“…annual flow of Abukuma is 112 m 3 /s, and the average annual rainfall is 1100 mm in the plains and 1200-1500 mm in the mountains [30]. Paddy field covers 12.4% of the river's watershed areas, and most of these fields are close to the main river channel, which indicates their fair potential to store rainwater and contribute to discharge reduction.…”

Impact of Paddy Field Reservoirs on Flood Management in a Large River Basin of Japan

et al. 2023

The flood retention capacity of paddy fields is well-recognized in Japan, and all the existing flood control practices via paddy field management achieve reductions in peak flood discharge. However, the previous studies have not assessed the flood management potential of paddy fields in a large river basin with average paddy coverage, and the existing hydrological models are not quite suitable for simulating river discharge from closed-drainage paddy reservoir storage. We herein attempt to improve the watershed-scale version of global hydrological model H08 to simulate a reduction in the peak discharge from paddy reservoirs in the Abukuma River basin of Japan. The NSE and R2 index showed fair reliability of the H08 model during the calibration and validation stages. The simulated results from the improved model show 11% and 6% peak reductions in high paddy coverage areas for a normal year (2018) and a major typhoon year (2019), respectively. The peak-reduction percentage increased with decreasing rainfall, depending on the overflow from the paddy reservoirs. The results indicate that the paddy reservoir is not highly effective in a large river with less than 20% paddy coverage, but the peak discharge reduction capacity shows that paddy reservoirs can make some contribution when used in combination with dam operation.

“…According to Prasetiya (2016), around 78% of the participants were able to tackle psychological difficulties more readily after a catastrophe as a result of psychological first aid training. Semlitz et al (Konami et al 2021) determined that following a training, participants had a significant increase in their ability to assess the needs of people affected by a disaster. They were able to distinguish normal stress reactions from mental health problems, avoid causing harm while assisting people affected by the disaster, and determine what to do next (Inoue et al 2019).…”

Highlight : Disasters impact a large number of people, including nurses who are deployed in the disaster relief. Culturally sensitive psychological first aid sessions, post-assignment in crisis situations monitoring, and grit have implications in pushing the nurses to overcome their trauma and obstacles. Government policies are also important in helping nurses to heal after deployment in disaster relief. Abstract : Disasters are defined as catastrophic occurrences that impact a large number of people quickly and with an abrupt onset. On average, one natural disaster is reported globally each day. However, the impact of a traumatic occurrence on an individual may be compared to a rock colliding with the surface of a water body. Systematic searches were conducted in Cochrane, Google Scholar, PubMed, Scopus, Embase, and Web of Science databases. The following keywords were used to perform a literature search: "nurse," "healing," and "natural catastrophes". As a result of reviewing 362 abstracts and titles, ten were determined to meet the study goals. The research methods in four of the ten literatures were qualitative, five quantitative, and one was a blend of both. Generally, culturally appropriate psychological first aid sessions, post-natural disaster assignment monitoring, and grit push people to overcome obstacles and accomplish achievements over time. Nurses who have been deployed to natural catastrophes must heal and need time to rest physically and mentally. This study aimed to find out the implications of culturally sensitive psychological first aid sessions, post-assignment in crisis situations monitoring, and grit in pushing individuals to overcome obstacles and achieve success over time; and how the government policies relate to trauma recovery.

“…Local urban flooding is a growing phenomenon in urban areas [1,2]. Although these types of floods cover only part of the catchment, their occurrence often results in the loss of property (both public and private), loss of employment and interruption of transport in trade [3,4]. Between 1995 and 2015, floods caused more than $662 billion in losses to the global economy, affected nearly 2.3 billion people worldwide and killed around 157,000 [5].…”

Assessment of the Feasibility of Implementing a Flash Flood Early Warning System in a Small Catchment Area

2023

The occurrence of flash floods is an increasingly common phenomenon. In many parts of the world, it is associated with an increase in the intensity of rainfall. Reducing the financial and social losses caused by the occurrence of local urban floods is possible through the use of hydrodynamic modeling and real-time flood forecasting. The purpose of this study is to assess the ability of the modeling technique to simulate the flow in a small catchment area and to determine the time remaining to reach the set warning and danger levels. SWMM 5.2 and QuantumGIS software were used in the study. The analysis showed that for the considered catchment area with a short length of the main stream (1612 m), the time possible for implementing countermeasures and evacuating the population is 70 to 120 min. The study also confirmed that short-term rainfall requires less depth to reach high stormwater elevations than long-term rainfall. In addition, a relationship was noted between the preceding rainfall and the height of stormwater and the forecast time. There was an unfavorable reduction in forecasting time as the depth of rainfall increased and its duration shortened. In the case of the analyzed catchment, the maximum elevation of stormwater (Esw,max) is generated by rainfall that is characterized by the highest intensity in the final phase of their duration. Similarly, the longest forecast time (tf) for the maximum stormwater elevation is caused by rainfall, which is characterized by the highest intensity in its final phase. The results of the study can significantly assist local governments when developing a catchment management plan and when trying to implement practices to minimize the negative effects of flash floods.
