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.

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

• 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

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

• Process and analyse GIS and time series informationProcess and analyse GIS and time series information• Publish selected information (general, drought, Publish selected information (general, drought,

For given scenarios of planned water allocation:

What is the risk of reaching critically low levels in coming dry season?

What is the likelihood of filling the reservoir in the coming wet season?
