Visual CAESAR

Latest Release (full details of changes are on the discussion board. NOTE CAESAR is distributed under a GNU public license - details at the end of this page)

Notes on the most recent version available here or on the discussion board. The zip file of the stand alone version now uses a windows installer - so download the zip file, uncompress it in a temporary folder and run the set up program.

If you just want the .exe, best to download and unzip the source code, the .exe is found in the folder bin>release> if you use this version, the graphs will not work.

If you have any problems with this please email me T.Coulthard@hull.ac.uk

Sample files
For both these examples, you will need to download the latest exe code (above) or compile your own from the source. Unzip from the file downloaded (below) into a new folder. Double click on the CAESAR .exe file, open the config file from the downloaded files below, click load data and start. Instructions can be downloaded from further down this page.

River Swale example (CAESAR in catchment mode)
Meandering example (simple sinusoidal channel)

CAESAR has been ported to visual C#, compiled as part of the Microsoft .net visual studio. It has all of the functionality of the regular CAESAR - and more - as well as now having an easy to use windows type front end. These pages contain all the files you need to run and use Visual CAESAR as well as some instructions and sample data.

Why Visual C#? Well, for years I have been coding CAESAR in C, and running it on unix platforms. But it has a rather unfriendly front end (none!) and the outputs have to be viewed with a GIS package. I tried using various X windows libraries and solutions, but had little success, so had a go with Vis C#. This allowed me to create windows, graphics menu's etc.. and also port over the C code very easily (really only had to change some variable definitions and the brackets around arrays). The downside is that it runs at 50-70% of the speed - but you get to see instant results, and this is important when setting up the model, to see it is working properly. Furthermore, I now have two other people working on CAESAR (Dr Gez Foster and Ian Dennis) and they have found it FAR easier to both use the windows version and program in C#.

CAESAR is distributed under a GNU public license (details at the end) and is free for you to use and modify to your hearts content, though if you do I'd be very interested in what you do, and what you find out!

Requirements
In order to run Vis CAESAR, you will require a PC (at least 500mhz - and 128+ memory) running Windows 98se, NT4 (plus service pack 6a onwards), WindowsME, 2000 or XP. Latest versions of XP have the required files downloaded (so you can try without first if you like) or you will either need a copy of Microsoft .net visual studio loaded, or download the following files, that Vis CAESAR uses. If you'd rather trust the Microsoft website than me, then this can either be done by clicking here, and following the link on the MS pages to Microsoft .NET Framework Version 1.1 Redistributable .  Beware, they are quite large (25mb) but are unfortunately needed by Vis CAESAR.

If you wish to compile the source code, you can either buy a copy of MS visual studio .net (expensive) or you can actually download the compilers from the Microsoft web site here, following the link to Microsoft .NET Framework 1.1 Software Development Kit. You do not get all the fancy features and integrated development environment that comes with visual studio, but it works. This file is even larger (105mb).

There are other Compilers that will compile the C# code (there is one from Borland I believe) and the 'mono' project to create one for unix/linux workstations.

New 7/11/2006. I have found much success using the new freely available Visual C# express compiler - can be found here: http://msdn.microsoft.com/vstudio/express/visualcsharp/

Instructions
Simple Instructions/guidlines for the above examples are here.

Older fairly detailed instructions and examples are provided in the following word document. These instructions are a bit rough and ready, but if you have any suggestions or wish to edit them, please do so and email me a copy!

Raster edit
This is a really neat program written by Marco Van de Wiel, that allows you to load up the DEM used by CAESAR (in the ascii format) and edit cells. This is really useful for editing the bedrock file, and/or removing any channel obstructions in the DEM. Download here. The newer version posted here, now contains interpolation and smoothing functions.

Acknowledgements:
CAESAR and TRACER development is now a team effort, with the involvement of Ian Dennis, Dr Gez Foster and many of the ideas and improvements have been the products of discussions with Dr Marco Van de Wiel - all from the UWA Aberystwyth. Many thanks to all of them.
