Objectives- A flood is a strangely high stage in river generally, the level at which overflows its banks inundates adjacent area. Flood occurs due to intense rainfall, dense population, industrialization, illegal settlement along riverbanks, bank erosion, tide, and urbanization, it causes harmful damage human beings properties. It can be taken care of by adopting risk measures. One measures dev...

Remote sensing technology serves as a powerful tool for analyzing geospatial characteristics of flood inundation events at various scales. However, the performance of remote sensing methods depends heavily on the flood characteristics and landscape settings. Difficulties might be encountered in mapping the extent of localized flooding with shallow water on riverine floodplain areas, where patch...

1. Chlorophyll a (Chl a) distribution across a 0.36 km restored floodplain (Cosumnes River, California) was analysed throughout the winter and spring flood season from January to June 2005. In addition, high temporal-resolution Chl a measurements were made in situ with field fluorometers in the floodplain and adjacent channel. 2. The primary objectives were to characterise suspended algal bioma...

The knowledge of flood-induced ground effects and flood-water dynamics is a crucial issue for hydro-geomorphic hazards assessment mapping, thus river management land use planning. This paper the related 1:15,000 map illustrate lower Orba River (NW Italy) its adjacent floodplain geomorphic response to 21–22 October 2019 extreme flood. was estimated be 500-years flood caused severe damage cultiva...

The flood-mediated connectivity between river channels and floodplains plays a fundamental role in flood hazard mapping and exerts profound ecological effects. The classic nearest neighbor search (NNS) fails to derive this connectivity because of spatial heterogeneity and continuity. We develop two novel data-driven connectivity-deriving approaches, namely, progressive nearest neighbor search (...

The purpose of the study is spatial analysis factors floodplain ecosystems and calculation rational use, through technical economic indicators efficiency haymaking. assessment forage base was obtained based on grass stand productivity hayfields in five key areas Ob River floodplain, soil properties, their qualitative characteristics necessary for understanding fertility ecosystems, which land d...

Floodplain roughness parameterization is one of the key elements of hydrodynamic modeling of river flow, which is directly linked to safety level estimation of lowland fluvial areas. Necessary input parameters are median grain size for unvegetated areas, vegetation density for forest and vegetation height and density for herbaceous vegetation. This paper presents a method for spatially distribu...

Efficient strategies for preparing communities to protect against, respond to, recover from, and mitigate flood hazard are often hampered by the lack of information about the position and extent of flood-prone areas. Hydrologic and hydraulic analyses allow to obtain detailed flood hazard maps, but are a computationally intensive exercise requiring a significant amount of input data, which are r...
