Background

The Farm Dam Plugin was initially developed by Sinclair Knight Merz (SKM) and the Western Australian Department of Water (DoW), with support from the National Water Commission (NWC). Now the functionality of this plugin is moved to the Core of the Source, and the user can directly use its functionality without the farm dam plugin.  Farm dams functionality in Source is designed to simulate the impact of farm dams on streamflow at a sub-catchment scale. For each farm dam, the Source conducts a water balance, including inflows, rainfall, evaporation, seepage, water usage (demand), and overflow (spill) components (Figure 1) in each time step. This means that, for each time step (e.g., a day), each water balance component is accounted for in Source for every farm dam modelled. For more information on the initial farm dam models, SKM has produced a series of project reports available upon request from the Department of Water. These reports include:

• User requirements report (SKM, 2012);
• Systems design report for the planning component of the tool (SKM, 2012c);
• Model implementation report (SKM, 2012d); and
• User manual (SKM, 2012e).
