Abstract A correct understanding of the parameters and methods used in flood susceptibility mapping (FSM) is critical for identifying strengths limitations different approaches, as well developing methodologies. In this study, we examined scientific publications literature using WoS. Although number quite high, these varies, with a maximum 21 minimum 5 preferred. It was found that most commonly parameter has preference rate 97%, but there no common 100% studies. The determining include multi-criteria decision-making (MCDM) methods, physically based hydrological models, statistical various soft computing methods. use traditional MCDM already high among researchers, analysis have evolved over years from human judgments to on big data machine learning. reviewed studies, it observed learning, fuzzy logic, metaheuristic optimization algorithms, heuristic search which are been widely FSM recent years.

Flooding is a natural disaster that coexists with human beings and causes severe loss of life property worldwide. Although numerous studies for flood susceptibility modelling have been introduced, notable gap has the overlooked or reduced consideration uncertainty in accuracy produced maps. Challenges such as limited data, due to confidence bounds, overfitting problem are critical areas improving accurate models. We focus on mapping, mainly when there significant variation predictive relevance predictor factors. It also noted receiver operating characteristic (ROC) curve may not accurately depict sensitivity resulting map overfitting. Therefore, reducing was targeted increase improve processing time prediction. This study created spatial repository test models, containing data from historical flooding twelve topographic geo-environmental conditioning variables. Then, we applied random forest (RF) extreme gradient boosting (XGB) algorithms susceptibility, incorporating variable drop-off empirical loop function. The results showed function crucial method resolve model associated factors methods. approximately 8.42% 9.89% Marib City 9.93% 15.69% Shibam were highly vulnerable floods. Furthermore, this significantly contributes worldwide endeavors focused hazards linked disasters. approaches used can offer valuable insights strategies risks, particularly Yemen.

Abstract Annually, Kogi State in Nigeria experiences significant flooding events, leading to serious fatalities, the destruction of livelihoods, and damage vital infrastructure. This study presents a multi-faceted approach methodology generate state-wide flood risk map by analyzing both vulnerability hazard factors. Seven factors (drainage length, distance river, elevation, slope, rainfall, from confluence/dam area, geomorphology) (population density, female population, land cover, road hospitals, literacy rate, employment rate) were ranked weighted based on their contributions within state using Fuzzy Analytical Hierarchy Process (FAHP). From these, Flood Hazard Index (FHI), Vulnerability (FVI), Risk (FRI) derived. Results showed that Kabba, Idah, Olamabor, Kotonkar, southern part Ajaokuta LGAs exhibit high due dense populations, remoteness roads critical infrastructure, considerable distances healthcare facilities. Likewise, exhibiting very FHI occur along geographic zones bounded confluence Niger Benue rivers, specifically Lokoja Kogi, Bassa, Ibaji LGAs. Five classes—very low, moderate, high, FRI classes—occupy 26.82, 31.12, 22.07, 15.26, 4.71% respectively. Out 295 villages, 65 villages are spread across zone. The safest include Ankpa, Omala, Dekina, Ijumu, Mopa-Muro

Flood events have caused huge disasters with regard to human life and economic development, especially short-term flood that occurred in recent years. Gravity Recovery Climate Experiment (GRACE) satellites can directly detect the spatiotemporal characteristics of terrestrial water storage anomalies (TWSA), which play an important role capturing signals. However, monthly resolution GRACE-derived TWSA limits its application monitoring sub-monthly events. Therefore, this paper first reconstructs daily based on a statistical model near real-time precipitation temperature as input variables, then three indexes are developed reconstructed TWSA. Furthermore, these employed evaluate temporal spatial 2016 event Haihe River basin (HRB), including potential index (FPI), deficit (WSDI), combined climate deviation (CCDI). In contrast previous studies, TWSA-based is improved from scale scale, largely improves characterization monitoring. Results demonstrate (1) among ten kinds “Temperature-Precipitation” combinations, CN05.1-CN05.1 match well GRACE TWSA, publicly available datasets Nash-Sutcliffe efficiency coefficient (NSE) 0.96 0.52 ~ 0.81 respectively.
