Integrated Water Resources Plan for Sistan inland delta in Iran
WL | Delft Hydraulics has completed an Integrated Water Resources
Management (IWRM) study for the Sistan delta in Iran. The Sistan delta
is the downstream part of the Hirmand (Helmand) river basin which for
a major part (95%) is located in Afghanistan. To determine the
boundary conditions for the IWRM analysis of the Sistan delta it was
needed to develop a flow forecasting system to make long-term and
short term predictions of the flow in the Hirmand that will enter
Iran. The flow forecasting system makes use of satellite data for snow
cover in Afghanistan and of medium-range weather forecasts for
rainfall and temperature. This was combined with a rainfall-runoff and
a water management model for the basin, all put under a Delft-FEWS
umbrella. The IWRM analysis for the Sistan area itself is based on a
RIBASIM application.
The main IWRM challenge of the area proves to find a balance between
the development of irrigated agriculture (in Iran and Afghanistan) on
the one hand and the protection of the three lakes (hamouns) in the
Sistan area on the other hand. The hamouns have important ecological
values (large parts are assigned as Ramsar sites) and they provide a
livelihood for many rural people around the lake. The client of the
project (the Ministry of Energy in Iran) is in touch with the
responsible authorities in Afghanistan to discuss the results and to
continue the IWRM analysis for the full Hirmand basin.

Umbrella Water Sector Plan in Lesotho
The country of Lesotho in South Africa forms the main source of water
for the Orange river, one of the largest rivers in the region.
Nevertheless the country faces severe water-related problems in terms
of water supply and a well-founded water resources management strategy
is required. WL | Delft Hydraulics forms part of a consortium with
SWECO Groner from Norway that was awarded the Phase 1 of the Lesotho
Water Sector Improvement Project, that will be implemented between
2005 and 2007. Our main task is the development of the Umbrella Water
Sector Plan using the technical capabilities that were applied
successfully in earlier projects in countries as diverse as Indonesia,
Trinidad & Tobago, Mali and Greece.

Delft Hydraulics involved in Joint Industry Project
Recently, WL | Delft Hydraulics has started work on a project called
JIP HAWAI. JIP is short for Joint Industry Project, which means that
the project is directly financed by participants from the (oil and
gas) industry and HAWAI stands for sHAllow Water Initiative. The
project involves a co-operation with MARIN (Netherlands), Delft
University of Technology (Netherlands), Bureau Veritas (France) and
Single Buoy Moorings (Monaco). In this cooperation the combined
expertise of offshore hydrodynamics and coastal engineering will be
used to study shallow-water wave conditions in order to provide
reliable wave information for an optimal design for offshore LNG
facilities.

harmful algal bloom early warning system
ISCHA: integrated spatial and spectal characterisation of harmful
algal blooms in Dutch coastal waters
Harmful algal blooms of Phaeocystis occasionally cause mass mussel
mortality in the aquaculture area Oosterschelde, the Netherlands. To
enable early warnings about future harmful algal blooms to mussel
farmers and other end users, an information system is developed based
on the combination of remote sensing data, field data and model data
from WL harmful algal growth model GEM for the Dutch Voordelta area.
The information system is being developed as a collaboration between
WL | Delft Hydraulics, IVM (Free University, Amsterdam ) and the
National Institute for Coastal and Marine Management (NICMM). The
system is planned to be operational in spring 2006, delivering algal
bloom information bulletins on the present and expected development of
algal blooms in the area to mussel farmers twice a week during the
riskful spring period.

CEDA-meeting at WL | Delft Hydraulics, 24 January
On January 24th WL | Delft Hydraulics hosts a CEDA-meeting. Theme of
this meeting is 'Dredging conflict between Singapore and Malaysia'.
Presentations will be given by Prof. ir K. dAngremond (emeritus
professor in Coastal Engineering) and Dr ir A. Minns (Manager - Mud,
soil dynamics and ecosystems at WL | Delft Hydraulics.
The Republic of Singapore suffers from a lack of space that
significantly hinders its ambitions in social, economic and cultural
areas. For this reason, an ambitious Master Plan for land reclamation
has been developed. In 2002, two major works were started: Tuas View
Extension and Pulau Tekong. However, the neighbouring country of
Malaysia felt that these major works were damaging to Malaysian
interests. Malaysia subsequently filed a lawsuit against the Singapore
land reclamations at the International Tribunal for the Law of the Sea
(ITLOS).
After extensive research in 2005 a solution was found that was
acceptable for both countries. A Committee of Scientific Experts
played a major role in the resolution of this dispute. Professor
dAngremond was a member of this Committee. He will give a presentation
about the technical and legal aspects of this case.
WL | Delft Hydraulics was asked by Singapore to perform extensive
model studies of the effects of the land reclamation project at Pulau
Tekong in order to provide the Committee of Scientific Experts and the
ITLOS with sufficient relevant information with respect to the
consequences of the land reclamation project. Results of these studies
were used to perform impact assessments on hydrodynamics, navigation,
morphology, hydrology, water quality and aquaculture. Tony Minns was
project leader of this study. He will give a presentation about the
approach and results of this project.
