• ABCDE+F framework for basin water management

• Integrated Models• Integrating Models into decision making

Overview

ABCDE+F Framework for analysis of water management (Perry. 2013)

A. Accounting for the available resources B. Bargaining through political process to determine priorities and

allocations C. Codification of the agreed priorities and allocations into rules,

statutes and laws D. Delegation of implementation to appropriate institutions and agencies E. Engineering to deliver the agreed services F. Feedback or the cycle of policy and performance adjustment for

elements A to E.

ABCDE+F Framework for analysis of water management (Perry. 2013):

A. Accounting for the available resources B. Bargaining through political process to determine priorities and

allocations C. Codification of the agreed priorities and allocations into rules,

statutes and laws D. Delegation of implementation to appropriate institutions and agencies E. Engineering to create the necessary infrastructure to deliver the

agreed services F. Feedback or the cycle of policy and performance adjustment for

elements A to E.Understanding use and users is vital

Need to know real objective(s)

Water Accounting about availability• Where it is and in which quantities ? • In what quality• How it is being used where water

goes!

• Integrated use of all types of water• Including use by Ecosystems

Water Accounting

WATER ACCOUNTING +• Tracks water depletions rather

than withdrawals and goes beyond flow and run-off accounting

• Provides consistent and coherent data sets that integrate hydrological processes with water management and the services and benefits from water consumption

BARGAINING• Is about allocating among users, seeking to

meet their needs in terms of:– quality, quantity, and – when and where

• deciding on how water will be used in future– Models enable stakeholders to explore and

debate how water can be used

CODIFICATION

• Translates water allocation to codes of conduct for stakeholders in terms of water use and return flows

• Agreements on tariff, penalties, audit, etc

• Determines needs for physical monitoring at key locations (How much, When, Where)

DELEGATION

• AUTHORIZING various levels of management– From regional to national to local operators

• All stakeholders must be represented in water management decisions

ENGINEERING

• Hardware – structures• Involve combinations of basin hydrology

models and detailed hydraulic models of flood plains and structures

FEED BACK• Back to water

accounting to determine if planned allocation really happening!

INTEGRATED BASIN TOOLS TO ENHANCE EFFICIENCY, PRODUCTIVITY, AND RESILIENCE

• Data is only useful if it is used• Models use data to enable new insights• ABCDE+F provides a framework to integrate

models in the process of basin management and operations

Models are only tru

ly useful if integrated in

decision making processe
