Attention

Tip

! can be used to indicate comments in the file. Comments are not read by the programme so they can be used by the user to provide notes for their interpretation of the contents. This is strongly recommended.

## 4.2.8.1. Day Light Savings (DLS)¶

The dates for DLS normally vary for each year and country as they are often associated with a specific set of Sunday mornings at the beginning of summer and autumn. Note it is important to remember leap years. You can check http://www.timeanddate.com/time/dst/ for your city.

Tip

If DLS does not occur give a start and end day immediately after it. Make certain the dummy dates are correct for the hemisphere

• For northern hemisphere, use: 180 181
• For southern hemisphere, use:  365 1
Example when running multiple years (in this case 2008 and 2009 in Canada):
Year start of daylight savings end of daylight savings
2008 170 240
2009 172 242

## 4.2.8.2. Grid Connections (water flow between grids)¶

Caution

This section gives an example of water flow between grids, calculated based on the relative elevation of the grids and length of the connecting surface between adjacent grids. For the square grids in the figure, water flow is assumed to be zero between diagonally adjacent grids, as the length of connecting surface linking the grids is very small. Model grids need not be square or the same size.

The table gives example values for the grid connections part of SUEWS_SiteSelect.txt for the grids shown in the figure. For each row, only water flowing out of the current grid is entered (e.g. water flows from 234 to 236 and 237, with a larger proportion of water flowing to 237 because of the greater length of connecting surface between 234 and 237 than between 234 and 236. No water is assumed to flow between 234 and 233 or 235 because there is no elevation difference between these grids. Grids 234 and 238 are at the same elevation and only connect at a point, so no water flows between them. Water enters grid 234 from grids 230, 231 and 232 as these are more elevated.

Note

Arrows indicate the water flow in to and out of grid 234, but note that only only water flowing out of each grid is entered in SUEWS_SiteSelect.txt
