Abstract. Flooding is one of the most disruptive natural disasters, causing substantial loss life and property damage. Coastal cities in Asia face floods almost every year due to monsoon influences. Early notification flooding events enables governments implement focused preventive actions. Specifically, short-term forecasts can buy time for evacuation emergency rescue, giving flood victims tim...

Soil waterlogging is an environmental limitation that promoted by changes in rainfall patterns and negatively affects plant physiology, growth, development, coffee production, exports Colombia. The objective of this research was to evaluate responses water status, chlorophyll fluorescence parameters for plants under different conditions. evaluations were carried out on six-month-old “Cenicafé 1...

Measurements of methane (CH(4)) and nitrous oxide (N(2)O) fluxes have been extensively taken following rice seedlings transplanted into paddy fields, while little is known about CH(4) and N(2)O fluxes from rice seedling nurseries. Fluxes of CH(4) and N(2)O were simultaneously measured in rice seedling nurseries under the water regimes of continuous flooding and moist irrigation without waterlog...

The waterlogging tolerance and the physiological responses to this stress were tested in seedlings of Fraxinus angustifolia, an ash tree inhabiting riparian forests, and two provenances of the closely related Fraxinus excelsior, one derived from a riparian forest (FER) and one from a mountainous region (FEM). Besides visible damage, physiological parameters reflecting adaptations of plants to w...

Due to changing climate, flooding (waterlogged soils and submergence) becomes a major problem in agriculture and crop production. In the present study, the effect of waterlogging was investigated on peroxidases of maize (Zea mays L.) leaves. The plants showed typical adaptations to flooding stress, i.e., alterations in chlorophyll a/b ratios and increased basal shoot diameter. Seven peroxidase ...

This study proposes a solution to prevent urban waterlogging, challenging environmental issue, by integrating waterlogging prediction and drainage optimization schemes based on cellular automaton multi-objective theories. An model for uncertain flow was constructed considering surface fragmentation space complexity. For dynamic simulation, outputs of water depth flooded areas were projected wit...

In recent years, the frequency of extreme weather has increased, and urban waterlogging caused by sudden rainfall occurred from time to time. With development urbanization, a large amount land been developed proportion impervious area intensifying risk waterlogging. How use available meteorological data for accurate prediction early warning hazards become key issue in field disaster prevention ...

Introduction Waterlogging is a major stress that severely affects onion cultivation worldwide, and developing stress-tolerant varieties could be valuable measure for overcoming its adverse effects. Gathering information regarding the molecular mechanisms gene expression patterns of waterlogging-tolerant sensitive genotypes an effective method improving tolerance in onions. To date, waterlogging...

Superstandard conditions refer to extreme rainfall and river flooding that exceed the flood control system or works. In order explore influence of superstandard on urban waterlogging, based MIKE FLOOD platform, this paper takes downtown area Zhoukou as research object, it conducts waterlogging simulation in under once 20 years 50 combined with ultra-high water level river. The results inundatio...

Against the background of global warming, agricultural meteorological disasters such as waterlogging frequently occur, significantly restricting winter wheat yield and quality formation. Studying changing trend characteristics is beneficial to stabilizing yield. We collected data China’s main production areas in last 20 years explore impact different growth stages on production. The results sho...
