Overview

The main objectives of this consultancy were to enlarge and improve the existing models for the Orange-Senqu Basin, so that they incorporated all of the essential components in the four Basin States and are accepted by each Basin State.
These models must be capable of providing the current and likely future information needs of ORASECOM. This will involve being able to assess the implications of additional water resource development options to achieve water security in each Basin State – including possible changes to operating rules for water supply and storage infrastructure.

This will ensure that ORASECOM is able to demonstrate that its operations are aligned with the principles embodied in the SADC Water Protocol.

The Project included 6 work packages that are described below (for more information about the work packages, please click on the title):

WP 1: Development of Integrated Orange-Senqu River Basin Model

Objectives: To enlarge and improve existing models so that they incorporate all essential components in all four States and are accepted by each State

WP 2: Updating and Extension of Orange-Senqu Hydrology

Objectives: Updating of hydrological data, hands-on capacity building in each basin state for generation of reliable hydrological data including the evaluation of national databases.

WP 3: Preparation and development of integrated water resources  quality management plan

Objectives: Build on Phase 1 initial assessment to propose water quality management plan, based on monitoring of agreed water quality variables at selected key points

WP 4: Assessment of global climate change

Objectives: Several objectives leading to assessment of adaptation needs

WP 5: Assessment of Environmental Requirements

Objectives: Several objectives leading to management and monitoring
system responsive to environmental flow allocation

WP 6: Water Demand management in irrigation sector

Objectives: To arrive at recommendations on best management practices in
irrigation sector and enhanced productive use of water
