coefficient of permeabilityChestermiller said:
No. They are the hydraulic conductivites. Do you know the definition of hydraulic conductivity?fonseh said:
it is to measure the permeability . Why there's no horizontal hydraulic conductivity in the example above ?Chestermiller said:
Because the flow is vertical, and the pressure is constant over all horizontal planes.fonseh said:
do you mean the water can't flow horizontally thru different layer ? so there is no horizontal permeability ? Why ?Chestermiller said:
There is horizontal permeability, but the flow is in the vertical direction (according to the problem description).fonseh said:
Can you point out whoich part of the problem stated the flow is vertical ? The water can also flow in horizontal direction across different layer of soil A, B and C , right ?Chestermiller said:
This is not the way I remember the problem. Maybe I'm thinking of a different problem. In this problem, the flow is purely horizontal, with no vertical component.fonseh said:
Do you mean it's vertical flow? Not horizontal flow ?Chestermiller said:
Since the flow is horizontal , why there's no horizontal permeability ?Chestermiller said:
Can you point out which part show that the flow is horizontal ?Chestermiller said:
The three layers in the figure are inside a tube which is obviously horizontal.fonseh said:
The problem statement says that the tabulated values of hydraulic conductivity are in the direction of flow.fonseh said:
why ? The water can flow both horizontally and vertically . Why there's only vertical permeability ?Chestermiller said:
Previously , you pointed out that the flow is horizontal , if so , why there's no horizontal permeability in this question ?Chestermiller said:
You are aware of the relationship between the permeability and the hydraulic conductivity, correct?fonseh said:
yes, can you explain further ?Chestermiller said:
Previously , you pointed out that the flow is horizontal , if so , why there's no horizontal permeability in this question ?Chestermiller said:
So , the flow is only vertical flow ? no horizontal flow ?Chestermiller said:
THE FLOW IN THIS PROBLEM IS HORIZONTAL. THE DATA IN THE TABLES ARE THE HYDRAULIC HYDRAULIC CONDUCTIVITIES. IF YOU KNOW THE HYDRAULIC CONDUCTIVITES, THEN YOU DON'T NEED TO KNOW THE PERMEABILITIES IN HEAD CALCULATIONS.fonseh said:
Hydraulic conductivity in soil is a measure of the ability of soil to transmit water. It is a property that describes how easily water can flow through the soil and is influenced by factors such as soil texture, structure, and moisture content.
Hydraulic conductivity is typically measured using a constant-head or falling-head permeameter, which involves applying a known pressure or head to the soil and measuring the rate of water flow through a specific area of soil.
Hydraulic conductivity in soil is affected by several factors, including soil texture, structure, compaction, moisture content, and the presence of organic matter. Coarser soils with larger pore spaces generally have higher hydraulic conductivity compared to finer soils with smaller pore spaces.
The higher the hydraulic conductivity of soil, the easier it is for water to flow through it. This can impact the movement of water through the soil profile, such as how quickly water infiltrates into the soil or how easily it moves laterally through the soil layers.
Hydraulic conductivity is an important factor in understanding water movement in soil, which is crucial for agricultural and environmental studies. It can impact the efficiency of irrigation and drainage systems, nutrient transport in soil, and the movement of pollutants through the soil profile.
