A runoff water monitoring system for sampling sheet-flow from a generally flat surface having an edge comprises an elongated recess contiguous to the edge and depending below the generally flat surface. An insert in the recess has an upper end and an open frame plate member. A grate member is secured to the open frame and has a downwardly depending sample receptacle attachment sleeve and a grate plate having a predetermined number of sheet-flow metering apertures therein. A sample collection receptacle is releasably secured on the attachment sleeve to receive water flowing through the sheet-flow metering apertures. The sheet-flow metering apertures are preferably rectangular and have a rounded leading or upstream edge and square side and back edges. The sample receptacle over the attachment sleeve which has an endless groove in the sleeve and an endless elastic member is seated in the groove over the open end of the sample receptacle. The sample receptacle attachment sleeve includes an internal baffle for trapping floating pollutants. The sample receptacle has an indicia space to write collection data and a tongue-and-groove type seal spaced a predetermined distance below the mouth of the sample receptacle.
A runoff water monitoring system for sampling sheet-flow from a generally flat surface having an edge and an elongated recess contiguous to said edge and depending below said generally flat surface, said recess being elongated in a direction transverse to direction of sheet-flow, comprising:
In a sheet-flow runoff water monitoring device, the improvement comprising:
A collection receptacle for a runoff water monitoring system wherein metered runoff water is collected for analysis, said collection receptacle being flexible plastic and having a pair of side walls sealed to each other, an open top, and a tongue and groove press seal between said pair of side walls and located a predetermined distance below said open top.
A passive, simple to operate sheet-flow water quality monitoring device that can be easily configured to capture desired runoff volumes that are representative of the entire water column and sample area, and captures sheet-flow at a rate independent of runoff depth, comprising:
A method of sampling sheet-flow water runoff of a roadway surface having an edge comprising
A runoff water monitoring system for sampling sheet-flow from a generally flat surface having an edge and a recess contiguous to said edge and depending below said generally flat surface comprising a grate having a predetermined number of sheet-flow metering apertures therein, each of said sheet-flow metering apertures having a leading edge, said leading edge being shaped to enhance the capture of runoff water through said metering aperture, and a sample collection receptacle mounted in said recess and below said grate to receive water flowing through the sheet-flow metering apertures.
