PROPOSED BASIN STUDY
PROPOSED BASIN STUDY
Period/phases of the Consultancy
Phase I-
Development of the comprehensive model/ suite of
models .-2 year
Phase II-
Maintenance, updating and Running of the models in
real time during warranty period.-2 year
Scope of Consultancy
Phase-1 (Development Phase- 2 years)
Understand the catchment yield and how this varies in time and space,
particularly in response to climate variability: seasonally, inter-annually, and
inter-decadally.
Estimate the relative contributions of individual catchments to water
availability over a much larger region, e.g. valley or basins scale.
Estimate how this catchment yield and water availability might change
overtime in response to changes in the catchment, such as increasing
development of farm dams, or changes inland-use and land management.
Development of the comprehensive model/ suite of models for, creation of
basin wise plan, including integration of models with input data, creation of
dissemination web based GIS portal and dissemination of model output in
defined platform.
Scenario analysis with climate change impacts for present as well as future
Development of Dashboard for IWRM plan and its linkage with existing
portals like WRIS, NWIC etc.
Scope of Consultancy
Phase-2 (Warranty period- 2 years)
1. Updating models and data as and when required.
2.
Addressing problems faced by stakeholders.
3.
Debugging of models and dashboards
4.
Ensure dissemination of outputs/results to all stakeholders and updation of
dashboards if needed.
5. Ensure linkages with existing portals such as WRIS, NWIC etc and with the
micro models developed by states in that basin.
Objectives
To prepare a long-term Integrated Water Resource Management
(IWRM) plan for the river basins, taking into account the State's
socioeconomic development plan;
To develop both demand management and supply management
options, and encourage water-use efficiency through non-
regulatory and regulatory mechanisms, particularly to increase
efficiency in irrigated and dry land area and engaging the
community in the management of the basin's resources,
elaborate, monitor and review the River Basin Management Plan
so as to;
Develop, and update a Water Master Plan through public
information and participation;
Strategic planning in setting long-term goals for water
management in the basins covering issues, priorities,
management actions, costs and benefits, and risk assessment.
Objectives
Identification of existing and Potential problems in the
basins.
Facilitation for the formulation of planning and
management strategies using the information generated
by the Models.
Multi-scale environment flow assessment
Formulating framework for climate change impact
assessment on water resources and adaptation option
studies in future
Scenario generation
Generating problem specific scenarios
Capacity building of state government and CWC officials
Learning on the job while working with models of
their own
basin as well as bottom up approach to
planning and management in the real sense
To establish multi stakeholder engagement processes for
strategic basin planning
Benefits/Outcomes
Scenarios based on varying efficiencies across sectors, including
agriculture water use and industrial water use.
Assessment of point and non-point source pollution.
Assessment of the
Impacts
Of climate change
on hydrologic extremes of
floods and droughts in terms of likely changes in frequencies and
magnitudes
Assessment of
System performance in terms of implications on multi-
reservoir systems operation including implications on water sharing
among states
Options
for inter-sectoral water allocations, long term and over-year
reservoir operating policies, enhancing water use efficiencies, possible
decreases in water demands by adjustments of cropping patterns,
conjunctive use of surface and ground waters,
enhancing recharge to
ground water through artificial recharge,
modifications in design
requirements of hydraulic structures, change in irrigation practices,
Ecological Management Practices (EMP) for sustainable development
and any other innovative adaptive responses
