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.

Z coordinates in Particle tracking usging Z-model

Hi,I am running a particle tracking based on a Z-model hydrodynamics. I have issues with the vertical coordinates of my particles. In the results of my PART simulation, the value near the water surface would be something like -70 while the value at the bottom is 1.02 something (When I try with release in different layers, these values are the initial starting points of the particles at time step 1). My idea is that the Z coordinate be the depth under the water surface. I don't know how these Z values could be interpreted as the bathymetry is above 100 meters but at where I release the particles, the water depth is only around 40 meters. Thanks in advance.

The new implementations were validated by using the output of the Z-coordinate Massachusetts Institute of Technology these values are the initial starting points of the particles at time step 1, doesn't work.. myprepaidcenter
