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.

ERROR in WAQ(1) respect to the horizontal surface area of the segment

Hello everybody, 
I am modelling a 3D hydrodynamic and water quality model to an stratified lake. In this way, I am having some issues when executing WAQ(1) with the following statements: 

"Input parameter  nr:    1 is parameter  nr:    1 with ID  : SURF                
 Input parameter  nr:    2 is parameter  nr:    2 with ID  : bottomdept           Input will be given for all    2611224 segments.
 ERROR: Array of character strings too small.
        Use command-line option -cmax to increase the size!
        Minimum size required:    2611247
 ERROR encountered in processing this block ! Total number of constants        :   22 Total number of parameters       :    2 Total number of functions        :    0 Total number of segment functions:    0 ERROR.
Too many and/or invalid data in block   7 !! Check input file !!"


I already know that the input parameter with extention '.srf' is about the horizontal surface area of the segment, wich refers to the computational volumes. Besides that, '.srf' refers to sigma layer as well. In additional, is important to say that my interest is only about the dissolved oxygen.
 I hope that someone can help me to solve this problem.

Regards,Helena.
