Best Management Practices as an Alternative Approach for Urban Flood Control

Infiltration basins also bring about significant improvements in water quality. Settling, adsorption, soil filtration, biological decomposition, and nutrient removal are facilitated by the soil matrix, plant roots, microorganisms, and ponding. Sediment, trace metals, nutrients, bacteria, and organic material are effectively removed from stormwater runoff. Thus, percolating water is purified before reaching the water table or stream network.
Microbial Bioavailability of Residual Organic Contaminants in Soils
Published in Donald L. Wise, Debra J. Trantolo, Remediation of Hazardous Waste Contaminated Soils, 2018
Soil matrix components are generally grouped into two main categories, inorganic and organic. The most commonly identified inorganic soil components are the mineral particles of clay, silt, sand, and gravel. These particles are distinguished by their size and constitute the bulk of the soil on a mass basis.4

Phytoremediation is a plant-based approach, which involves the use of plants to extract and remove elemental pollutants or lower their bioavailability in soil. Plants extend their root system into the soil matrix and establish rhizosphere ecosystem to absorb ionic compounds in the soil even at low concentrations through their root system, thereby reclaiming the polluted soil and maintaining its fertility. The phytoremediation strategies applicable for the remediation of contaminated soils are illustrated in Figure 4.

It can be visually observed that distribution and density of the roots are much higher after 4 months rather than those of 2 months at a constant depth. It can be found that by increasing the PA from 2 to 4 months, the porosity and the void ratio increased. This can be traced to increasing the number of roots of the plant, changing the fibre geometrical properties and roots distribution in all directions due to the presence of sub-roots and moisture content variations in the soil matrix.

The soil matrix is defined as a continuous natural independent body having three spatial and one temporal dimension, constituting a complex blend of minerals, organic matter (OM), air, and water that blankets the top layer of the earth aiding plant growth (Hartemink 2016). Research on soils has a long tradition which shows that the minerals and OM are important components in the soil matrix and play a key role in maintaining the soil fertility (Schultz 1989).
