Details of the Precipitation-Runoff Modeling System Soil Zone.

The Precipitation-Runoff Modeling System (PRMS) is a deterministic, distributed-parameter, physical process based modeling system developed to evaluate the response of various combinations of climate and land use on streamflow and general watershed hydrology. The primary objectives are:

  1. simulate hydrologic processes including evaporation, transpiration, runoff, infiltration, and interflow as determined by the energy and water budgets of the plant canopy, snowpack, and soil zone on the basis of distributed climate information (temperature, precipitation, and solar radiation);
  2. simulate hydrologic water budgets at the watershed scale for temporal scales ranging from days to centuries;
  3. integrate PRMS with other models used for natural-resource management or with models from other scientific disciplines; 
  4. provide a modular design that allows for selection of alternative hydrologic-process algorithms from the standard PRMS module library.

Support for PRMS

Support is provided for correcting bugs and clarification of how the code is intended to work. Only limited assistance can be provided for applying PRMS in specific studies.

Before contacting us for support, please:

  1. Make sure that you have downloaded the most current version of PRMS (available above).
  2. Run the model in "command line mode" (see the example problems included in the download on how to do this) and correct any issues that are identified by either error or warning messages.
  3. If you were unable to get rid of any messages, capture (screen grabs are best) them in their entirety.
  4. Describe the action that seems to have triggered the problem (ie "started crashing when I try to load a new data file").

How to Cite PRMS

This USGS software has two citations associated with it.

  1. The report citation is for the original report or article documenting the underlying theory, methods, instructions, and (or) applications at the time the initial version of the software was released. This digital object identifier (DOI) is for the report.
  2. The software release citation is for the software/code itself (now referred to by USGS as a "Software Release") and references a specific version of the code and associated release date. This DOI links to the code.

In instances where an author is citing use of this software, it would be appropriate to cite both the report documenting the code and the specific software release version that was used.
