The primary objective of this study was to examine the quality volunteered geographic information (VGI) data for flood mapping Hurricane Harvey. As a crowdsourcing platform, U-Flood project mapped flooded streets in Houston metro area. This research examines following: (1) If there are any significant differences water depth (WD) among hydraulic and hydrologic (H&H) model, Federal Emergency...

Natural floodplains play an essential role in the processing and decomposition of organic matter and in the self-purification ability of rivers, largely due to the activity of bacteria. Knowledge about the composition of bacterial communities and its impact on organic-matter cycling is crucial for the understanding of ecological processes in river-floodplain systems. Particle-associated and fre...

The objective of this study was to examine the impact of summer throughfall on the growth of trees, at upland and floodplain locations, in the vicinity of Fairbanks, Alaska. Corrugated clear plastic covers were installed under the canopy of floodplain balsam poplar/white spruce stands and upland hardwood/white spruce stands to control soil moisture recharge as a result of summer precipitation. ...

The Upper Paraná River floodplain is the last lotic stretch of an ecosystem seriously threatened given that circa 50% of the original ecosystem has been converted into reservoirs. To assess the recreational value of the Upper Paraná River floodplain, 174 tourists were interviewed using the Willingness to Pay--WTP and Travel Cost--TC methods. The annual aggregated WTP attributed by tourists was ...

Accurately mapping soil organic carbon (SOC) is conducive to evaluating storage and quality. However, the high spatial heterogeneity of SOC caused by river-related factors agricultural management brings challenges digital in floodplain farmland. Moreover, current studies focus on non-linear relationship between covariates, but ignore effective range environmental variables SOC, which prevents r...

Lowland multiple-channel rivers are characterised by floodplain-corridor heterogeneity, high ecological and heritage value, can be in quasi-stable states. This holistic study of a surviving temperate zone example (Culm, UK) uses geomorphological mapping, 14C, direct sediment dating (OSL, fallout radionuclides), palaeoecology. reveals the evolution channel-floodplain system from an initial braid...

Purpose. To improve the existing classification of residential landscapes and its basis for analyzing structure modern urban landscape technical systems in river valleys Right Bank Ukraine. Methods. This study is based on anthropogenic landscapes, concepts geotechnical systems, as well materials their own field observations, which were carried out during 2008-2021 The main research methods used...

Abstract: This paper presents the methodology and procedure for flood risk assessment using GIS and flood inundation model (FIM) based on the “micro-zonation concept” in which an entire floodplain considered is divided into numerous unit areas (meshes or grids). In this study, Shinkawa-river floodplain around Nagoya City of Aichi Prefecture in Japan an urbanized lowland area, which was greatly ...
