DBH model is unique

● Use nontraditional datasets from remote sensing, in situ observation, and surveys

● Can model the connections among hydrology, the rest of the earth systems and human society.

 

DBH model gives the new direction of hydrological modeling

● The first generation hydrological model was based on statistical relationship or integration in a lumped/fake-distributed way.

● The second generation model, distributed model, solve the differential equation on discretized grids.

● The latest new (third) generation models, DBH model, used modern theories relating biosphere to provide a more realistic description of land surface hydrology. It incorporates the advanced schemes to understand the response of hydrological cycle to the change of biosphere, human society and climate system.

 

DBH model is versatile

● Can be linked to ESRI's ArcView for advanced GIS applications

● Support diverse global datasets

● Can simulate most of the Earth’s land with global datasets

 

DBH model is easy to use

● Links to original data rather than importing the data

● Allows you to update your original data

● Has automatic data and model verification routines

 

DBH model system includes advanced module for

● Manipulating time varying data

● Model calibration

● Mass and energy balance analysis
