Retention is a controlled flow where the system is not over loaded during a heavy rain storm.
The storm water is allowed to accumulate to a safe level (bearing weight) and slowly enters the leader lines.
Clay particles are the smallest and have the highest water retention capacity but drain poorly. Silt particles are medium-sized and have good water retention and drainage. Sand particles are the largest and have good drainage but low water retention.
Silty soil is best for water retention because it has fine particles that can hold onto water well. Clay soil also has high water retention capabilities, but it can become compacted and slow down drainage. Mixing organic matter into sandy soil can also improve water retention.
Soil texture plays a key role in determining the amount of air and water held in soil. Coarse-textured soils like sandy soils have larger pore spaces, allowing for good drainage but lower water retention. Fine-textured soils like clay have smaller pore spaces, leading to higher water retention but poorer drainage. Loam soils, a mix of sand, silt, and clay, offer a balance of drainage and water retention due to their varied pore sizes.
The size of rock particles are important to soil structure because the larger particles of sand allow rainwater to drain quickly through the soil, while the smaller particles of clay prevent rapid drainage.
It is a soil mix known as loam, which is a balanced combination of sand, silt, and clay that provides good drainage and nutrient retention.
Loam texture is desirable because it has a balanced mixture of sand, silt, and clay particles, which promotes good soil drainage, nutrient retention, and root penetration. This makes it ideal for plant growth as it provides a healthy balance of water retention and aeration.
There are three main types of soil and they are sand, silt, and clay. Almost all of the soil is a mixture of all three types. There are peaty, chalky, and loamy types of soil, too.
No, a retention pond is not the same as a lake. A retention pond is a man-made structure designed to manage stormwater runoff and reduce flooding by holding water temporarily, while a lake is a natural or large artificial body of water that usually has a more stable water level and ecosystem. Retention ponds typically have less biodiversity and are often part of a drainage system, whereas lakes can support a wider range of wildlife and recreational activities.
Drainage ditches are a method of controlling runoff from streets and highways where curbs and storm drains are not used. They are most often a shallow trough dug in the ground beside and parallel to the road surface. They collect runoff from the road and direct it either to a retention pond or a natural body of water.
Loam is good for farming because it has a balanced mixture of sand, silt, and clay particles, which provides good drainage, moisture retention, and nutrient retention for plant growth. It has a natural ability to hold onto both water and nutrients, making it an ideal soil type for various crops to thrive in.
A soil containing a lot of sand will have large particles with high drainage and low water retention capacity. In contrast, a soil with a lot of clay will have small particles with low drainage and high water retention capacity. Sandier soil tends to dry out quickly and doesn't hold nutrients well, while clay soil can become waterlogged and restrict root growth.
Soil texture is significant for crop production because it affects water retention, drainage, aeration, and root development. Fine-textured soils like clay hold water well but can become waterlogged, while coarse-textured soils like sand drain quickly but may dry out easily. The ideal soil texture for crops is loam, a balance of sand, silt, and clay that provides good water retention and drainage.
