Compacted Urban Soils Effects on Infiltration and Bioretention Stormwater Control Designs
Prior research by Pitt (1987) examined runoff losses from paved and roofed surfaces in urban areas and showed significant losses at these surfaces during the small and moderate sized events of most interest for water quality evaluations. However, Pitt and Durrans (1995) also examined runoff and pavement seepage on highway pavements and found that very little surface runoff entered typical highw...
متن کاملCompacted Urban Soils and their Remediation
The effects of urbanization on soil structure can be extensive. Infiltration of rain water through soils can be greatly reduced, plus the benefits of infiltration and biofiltration devices can be severely jeopardized. Our research group (along with others), have been studying disturbed urban soils for several decades, both in the laboratory and in the field. The effects of compaction on infiltr...
متن کاملImproved or Unimproved Urban Areas Effect on Soil and Water Quality
Construction in urban areas usually results in compacted soil, which restricts plant growth and infiltration. Nutrients may be lost in storm runoff water and sediment. The purpose of this study was to determine if existing lawns benefit from aeration and surface compost additions without the negative impact of nutrient loss in runoff. Four sets of lawns were compared, with or without compost pl...
متن کاملRemediating Compacted Urban Soils with Tillage and Compost
Urban areas typically have a high degree of impervious surfaces— that is, roads, parking lots, rooftops, and other surfaces that impede the movement of water into the soil. In predevelopment areas with natural ground cover, over half of precipitation infiltrates the soil to replenish groundwater tables, and only a small amount (10%) remains as runoff into stormwater systems, rivers, and lakes. ...
متن کاملLead Speciation and In Vitro Bioaccessibility of Compost-Amended Urban Garden Soils.
In situ soil amendments can modify the Pb bioavailability by changing soil Pb speciation. Urban soils from three vegetable gardens containing different total Pb concentrations were used. The study evaluated how compost amendment and aging of soil-compost mixture in situ affected the following: (i) soil Pb speciation in the field and (ii) change of soil Pb speciation during an in vitro bioaccess...
