About Application

About this application:

This app calculates erosion and sediment loss rates, pre and post-mitigation for a given paddock based on slope, location, ground cover, row lengths and mitigation measures.

The application uses research results from the SFF project Don’t Muddy the Water as well as factors from the Revised Universal Soil Loss Equation (RUSLE) to model erosion rates.



Disclaimer:

It is assumed that all erosion and sediment control measures have been established and maintained correctly according to guidelines. Results will be misleading if the mitigation measures are not being implemented correctly.

User Guide

How to use this application:

This app calculates rates of erosion from horticultural paddocks for both with (mitigated) and without (baseline) mitigation measures in place. The application has been designed to be easy to use and can be downloaded onto a mobile device by following the steps below:

Once opened, follow the link on the home page or the menu to the calculator and input the data on each page. The final page displays the results, and this page can also be navigated to directly through the menu. Results can also be downloaded as a text file for record keeping.

To obtain useful data on erosion rates, it is necessary to input data as accurately as possible and requires an accurate assessment of the size and effectiveness of existing mitigation measures.
