Canal lining is the engineering practice of applying an impermeable layer to the bed and sides of a canal. This layer minimizes water loss due to seepage, which can be significant in unlined canals, reaching 30-50% of the total water flow.

Properties of Canal Lining:

Impermeability: The primary function of a canal lining is to be watertight, preventing water from seeping into the surrounding soil.

Durability: The lining material needs to withstand constant water exposure, weather elements, and potential erosion from the water flow.

Strength: The lining should be strong enough to handle the weight of the water and any external loads it might encounter.

Smoothness: A smooth lining reduces friction between the water and the canal walls, allowing for improved water flow efficiency.

Cost-effectiveness: The chosen lining material should offer a balance between effectiveness and affordability.

Supporting Equation:

One important equation used in canal design related to lining is the Manning's equation, which helps calculate the velocity of water flow in open channels like canals.

Manning's equation:

V = (1/n) * R^(2/3) * S^(1/2)

Where:

V - Average velocity of water flow (m/s)

n - Manning's roughness coefficient (dimensionless) - A value that depends on the friction between the water and the canal lining material. Lower 'n' values indicate smoother surfaces and higher flow rates.

R - Hydraulic radius (m) - The area of the water flow section divided by its wetted perimeter.

S - Slope of the canal bed (m/m)

Example:

A concrete canal lining is designed for a canal with a bottom width of 5 meters, side slopes of 1:1 (horizontal:vertical), and a water depth of 2 meters. The canal bed slope is 0.001 (1 meter drop per kilometer).

Step 1: Calculate the wetted perimeter (P):

P = bottom width + 2 * water depth * (1 + slope^2)^1/2

P = 5 + 2 * 2 * (1 + 0.001^2)^1/2

P ≈ 9.02 meters

Step 2: Calculate the flow area (A):

A = bottom width * water depth + (water depth^2) * slope

A = 5 * 2 + (2^2) * 0.001

A = 10.002 meters^2

Step 3: Calculate the hydraulic radius (R):

R = A / P

R = 10.002 / 9.02

R ≈ 1.11 meters

Step 4: Assuming a Manning's roughness coefficient (n) for concrete of 0.013:

We can use Manning's equation to estimate the average water velocity (V) in the canal. However, due to the complexity of the equation, it's easier to solve for V using computational tools or pre-made tables based on Manning's equation.

This is a simplified example, and actual canal design involves various factors and considerations beyond this basic example

Channel capacity, in the context of open channel flow, isn't directly defined by just length, width, slope, and Manning's roughness coefficient. It's a concept related to the maximum flow rate a channel can handle before experiencing undesirable conditions like overflow or excessive erosion.

Here's a breakdown of the relevant factors:

Geometric factors:

Length (L) in meters: Plays a role in frictional losses along the channel bed.

Width (B) in meters: Determines the cross-sectional area available for water flow.

Wetted perimeter (P) in meters: The portion of the channel bed and sides in contact with flowing water, affecting friction. (Wetted perimeter can be calculated based on L, B, and water depth)

Hydraulic factors:

Slope (S) in meters per meter: Represents the channel's downward inclination, driving the flow velocity.

Manning's roughness coefficient (n): Accounts for the resistance offered by the channel's surface to flow.

Calculating Flow Rate:

We can estimate the channel capacity (maximum flow rate) using Manning's equation:

V = (1/n) * (R^(2/3) * S^(1/2))

where:

V = Average flow velocity (m/s)

n = Manning's roughness coefficient

R = Hydraulic radius (m) - This is the ratio of the channel's cross-sectional area (A) to the wetted perimeter (P) R = A/P

S = Slope (m/m)

Important Note: Manning's equation only provides the average flow velocity. To determine the maximum flow rate (channel capacity), we need the channel's cross-sectional area (A).

Example:

Imagine a trapezoidal channel with the following properties:

Length (L) = 100 meters

Bottom width (B) = 5 meters

Side slope (1:1) - This means for every 1-meter increase in height, the side widens by 1 meter on each side.

Slope (S) = 0.002 m/m

Manning's roughness coefficient (n) = 0.030 (assuming bare earth)

Steps:

Calculate the wetted perimeter (P) for a specific water depth (h):

This depends on the water depth and channel geometry. We'll need to use trigonometry for a trapezoidal channel.

Calculate the hydraulic radius (R) based on the water depth (h) and the previously calculated wetted perimeter (P):

R = A (channel cross-sectional area at that water depth) / P

Use Manning's equation to solve for the average flow velocity (V) for that specific water depth (h):

V = (1/n) * (R^(2/3) * S^(1/2))

Multiply the average flow velocity (V) by the channel's cross-sectional area (A) at that water depth (h) to get the flow rate (Q):

Q = V * A

Repeat steps 1-4 for different water depths (h).

By plotting the calculated flow rates (Q) for various water depths (h), you can identify the maximum flow rate the channel can handle before encountering problems. This maximum flow rate represents the channel capacity in this scenario.

Remember: This is a simplified example. Real-world scenarios might involve irregular channel shapes or require additional considerations like channel stability analysis. Consulting a hydraulic engineer is recommended for critical projects.

