Macroinvertebrate community succession in the Three-Gorges Reservoir ten years after impoundment

Influence of turbid flood water release on sediment deposition and phosphorus distribution in the bed sediment of the Three Gorges Reservoir, China

“…For TP, the upper 0-10 cm sediment layer typically contains much higher levels of 1463.47 mg/kg than 853.83 mg/kg in the lower 10-20 cm sediment layers, and the most heavily contaminated sediment layer is the top 0-5 cm, where P is mobile and easily released to the overlying water column (Wu et al, 2011). In contrast to lakes, in the TGR, low turbidity water is stored in the dry season and water with high suspended sediment load is discharged in the wet season to both prevent sediment deposition (Li et al, 2015a) and ensure continued sediment supply to the river downstream. The hydrodynamic process in the flood season may flush the reservoir bed and transport a part of the bed sediment (BS) and SS downstream through the TGD.…”

Aplicación de un índice multimétrico basado en macroinvertebrados bentónicos en un embalse del norte argentino

“…₄₉ filtradores y también depredadores. Son uno de los grupos que muestran alta abundancia en los embalses, independientemente del nivel de disturbio antropogénico (Gomes et al 2018), la profundidad (Magbanua et al 2015) y el régimen hidrológico (Li et al 2015). Por esta razón, la baja abundancia de quironómidos registrada en este estudio puede deberse a las condiciones de extrema degradación ambiental del embalse.…”
