Disclosed is a system and method usable for controlling multiple flows of water. The system may include a first sensor configured to sense a condition, a first drain tile, a first flow regulator configured to control a flow of water in the first drain tile, and a first transceiver configured to control the first flow regulator based on the sensed condition.

A surge irrigation system includes a main inlet pipe configured to be coupled to a source of pressurized water. The main inlet pipe is coupled to a flow meter for the purpose of improving furrow irrigation. The system further includes two independent, valve-actuated and controlled pipe arm segments extending from the main inlet pipe. One of the pipe arm segments extends toward a first irrigation zone in a field, and the second pipe arm segment extends toward the second irrigation zone in the field. The system further includes water advance sensors for the purpose of improving a surge irrigation program for an improved autonomous and parameter-setting operation. Additionally the controller, sensor and interface use radio communication.

Apparatus, systems and methods for irrigating lands are disclosed. In one example, an irrigation system is disclosed. The irrigation system includes a gate and a microcontroller unit (MCU). The gate is configured for adjusting a water flow for irrigating a piece of land. The MCU is configured for controlling the gate to adjust the water flow based on environmental information related to the piece of land.

An arrangement for controlling and measuring flow. The arrangement includes a fluid control barrier and a flow-measuring apparatus upstream of the fluid control barrier. The fluid control barrier includes a pair of plates for opening and closing a pipe, and the plates are movable towards a center line of the pipe to open the pipe and produce a symmetrical flow profile for the flow-measuring apparatus.

A cable drive device including an arcuate segment drive member and a cable drum having an axle to allow rotation of the cable drum. The cable drum has a cable affixed at either end of the arcuate section of the arcuate segment drive member and tautly wrapped around the cable drum. The cable drum is located between the ends of the arcuate section of the arcuate segment drive member to, in use, allow the arcuate segment drive member to be moved when the axle is rotated. The cable is located in a groove in the arcuate section and a part of the cable drum extends into the groove, and the cable drum and the arcuate segment drive member simulate a rack and pinion drive.

A system of harvesting sea creatures from a trench holding the sea creatures in seawater, including a trench, an injection well, and a harvesting apparatus that extracts the sea creatures from the trench. The trench includes a gate at one end of the trench. The gate insertable into an opening at the end of the trench to prevent seawater from entering or exiting the trench and removable from the opening to allow the seawater to enter or exit the trench. The injection well is positioned external to the trench and can receive the seawater discharged from the trench. The harvesting apparatus includes a conveyor that inclines. The conveyor includes a conveyor belt and a wedge at one end of the conveyor that contacts the bottom floor of the trench when the conveyor is inclined.
