BHM is a HBV model based hydrological model developed by Beray Engineering. Catchment calibration is made with BHM program which was developed to be able to implement this model. Program is used for flow estimation calculation in a certain catchment. Project file of the analyzed catchment might be integrated into MARNAS system.

BHM attributes

• Adding – subtracting elevation regions
• Adding – subtracting vegetation regions
• Adding – subtracting lake regions
• Independent calculation of East – West, North and South regions
• Catchment calibration with MonteCarlo Simulation
• Numerical and graphical display of the results
• Calculation of error ratios between observed and estimated flow
• Integration possibility of analyzed and saved projects into MARNAS system
