Overview The CMSS model uses land use and nutrient generation data to predict the nutrient load (or load of any other pollutant) reaching the waterway of a catchment. Land management data are then incorporated into the model to predict the impact of various land use and/or land management practices on pollutant loads. The model can also assess the cost of various practices, making this an ideal tool for catchment managers. WinCMSS WinCMSS is an implementation of CMSS in a Windows Environment. It contains the same models and has the same data requirements of CMSS, but provides extra mapping and reporting features. It also takes advantage of the standard Windows interface such as toolbars, drop down menus and multiple windows to enable easy navigation around the program. Features Some of the features of WinCMSS are: Multiple windows that can be opened
simultaneously, eg catchment views, mapping unit views, results in text, graph or map form;
Modification of catchment data is interactive; Most of the setup of applications is automatic; Data input is through standard Windows
dialog boxes; Catchment regions, subcatchments and
mapping units can be manipulated with the mouse and land use information and routing links are easily editable; and
Utilities for converting DOS CMSS applications and maps to WinCMSS.
Data Requirements The model requires the following information to predict loads for the existing (or base) catchment: a subcatchment map; a land use map with land uses differentiated
by nutrient generating capacity; and nutrient generation rates for these land uses.

In addition, data on land management practices and changes in land use are required to assess the change in pollutant load that may result from the implementation of these. Policies Land use policies describe changes in land use for both diffuse and point source land uses. Land use policies can be very complex, specifying where the change can occur (on land of a particular slope class, for example), how much land is converted and the expected compliance. Land management policies describe the adoption of land management practices (for example, installation of wastewater ponds below dairy sheds). Policy sets can be created that enable groups of policies to be run simultaneously.

Results WinCMSS has major advantages over CMSS in reporting results. Results can be displayed as spreadsheets, graphs and maps that can be printed, saved to a file or imported into word processing applications. Spreadsheets are fully configurable. Data
from any model run can be included in spreadsheet reports and data from different model runs can be compared.
Graphs can display results of one to five model runs. Graphs are fully configurable, including options for log axis, gridlines, bar widths and colours, absolute or percentage plots and displaying uncertainties.
Estimates of result errors are generated using input parameter uncertainties.
In maps, subcatchments are colour coded to indicate the magnitude of load exported or the percentage change in load between model runs.
Availability WinCMSS is available for download from the Catchment Modelling toolkit website http://www.toolkit.net.au. The User Guide, CMSS Tutorial Book, and NEXSYS expert system for estimating nutrient generation rates are also available.
