Irrigation and Its Methods in Civil Engineering Study
Irrigation and Its Methods for Engineering Purpose Irrigation CHAPTER HIGHLIGHTS ☞ Introduction ☞ Types of irrigation ☞ Methods of irrigation ☞ Water requirements of crops ☞ Irrigation efficiencies ☞ Irrigation requirements of crops ☞ Crop seasons ☞ Water logging and drainage GENERAL UNDERSTANDING The following are the main concerns on irrigation:- 1 How to apply i.e. what should be the method of irrigation: Border Flooding method, furrow irrigation method,sprinkler irrigation method, drip irrigation method etc. 2.How much apply i.e. how much moisture the soil can hold in its pores or Moisture holding capacity of Soil. 3.When to apply i.e. when has the soil moisture level depleted to 50 to 60% of moisture holding capacity and when is the time to irrigate. In other words, what should be the frequency of irrigation. DEFINITION OF IRRIGATION Irrigation may be defined as the science of artificial application of water to the land, in accordance with the crop requirements throughou...
