    Study Notes

    General Irrigation Terminologies

    • The Philippine National Standard PNS/BAFS/PAES 216:2017 focuses on irrigation terminology essential for classification, planning, design, construction, and operation.
    • Initiated by AMTEC, this standard supports precision farming through improved nutrient and water use efficiencies.
    • The development process is guided by the Agricultural and Fisheries Mechanization Law (Republic Act 10601) and involves collaboration with the Department of Agriculture (DA) and other relevant bodies.

    Key Definitions in Irrigation

    • Access Areas: Publicly accessible spaces such as parks and golf courses.
    • Active Storage: Water volume in a reservoir between minimum and normal water levels.
    • Actual Crop Evapotranspiration: Actual water loss affected by soil water levels, salinity, and field size.
    • Afflux Elevation: Increase in flood levels due to obstacles like dams.
    • Algal Bloom: Excessive algae growth in water, potentially toxic to aquatic ecosystems.

    Irrigation Efficiency and Water Management

    • Application Efficiency: Ratio of infiltrated water in the root zone to water applied.
    • Aquifer: Geological formation that contains water and can yield it economically via wells.
    • Conveyance Efficiency: Ratio of water received at the inlet to that delivered at the project’s headworks.
    • Effective Rainfall: Rainwater that contributes to crop growth, excluding losses from deep percolation and runoff.
    • Crop Water Requirements: Total water consumption including evapotranspiration and losses.

    Infrastructure and Techniques

    • Basin Irrigation: Water applied to level fields enclosed by dikes, retaining water until it soaks into the soil.
    • Drip Irrigation: Low-rate water application directly to plant roots to minimize waste.
    • Diversion Dam: Structure built to augment irrigation by directing water from natural sources into canals.
    • Lined Channel: Canals with impermeable surfaces to reduce seepage and stabilize the channel.

    Key Metrics and Factors

    • Crop Coefficient: Relationship between actual and potential crop evapotranspiration.
    • Design Irrigable Area: Maximum area an irrigation project can optimally serve based on land and water availability.
    • Distribution Uniformity: Measure of how evenly water is applied across agricultural systems.
    • Freeboard: Extra height of a dam for safety against overtopping.

    Soil and Water Interactions

    • Hydraulic Radius: Cross-sectional flow area divided by wet perimeter, affecting flow efficiency.
    • Leaching: Percolation of water beyond root zones aiding in salt and nutrient loss.
    • Contamination: Presence of unwelcome substances in water, diminishing its usability.

    Regulatory and Environmental Considerations

    • Effluent Standard: Legal limits on the discharge of pollutants into water bodies.
    • Hydrologic Frequency Analysis: Statistical estimation of event occurrences based on hydrologic data samples.
    • Karst Topography: Landscape formation resulting from soluble rock dissolution, impacting water flow and storage.

    Practical Applications

    • Embankment Design: Requires consideration of materials, bearing capacities, and settlement for stability.
    • Irrigation Period: Time taken to effectively cover an area with water, critical for scheduling.
    • Farm Water Requirement: Calculated need for irrigation accounting for effective rainfall and crop needs.

    Professionals Involved

    • The document highlights the contributions of various agricultural engineering professionals and institutions, underscoring a collaborative approach to standard-setting in irrigation practices.

    These points encapsulate the core contents and essential definitions related to irrigation within the Philippine National Standard for effective study and reference.
