Abstractions from Precipitation
This chapter discusses abstraction processes in the hydrologic cycle, specifically focusing on evaporation, interception, and infiltration. It provides insights into measurement techniques and methods for estimating evaporation and evapotranspiration. Techniques for reducing reservoir evaporation and the classification of infiltration capacities are also covered, emphasizing their importance for water resource management and irrigation planning.

What we have learnt
- Abstractions from precipitation do not contribute to surface runoff due to various processes.
- Measurement and estimation methods for evaporation and evapotranspiration are crucial for effective water resource management.
- Infiltration capacity influences runoff and is affected by various soil and environmental factors.
Key Concepts
- -- Evaporation
- The process of water changing from liquid to vapor, primarily from open water, soil, and vegetation.
- -- Evapotranspiration
- The combined process of evaporation from soil and water surfaces and transpiration from plant surfaces.
- -- Infiltration
- The process by which water enters the soil surface.
- -- Potential Evapotranspiration (PET)
- The maximum loss of water from a surface under ideal moisture conditions.
- -- Actual Evapotranspiration (AET)
- The actual amount of water lost from the soil and surfaces under prevailing conditions.
