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.

Dear all,

When i run the in python (2.7.13 and 3.4, in 64bits)with VS 2015 (With the C++ update) and Interl Visual Fortran Composer XE 2013, gives the following error:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe1 in position 33: ordinal not in range (128)

This is for mi professional pratice and i need make a model in Deft3d (4.03.00) , but i can't compiled.
