Field experiments on coarse-sediment displacement upstream of flood mitigation dams
This study deals with the transport behavior of the coarse-sediment at Masudagawa flood mitigation dam (FMD), Japan. Radio frequency identification system (RFID) was used to trace the displacement of the IC tagged particles following major flood events since June 2011. Through this, the relationship between recovery rate of the tagged particles and distribution of shear stress over the FMD bed ...
متن کاملبررسی عملکرد سدهای اصلاحی رسوب گیر خشکه چین در طول آبراهه‌ها در ترسیب مواد ریزدانه (مطالعه موردی: حوضه سد درودزن)
One of the simple methods for erosion control, flood mitigation and flood damage reduction in the streams is building the checkdams. The present study was carried out to evaluate the performance of checkdams, location across the streams in the retention of the fine sediments in Droudzan watershed in Southern Iran. For this purpose, a number of streams with many stabilized check dams which were ...

متن کاملOptimal Flood Mitigation over Flood Propagation Approximations
Globally, flooding is the most frequent among all natural disasters, commonly resulting in damage to infrastructure, economic catastrophe, and loss of life. Since the flow of water is influenced by the shape and height of topography, an effective mechanism for preventing and directing floods is to use structures that increase height, e.g., levees and sandbags. In this paper, we introduce the Op...
متن کاملSeismic Reflection: Upstream, Downstream, and on Earthen Dams and Dikes
High-resolution seismic reflection has been used successfully to characterize material and investigate a variety of problems associated with earthen dams and abutments. Limitations and challenges of seismic reflection when interrogating these structures and lithologies are nontrivial and require very critical thinking. Seismic reflection has proved an effective tool for mapping confining units ...
متن کاملQualitative and Quantitative Assessment of Check-dams Effectiveness for Flood Sediment Deposition (Case Study: Dam-tang Watershed, Darab)
One of the simple methods for erosion control, flood mitigation and flood damage reduction in the streams is building the check-dams. The present study was carried out to evaluate the performance of check-dams, location across the streams in the retention of the fine sediments in Dam-tang watershed in Darab Iran. For this purpose, two of streams with many stabilized check-dams which were more t...
