“…Any type of land-use change resulting from urbanization leads to an increase in flooding due to the rise in the rainfall-runoff coefficient (Myronidis et al 2016;Dammalage and Jayasinghe 2019). Preventing floods is complicated, but their occurrence can be predicted and partially controlled using appropriate methods and measures (Mansur et al 2018;Malik and Pal 2020). Having access to accurate and current information is key to preventing floods or at least reducing their harmful effects.…”

Flooding is a natural disaster that causes considerable damage to different sectors and severely affects economic and social activities. The city of Saqqez in Iran is susceptible to flooding due to its specific environmental characteristics. Therefore, susceptibility and vulnerability mapping are essential for comprehensive management to reduce the harmful effects of flooding. The primary purpose of this study is to combine the Analytic Network Process (ANP) decision-making method and the statistical models of Frequency Ratio (FR), Evidential Belief Function (EBF), and Ordered Weight Average (OWA) for flood susceptibility mapping in Saqqez City in Kurdistan Province, Iran. The frequency ratio method was used instead of expert opinions to weight the criteria in the ANP. The ten factors influencing flood susceptibility in the study area are slope, rainfall, slope length, topographic wetness index, slope aspect, altitude, curvature, distance from river, geology, and land use/land cover. We identified 42 flood points in the area, 70% of which was used for modelling, and the remaining 30% was used to validate the models. The Receiver Operating Characteristic (ROC) curve was used to evaluate the results. The area under the curve obtained from the ROC curve indicates a superior performance of the ANP and EBF hybrid model (ANP-EBF) with 95.1% efficiency compared to the combination of ANP and FR (ANP-FR) with 91% and ANP and OWA (ANP-OWA) with 89.6% efficiency.

“…Other adaptation strategies employed in Santarém are the use of bricks to elevate houses and embankments and floor elevation-as observed in other parts of the urban Amazon (Hully et al, 2015;Mansur et al, 2018). These constructs are similarly based on experience (Wang et al, 2018).…”

“…A diverse literature on these matters has contributed significantly to the understanding of the authors (see, for example, Adger et al, 2007;Bird, 2009;Birkmann, 2011;Birkmann et al, 2013, Okayo, Odera, andOmuterema, 2015;Islam et al, 2018;Lechowska, 2018;Wang et al, 2018). Some studies have focused on coastal zone municipalities in the Amazon region of Brazil (Szlafsztein, Sterr, and Lara, 2006;Szlafsztein and Sterr, 2007;Mansur et al, 2018), concentrating on risk perceptions and mapping and adaptive capacity with regard to vulnerability reduction (Andrade andSzlafsztein, 2015, 2018).…”

This paper investigates coping and adaptation strategies and institutional perceptions of hydrological risk at the local scale in Santarém, an Amazonian city in the state of Pará, Brazil. Methods and tools of analysis encompassed secondary data, field observations, and qualitative techniques (focus‐group discussions and in‐depth interviews). Stakeholders from affected neighbourhoods describe their means of coping with and adapting to flooding, focusing on purposefulness, type of initiative and investment, risk timing, temporal and spatial scope, and performance. The results comprise an inventory of 16 mostly structural measures. The perceptions of six institutions of general responses to flooding are presented as opinions on actions that reduce the effects of such events, individual strategies and collective community endeavours in at‐risk areas, and the activities of the public and private sectors to manage floods. Understanding of coping and adaptation strategies and knowledge of institutional flood risk perceptions can benefit the implementation of risk and disaster reduction policies and practices.

“…Exemplo de uso dessa metodologia pode ser observada em áreas rurais (SCHNEIDERBAUER et al, 2013), no contexto das mudanças climáticas (YOHE e TOL, 2002) e de desastres naturais (ANDRADE e SZLAFSZTEIN, 2018). Na Amazônia estudos sobre desastres possuem maior ênfase na adaptação (MANSUR et al, 2018), na vulnerabilidade (ANDRADE e SZLAFSZTEIN, 2018) e gestão de riscos (ESPIRITO SANTO e SZLAFSZTEIN, 2016; SZLAFSZTEIN, 2012).…”
