal Engineer , Town of Canmore.

The flood initiated the need for the LiDAR survey … the Town contracts the collection of aerial ortho photos every five years, however, the flood created the immediate need for accurate, detailed topographic data that LiDAR can provide. “The LiDAR survey will capture where the water caused the greatest damage …where water courses were rerouted, how the hydrology of the watershed has been altered. The survey’s topographic data and imagery will assist in studying what happened and how to mitigate these events in the future,” said Birch. “We need to establish how much debris came down from the mountain and was deposited in the Town. The LiDAR will help to reestablish new watersheds and hydrological assessments and will also be helpful in applying for relief funds from federal and provincial governments.” “We used a Bell 206B helicopter to allow us to fly low and slow over the survey area in mountainous terrain to provide a very high accuracy data set of both LiDAR and imagery data,” said Tony Tubman, president, LSI. “We are very pleased to be able to respond to the Town of Canmore and its residents on such short notice in their time of need …there has been a lot of devastation as a result of the2013 Alberta flood …and we are happy to be a part of the relief effort.” LSI has expedited processing of the LiDAR and imagery data to get it to the Town of Canmore as soon as possible. Turning around the delivery of such huge volumes of collected data which normally takes several weeks to days is a testament to the commitment LSI has made to Canmore.

The aerial LiDAR survey deliverables include LiDAR point clouds classified to Ground, DTM Keypoints, Low Vegetation and High Vegetation classes; Bare Earth and Full Feature grids at 1 m spacing; Greyscale hillshades of Bare Earth and Full Feature surfaces at 1 m pixel resolution; and Ortho-mosaicked color digital imagery mapped at a 10 cm pixel resolution. The Town of Canmore has a full-time population of 17,000 but that can double during the winter ski and summer tourist seasons. TheTown attracts world-class athletes to its Nordic Centre. Officials are now conducting an overall assessment in the area to determine the full extent of the damage. With the local state of emergency in Canmore lifted, attention is turning toward ways to fix up Cougar Creek — the small but powerful stream that has breached its banks for the second time in two years – as well as several other stream courses entering Town.
