Hi,

You can use the reporting tool to export total discharge passing through for a given time period

Hi Hussain,

Can you provide more details on which error you've received or log files if you have them available?

Hi Hussain,

You will have to convert the rainfall file from excel to Mike input format. First convert the rainfall data to dfs0 or dfs2 file depending on the type of data you have, then add this data in the boundary condition under catchment load .

Hi Erik,
You have to specify Pump Curve for all pumps in the definition menu. For this. Once you open pump menu from Epanet>Pumps, select table under pump type and select the Q-H relation and Efficiency curve for the pump. see attachment.

Hi.
If you want different .prf files to be generated , then try breaking the simulation period in smaller time periods . you can use the Hot Start functionality to set up the initial conditions for next simulation. For example,If I have to perform a simulation for 2 days period, then I generally divide it into 2 simulation periods and use the conditions from 1st day simulation and set in the hot start for next day simulation.
Hope I'm clear. let me know if you require further information. You can use Mike Urban manual and read about Hot Start functionality.

Hi,
It's possible to change the network type for all manholes or selected manholes at once. You can use field calculator for this. This works the same way as in ArcMap. follow the below steps.
1. first select the manholes. then open nodes table from MOUSE drop down.
2. select field calculator by clicking on the attribute heading and type 0 to set Null value, 1 for "Waste water", 2 for "Storm water" and 3 for "Combined" in field calculator.

I have added two images for your reference for step 1 and 2.
For future reference, drop down tables in Mike Urban which have only specific values can be correlated with values 0 to n. for example for Nodes status , you can change all manholes status at once by giving 0 to 10 value in field calculator.

Hi,
Yes. it's possible to import Shape file for water meter locations and then add water demand from excel file. Try following steps
1. Import shp for water meter locations with ID as description or MUID. This  way it'll be easy to identify the demands from excel file with water meter location.
2. Open Arcmap layout from Mike Urban and use join/relate functions in ArcGIS to add water demand from excel to demand points. you can use MUID to correlate the tables. you may have to convert excel to csv/dbf format in Arc map to use correlate/join functions.

It'll be easier if you could add demand first with water meter shapefiles, and then import it in mike urban.

Hi Saleem,
Perform the following steps to delineate catchments.
1. First, delineate catchments with manholes on DEM. This can also be done in ArcGIS.
2. Once you have delineated/imported the bigger catchments, Try delineating/breaking them through theissen polygon method with Catch pit layer. This is also done through delineating wizard but the only difference is you have to select the existing catchment layer as boundary polygon.
3. After performing this you have to make some correction in catchments as this will make some gaps in the catchment layer.

Whether you should first delineate catchments with catch pit layer or manhole layer, this depends on how equally distributed your catch pits/manholes are.

Hi,
Perform the following steps.
1. Delineate catchments with Catchpits first and then further delineate them with manholes if water from surface is also entering through manholes in the system.
2. To run the overland flow model, couple the manholes/catchpits with the surface. You can read about all the properties which need to be defined in OF flow model in Collection system manual.
3. To add the boundary condition, you can either add this in 2D overland flow model or with the catchments.
4. Run the project check tool after each steps.

Let me know if you require any more clarifications on this.

Are you able to load ArcGIS through Mike Urban properly. Also check if 3D analyst section in ArcGIS is working properly.
