Detailed explanation-1: -Permeable surfaces (also known as porous or pervious surfaces) allow water to percolate into the soil to filter out pollutants and recharge the water table.
Detailed explanation-2: -Medium textured soils (fine sandy loam, silt loam and silty clay loam) have the highest available water capacity, while coarse soils (sand, loamy sand and sandy loam) have the lowest available water capacity.
Detailed explanation-3: -Soils with smaller particles (silt and clay) have a larger surface area than those with larger sand particles, and a large surface area allows a soil to hold more water. In other words, a soil with a high percentage of silt and clay particles, which describes fine soil, has a higher water-holding capacity.
Detailed explanation-4: -Sandy soil is made of sand particles that are rough in texture. This prevents them from sticking tightly together. The space between sand particles is large for water to flow through it. Hence sandy soil drains faster than other types of soil.
