Irrigation adventures in the desert
By:Adam West
This poster photographically documents an irrigation experiment conducted in Southern Utah. The aim of this experiment was to examine the responses of the dominant woody species in an Piñon-Juniper woodland to a simulated summer rainfall event. The experiment took place in the summer of 2004.
Loaded up and ready to go...
Arrived at the site to a stormy sunset.
Setting up the irrigation gear and transferring water from the 16,000 liter delivery tanker.
Filled tanks and storage pool.
Water was pumped from the tanks into 600ft of fire hose trunk-line laid out across the woodland.
We ran 100ft hoses from taps set into the fire hose trunk-line. These hoses were moved from tree to tree.
That evening we begun irrigation and planned to irrigate through the night.
However, rain showers and lighting interfered with this plan.
Waiting for the rain to pass and to assess the situation.
As the storm passed, we were treated to a spetacular sunset.

It had rained 5mm in little over an hour, not a big event. Based on this we decided to go ahead.
However, we were again kept at bay by a lightning storm. Standing out in the open waving a metal hose wand around was deemed not to be the brightest idea, so we waited it out in camp.
We got back out there at 4am to finish the irrigation before the evaporative demand got too high. 
After the previous setbacks, things went really smoothly. We finished the irrigation just after the sun came up.

A big thanks to all those who braved the heat, the rain and lightning and the sleepless nights to make this experiment a success. Special thanks to Tim Jackson (Mr. Irrigation) and Kevin Hultine.
