Revision Level	1.0

In addition to a number of bug fixes (please consult the on-line   PROBLEM REPORTING SYSTEM
for an overview) the following new features are available in R5.1:

1. A new improved network display indicating the node coordinates: The name of the node is drawn in a small box if the mouse is moved on top of a Node symbol in the river graph.

2. Graphical node positioning and reach definition: A user can now set the position in grid coordinates of a node through a graphical interface. While viewing the specific settings of an individual node the EDIT-button above the image of the river network become active and opens a popup window viewing a larger version of the graph. A circle around the node marks the current node position. The new position of that node can be set by moving the red dot ontop of the graph to the new position of taht node and pressing the SAVE button.

3. REACH Editor: In the "add reach" - function a graphical component has been added now as well. In addition to the selection of head and tail nodes through it's name, it is possible to select them by clicking on a node in the graphical representation of the river network. A red circle is drawn around the selected had node, a green circle marks the selected tail node. Pressing save will make the selection permanent and draw the reach.

4. SPILL scenarios are re-implemented independently of WRM scenarios;

5. RRM re-implementation: the rainfall-runoff model has been re-implemented to use Descriptors and the Java based editor for its parameter editing. This provide a built-in explanation for every parameter, as well as optional default valuess and a symbolic definition as well as allowable ranges to simplify editing a scenario.

   As an ASP companion product, the automatic calibration system RRMCAL can now import RRM scenarios for calibration, and export RRM scenarios for further analysis with the RRM system.
