Lecture
This lecture covers the concepts related to water usage and consumption for irrigation purposes, including potential evapotranspiration, soil moisture dynamics, traditional vs micro-irrigation, and soil salinization. It explains the dynamics of salt concentration in the soil due to irrigation, the impact of different irrigation methods on soil salinization, and countermeasures to prevent salt accumulation. The lecture also discusses the calculation of soil moisture and salt concentration based on precipitation intensity and evapotranspiration. Various irrigation schemes and their effects on water usage and soil conditions are explored.
