ISAAC – Irrigation System Analysis and Computation

ISAAC is PC software designed to make a number of computations to determine the application uniformity of irrigation systems. Basically a number of observation measurements in the field are collected and entered to make the computation. The resulting report may be printed, saved as a universal RTF file, saved to HTML (for web use) or saved for future reference. The raw data may also be saved to reference at a later date.

This program is provided by the University of Georgia Cooperative Extension Service via Stripling Irrigation Research Park. For further information contact Calvin Perry, perrycd@uga.edu. It was developed by Kerry Harrison, retired UGA Extension Irrigation Specialist.

System Requirements: ISAAC is designed to work under Windows 95/98/2000 (but should work with newer versions of Windows in compatibilty mode) and should operate satisfactorily on any PC system that will run any of these operating systems. The installation will require up to 5 MB of disk space depending on the system configuration. Note – after clicking on the download button below, the “autorun.exe” file will be downloaded into your particular “downloads” folder. Usually a download reminder/info line will be displayed at/near the bottom of your browser window. The “autorun.exe” file should be copied into an appropriate folder and then the file can be double-clicked to start the install process, following prompts.

Spring Center Pivot and Lateral Irrigation System Preparation
The main objective of this fact sheet is to provide a checklist of what is needed to properly prepare a center pivot or lateral irrigation system for the production season. All of the topics covered apply to both pivot and lateral irrigation systems, but for brevity, only center pivots will be referenced. By using the items in this fact sheet as a guideline for preventative maintenance, most breakdowns during the growing season should be avoided.

Evaluating and Interpreting Application Uniformity of Center Pivot Irrigation Systems
With rising fuel prices it is increasingly important that irrigation systems apply water uniformly in order to achieve maximum benefit from the water applied. The uniformity of water application under a center pivot is determined by setting out cans or rain gauges along the length of the pivot, bringing the irrigation system up to proper operating pressure, and letting the system pass over them.

Cost of Irrigation Ownership and Operating Costs through Irrigation Budgets for South Georgia
These irrigation budgets, developed by University of Georgia Cooperative Extension, are estimates of the irrigation costs of a center pivot irrigation system located in southeast Georgia. Our intention is to provide flexible, user-friendly irrigation budgets with default values. That being said, the variation among different farm conditions can impact investment costs and annual costs associated with irrigation; users are suggested to modify these default values and customize their budgets according to their specific field conditions. Please consult your irrigation providers for properly designed center pivot systems that match well production to achieve your irrigation goals. This should serve as a generalized user guide for irrigation budgets and provide guidance for adjusting the default values in the budgets.
