Moreover, several studies [11, 12, 13] noticed that both water and sediment discharge
of several world' rivers have shown progressive decrease during the last 50 years, which is more primarily due to reservoir construction, water abstraction, and soil conservation.
However, these methods determine only an average flow velocity and the sediment discharge
in the floodplain as a whole.
The recent sediment cover on the Lisbon shelf is largely determined by sediment discharge
from the Tagus (Tejo) River, a major river draining an area of more than 80 000 [km.
The maximum sediment discharge
for BT usually occurred ~12 min after the start of the experiment, during which 16 mm of rain was applied to the plots, whereas the sediment discharge
in the ST and GT plots peaked 18-20min later (Fig.
Internal and external experts pronounced the water and sediment discharge
as nontoxic and biodegradable.
Related to the liquid debit, maximal value of sediment discharge
Similarly the exponential curve line have been developed on the water flow and sediment discharge
data, because the exponential curve lines are used when the data rise or fall.
Usually sediment discharge
into Sefidrud River starts in October causing reduction of DO in all stations.
Six appendices are included, containing descriptions of rock scour, riprap design, sediment transport scaling for physical models, methods for estimating sediment discharge
, a glossary, and conversion of units.
Consequently, this is also the peak sediment discharge
To place the estimate of total sediment trapped in context, the sediment discharge
record from the watershed was summarized.
Infrequent large storms can produce large quantities of stream flow and sediment discharge
, but some of the flow occurs on the floodplain adjacent to the channel.
