| 12 | // Update History | ||
| 13 | // ============== | ||
| 14 | // Build 5.1.007: | ||
| 15 | // - Mass balances modified to to correctly handle negative external inflows. | ||
| 16 | // - Volume from minimum surface area at nodes included in mass balances. | ||
| 17 | // Build 5.1.008: | ||
| 18 | // - massbal_updateRunoffTotals() modified. | ||
| 19 | // - LID drain flows and returned outfall flows added to components of | ||
| 20 | // runoff mass balance. | ||
| 21 | // - Seepage pollutant loss added into mass balances. | ||
| 22 | // Build 5.1.010: | ||
| 23 | // - Remaining pollutant mass in "dry" elements now added to final storage. | ||
| 24 | // Build 5.1.011: | ||
| 25 | // - Final stored pollutant mass in links ignored for Steady Flow routing. | ||
| 26 | // Build 5.1.012: | ||
| 27 | // - Terminal storage nodes no longer treated as non-storage terminal | ||
| 28 | // nodes are when updating total outflow volume. | ||
| 29 | // Build 5.1.013: | ||
| 30 | // - Volume from MinSurfArea no longer included in initial & final storage. | ||
