                                    Citation: MALONE, R.W., BONTA, J.V., LIGHTELL, D.R. A LOW-COST COMPOSITE WATER SAMPLER FOR DRIP AND STREAM FLOW. ASAE ANNUAL INTERNATIONAL MEETING. 2002. Paper No. 022148.Interpretive Summary:
                                Technical Abstract: The collection of flow proportional samples when flow rates range from slow drip flow to slow stream flow is important in hydrology.  A slot sampler was modified for this purpose and its field/lab performance was monitored.  The major design criteria include:  function for flow rates between 0.5 and 200 mL/min; minimize sampler catch variance between trials; allow total flow volume estimate from sampler catch volume; compact in size; useful in remote conditions; low cost; low maintenance; and easily constructed from readily obtainable materials.  The designed sampler collected approximately 2.0% of flow with a sampler catch coefficient of variation between trials of less than 5%.  This allows total flow rate to be estimated and flow proportional samples for water quality analysis to be collected.
