Introduction

Caesar Lisflood is a geomorphological / Landscape evolution model that combines the Lisflood-FP 2d hydrodynamic flow model (Bates et al, 2010) with the CAESAR geomorphic model to simulate erosion and deposition in river catchments and reaches over time scales from hours to 1000's of years.

If you want to contribute to this site, the wiki or the code development, please email me (T.Coulthard@hull.ac.uk) and I can add you as one of the site people (you will need a google/gmail email address/account).

The model is continually being developed - so if you download it please keep checking for updates and isses that may be reported with the version (or report issues yourself).

Key Features

• Landscape evolution model simulating erosion and deposition across river reaches or catchments, including slope processes operating over a wide range to spatial and time scales (1km² to 1000km², <1year to 1000+ years)
• A hydrodynamic 2D flow model (based on the Lisflood FP code) that conserves mass and partial momentum. (model can be run as flow model alone)
• Easy to use GUI
• Re-designed to operate on multiple core processors (parallel processing of core functions)
• Reduced parameterisation of flow model from previous CAESAR codes.

Guide to this site

These google code pages provide downloads of the .exe and the source code for CAESAR-lisflood and instructions and additional documentation can be found in the Wiki tab. These include a full description of all the parameters used in CAESAR, instruction videos and other information. I'm more than happy for people to help edit (in particular) the instructions - and these are in a wiki format, so you can log in and alter as you please.
