2. Project Management
For much of my career I have been managing projects or setting up and supervising them. I was also
the motivating force behind, and a founder Partner of, Water Resource Associates LLP in 1992: a
company which has gone on to work in over 100 countries. I am still a Partner in this company
Summary
When I worked for a Water Authority in the UK
in the 1970s I became project manager for flood
forecasting development. When I moved to a
firm of consultants I was also managing projects
in the UK. From 1984 to 1991 I was managing
two projects for the World Meteorological
Organisation, one in Niger and one in Indonesia.
From 1992 to 1993 I was deputy team leader of a
multi-disciplinary project in Botswana. From
1994 to 2007 I set up and supervised projects for
the European Union and the French government
as part of the Middle-East Peace Process. During
this period as I had to make frequent visits to the
region I was not able to manage projects. Since
then I have managed a three country project in
Southern Africa.
Hippotami in the Okavango Delta
Projects Managed
• HYDORNIGER, management of a flow forecasting system for Niger River Basin. The project
was transboundary and established a satellite based flow forecasting covering 9 countries of
West Africa.
• Indonesia, managing a pilot flow forecasting system. The system was based on radio
transmission of data to two operational centres.
• Botswana, deputy team leader for project reviewing Okavango delta proposals. The team
reviewed proposals to modify river channels in the Okavango Delta, a Ramsar recognised
site, and developed a viable alternative.
• Middle-East, setting up and supervising projects for the EU. Over the period 1994 to 2007 I
set up and supervised two multi-million Euro project for European Union. The projects were
on hydrometric data collection and on waste water re-use and worked with Israeli, Jordanian
and Palestinian organisations.
• Middle-East, setting up an environmental monitoring project for the French government.
The project’s aim was to monitor water quality in real-time and transmit warnings of
potential pollution incidents.
• Southern Africa, team leader for a three-country water management project. The three-
country project (Republic of South Africa, Swaziland and Mozambique) developed a
methodology to optimise the use of reservoirs in the Incomati and Maputo river basins.

3. Climate Change
Climate change is one of the defining factors of our age. Projections suggest there could be major
changes to patterns of temperature and precipitation. These changes in turn could lead to severe
droughts and floods more frequently than in the past.
Summary
I first got involved with climate change in 1981 during a study of Libyan agriculture. In 1998 I carried
out the first major analysis of climate change impact for Severn-Tent Water Authority, one of the
UK's largest. Since then I have analysed impact in Asia, the Middle East, Europe, Pacific Ocean and
Africa. I am also the author of the web site www.climatedata.info.
Countries of Recent Experience
• Albania. Assessing impact of climate change on river basin management.
• Bangladesh. Estimating impact of climate change on sea levels and rainfall intensity for
climate resilient infrastructure.
• Samoa. Developing a methodology for rural road flood resilience taking account of climate
change and orographic effects on rainfall.
• Vanuatu, flood estimation for rural roads.
• Mekong, flood and drought sequences. Calibrating a hydrological model of the Mekong river
system including the Tonle Sap Lake and superimposing the effects of climate change. This
led to the development of vulnerability maps for the area around the lake.
• Cambodia, rural flooding and droughts. Downloading and analysing climate change
scenarios for three provinces of North-East Cambodia.
• Tagus (Spain/Portugal), water resources and hydropower
• Malaysia, potential impact on hydropower
• Turkey, impact on winter runoff.
• Zambia, changed seasonal temperature and rain patterns
• Kagera basin, water resources availability
• African Great Lakes, changes in water temperature and impact on fisheries.

4. Hydrological Modelling
Hydrological modelling is a powerful tool. It can be used with long-term rainfall and climate
data to extend flow records and with projections to estimate climate change impact
Summary
I developed the HYSIM hydrological model in the
UK. Since then it has been used worldwide by
me, fellow hydrologist in Water Resource
Associates and by others. It has been bought for
all regional offices of the UK Environment
Agencies, many Water Authorities and firms of
Consultants. It has been used by Universities in
the Europe and Asia for climate change impact
studies and for training.
The model has a high degree of physical realism
for both the hydrological and hydraulic
components.

