Introduction
...
Routed links may gain or lose water due to rainfall, evaporation and groundwater (seepage) as flow does not travel from one end to another instantaneously. You can choose which of these lateral fluxes the ordering system takes into account by enabling the relevant checkbox shown in the node’s feature editor (Figure 1). The data for each of the fluxes is taken from its corresponding item in the hierarchical list. For example, if you enable Use Loss/Gain, Source uses the table specified in Loss/Gain. If you choose Groundwater as one of the fluxes, you must specify a time series for it, which can be imported.
The order coming into the routed link is adjusted to cater for the lateral fluxes over each time-step that the ordered flow spends in the link.

| Note: Changes in link storage volume are not forecasted over the order period, as it does in the storage node. So, where there are significant jumps in the volume ordered, there may be insufficient water stored in the link to achieve the required downstream flow to meet orders. |
Order Crawler Recorder
The Order Crawler Recorder is a new recorder to show all the nodes and links in a network and what their orders and requirements are on a particular date. Available under: Miscellaneous \ Ordering \ Order Crawler. The Order Crawler is a fully interactive zoomable schematic that shows:
- order data for all nodes and links (water users show their requirements)
- the entire network with node locations in the same location as the network
- the minimum order time values (same value as order recorder) e.g. if order travel time is 3 (minimum) to 5 (maximum) days the orders for 3 days out will be shown.
Note: for large networks, it does record a lot of data and is primarily for problem-solving and not intended to always be turned on.
