Error when calculating subbasin parameters parameters

[jmjvlc]

Hi all,

I was wondering if anybody had the same problem as me or know how to
solve it.

I have created a model in which I provide my own stream network and
subwatershed division. I could run the model succesfully.

However the DEM I was using wasn't fine enough (it was 671x671 m
cellsize). Now I'm trying to change it with another DEM with a higher
resolution (25x25 m). When delineating the watershed, after pressing
the "calculate subbasin parameters" button I get an error message:

Error number: 13
Error message: conversion from string"NoData" to type 'Double' is not
valid.
Module name: mSWFlow
Function name: Setparameters
Procedure (error line or description): Set pHEPtColl=PHEF.ShapeCopy
GRIDCODE=21

I already checked that all layers are the same resolution and they are
all projected in the same reference system.

Does anybody have any idea about how to solve this problem?

Thanks all,

I am having the same issue. Seeing as this was posted 2 years ago, did you ever figure out the solution?

Dear

I am little confused when I read the ArcSWAT Documentation_2012.pdf. In this manual Section 7 page no. 131. First I defined Weather Generator Data and remaining data like Rainfall data, Temp data, Relative humidity, Wind and Solar data files as using example datasets. After Weather Stations, next tab is Write SWAT Input Tables. In the Write Database Tables Sub basin Snow Data onwards upto Master Watershed File are incomplete.

Kindly suggest  me whether I should create first these above mentioned files and if then where should I keep those files for the successful Write Database Tables.

Hi,

I am also having Error 13 and quite clueless on how to fix it. If somebody here figured the solution, I would be more than glad to read it.

First should check the DEM data and make sure NO missing data within the watershed. Apparently, the ArcSWAT doesn't check if current value is NoData. The error only come out when it's trying to convent NoData to a double.

Hope helps.

Dear SWAT users,

I am getting following during subbasin parameter calculation:

object reference not set to an instance of an object ,

error at line number :153,

 error in cmdCalSubbasinParam in arcswat

  I am uisng arcswat 2009.

If anybody has idea ,please help me.

the problem i have is as below in trying to use arcswat at point of calculating subbain paramters
 i got the same problem as below and attached. please what is the way out
"Conversion from string "RGB" to type 'Double' is not valid." in line 13
and i can't just go beyond this point.

attached is detailed as captured above,
many thanks

Apparently your grid has color bands rather than the needed data (elevations, land use, or soils).  You should convert the grids so its cells represent the data you need.

Error Number 13, usually happens when your DEM file and your predefined shapefiles don't have the same projection.

I solved that problem by using the same coordinate system for DEM (raster), subbasin (shapefile), and stream (shapefile) files. It should be projected coordinate system.

I can confirm Fariborz statement. All layers (DEM, userWatershead, userStreams) must have the same projection.
