The Food and Agriculture Organization of the United Nations (FAO/UN)
is coordinating a two-day training exercise in flood modelling on Tuesday 30th
– Wednesday 31st October, 2019.
The workshop is a component of the four-year project “Improving Forest
and Protected Area Management in Trinidad and Tobago” which the FAO is
implementing on behalf of the Government of Trinidad and Tobago.
This workshop
activity will enable participants – including staff of the Drainage Division,
Ministry of Works and Transport and the Division of Infrastructure, Quarries
and Environment, THA – to become familiar with aspects of the hydrology of
catchments and their influence on receiving floodplains. The focus of the workshop will be on the
development of design storms and the application of techniques for generating streamflow
hydrographs emanating from catchments.
This workshop sets the stage for a follow-up session in early
November in which participants can understand how the streamflow hydrographs flowing
onto a floodplain may cause flooding. It
will explore the capabilities and limitations of a popular two-dimensional
hydrodynamic model and how it can be used for performing hydraulic analyses for
evaluating the suitability of flood control measures. The model’s capability for producing flood
hazard maps will also be covered.
The workshop is
linked to a current feasibility study being undertaken in the project to
identify possible options for improving freshwater input into the mangrove
swamp forest of the Caroni Swamp. If a
feasible option is identified, improved freshwater flow to the Swamp may also
provide an associated solution to reduce or mitigate flood challenges in
surrounding areas.
