This depends on the soil!
Cohesionless coarse grained soils with high gravel contents may have high hydraulic conductivity on the order of 1 to 1x10-1 m/s.
Mixed sands and gravels are on the order of 1x10-1 to 1x10-3 m/s.
Finer sands approximately 1x10-3 to 1x10-4, and fine grained soils such as silty sands may be in the range of 1x10-5 to 1x10-7 m/s.
Very fine grained cohesive clay soils have very low hydraulic conductivity values ranging from 1x10-7 to 1x10-13 m/s.

What is the difference between an infiltration rate and a hydraulic conductivity?
It seems that infiltration rate is a soil parameter which is determined in the field with all soil aspects. However, hydraulic conductivity is determined in the lab and it is not typically illustrated soil permiability as compared with infiltration rate
What isw the Purpose of thermal conductivity in soil during cable laying?
The cabling to Earth is done for electrical conductivity, not for thermal conductivity. The general idea is to get rid of excess charges.
Is hydraulic fluid and hydraulic oil the same thing?
Hydraulic oil and hydraulic fluid are different. Hydraulic fluid is used in small systems such as car brakes. Hydraulic oil is used in large systems such as loaders.
What is a hydraulic bonds?
hydraulic bonds
How do hydraulic drills work?
with hydraulic's
Why is vertical hydraulic conductivity smaller than horizontal hydraulic conductivity?
Vertical hydraulic conductivity is typically smaller than horizontal hydraulic conductivity due to variations in the soil structure, compaction, and orientation of the soil particles. Vertical pathways for water flow are constrained by gravity, leading to reduced conductivity compared to the more open and interconnected pathways available for horizontal flow. Additionally, soil layering or stratification can further hinder vertical water movement, contributing to the lower vertical conductivity.

What is mean by saturated hydraulic conductivity?
Saturated hydraulic conductivity is a measure of how easily water can move through a saturated soil or rock material under a hydraulic gradient. It is commonly used in hydrogeology to characterize the permeability of a material and its ability to allow water to flow through it. The saturated hydraulic conductivity is influenced by factors such as porosity, particle size, and compaction of the material.
What factors influence the hydraulic conductivity of a glacial drift?
The hydraulic conductivity of glacial drift is influenced by factors such as grain size distribution, degree of consolidation, presence of fractures or bedding planes, mineral composition, and effective stress. Coarser-grained drift typically has higher hydraulic conductivity compared to finer-grained drift. Fractures and bedding planes can enhance the permeability of glacial drift, whereas the degree of consolidation and effective stress can affect the connectivity of pore spaces and water flow.
What is soil conductivity?
Soil conductivity is a measure of a soil's ability to conduct an electrical current. It is influenced by factors such as soil moisture content, soil texture, and the presence of salts and minerals. Higher soil conductivity levels can indicate higher levels of salinity, which can impact plant growth.
What is called a measurement of how much water flows through soil in a certain time?
This is called soil permeability or hydraulic conductivity. It is a measure of how easily water can pass through soil and is typically expressed in units of centimeters per hour.
What are the soil physical properties influencing irrigation?
Soil physical properties that influence irrigation include texture, structure, bulk density, porosity, and hydraulic conductivity. Soil texture affects water infiltration and retention, while soil structure influences root development and water movement. Bulk density determines water holding capacity, while porosity affects drainage and aeration. Hydraulic conductivity describes the soil's ability to transmit water. Together, these properties impact the efficiency of irrigation practices.
What has the author Willy V Abeele written?

What controls the rate of movement of ground water?
The porosity and permeability of the soil or rock control the rate of movement of groundwater. Other factors such as hydraulic gradient, hydraulic conductivity, and gradient also influence the speed at which groundwater moves through the subsurface.
What reaction does water have with soil?
Water interacts with soil through processes like infiltration, percolation, and hydraulic conductivity. It also affects soil structure by influencing soil erosion, compaction, and nutrient transport. Water can dissolve minerals in the soil, altering its chemical composition and affecting plant growth.
What is dewatering methods used to dewater foundation soil and for ground conditions they are best suited?
It all depends on the hydraulic conductivity of the surrounding soils. Well point systems or trench systems have their own advantages and disadvantages.
A rocks ability to allow water to pass through is called a what?
Permeability/ hydraulic conductivity.
