- An irrigation stream of discharge 27m/s is diverted to a check basin of size 12m by 10m. The water holding capacity of the soil is...(Solved)
An irrigation stream of discharge 27m/s is diverted to a check basin of size 12m by 10m. The water holding capacity of the soil is 14%. The average soil moisture content in the crop root zone prior to applying water is 6.5%. If the average depth of the crop root zone is 1.2m, and the apparent specific gravity of the root zone is 1.50, determine how long the irrigation stream should be applied to the basin to replenish the root zone moisture to field capacity.
Given, Discharge, Q = 27 lit/sec
Area, A = 12 m × 10 m = 120 m2
Water holding capacity = 14%
Moisture content before irrigation = 6.5%
Depth of root zone, d = 1.2 m
Apparent specific gravity of the root zone soil = 1.5

Soil water holding capacity...(Solved)
The following data was used for irrigation a rectangular piece of land measuring:
360m by 240m using sprinkler irrigation;
Field capacity 22%
Wilting point 12%
Soil water holding capacity 1000mm per meter depth of soil
Root zone depth for crop in the field 1.2m
Soil bulk density 1.2g/cm3
Irrigation application efficiency 80%
Using the data provided calculate;
i) Net water requirement in mm
ii) Gross water requirement in mm
iii) Irrigation interval assuming that no rain falls during this period
iv) The volume of water in meters required to cover the whole field
