LISST-StreamSide

 Sequoia's LISST-StreamSide test installation


Behind Sequoia's office in Bellevue,WA runs a small stream. We use this for testing the LISST-StreamSide.



 

The LISST-StreamSide is enclosed in a small cabinet.  Note the holes in the bottom for power and communication cables to and from the LISST-Pump, as well as drains for turbid water.


 

In the cabinet there is room for the freshwater source, used for cleaning and automatic zscat.  The LISST-StreamSide is at the bottom, together with the battery powering both the LISST-Pump and the LISST-StreamSide.


 

The LISST-Pump is submerged in the stream.


 
 
During rain storms the water level - and sediment concentration - goes up quite significantly.  Note that the pump box is more submerged and less visible than on the picture above.
 
 

The top plot shows the variability in concentration (µl l-1) and rainfall (in hr-1). Note peak in sediment concentration lagging peak in rainfall.
The bottom plot shows the variability in mean size (µm) and rainfall (in hr-1). Sediment size increases after the 2 rainfall peaks towards the end of the measurement period.
