  Q1 Is it possible to import and export Miduss data to Excel?

  Not in 98 version but version 2 allows both single variable and also grid block transfers in and out.

  Q2 One customer suggested that the "98" should be drop from Miduss as it gives the impression that   the program is outdated.

  Version 2 is known simply as "MIDUSS".

  Q3 Currently, Miduss pond outlets are based on orifice discharge and free draining. We should   allow customers to enter their own Stage-discharge (and maybe also Vol-stage) curve if they desire   so that the MIDUSS pond configuration can be made more flexible for other outlet and storage   configurations. In such situations the user is only using the Miduss level-pool routing function.

  Version 1 allows the user to enter values for Stage, Discharge and Volume directly into the grid on the   POND form. This can be rather tedious but is somtimes helped by double clicking on a cell which causes the   two cells above to be extrapolated. One major problem is that if the user employs one of the menu items for   Storage or Outflow control the grid values are overwritten. However, if one avoids using the menu items the   manually entered values are saved in the output file and are automatically recovered in automatic mode. In   version 2 it will be a simple matter to export or import all or part of the H-Q-V grid between MIDUSS and   EXCEL.

  Q4 I want to model a pond which has an irregular shape. I can get data from an AutoCAD drawing.   Do I have to calculate the storage volumes by hand and enter them in the 'Volume' column of the   grid?

 You can do this but there is an easier way that you can try. It can be shown that the equivalent aspect ratio R   = length/breadth is related to the perimeter P and area A of any plan section of the pond (i.e. base, top water   level or in between). The relationship is given by:

      f(R) = 4R + 4/R + 8 = P^2/A

 You can get values of P and A at the base of the pond and work out the corresponding value of R. Then use   the Geometry|Rectangular menu command with this value of R as the aspect ratio for the base. MIDUSS will   work out the reducing aspect ratio at higher elevations. At elevations where the sideslope changes fairly   abruptly you can check the value or R from data taken from the AutoCAD drawing or contour plan and enter a   preferred value o aspect ratio.  You can even model multi-cell ponds in this way. At elevations below the berm   which forms the cells the value of R will be quite large (e.g. 6 or even 10). Above the top of the berm, the   aspect ratio will reduce due to the abrupt reduction of the perimeter P.
