Thrust 1:
Water Resource Assessment and Planning
This thrust focuses on developing a scientific
understanding of the hydrological cycle (and
inter-linkages) in order to promote systematic water
assessment and planning. The thrust will promote better
understanding of the variability of the quantity and
quality of water available for use and development in
South Africa. Recent changes in national water resources
infrastructure management, the awareness of the poor
state of water resources infrastructure and increased
knowledge of water resource planning needs are expected
to receive attention, through the support of competent
and sustainable solutions. Sound water resource
assessment and planning can only be achieved with
reasonably accurate and consistently recorded and
processed data and information. The thrust will support
the implementation and use of a national water resource
information system.

Programme 1: Catchment data
and information systems |
|
This programme will
support the provisions of Chapter 14 of the
National Water Act, especially Part 2: National
Information Systems on Water Resources. This
programme is focused on supporting the national
initiative for improving the available water
resource information, better management of the
information and improved information dissemination
to stakeholders. It will establish direct linkages
to the national information systems as well as
identifying and resolving water resource
information gaps. In this programme researched
water resource information will be integrated into
the national information system that is being
established by DWAF. The programme will also
support the process of decentralizing identified
water resource data and information from broader
national perspectives to detailed and highly
resolved local and catchment scales. |

Programme 2: Surface water
/ groundwater hydrology |
|
This programme
focuses on developing and utilizing integrated
hydrological approaches in surface and groundwater
assessments, water resource explorations, planning
and management. It will take advantage of gains
made in improved understanding of groundwater and
surface water hydrological processes as well as the
availability of better hydrological data especially
the various forms of more accurate remotely sensed
data with better coverage. Through this programme,
strategic partnerships with international expertise
in both groundwater and surface water hydrological
research will be encouraged to flourish.
Hydrological tools that have been developed in the
past are expected to be upgraded, redeveloped or
replaced by tools that are more suited to the
current data availability, the improved knowledge
and the recent technological advances in
hydrological modelling. |
|
Programme 3: Water resource
planning |
|
This programme will
address water resource planning for the purposes
of improved water allocation, better management of
water use activities and to ensure secure,
sustainable and adequate national water resources.
It is also focused on the development of tools
that will address planning gaps such as the
absence of reliable information in ungauged areas
and the persistent record gaps which exist in
present data sets. The programme will promote a
deliberate shift towards the development of water
systems plans that will benefit from real time,
historic and stochastic data on a countrywide
basis. Impacts of climate change on water
resources and the planning processes will be
accounted for so as to ensure a proactive approach
and allowing for national preparedness.
Integration will also be achieved through aligning
this programme to wider national water resource
planning needs which have to account for other
factors such as national strategic importance,
poverty alleviation, economic benefit, empowerment
and the importance of meeting the Millennium
Development Goals. |
|
Programme 4: Water resource
development |
|
This programme will
improve the understanding of national needs for
water resource development, existing water
resource infrastructure maintenance and
rehabilitation. The equitable allocation and
access challenges and economic growth target of 6%
of GDP per year will require thorough
understanding and assessments of alternative
sources of water. Such sources could be built into
future projections for new water, virtual water,
water transfers be they national or international,
desalinization, etc. The programme will also
promote the integration of social, economic, and
environmental considerations as key components of
sustainable water resource development. Effort
will be applied to the development of solutions
for supporting and complimenting the processes and
strategies pursued by the Water Infrastructure
Agency. |
|
Programme 5: Climate change
and hydroclimatic variability |
|
The goal of this
programme is to better forecast the variability of
rainfall, flow and groundwater recharge. The
ability to forecast at very short time scales (48
hours down to a few hours ahead) would greatly
benefit flood management and disaster mitigation
activities. At longer time scales (e.g.
inter-annual or seasonal scales) the ability would
greatly assist decisions concerning seasonal water
allocation to various users and the environment.
Forecasting models range from the empirical (based
on statistical relationships which use various
oceanic and atmospheric predictors) to the
mechanistic (based on the use of dynamic models
encapsulating best understanding of influential
atmospheric and oceanic processes). This programme
will also seek to improve the understanding of
climate change for the purposes of better
informing the nation on permanent changes of the
climate which require long-term solutions and
mitigation. Through this programme support will be
provided for weather and climate disaster
mitigation programmes at various levels which will
include regional, national, provincial as well as
other more localised scales. |
|
Programme 6: Water resource
quality management |
|
The quality of
water is an important factor in determining the
quantity of water that is potentially available
for productive use. Determining the amount of
water available for different uses is further
complicated by the considerable variation that
exists in quality requirements between and within
different user groups. This programme is aimed at
developing and refining fitness-for-use criteria,
developing the means to monitor and assess water
quality at regional and national levels, improving
the manner in which water quality information is
conveyed and the identification of emerging water
quality issues. The programme also seeks to
investigate and apply water quality control and
mitigation measures. |
