Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Design Example: Design of an Irrigation Channel

Design Example: Design of an Irrigation Channel

Trapezoidal channels are widely used in irrigation systems due to their cost-effectiveness and efficiency in conveying water. Trapezoidal channels feature a flat bottom and sloping sides, making them stable and easier to construct compared to other shapes. The bottom width and side slope ratio are determined based on the required flow capacity and site conditions. The side slope is kept gentle for unlined channels to prevent soil erosion.Hydraulic parameters in channel design include the flow...

Regulation of Water Output

Regulation of Water Output

The human body predominantly expels water through the urinary system. On average, an individual generates around 1.5 liters of urine each day. This amount can fluctuate based on how well a person is hydrated, but a critical minimum quantity of urine must be produced to ensure the body's proper functioning. Daily, the kidneys remove 600 to 1200 milliosmoles of dissolved substances, effectively excreting excess minerals and water-soluble toxins such as creatinine, urea, and uric acid from the...

Underflow Gates

Underflow Gates

Underflow gates are vital for controlling water flow in irrigation canals. The three main types of underflow gates — vertical, radial, and drum gates — serve different purposes while ensuring effective flow management. Vertical gates move up and down, generating a free-flowing water jet; radial gates pivot to regulate the flow; and drum gates rotate for precise adjustments. The flow through these gates is influenced by downstream conditions, resulting in free or drowned outflow.Free and Drowned...

Conservation of Mass in Moving, Nondeforming Control Volume

Conservation of Mass in Moving, Nondeforming Control Volume

Stormwater detention basins are essential in managing runoff during heavy rainfall, particularly in urban areas where impervious surfaces increase the risk of flooding. Understanding the conservation of mass in these systems allows engineers to optimize basin performance, balancing inflow, outflow, and water storage.
In the context of a detention basin, the conservation of mass states that the total mass of water entering the basin must equal the mass leaving the basin plus any accumulation of...

Summary

Maximizing crop production per unit of water is crucial due to increasing water scarcity. Deficit irrigation, applying less water than crops need, is a key strategy to improve water productivity and profitability.

Area of Science:

Agricultural Science
Water Management
Agronomy

Background:

Irrigated agriculture faces increasing water scarcity, necessitating a shift towards water productivity.
Deficit irrigation, supplying less than full crop water requirements, is a vital strategy for water conservation.

Purpose of the Study:

To review the application of deficit irrigation for biomass production and crop irrigation.
To assess the potential for improving water productivity in field crops and fruit trees.

Main Methods:

Review of existing research on deficit irrigation strategies.
Analysis of case studies on regulated deficit irrigation (RDI) in fruit trees and vines.

Main Results:

Deficit irrigation can significantly reduce water consumption while maintaining crop yield.
Optimal deficit irrigation levels often involve supplying 60-100% of full evapotranspiration.
Regulated deficit irrigation (RDI) has demonstrated increased water productivity and farmer profits in fruit crops.

Conclusions:

There is substantial potential to enhance water productivity through deficit irrigation strategies.
Further research linking physiological responses to RDI design can accelerate adoption in water-limited regions.
