Abstract Flash floods have long been common in Asian cities, with recent increases urbanization and extreme rainfall driving increasingly severe frequent events. Floods urban areas cause significant damage to infrastructure, communities the environment. Numerical modelling of flood inundation offers detailed information necessary for managing risk such contexts. This study presents a calibrated model using referenced photos, an assessment influence four events on water depth area Hanoi...
The hydrological stream flow modeling is applied by the Soil for Water Assessment Tool (SWAT) model in Xedone River basin, covering an area of 7,224.61 km2, southern part Laos. main objective this research to test performance and feasibility SWAT predicting river basin. calibrated validated two periods: 1993-2000 2001-2008, respectively, using SUFI-2 technique analysis. gives good results with high value R2 NSE larger than 0.70 daily simulation. Monthly simulation during calibration...
Floods are among the world's most devastating natural disasters, causing immense damage and accounting for a large number of deaths world-wide. Good flood management policies play an extremely important role in preventing floods. It is well known that China has more than 5000 years experience policy beginning with reign DaYu Gun. Although culturally related, Japanese developed differently from China. Under rapid development civil engineering technology, was achieved primarily through...
Precipitation, as a primary hydrological variable in the water cycle plays an important role modeling. The reliability of modeling is highly related to quality precipitation data. Accurate long-term gauged Mekong River Basin, however, limited. Therefore, main objective this study assess performances various gridded datasets rainfall-runoff and flood-inundation whole basin. Firstly, performance Rainfall-Runoff-Inundation (RRI) model basin was evaluated using rainfall. calibration (2000–2003)...
Apple cultivation is one of the most important sources livelihood in Indian side Himalayas. The present study focuses on apple orchards Himachal Pradesh, a state within Himalayan Mountains, major producers India. In study, it found that optimum growing conditions region have been consistently shifting and farmers are their to higher altitudes. For example, shifted 1500–2500 meters 2000s compared cultivated elevation 1200–1500 during 1980s. As 2014, apples being at an more than 3500 meters,...
Abstract This survey proposed a new methodology ‐ iGAEZ (improved GAEZ), developed based on the GAEZ (Global Agro‐Ecological Zones) model, capable of simulating crop yields global scale for wheat, potato, cassava, soybean, rice, sweet maize, green beans. determines optimum criteria parameter growth cycles to ensure best realistic yield combinations under comprehensive consideration climate and condition. Global‐scale were calculated using model period 1990‐1999. Through comparing simulated...
In order to promote pollutant monitoring and preservation of water resources, we evaluate the spatiotemporal trends in recent quality conditions Japanese rivers. Trend analysis is conducted on 92 major rivers Japan using available data recorded from 1992 2005 characteristics pollutants these are analyzed. Spatial temporal for six indicators Mann Kendall test, a non-parametric statistical method. The analyzed biochemical oxygen demand (BOD), chemical (COD), dissolved (DO), total nitrogen...
Abstract In combination with land use change, climate change is increasingly leading to extreme weather conditions and consequently novel hydrologic conditions. Rainfall Area intensity‐duration‐frequency ( IDF ) curves, commonly used tools for modeling hydrology managing flood risk can be assess response under rainfall We explore the influence of on designed over period 1976 2006 in Kamo River basin. Run‐off all six shapes higher than that use, but timing peak discharge occurs at roughly...
