It is the rate of flow of water through the soil layers. This is important information that is used for geotechnical site investigation. Geotechnical and civil engineers as well as hydrogeologists and environmental scientists use this information for various projects. It is important to understand the hydrologic characteristics of the soil good flood management pracitces, embankments and dams designs.
BHM Geotechnical offers several geotechnical services in Sydney including soil permeability testing. Here is why this is important:
This is essential for various applications like when building a on-site detention tank or bioretention system. It is crucial to understand permeability of the soil to ensure an appropriate design. The amount of seepage depends a great deal on the granular soil skeleton.
It is essential for engineers and agriculturists to study the fluid flow through the soil mass when working with soil.
The level of soil permeability affects the supply of air, moisture and nutrition from the roots.
Excavation sites often have to deal with the issue of seepage water. The measure of soil permeability can help provide vital information for a construction site.
It is vital to ensure the stability of earthen structures like retaining walls, dams, etc.
It is critical for the good management to mitigate the effects of natural disasters like floods as well as effluent infiltration.
Several factors affect soil permeability like hydraulic gradient, soil type, texture, particle size, moisture, porosity and more. A
Constant Head Test: This involves collecting samples of the soil for laboratory tests. This method involves forcing water with a piston through a column of water-saturated soil. This is necessary to determine the rate of flow of the water. This method is useful for sand, gravel and also several types of clay soils.
Falling Heat Test: This test is usually meant for fine-grained soil and involves allowing the head to decrease as water is introduced to the sample. This will diminish the pressure gradually.
The relation between soil and water affects its permeability in many ways. Some of the common issues faced with soil during agriculture, construction, etc. include:
