PASSIVECOLLECTORSYSTEMS

LARGE SCALECOLLECTOR

SYSTEMStreamside Systems allows the energy of the stream to deliver the bedload sediment up the Collectors’ ramp and into multiple hoppers. The fluidized sediment is pumped to a dewatering site for beneficial reclamation of harvested sediments and the water is returned to the Collector in a semiclosed-loop scenario. This system is available in both Standard and High Capacity, but is fully scalable for most applications.

FOREBAYCOLLECTOR

The purpose of a Forebay Sediment Collector ™ is to capture transporting sediment during storm events, thus reducing maintenance on sediment retention ponds and waterways. This unit consists of a Sediment Collector ™ atop a concrete collection tank. The Forebay Collector can be placed in areas where excessive bedload sediment is present, causing continual maintenance. The collection tank can be cleaned out through a manhole by vacuum truck or pumped out using a submersible sand pump.

Streamside Systems’ patented Sediment Collectors ™ represent a new, innovative technology, using simple physical principles to capture targeted sizes of bedload sediments. Passive Collectors allow the energy of the stream to move bedload sediment up the Collector’s ramp and into a hopper. As the sediment fills the hoppers, it is pumped to a dewatering or disposal site. The Collectors are passive, non-invasive, and operation will not increase instream turbidity. Large Collectors are effective grade-control structures, and will not cause headcutting when properly installed. Optional closed water systems are available; to prevent any consumptive water loss from the stream; to prevent debris impingement or blockage of the hopper screen; and to prevent entrainment of any fish larvae, macroin-vertebrates, or other biota.

Colorado State University

Colorado State University performed a flume test on our Collector technology, The results: 99%+ effective in collecting sediment >.25mm.

BEDLOAD MONITORINGCOLLECTOR

Streamside Systems Bedload Monitoring Collector ™ can be used to develop watershed sediment budgets for fine bedload sediments, to develop Total Maximum Daily Loads (TMDL) specially for bedload fines, and to monitor bedload transport rates through the watershed (to identify source areas or to monitor TMDL permit violations). Systems can be equipped with automated montoring technology.

Two-foot wide Collector is portable, and easily installed and moved by one person. Stream width monitored (24 inches) is much larger than that covered with alternative samplers, to reduce spatial variability.

The Collector captures true bedload, as opposed to net samplers which are biased by collection of suspended sediments and debris.

Out-of-stream sample sorting, and sample retention only when needed. Sediment transport can be related to stream stage and/or time of day. Samples can be collected discreetly, or can be pooled or composited.

Long-term sampling potential (hours to days or weeks, versus 30 to 60 seconds for Helley-Smith); this greatly reduces temporal variability.

Convenience of unattended sampling. Increased safety because personnel need not enter the stream during flood conditions, and are not limited by bridge access.

Using wing-walls, or a Collector located in a flume, you can collect and measure 100% of bedload in small streams.

In larger streams, you can emplace multiple portable units on a cross section, or use a single unit to collect samples along a cross-section. To eliminate all temporal and spatial variability (i.e., complete cross section monitoring), we can provide site-specific Collector designs for permanent installations, to monitor total bedload transport on a con-tinuous basis, for months or years.

CONTRACTORCOLLECTOR

SYSTEMStreamside Systems’ Contractor Collector ™ is an equipment pack-age for contractors that can be used on a variety of construction sites as a Best Management Practice (BMP). The system is designed to eliminate downstream sediment impacts from bedload transport during in-stream construction projects. It can be used to control bed-load sediment transport from disturbed sites and to prevent impacts of bed sediments from disturbed sites to downstream aquatic habi-tats or biota. Multiple Collectors can be installed for large-scale streams or rivers.

4’ Wing Walls

3” Trash Pump with Honda Engine

(2) 3” x 50’ Discharge Hose

Optional Electronic Control for Pump

Optional Drop Box Filter

A Drop Box Filter is a semi-portable filtering device that removes sand and silts from the output of Collectors. The sand and silt outflow from the units is piped into the filter input, then it enters the upper chamber, which spreads out the mixture across the filters face. As the water and sediment drops down the face of the filter it collides with the wedge wire compo-nents on the screen, forcing the greater than .01 in diameter sand forward and allowing the water and smaller fines to penetrate the screen, by the time the bottom is reached all the water has been removed and the sand is pushed off the lower ledge on to the sand pile. The water is returned to

A Drop Box Filter is a semi-portable filtering device that dewaters the sand/silt slurry from the output of Collectors. The Collector discharge is piped into the Drop Box Filter input where it enters the upper chamber, which spreads the mixture across the filters wedge wire screen. As the water and sediment drops down the face of the filter it collides with the wedge wire components on the screen, forcing the greater than .01 in diameter sand forward and allowing the water and smaller fines to penetrate the screen. The water is returned to the stream via the drainpipe.
