3. Decision
A reasoned choice among alternatives
Definition of a DSS
Computer based systems integrating tools and
databases that assist a decision-maker
in making informed decisions and
analyze consequences.
4. Misconception: A DSS takes decisions
o Using a DSS, a project manager is able to
make rational use of resources without an
in-depth knowledge of modeling techniques
o Provides timely information
o Communicate result to a larger audience
o Open and unbiased working
o Scenario analysis

7. • A river basin is divided into a number of sub-
basins based on the location of hydraulic
structures and hydrological network
• A hydrological model (NAM) is calibrated for
each sub-basin to estimate the hydrological
components (evaporation, rainfall recharge,
overland flow, interflow and base flow) ~ Soul
• An allocation model (MIKE Basin) in
conjunction with hydrological inputs is used
to allocate the available SW and GW ~ Heart
• DSS is used to analyze scenarios ~ Brain
8.
9. Objective
• NAM model provides a conceptual representation
of land phase of hydrological cycle and simulates
rainfall-runoff processes at the catchment scale.
Basic data requirements
• Precipitation time series
• Temperature time series (for snow melt modeling)
• Evapo-transpiration time series
• Observed discharge time series
Basic model outputs
• Catchment runoff
• Subsurface contributions (base flow, interflow)
• Actual evapo-transpiration
• Groundwater recharge and levels
• Soil moisture storage content
