Flood Defence Manager
Title Slides Your audience needs to know who you
are and what you are going to talk about. Give
your presentation an opening slide showing the
title of your presentation, your name and
position or job title. Keep it simple. Your
audience is far more likely to be distracted at
the start of the presentation, when they are
still settling down. Job titles should be kept to
a single phrase - Managing Director or Events
Manager - and qualifications used only if they
are strictly relevant to your audience or
presentation. Your closing slide should mirror
the opening one, showing the title of the
presentation and any contact details, if those
are relevant. You can duplicate blank title
slides, either by holding down Ctrl and
click-dragging into the desired position in Slide
Sorter mode (View - Slide Sorter), or by using
Insert - New Slide - Title Slide.

based on existing guidance. Precautionary
allowances shown in italics have been scaled in
relation to global mean temperature changes and
rounded to the nearest 5

Revised precautionary allowances for net sea
level rise in PPS25
The allowances incorporate thermal expansion of
the oceans, melt from land glaciers and vertical
adjustments of the land. Contributions from tidal
surge and waves are not included.
