Misconception: A DSS takes decisions ---

(No)----------------------------------------------------------------------------------------------------------------------------------------

--------

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 larger audience

o Open and unbiased working

• 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

Seasonal Planning

• The likelihood of filling the Hirakud reservoir during the current or next monsoon and the risk of having insufficient water for the users at the end of a dry season.

Cropping pattern

Scenario 1: Reduce the area of paddy during Rabi (More Pulse and Maize)

Scenario 2: Short duration Paddy and Pulses (conjunctive use)

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?

Scenario I: no restriction on SW use Scenario II: limited SW abstraction by head

and middle section users
