WATER QUALITY/QUANTITY
Flow meters are used to measure and manage the amount of
water flowing through a pipe. The amount of flow plus the amount of time the
well is operating plus the size of the field is used to determine the amount of
water applied to a field. This is normally expressed in acres inches of water.
The capture of field runoff is called tail water recovery.
The runoff is stored in an enclosed ditch, pond, or lake. The stored water can
be re-lifted and used to irrigate crops. Re-lifting the water is cheaper than
operating a well. Another benefit to water quality is that the sediment settles
out and does not leave the farm. Tail water recovery reduces the negative
impact on the ground water aquifer.
Slotted Board Riser demonstrates water management and field
grade control. The boards are inserted at the inlet to hold water and can be
used to control the outlet elevation of the field. When water is held in a
field, soil sediments are allowed to settle out allowing clean water to leave
the field. Winter flooding of fields maximizes sediment retention and wildlife
enhancement during winter months.
Box Inlet Pipe is used to safely drop tail water into the
outlet ditch. This type pipe prevents erosion into the field by stabilizing the
ditch grade.
Side inlet irrigation is used to irrigate fields with straight levees filling each paddy at the same time. It results in less water being used to irrigate a crop. For this reason side inlet irrigation is a tool to manage water quantity usage on a farm. This practice saves water, time, and labor. It reduces excess runoff.
