Antagonistic microorganisms against Rhizoctonia solani were isolated and their antifungal activities were investigated. Two hundred sixteen bacterial isolates were isolated from various soil samples and 19 isolates were found to antagonize the selected plant pathogenic fungi with varying degrees. Among them, isolate C9 was selected as an antagonistic microorganism with potential for use in further studies. Treatment with the selected isolate C9 resulted in significantly reduced incidence of stem

Streptomyces albidoflavus C247 was isolated from the soil of the Gyeongsan golf course in Korea. Physiological, biochemical and 16S rDNA gene sequence analysis strongly suggested that the isolate belonged to Streptomyces albidoflavus. Preliminary screening revealed that the isolate was active against fungi and bacteria. Self-directing optimization was employed to determine the best combination of parameters such as carbon and nitrogen source, pH and temperature. Nutritional and culture condition

In recent years, rainfall-induced waterlogging has become a common hazard in the highly urbanized coastal city of Chattogram, Bangladesh, resulting in a high magnitude of property damage and economic loss. Therefore, the primary objective of this research was to prepare a waterlogging inventory map and understand the spatial variations of the risk by means of hazard intensity, exposure, and vulnerability of waterlogging. In this research, the inventory map and factors influencing waterlogging ha

Arsenic (As) pollution is one of the major threats to public health in Bangladesh, where daily intake of As per person exceeds the World Health Organization recommended level. Plants can assimilate significant quantities of As on a daily basis. Consumption of rice contaminated with As from soil and irrigation water can elevate the daily As intake in humans. In this study, we aimed to identify indigenous As-tolerant bacteria with the ability to use different carbon and nitrogen sources to enhance

In this study, 42 years of tidal records and landfall TC best tracks in Japan were used to demonstrate that TC pre-landfall forward speed is significantly correlated with maximum storm surge height. Coastal morphology was the determining factor for the correlation between storm surge and TC forward speed. Fast-moving TCs tended to amplify the storm surge along open coastlines (Pearson correlation coefficient, R = 0.62), but reduce it in semi-enclosed bays (R = −0.52). The negative correlation co

This study presents a new storm surge hazard potential index (SSHPI) for estimating tropical cyclone (TC) induced peak surge levels at a coast. The SSHPI incorporates parameters that are often readily available at real-time: intensity in 10-min maximum wind speed, radius of 50-kt wind, translation speed, coastal geometry, and bathymetry information. The inclusion of translation speed and coastal geometry information lead to improvements of the SSHPI to other existing surge indices. A retrospecti

Based on our preliminary survey, which began 13 days after the landfall of Typhoon Lan, this paper assesses the situation along the coastline of Kanagawa, Chiba, and Tokyo, with a particular emphasis on the damage to coastal and port structures. It also discusses the research necessary to mitigate the future coastal flooding risk in and around Tokyo Bay. Storm-surge height, wave run-up height, coastal erosion, and infrastructure damage in various places are given. Extensive scouring was observed

This study investigated tidal records and landfall tropical cyclone (TC) best tracks from 1980 to 2019 to determine changes in storm surge heights in coastal regions of Central Japan, including Tokyo. The results indicate that annual mean storm surge heights have increased in the last 20 years (2000–2019) compared with those in 1980–1999, and that these changes are noteworthy, particularly in Tokyo Bay. The TC wind intensity and size during landfall have become stronger and larger, respectively,

Abstract Ensemble forecasting is a promising tool to aid in making informed decisions against risks of coastal storm surges. Although tropical cyclone (TC) ensemble forecasts are commonly used in operational numerical weather prediction systems, their potential for disaster prediction has not been maximized. Here we present a novel, efficient, and practical method to utilize a large ensemble forecast of 1,000 members to analyze storm surge scenarios toward effective decision making such as evacu

Abstract Variability in storminess, storm surge, and mean sea level (MSL) can substantially alter coastal hazards associated with extreme sea levels (ESLs). However, the detection and attribution of the past changes in tropical cyclone (TC) activity and associated storm surges are hampered by the inhomogeneous TC records. In this study, we investigate spatiotemporal changes in storm surge levels in Japan from 1980 to 2019, a period when observational platforms including tide gauges and storm rec

Abstract Tropical cyclones (TCs) have historically had far-reaching impacts on livelihoods and vulnerable coastal communities in Bangladesh. Characterizing and understanding the complex and multifaceted nature of TCs is essential for identifying gaps and opportunities to enhance the effectiveness of disaster management practices. This study advances our understanding of TC dynamics in Bangladesh by conducting an integrated analysis of disaster statistics, preparedness measures, and meteorologica
