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.

Observation point for seiches waves

Youngling Posts: 2 Join Date: 3/29/19 Recent Posts

Hi everyone,

 

I'm planning a study on a real lake in Italy and my aim is to study seiches waves. I put 3 observation points on the domain into delft3D to see the history variation of some variables in time in these points but I can't understand how to visualize the results. Is it possible to represent the results in Quickplot or in Matlab? I can't find the file where the program report the results and also in Quickplot there isn't any voice about observation points. Hope someone help me using observation points.

 

Best regards,

Mirko

Hi Mirko,

If you open the trih-****.dat file in Quickplot you should be able to see data from the monitoring points. If there is no data then check your output time is set appropriately.

Cheers,

Richard

Observations of the interactions of large amplitude internal seiches with the sloping boundary of Lake Simcoe, Canada show a pronounced asymmetry between up- and downwelling. Data were obtained during a 42-day period in late summer with an ADCP and an array of four thermistor chains located in a 5 km line at the depths where the thermocline intersects the shallow slope of the lakebed.
