Abstract
Ilam is located through mountains; therefore, every heavy rain develops a flooding in the city. For
example, in October 29, 2015, a 189 millimeter raining created a disaster leaving more than 17 million
dollars financial loss and 7 casualties. Thisresearch aimed to determine the aspects, factors and processes
affecting the Ilam’s flooding. Thisis an applied research with descriptive–analytical and survey approach.
A library and reference method used to collect data and apprehend the conditions. Another part of the
research utilized a field approach to collect questionnaire prepared with AHP method, which gave out to
30 professionals. Delphi technique was used for distribution among the sample size. The AHP method
used again to find out the aim of the paper. The method entailed aspects (natural, somatic, economic,
management,social - cultural), variables weighted according to expert’s opinions. Also, the importance of
variables asked from professionals through a questionnaire. The attempt to analyze the data, aspects and
indicators compared two by two using Expert Choice software. Among the selected indicators (natural,
somatic, economic, management, social - cultural), the class of management indicators deemed most
important by professionals (weight of 0.343). Natural and somatic indicators rated second and third. The
experts weighed the economic and social – cultural indicators 0.134 and 0.162 respectively putting them
in the fourth and fifth rate with least importance on flooding. Therefore, all the selected aspects and
indicators were effective on Ilam’s flooding and their impacts degree determined.
