| Type | Name | Date | Summary |
 | Convert - Calculator for conversions (Unknown) | | Calculator for converting flow rates, force, light, energy, distance, density, power, mass, concentration, area, computer, volume, torque, time, temperature, angle, acceleration and speed. Reliability unknown. Needs Winzip to unzip. |
| Farm Excel: Conversions (FarmExcel) | 1999 | Calculator for conversions including length (height and distance), area, volume, mass, mass/area, density and miscellaneous. Includes calculator for salinity conversions.Reliability unknown. |
| Farm Excel: Farm Tips (FarmExcel) | 1999 | Calculator for farm planning including working out the costs of fencing, and calibration of boom spray, calibration of a seeder or combine or fertiliser. |
| PUMPS (George, R.) | 1997 | A spreadsheet model used to evaluate the long term benefits and costs of installing groundwater pumping systems on farms to reclaim saline seeps. PUMPS allows analysis of conventional, airlift and solar pumping systems. |
| Banks Surface Water Control (Paddock scale) (George, R.) | 2002 | BANKS is used to evaluate the long term benefits and costs of installing various bank layouts on farm to manage water erosion. BANKS incorporates the impact of water erosion on organic nitrogen and soil depth and relates these to crop yields using user defined input values. |
| DRAINS (George, R.) | 2002 | DRAINS is used to evaluate the long term benefits and costs of installing drains on farm to alleviate soil waterlogging. The model incorporates a random generator for rainfall events and flexibility to model a wide range of drain configurations. |
| AgET Water Balance Calculator (Raper, P.) | 2005 | AgET is a simple water balance calculator which you can run on your computer (unzip and select SETUP). AgET helps farmers and their advisors understand how differing climates, plants, soils and rotations influence components of the water balance (i.e. evapotranspiration, runoff and deep flow). The model uses ‘average’ climate, and ‘representative’ soil and plant information obtained within the agricultural areas of Western Australia. To operate AgET, the user selects a site, soil unit, and plant or farming system of interest, and then runs the model against any other farming systems that may be suited to that environment. These calculations can be undertaken for a range of annual or perennial plants used within current farming systems. |
 | Leakage Calculator (Website information)(Raper, P.) | 2004 | The Leakage Calculator was developed by the "A Million Hectares for the Future" team for use in the Introduction to Salinity Workshop. The aim was to help farmers and their advisors quantify the amount of water leaking past the root zone of agricultural plants with a view to tailoring recharge minimising strategies for salinity management. It is assumed that other salinity management strategies are considered and employed, where appropriate. The Leakage Calculator is a simple spreadsheet in which the calculation of runoff, evaporation, transpiration and deep drainage (leakage) have already been performed using the Department of Agriculture soil water balance model, AgET. There are seven versions of the Leakage Calculator, each representing an area of the south-west agricultural region. It was designed to be used by non-specialist presenters with little or no training. |
| Catcher - A companion program to AgET (George, R.) | 2002 | Catcher is a "Back of the Envelope" calculator for analyzing catchment water balances - how much rain falls (RAIN), how much water evaporates and is used by crops (Et), how much runs off (RUNOFF), and how much disappears into the sub-soil (DEEP FLOW). Unzip and select SETUP). It uses monthly point-value estimates of Et, RUNOFF and DEEP FLOW from the AgET program, adds them up for a given catchment, and allows users to see how much effect different crop plantings in different areas of a catchment can have on the catchment water balance. The Catcher program is a product of the Avon Drainage Working Group and the Department of Agriculture. It was developed as an extension tool to assist catchment groups to understand the relative components of their catchment water balance. |
