Egypt suffers from freshwater crisis, and the shortage is predicted to become severe by 2025. Egypt is exposed to flash floods, especially in Sinai governorate, causing rapid rises of water in a short amount of time and can trigger other catastrophic hazards associated with damage, danger to human life, properties and environment. Flash floods may be considered a source of water that can be explored to meet the water shortage problem. In this study, a composite flash floods vulnerability index based on an integrated hydro-climatic and physical vulnerability component was created. The composite index was based on eight parameters including rainfall distribution, elevation and slope, flow direction, streams, geomorphological features, soil type and land cover. The composite index was ranked into three categories: high, moderate and low. The index can help identify the weak and strong points to support the decision-making process concerned with water management as an essential prerequisite for Egypt sustainable development. The results revealed that the urban, vegetation cover, loamy sand, sand dunes, the low elevation and the flat areas are the most affected by the flash floods in EL-Arish City in Sinai governorate. 42% of Wadi El-Arish had low vulnerability, 45% moderate vulnerability and 13% high vulnerability.

“…Digital elevation models (DEMs) are popular for extracting topographic parameters. Elkhrachy (2015), Cao et al (2016) and Azmeri and Isa (2018) used digital elevation model in a GIS for flood mapping. DEMs are raster files with elevation data for each raster cell.…”

The tree canopy around Merapi Volcano, Yogyakarta, Indonesia, has a unique structure. The frequency of volcanic eruptions influences the uniqueness of the structure, as it is a response to volcanic ash and rainfall characteristics. This research was conducted on eight species that have different canopy structures. In contrast to the trees canopy that was not affected by eruptions, the tree canopy around the Volcano has more dynamic canopy surface characteristics during the recovery period. The redistribution of rainfall in the tree canopy was traced by calculating unit area discharge and droplets' probability in each canopy structure segment. The results of empirical throughfall calculation and throughfall direct observation were tested using ANOVA. Most of the throughfall occurs simultaneously under the canopy during rain with a depth of 3.5 -72.5 mm or intensity of 10 -20 mm/hour (observed = 58% and empirical = 57%). The existing range of rainfall intensity or rainfall depth shows that the process of redistribution of rainfall in the canopy has time constraints and canopy storage capacity constrain. The canopy surface characteristics have a more significant effect than the canopy structure on the redistribution of rainfall. The canopy surface serves as a sheet of rainfall concentration to the next section. The important canopy surface structure parameters to rainfall concentration are leaves characteristics, branches stiffness, and crown density. Knowledge of the tree canopy's rainfall flow distribution process will help manage conservation-based rehabilitation activities in areas prone to volcanic disasters.

“…Flood disasters will have an impact on social conditions, health status, deaths, and the economy of the community. Losses due to flooding include damage to houses which cause relatively high costs to recover damage, loss of crop yields, and uncertainty about the future directly or indirectly that will affect people's lives, and psychological conditions of the victims (Azmeri & Isa, 2018).…”

Background: Indonesia is one of the areas classified as disaster prone area, because every year has increased between 1,500-2,000 times and most are hydro-meteorological disasters such as floods. Efforts to reduce threat to flood disasters are to do prevention, mitigation, and preparedness. Objective: To identify and analyze the relationship between community attitudes and flood mitigation in the Welang watershed in the Karangketug Urban Village, Pasuruan City. Methods: This study used an analytic observational design with a cross-sectional approach. The population was 143 householders and the samples were 105 householders living in the river flood disaster-prone areas Welang RW. 01 / RT. 02-03 Karangketug Urban Village, Pasuruan City. The sampling method is purposive sampling. The Spearman rank correlation test was used for data analysis with a significant level (α) = 0.05. Results: The Spearman Rank test correlation indicates that there is a significant correlation between attitude and the mitigation of floods (p = 0.000 and r = 0.546). Conclusion: Personal factor such as attitude significantly correlate with community mitigation in the face of flood disasters in the Welang watershed in the Karangketug Urban Village, Pasuruan City.
