Slope-Area Method Discharge Calculator (SAMDC)

The Slope-Area Method Discharge Calculator (SAMDC) is a stand-alone software tool that can be used to complete the data analyses described in:

Brown, S., and Metcalfe, R.A., 2014. The slope-area method for estimating continuous discharge. Ontario Ministry of Natural Resources. 13p.

The document describes the background and underlying methodology to use the slope-area method to develop a continuous discharge time series at a remote site. It is intended as a method to employ at sites where time or logistical constraints preclude the development of a rating curve. Its utility is in the ability to obtain at least some information on the flow regime of an ungauged site that can aid decision making in the absence of any other streamflow information.

The software is being provided "as-is". Unfortunately we cannot offer in-depth technical support but the software has a well documented manual and is robust enough that you should not encounter any issues.

How to download and unzip the software package

SAMDC is free. Making this tool available helps to improve our understanding of a watershed's hydrology which can inform resource management decisions. All that is asked is that you send an email requesting the password to unzip the software. We would also appreciate brief information about your intended application and where you are in the world. Knowing the number of users and the applications will help guide decisions on further development and investment. Your privacy will be respected. For important bug fixes and updates, check back here regularly.

SAMDC is programmed using Matlab and compiled as a 'standalone' package. However, it is necessary to have the Matlab Component Runtime (MCR) on your system which is available for download below and requires administrative privileges to install.

Please DO NOT redistribute this software. If you know of someone else that may find this software useful please direct them to this website to obtain their own copy directly. Installation instructions are included in the reference manual.

System Recommendations

  • Windows XP or later
  • Minimum 600 MB hard drive space
  • 1.5 GHz Processor or faster
  • Minimum 1024 x 768 monitor resolution (If you have your monitor set for a higher resolution you might want to change it to this when running SAAS for a larger GUI.)
  • Minimum 1 GB RAM (or more for larger data sets)
  • Read/Write privileges to at least one folder on your computer
  • Administrative privileges during first time installation
