Flood is a natural disaster that frequently happens and causes many material immaterial losses. During flooding, the suspended sediment carried along by streamflow. The amount of transported varies depends on anthropogenic factors. Limited studies have been conducted regarding relationship between peak flood volume its content. Therefore, study with purpose to understand rainfall characteristic...

[1] Hydrographs are an enticing focus for hydrologic research: they are readily available hydrological data that integrate the variety of terrestrial runoff generation processes and upstream routing. Notwithstanding, new techniques to glean information from the hydrograph are lacking. After early approaches of graphically separating streamflow components, hydrograph separations in the past two ...

Abstract Spatial modelling of flood-prone areas will provide maximum results if it is supported by the accuracy data acquired, mainly related to elevation or area’s topography. generated from accurate topographic can estimate river’s carrying capacity. This study built a spatial model using aerial, terrestrial, and hydrographic surveys. Aerial surveys were conducted UAV corrected terrestrial su...

Local scour holes are erosional bed structures that related to different scientific disciplines in Earth science and hydraulic engineering. scouring at naturally placed boulders is ubiquitous, but many competing factors make it difficult isolate the effects of a given variable. This especially true for local natural instream obstacles exposed unsteady flow conditions course flood hydrograph exp...

The July 2020 debris flow in Japan caused enormous damage, and briefing sessions on disaster prevention have prompted demands for detailed explanations predictions of such phenomena high-risk areas. It is necessary to obtain four-dimensional risk information, which considers temporal changes risk, rather than limiting the analysis conventionally static information. In this study, we developed a...

The calculation of base flow rates in rivers is complex since hydrogeological and hydrological studies should be performed. estimation storm hydrograph associated to various return periods even more challenging compared other events. This research provides a novel methodology compute gaged for extreme events based on statistical correlations daily flows. current does not require aquifers analys...
