“…There is an inconsistency in the estimation of flood risk, since damage assessment studies are undertaken less often than hazard assessments [10]. This may be due to a lack of data and an inadequate model for loss estimates.…”

“…Any natural disaster requires a fundamental quantification of loss based on a damage assessment. Direct damages are defined as any damage that results from direct contact between flood water and humans, property, or other things, while indirect damage is considered as any damage that results from direct damage after a specified length of time or distance [10]. According to D. Dutta et al, (2003), flood damage may be divided into two major categories: material and intangible.…”

Extreme rainfall variations generally result in either extreme precipitation accompanied by flood risk events. Globally, flooding has been a major worry, particularly in Malaysia. In recent years, the frequency and magnitude of floods have grown substantially. Severe precipitation has caused significant devastation to human life and property. Exposure, vulnerability, and risk analysis use inventories of elements-at-risk (EaR), also known as assets, to determine who and what is at risk. The recent occurrence that occurred in February and December 2022 were unprecedented and cause RM29.8 million of economic losses in Kelantan. Numerous problems that range from structural, social, environmental, economical to psychological impacts strike over the community in this flood prone area. Almost 230, 424 people and 54, 924 houses were directly impacted by this flood event. The primary objective is to determine the entire amount of a disaster’s effect on a nation and based on these findings, to develop an executable and sustainable Recovery Plan for mobilising financial and technical resources. The methodology and procedure for a full evaluation of damages, losses, and requirements, leading to the establishment of a Recovery Strategy. Assessment and Recovery Strategy produced during the PDNA is a necessity as it is a more thorough recovery planning, especially in the event of large-scale disasters. Mapping the impact of the flood catastrophe and gathering all information related to the communities to get back to their daily lives a comprehensive assessment is imperative. With these building back better is feasible for this exposed community. The PDNA analyses disaster consequences and implications. It uses analytical approaches, tools, and strategies for post-disaster evaluations and recovery planning to ensure comparability and uniformity. It provides complete picture of the post-disaster situations highlighting the various requirements and goals of different sectors, social groups, and sub-groups.

“…The distinction among the scales is evident in the extent of analysis and the data complexity required, as presented in Table 2. A macroscale assessment is conducted at the global or national level or based on the aggregation of cities such as municipalities and FDA classification based on data collection methods for model development is grouped under two approaches: the empirical approach and the synthetic approach [12,13,73]. The empirical approach estimates actual or potential damage to a building from an actual flood event.…”

Flood Damage Assessment: A Review of Microscale Methodologies for Residential Buildings

Flood damage assessment (FDA) is an essential tool for evaluating flood damage, vulnerability, and risk to civil systems such as residential buildings. The outcome of an FDA depends on the spatial limits of the study and the complexity of the data. For microscale FDA, a high level of detail is required to assess flood damage. This study reviewed the existing methodologies in microscale FDA based on empirical and synthetic data selection methods for model development. The merits and challenges of these approaches are discussed. This review also proposes an integrated step for assessing the stages of FDA. This study contributes to the literature by providing insights into the methodologies adopted, particularly on a microscale basis, which has not been comprehensively discussed in the previous reviews. The findings of this study reveal that univariate modeling of flood damage is nevertheless popular among researchers. New advanced approaches, such as advanced machine learning and 3D models, are yet to gain prominence when compared with the univariate modeling that has recorded a high success. This review concludes that there is a need to adopt a combined empirical–synthetic approach in the selection of data for developing damage models. Further research is required in the areas of multivariate modeling (advanced machine learning), 3D BIM-GIS modeling, 3D visualization of damages, and projection of probabilities in flood damage predictions to buildings. These are essential for performance flood-based building designs and for promoting building resilience to flood damage.

“…The average intrinsic growth rate of the Richards model of 0.055/day can be used as an early warning indicator [Burkhard et al, 2015;Forni et al, 2016], which indicates the potential for water abundance in the reservoir [Mushar et al, 2019]. The potential for flood disasters triggered by the abundance of water is becoming higher along with the shrinking capacity of the reservoir due to increased sedimentation.…”

“…The speed at which a reservoir reaches its water volume carrying capacity is important information in the sustainable reservoir management. The hydrological indicators that lead to the abundance or scarcity of water are the ecological data in dynamic modeling for early warning purposes [Burkhard et al, 2015;Forni et al, 2016] and for prediction [Mushar et al, 2019]. Mathematical modeling has the ability to predict based on historical data.…”

The rate of growth of the water volume in the reservoir varies with each charging season. The accuracy of the predictions is required in sustainable reservoir management. Its intrinsic growth rate as an ecological parameter plays a role in determining this speed. This study aimed to analyze the dynamics of water volume growth based on its intrinsic growth rate to assess the potential for hydrometeorology disasters. The population growth models proposed to be tested for suitability and goodness is the Verhulst, Richards, Comperzt, and modified Malthus model. Test suitability and model goodness were subjected to stages of verification, parameter estimation and model validation based on daily water volume data in the Gembong Reservoir, Pati, Indonesia for the period 2007-2020. A good model is determined based on the Mean Average Percentage Error (MAPE) criteria. The Richards model with b = 2 and r = 0.063/day had consistently low MAPE values during training and testing. This model was chosen as a new approach to understand the dynamics of water volume growth in a reservoir. The ecological implication of these dynamics of water volume growth is that reservoirs experience an abundance of water during the charging season. Reservoir normalization can be prioritized as a mitigation strategy for potential flood disasters.
