Recommend that in existing 1d_bc layers to rename attribute “Ignore” to “Flags” and set Flags as a Char(6) field, then clear all “F” values in the Flags attribute.

Added in new map output type “Z1” for NSW flood hazard output. Value of 1 is low hazard, 2 transitional and 3 high.
Parallel channel calculations for a composite cross-section now split up based on changes in material values when using materials for a 1D cross-section. This removes the problem when two adjacent materials have the same Manning’s n value, which previously would have treated the two parallel sections as one. Not backward compatible.
U/S and D/S inverts for non-sloping 1D channels now output to 1d_nwk check file as the bed level of the section.

Incorporated 2D HS boundary (4 columns) into .csv format for bc dbase.
New 1D time-series output as _TS.mif containing heads, flows and velocities for up to the first 249 output times. Excellent for graphing results in MapInfo using the Graph Window.
Included new bc_dbase column names: “Column 1”, “Column 2”, “Column 3”, “Add Col 1”, “Mult Col 2”, “Add Col 2”.

Fixed incorrect output in 2d_bc_tables_check.csv file of from/to cells for a boundary line.
Fixed bug that incorrectly accumulated 2d_bc HT boundaries (eg. putting a storm surge on a normal tide). Only applies to GIS 2d_bc input (not original fixed field).
Fixed bug that didn’t correctly set alphanumeric ID attribute of nodes or channels for 1d_mm output.

Added in “A” flag for XZ tables that adds the value in Column 5 to the Z value (useful for modelling rails, siltation, etc). Values can be negative.
Put in more checks on reading 1d_ta tables, particularly CS tables.
Corrected bug that output dangling elevation checks as negative instead of positive elevation.

Increased maximum number of points in a Zline layer to 50,000.

Added “*” flag to water level output in .eof file when have fallen below -0.1m to warn that mass loss may be occurring.
|
2003-04-AB
|
A “*” (later changed to a “L” in Build 2003-07-AF) flag in the second position after velocity or flow values in the .eof file indicates the velocity rate limit factor was applied – structures and non-inertial channels only. Stuctures where this is happening continuously should be checked.
|
2003-04-AB
|
Added in dry check for upstream end of a 1d_nwk "S" channel for upstream controlled flow calcs. If dry, flags after velocity/flow in .eof file are “SE” standing for "S" channel that is "E"mpty.

Now sets the initial water levels at 1D HX nodes to the initial water levels of the connected 2D cells.

Improved culvert stability when close to zero head drop - this may cause slightly different behaviour in culverts in this situation
|

|
Included empty 2d_sa .mif file when using Write Empty MI Files.
|
2003-03-AE
|
Corrected 1d_ta empty file to adjust for change in format introduced in 2003-03-AA.
|

Changed the automatic height of a weir specified using the width attribute in the 1d_nwk layer, from 100m to 5m – if the weir’s storage is applied at the nodes, this may effect the vertical increment for calculating the NA table which may effect results very slightly. If water level exceedance (instability) warnings occur use Depth Limit Factor to allow water levels to go above weir, or create a cross-section for the weir with a greater depth.

|
Added minimum/maximum output to Energy SMS .dat files.
|
2003-03-AE
|
Added 99999.1 time output to _h.dat files to show the simulation time when the peak occurred.
|
2003-03-AE
|
New “_ TUFLOW Simulations.log” file to log start and finish of TUFLOW runs.
|

New 2D "SH" boundary primarily for pumping water from 2D domains to elsewhere in the model or out of the system. A 2D SH can be on its own (ie. unconnected so that water will enter/leave the system with gain/loss of mass); be connected using the new “SC” (Source to source Connection) 2d_bc line to either a 1D node or another 2D cell (water in/out of SH will end up out/in 1D node/other 2D cell). SH can be spread over more than one cell, however, the same flow will apply to all cells – the total flow is NOT equally distributed over the cells. The flow (source) in each cell is interpolated from a S vs H curve extracted from the bc database, where H is the water level in the cell. If the cell is dry (ie. below wet/dry depth), no flow in/out occurs.

Changed check for automatic 1D HX assignments (connected to 2D SX conditions) that fall on a 1D Q boundary from a WARNING to an ERROR.
|
2003-03-AD
|
Added checks for 1D QX conditions that fall on a 1D H condition – these are not compatible and are now detected as an ERROR.
|
2003-03-AC
|
Changed .2dm output to allow for huge elevations, which caused sms_to_mif.exe to crash.
|
2003-03-AB
|
Further improvements to steep long culverts – this may change results slightly.
|
2003-03-AA
|
Revised relative resistance (RR) formulation for 1D XZ cross-sections. RR value now applies centrally (to mid-way either side of XZ point - rather than from one XZ point to the next.). This removes the uncertainty over between which two XZ points the RR value applies.
