Title           Level 2/3 Undergraduate module in Fluvial Geomorphology
Abstract        This web based level 2/3 undergraduate module on fluvial geomorphology aims, via
                Units 1-4, to provide learners with a level of knowledge and understanding to allow
                them to pass a Level 3 University module in Fluvial Geomorphology. It also aims,
                via Units 5-6, to provide a suitable grounding for students wishing to undertake a
                dissertation study in the discipline. The module assumes some basic understanding
                of the principles of hydrology and geomorphology. The resource uses 146 images
                (terrestrial and air photographs, maps, graphs, diagrams, GIS generated digital
                terrain models), two VR Panorama movies and one time-lapse aerial
                photography movie to act as a stimulus to introduce topics. Each topic then refers
                the learner to Essential Reading and if appropriate to Further Reading to provide
                the detailed knowledge and understanding required at this level. Readings are
                graded by their level of 'friendliness' to the newcomer to the discipline.

Biography       An ex-field studies tutor and secondary school Geography teacher I joined Liverpool
                John Moores University as a Senior Lecturer in 1994. I have developed my
                research interests in fluvial geomorphology and latterly the applications of IT in
                teaching and learning. I have around 50 publications and in 2002 I was made
                Reader in Physical Geography and Outdoor Education. I have been programme
                leader for the BSc (Hons) in Outdoor & Environmental Education sine 1997.

Tutorial Type   Web based resource with stimulus images, image narrative, key points, directed
                reading and assessment tests.
Audience        Level 3 undergraduates (may also be suitable for level 2)
Prior           A level Geography, Environmental Science or related Level 1 undergraduate course
Time            Four units of 12-15 hours each = 60 hours total learning time.
Learning        After studying this module students will be able to:
                1. recall and understand the nature of the hydrological cycle and its importance in
                   the drainage basin system,

                2. understand the systems approach as applied to drainage basins and the
                   concept of the unit hydrograph,
                3. evaluate measurement and sampling techniques for estimating river discharge,
                   solute and sediment loads in streams and rivers,

                4. discuss the formation of fluvial landforms as observed in the landscape,

                5. synthesise the fluvial processes responsible for flooding, erosion, transport and
                   deposition of sediments and evaluate the impact of human activities.

Background     I have been a keen photographer for 25 years and have accumulated some 2 500
               35 mm slide transparencies plus in the last 2 years some 5000 digital images. Many
               of these have been taken during field visits to rivers around the world: UK, Iceland,
               Svalbard, Greenland, Australia, New Zealand, Nepal, China, New Mexico and the
               North American Rockies, Alaska and the European Alps. Three years ago myself
               and a colleague developed a level 3 undergraduate module in Glacial and Fluvial
               Processes and this resource has been developed as a means of helping me to
               assist students to access my research interests and lead them gently in to reading
               academic research in the area which they may not otherwise do.
Development    Prior to starting to develop this resource I had written an extensive personal web
and Creation   site as far back as 1997. This I used for mounting learning resources for students
               so I’ve had an interest in doingthis for the pst 5 years. I had intended to use
               Macromedia Dreanweaver to develop the resource but after the author’s meeting at
               Bristol another author recommended Mindmanager Standard Edition 2002 v4.6.171.
               After downloading a trial version I was impressed with the organisation powers of
               this software as well as the presentation being better than I could write in
               Dreamweaver so I purchased this using project funding. I also purchased VR
               Panoworx for creating Quicktime VR Pamorama movies. I borrowed a suitable
               tripod for capturing the images from a colleague. Photographs were taken: slides
               using a Pentax ME Super with 35-210 Tamron zoom lens; digital images were taken
               using an Olympus Camedia C-700 digital camera.

               In addition I made extensive use of: Adobe Photoshop 5.0 for scanning and image
               manipulation linked to a Prime Film 1800 slide scanner and a Umax 1200U flatbed
               scanner. PowerPoint was used for drawing diagrams, Excel for creating graphs and
               maintaining the image log.
Image          All images, with the exception of historical air photographs used to make a time-
selection      lapse movie, were taken by me and I own the copyright. Copyright permission was
               obtained from Dr Nick Mount to use his DTM image and Fig. 4.15 from his PhD
               thesis. Al images are saved in TWO folder: Fluvial Images contains the largest and
               best versions of the images in .GIF format. Fluvial folder contains the same .GIF
               images reduced to 400 pixels wide (or high if portrait format) deemed a suitable
               compromise for web use.
Problems and   The greatest problems were encountered with the VR Panorama movies. First the
Obstacle       software had to be purchased and the tripod borrowed, with some instruction on its
               use. No instruction was sought for using the software but after some trial and error
               the first panorama movies appeared. I still have a lot to learn here, particularly
               regarding the setting up of hot spots which I intend to do in future. Also, for this work
               my digital camera does not have a high enough resolution and my PC would
               probably need more RAM (128 MB RAM, 550 MHz processor at present) and speed
               to cope with the higher quality images.

               I have also learned a bit about how to export images from Adobe photoshop to .GIF
               formats, but I still need much more training with this software to get the most from it.

               Some support from Howard Richardson was required (3 occasions) re: exporting
               images from photoshop; VR panorama movies and setting up HTML code to get
               control bar on movies; and with relative hyperlinks within the resource.
How to         This tutorial took approx. 50-60 hours to create plus one field day taking photos for
duplicate      VR panorama movies plus another day learning the technique.
Recommendat    Very enjoyable and satisfying. Not sure if I can recommend it to everyone!
