intro story 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.

file.eva error in reading the file of precipitation

Dear all,
I am modeling a wetland and need to add the precipitation file. As prescribed by the manual, I inserted four columns for time, precipitation, evaporation and rain temperature, separated by one blank (see the attached file). For evaporation, I inserted the value of -999.0, as I want DELFT to calculate it internally.
When running the simulation, I receive the message of error in reading the file. What am I doing wrong? Is it possible that maybe I am missing some flags in the "additional parameters" section? For now, the only related additional parameter is Maseva = #Y#

Thank you,
