Thomas, >1. What does the table labled "Waterbody 1 Bathymetry [B], m" represent? The B variable is the cell width. >2. What is the "Water Surface [Z],". I am getting a value of -0.6 under a number 4. The number 4 is the same as my most downstream Segment Number. My water surface elevations are in the 120 m range, so I am not sure what the -.6 is. The Z variable corresponds to the distance from the top of the top most active layer (also called the KT layer) to the water surface. Positive Z is downwards, and negative Z is upwards. >3. I am noticing that in the table under "Waterbody 1 Initial Volume", that KT has been assigned to layer 4. Are the >elevations in this table the top of layer elevations? If so, layer 4 goes from 117.84 to 119.87, but my starting water >surface elevation "ELWS" is 121.92, which should put KT into layer 2 which runs from 121.90 to 123.93. I have tried >different values of ELWS and I can see KT jumping to different layers, but I can't see how it is selecting the layer >for KT. Yes, the elevations are the top of layer elevations. Also, even though the top most active layer (KT) may be layer 4, if the water surface is above the top of layer 4, the volume of the these layers are incorporated into to the top most active layer. The selection of the KT layer depends on the slope of the grid, the amount of water in a layer, water surface and the deepest layer in a specific branch where the water surface resides. Hope this helps, chris