Basins where HYSIM has been used recently (in descending order of catchment size)
• Mekong (China, Laos, Thailand, Cambodia, Vietnam, 795,000 km2
)
• Tagus (Portugal and Spain, 81,300 km2
)
• Yesilirmak (Turkey, 37,523 km2
)
• Upper Rajang (Malaysia, 21,273 km2
)
• Pursat (Cambodia, 4,525 km2
)
• Precana (Portugal, 608 km2
)
• Blythe (UK, 197 km2
)
• Cwellyn (Wales, 21.2 km2
)
• Pago Stream (US Samoa, 1.52 km2
)
All the simulations were at a daily time-step except for the Upper Rajang (hourly) and Pago Stream
(15-minute)

5. Water Resources
With growing populations and the impact of climate change, the development and management of
water resources is becoming more critical.
Summary
In the course of my career the
emphasis in water resources
planning has gone from
meeting demands to demand
management and
environmental sustainability.
Many water resources studies
I have worked on have been
in the context of the EU
Water Framework Directive
Alcantara Dam - Tagus River
Recent Water Resources Studies
• Ouse and Cuckmere Basins, South-East England.
• River Basin Management (Drin and Semani: Albania, Macedonia, Greece and Kosovo)
• Hydropower (Pelagus dam: Malaysia)
• Prut and Dneister tributaries (Moldova)
• Kagera Basin (Rwanda, Tanzania, Uganda, Burundi)
• Shire River (Malawi)
• Ili Basin (Kazakhstan)
• Severtsky-Donetz (Ukraine/Russia)
• Vardar/Axio (Macedonia/Greece

6. Political Sensitivity
Many of the river basins I have worked on are transboundary. For more than 10 years I was involved
in the Middle-East Peace Process for the European Commission and the Government of France.
Summary
When a river basin is shared between two or
more countries the need to achieve an
equitable balance of resource use is an
important and delicate issue. The photo, taken
when I was acting as an intermediary between
Lebanon and Israel, shows a pumping station
on a tributary of the River Jordan in Lebanon
viewed from the Golan Heights. The Israel
Prime Minister had been reported as saying
the construction of the pumping was casus
belli.
Wazzani Pumping Station - Lebanon
Shared river basins I have worked on
• River Mekong (China, Thailand, Laos, Cambodia and Vietnam)
• River Tagus (Tajo/Tejo, Spain/Portugal)
• River Hasbani (tributary of River Jordan: Lebanon/Israel)
• River Jordan (Syria, Jordan, Lebanon, Israel, Palestine)
• River Ili (China, Kazakhstan)
• River Niger (West Africa - 8 countries)
• River Okavango (Angola, Namibia, Botswana)
• Rivers Incomati and Maputo (Mozambique, Swaziland, South Africa)

7. Environment
Often I have worked in environmentally sensitive area such as Wetlands and Deltas. I have also
worked with the European Commission to try and improve the definition of Environmental Flows.
Summary
One of my skills is writing "one-off"
mathematical models and often this has been for
environmentally sensitive areas. I did this, for
example, in the Okavango delta. Recently I have
been modelling the effects of applying different
Environmental Flows.
Lake Balkash - Kazakhstan
Some environmentally sensitive areas I worked on include:
• Tonle Sap Lake (Cambodia)
• Okavango Delta (Botswana)
• Lake Balkash (Kazakhstan)
• Danube Delta (Romania)
• Pripyat Marshes (Belarus)
• Tagus - eFlows (Portugal/Spain)
• Waller's Haven (UK)

8. Academic Credentials
I did my first degree at Imperial College, University of London in Civil Engineering with specialisation
in water. I did my Masters at the University of Birmingham by Research into Hydrological Modelling.
Summary
I have published papers on my work in
journals such The Journal of Hydrology,
the Hydrological Sciences Bulletin, the
Proceedings of the American Society of
Engineers and the proceedings of the
Institution of Civil Engineers. The use, by
other researchers, of the hydrological
model I developed has also been
described in peer-reviewed journals.
