A Performance-Based Modified RRV Framework for Evaluating the Dynamic Operation of Urban Flood Control Storage Systems

Hosoo Lee, Gwangmin Ok, Bogyeong Choi, Seogyeong Lee et autres

Urban flood control basins without forced drainage operate as one-shot systems: they must perform within a single event and cannot empty themselves until it ends. The timing of gate closure is therefore decisive—closing early wastes storage, whereas closing late lets stored water …

Cross-Tributary Water Mass Signals and Seasonal Stratification Dynamics in a River-Type Reservoir

Soobin Yoon, ChangHyun Lee, Young‐Do Kim

Seasonal stratification in river type reservoirs controls vertical water quality structure, but it is difficult to assess where only routine monitoring data are available. This is particularly relevant to Paldang Reservoir, where multiple tributaries, short residence time, rainfall, and dam operation interact …

Environmental Safety Assessment of Riverfront Spaces Under Erosion–Deposition Dynamics and Vegetation Variability

Sangung Lee, Jong‐Min Kim, Young‐Do Kim

Urban river floodplains function not only as zones for flood regulation and ecological buffering but have increasingly been utilized as multifunctional spaces that support leisure, waterfront, and cultural activities. However, overlapping hydraulic and geomorphic factors such as channel meandering, vegetation distribution, and …

Application of Hydraulic Safety Evaluation Indices to Waterfront Facilities in Floodplains

Jong‐Min Kim, Tae Geom Ku, Sangung Lee, Gwangmin Ok et autres

Climate change has intensified torrential rainfall and floods, causing frequent floodplain inundation with erosion and deposition. Large-scale waterfront facilities such as park golf courses are highly vulnerable, requiring systematic hydraulic safety evaluation. We simulated a recent flood in the Musim Stream using …

Development and application of a watershed-based environmental drought index reflecting water cycle characteristics

Jaeyeon Lim, Sangung Lee, Bu Geon Jo, Joo‐Heon Lee et autres

Droughts driven by climate change increasingly affect aquatic ecosystems by deteriorating water quality. However, conventional drought indices primarily focus on water quantity, limiting their ability to capture environmental impacts. To address this gap, this study develops the Water Quality Environmental Drought Index …

Adaptive electronics for photovoltaic, photoluminescent and photometric methods in power harvesting for wireless wearable sensors

Chanho Park, Do Yun Park, Haohui Zhang, Da Som Yang et autres

The increasing demand for continuous, comprehensive physiological information captured by skin-interfaced wireless sensors is hindered by their relatively high-power consumption and the associated patient discomfort that can follow from the use of high capacity batteries. This paper presents an adaptive electronics platform …
