“…This clogging decreases the porosity/permeability of the paving surface and hence the infiltration rate of a system. The degree that particle deposition onto pavement surfaces impacts on the performance of a system depends on the particle size distribution of the material and the pore structure or permeability of the system [14]. Street tree litter can also block permeable pavements.…”

Permeable interlocking concrete pavements (PICP) are specifically designed to remove sediment and other pollutants from stormwater runoff. Over time, this can lead to clogging of the PICP system. Previous research has shown that much of the clogging occurs on the bedding aggregate directly below the paving joints, while the remainder of the aggregate is unaffected. This paper describes a proof of concept study to delay the effects of clogging by making more efficient use of the bedding aggregate used in PICP systems. Lateral drainage slots were cut into the underside of PICP blocks to allow sediment-laden stormwater to access, and be filtered by, a greater surface area of bedding aggregate. Eight different slot designs were trialed in the study to determine which of the slot designs made the most efficient use of the bedding aggregate to filter the sediment from the stormwater. The study results demonstrated that the eight drainage slot designs deposited between 25% and 366% more sediment (by weight) beneath the pavers than the control pavement. The results of the study suggest that PICP systems with drainage slots cast into their bases would take much longer to clog than unmodified pavers, thereby proving the concept of this study.

“…With time and rainfall, materials will accumulate on the surface and in the joints of any type of permeable surface (R. Brown & Borst, 2013;Deo et al, 2010;Haselbach et al, 2006;Siriwardene et al, 2007). ICPI suggests that using a joint filling material will limit the surface clogging to the top 20-25 mm layer of the surface and would avoid the progression of clogging to deeper layer and the storage gallery.…”

DEDICATIONI dedicate my dissertation to my family and many friends. A special feeling of gratitude to my loving parents, whose words of encouragement and push got me this far. I also dedicate this dissertation to my wife, who stood by me, and I will always appreciate all her support throughout the process. This dissertation is an experimental study based on the findings of two Green Infrastructure (GI) stormwater control measures (SCMs) in Louisville, KY, which focused on the effects of the physical environment on the performance of GI. The GI installed in Louisville are suffering from extensive and rapid surface clogging and in order to optimize current and future GI, an understanding of the factors affecting the performance of the system is required. The study used the current literature to determine the surrounding factors and those of the permeable surface that had not been investigated enough, and used several configurations of GI to determine the effects of these variables on the surface clogging. iv ACKNOWLEDGMENTSThe module used to test these variables was a wooden flume, specifically designed and constructed from plywood so that the variables of the experiment could be incorporated in testing. The flume simulates a permeable pavement system with storage gallery and a bedding layer, and is paved with three different interlocking concrete pavements that provide gaps of three different sizes. The flume's longitudinal slope can be adjusted, and the permeable joint material can be included. The performance of the vi flume was measured using 7 time domain reflectometer (TDRs) instruments, manufactured by Campbell Scientific, which are located inside the storage gallery.After conducting 21 experiments with various configurations, the data was analyzed to reveal meaningful information. As expected, the experiments with permeable joint material show a clear separation for the sediment deposited on the surface, where empty gaps resulted in inorganics being deposited on the up gradient and organics on the down gradient.The Analysis of Variance (ANOVA) of the progression of clogging and progression of infiltration edge on the permeable surface showed that the increase of gap size from 6 mm to 9 mm did not result in a significant change, but the change to 12 mm gaps resulted in a significantly different rate for the progression of the first rate. The presence of #8 aggregate in the gaps resulted in significant changes in both rates and finally the change of slope from 1% to 3% created a significant change in the rate at which surface clogging progressed.vii

Infiltration facilities are applied increasingly as effective BMPs to the urban stormwater control. The important functions of the facilities are surface flow reduction, contaminants elimination and aquifer recharge resulting from filtration, retention and infiltration of stormwater by porous media. A major obstacle in operating infiltration facilities is clogging. Filters of porous media in the facility are clogged by deposition of sediment over time. Clogging reduces infiltration rate and lifespan of the facility. Clogging, thus, needs to be considered as one of the important design factors in constructing infiltration facilities. In this study, 3 clogging models were chosen to simulate clogging, which developed in different disciplines, environmental and geotechnical engineering. Since the models were developed initially for fine media, applicability to coarse media interested in this study needed to be examined. To examine the applicability of models, analytical procedures of models were thoroughly reviewed. Parametric studies were also conducted to determine appropriate input parameters. Finally, the models represented relatively appropriate applicability to estimate clogging developed in an artificial infiltration as well as a real infiltration testing conditions. Although further studies are still needed for considerable aspects in input parameters and equations, the models could be suggested as effective analytical tools to estimate clogging developed in infiltration facilities of urban stormwater.
