intro story Lake

Lake

Lakes and reservoirs are important resources for communities around the globe. They provide food, drinking and irrigation water and can also offer spots for recreation. Under certain conditions lakes can also represent a threat for local communities, such as flooding or limnic eruptions. The ecological state of shallow lakes may be hampered by suspended sediments due to wind driven currents and waves. In deep lakes, stratification can cause undesirable anoxic conditions in the deeper areas. Understanding these systems is crucial to enable a sound management of these water bodies.

 
Delft3D is the state-of-the-art modelling framework for hydrodynamics, water quality, ecology, waves and morphology.
 
Here, in this space, we share knowledge & experiences, and discuss issues related to modelling of lakes.

Delft Dashboard tidemodels

Hello, I have recently started working with Delft Dashboard to generate files for Delft3D flow/waves however when I click on 'make boundary conditions' in Model Maker Quick Mode, MATLAB gives the following error:
Error using nc_varget_java (line 31)
Could not open 'https://opendap.deltares.nl/thredds/catalog/opendap/deltares/delftdashboard/tidemodels/tpxo72.nc' with java backend.
I have updated the SVN to ensure that I have the most up-to-date version of Delft Dashboard. Could something be wrong with the xml file or links provided in the xml file? or could the websites be down?  I've added the contents of the xml file in case something in it needs editing.<?xml version="1.0"?>

Hi Lesley, 

You probably already have an answer for to this. The server for the tide database was down a couple weeks ago. I dropped Delft an email and they have since fixed the issue, but you do need to update (redownload from the SVN) your dashboard from OpenEarth tools. 
Hope this helps, Christian

Maybe it is because of network problem. I tried both Txpo8.0 and 7.2 today in Dashboard, and accessed both successfully.

Maybe just try another time?

Hi Raymond Rios,

Today (03/18/2021) I accessed the Delft Dashboard Tide Models however, this error shows:
opendap.dap.DAP2Exception: Method failed:HTTP/1.1 503 Service Temporarily Unavailable on URL= http://opendap.deltares.nl/thredds/dodsC/opendap/deltares/delftdashboard/tidemodels/tpxo62.nc.dds

When was the last time you accessed Delft Dashboard Tide Models? Can you access it now?

Your help would be very much appreciated.

I have found that sometimes waiting a while (less then a day tho) fixes the connection errors.Also, have you tried using different network?

Make sure that DelftDashboard code is updated using SVN. Click the update repository button. If it fails/times out, please “clean up” the directory with your svn tool, and try again until you get a success message.

Regards
