 The core of ANUGA is a Python implementation of a finite-volume method
-for solving the Shallow Water Wave equation.  This method allows the
-study area to be represented by an unstructured mesh with variable
-resolution to suit the particular problem.  Another important
-capability of ANUGA is that it can robustly model the process of wetting and
-drying as water enters and leaves an area. This means that it is
-suitable for simulating water flow onto a beach or dry land and around
-structures such as buildings.
+for solving the conservative form of the Shallow Water Wave equation.
+This method allows the study area to be represented by an unstructured
+mesh with variable resolution to suit the particular problem.  The
+conserved quantities are water level (stage) and horizontal momentum.
+An important capability of ANUGA is that it can robustly model the
+process of wetting and drying as water enters and leaves an area. This
+means that it is suitable for simulating water flow onto a beach or
+dry land and around structures such as buildings.
 
+To set up a particular scenario the user generates a mesh with regions
+and boundary segments identified by symbolic tags used to bind values
+to arbitrary functions supplied during the simulation.  In addition,
+all quantities may be assigned or updated by supplying either constant
+values, arbitrary functions or general expressions combining existing
+quantities.  Arbitrary forcing terms such such as wind stress or
+atmospheric pressure gradients may also be supplied.  
+
+Computationally intensive components are written for efficiency in the C
+language working directly with the Numerical Python structures while 
+the interface aims at flexibility using Python's object model, weak typing and
+constructs such as generators.
+
+ANUGA will be released under an OSS license. This strategy will enable
+free access to the software and allow the risk research community to
+use, validate and contribute to the development.
