Effects of toe configuration on throughflow properties of rockfill dams [PDF]
, 2021 Rockfill dams must be equipped with defence mechanisms to counteract the destabilizing effects of throughflow forces under accidental leakage scenarios. A key component of the rockfill dam overtopping system is the rockfill dam toe, constructed in tandem

A three-dimensional elasto-plastic dynamic response procedure for concrete-faced rockfill dams
International Journal of Distributed Sensor Networks, 2018 Equivalent linear dynamic analysis is the primary method of analysis for concrete-faced rockfill dams during earthquake. However, this method cannot be directly used to estimate permanent deformation during earthquake, which is important to evaluate the ...

A simulation-optimization approach to determine optimum features of detention rockfill dams under flood condition [PDF]
مهندسی منابع آب, 2019 Detention rockfill dams are one of the structural methods that can control flood risks with no impermeable core or membrane. These dams decrease the maximum discharge of flood hydrograph and postpone the time of its occurrence reducing life and financial

Environmental DNA, Volume 8, Issue 5, September‐October 2026.Megadam regulation was associated with contrasting relative importance of abiotic and biotic predictors of diatom chlorophyll‐based resource use efficiency. Reservoir RUE was more strongly associated with phylogenetic diversity, network complexity, and stability, whereas downstream RUE was mainly associated with turbidity, temperature, and nutrient ...