Manning's Roughness Coefficient's probable values:

Here's a probable range of Manning's roughness coefficient (n) values for some common slope protection materials:

Smooth concrete panels: 0.012 - 0.014 (This assumes a trowel finish with minimal imperfections)

Shotcrete (gunite) with good section: 0.016 - 0.019

Riprap (dry rubble): 0.020 - 0.030 (This can vary depending on stone size and gradation)

Gravel surface: 0.022 - 0.025

Bare earth: 0.022 - 0.025

Grass with few weeds: 0.022 - 0.027

Dense grass or vegetation: 0.030 - 0.040

Remember: These are just a starting point. The actual n value for your specific case can be higher or lower depending on factors like:

Surface irregularities: Rougher surfaces will have a higher n value than smooth ones.

Vegetation density and type: Denser vegetation or plants with higher resistance to flow will increase n.

Channel geometry: The shape and size of the channel can also influence n.

For more precise values, it's recommended to consult established references like the one mentioned previously ([Guide for Selecting Manning's Roughness Coefficients for Natural Channels and Flood Plains]) or seek guidance from a qualified engineer familiar with hydraulic calculations.

Irrigation Calculator:Engineering & Science Calculators: Free Online Tools

Definition: Irrigation system water demand is the amount of water required to meet the evapotranspiration (ET) needs of the crop, considering the irrigation efficiency. In other words, it's the volume of water that needs to be applied to the crop zone after accounting for losses due to evaporation, deep drainage, and other factors.

The three factors crop coefficient (Kc), irrigation efficiency (Ei), and irrigation time period, all play a crucial role in determining irrigation water demand

Understanding Irrigation Management: Crop Coefficient, Irrigation Efficiency, and Irrigation Time Period

Crop Coefficient (Kc):

The crop coefficient (Kc) is a factor that accounts for the difference in water use between a specific crop and the reference crop (usually well-watered grass). It essentially tells you how much a particular crop transpires compared to the reference crop under the same conditions. Kc values vary depending on the crop type, growth stage, and climatic conditions. For example, corn will have a different Kc than tomatoes, and both will have varying Kc values throughout their growing seasons.

Example of various Crop Coefficient:

Here's a table listing crop coefficients (Kc) for various irrigation plants in general use. These are averages and can vary depending on the specific growth stage and climatic conditions. It's always recommended to consult local resources or agricultural extension services for the most accurate Kc values for your specific situation.

Crop Type Kc Range

Alfalfa

1.10 - 1.25

Barley

0.80 - 1.10

Corn

0.80 - 1.10

Cotton

0.80 - 1.20

Fruits (orchards)

0.70 - 1.00

Grass (lawns)

0.70 - 0.85

Peanuts

0.80 - 1.10

Potatoes

0.70 - 1.00

Rice

1.00 - 1.20

Soybeans

0.80 - 1.10

Sugarcane

1.20 - 1.40

Tomatoes

0.70 - 1.10

Vegetables (general)

0.70 - 1.00

Wheat

0.80 - 1.10

Remember, these are just a general guide. For the most accurate Kc values for your specific crop and location, consult with local agricultural resources or extension services. They can provide Kc data specific to your region and crop variety.

Irrigation Efficiency (Ei):

Irrigation efficiency represents the percentage of irrigation water that reaches the plant root zone for beneficial use by the crop. Unfortunately, some water is lost during the irrigation process due to factors like evaporation, wind drift, runoff, or deep drainage beyond the root zone. A higher irrigation efficiency signifies less water waste. Different irrigation methods have varying efficiencies, with drip irrigation being generally the most efficient, followed by sprinkler and surface irrigation methods.

Irrigation Time Period:

The irrigation time period refers to the interval between irrigation events. It's determined by the crop's water needs, soil moisture capacity, and climatic conditions (mainly temperature, humidity, and wind speed) that affect evapotranspiration (ET). ET is the combined process of evaporation from the soil surface and transpiration from the plant. By monitoring soil moisture or relying on ET data, farmers can determine the appropriate time period between irrigations to ensure adequate water supply for the crop without overwatering.

Calculating Irrigation Water Demand:

The following equation helps estimate the total water demand (ETc) for your crop over a specific period:

ETc = ETo x Kc x Time Period

where:

ETc - Crop Evapotranspiration (total water demand in mm or inches)

ETo - Reference Evapotranspiration (data typically available from weather stations or calculated using various methods)

Kc - Crop Coefficient (specific to your crop and growth stage)

Time Period - The time interval between irrigations (days)

Daily or Cycle Demand:

To determine the daily or cycle water demand, simply divide the total water demand (ETc) by the number of days (or cycles) in your irrigation time period.

Putting it All Together:

By understanding crop coefficient, irrigation efficiency, and irrigation time period, farmers can create an efficient irrigation plan. They can use the equation above to estimate the total water needs of their crop and then adjust for irrigation efficiency to determine the amount of water to apply. Monitoring soil moisture or relying on ET data helps determine the appropriate irrigation time period to ensure the crop receives water when needed without wasting water.

Example:

Imagine you're growing corn during a period with an average daily ETo of 5 mm and a Kc value for corn at that stage is 0.8. If you're using a drip irrigation system with an efficiency of 85%, and your soil conditions allow for irrigations every 3 days, here's how to calculate your irrigation needs:

Total Water Demand (ETc) for 3 days:

ETc = 5 mm/day x 0.8 x 3 days = 12 mm

Water to Apply Considering Efficiency:

Water Needed = ETc / Irrigation Efficiency

Water Needed = 12 mm / 0.85 = 14.1 mm

Therefore, you would need to apply approximately 14.1 mm of water through your drip system every 3 days to meet the crop's water needs during this period.

Remember, these are estimations, and real-world conditions can vary. Monitoring soil moisture and adjusting irrigation practices as needed is crucial for optimal water management.
