+----
+=== Description ===
+simplify and improve the lateral diffusion and dissipation in NEMO/OPA 
+
+Simplification: [[BR]]change the way the eddy diffusivity and viscosity are specified and controlled by the user.
+
+Improvements: [[BR]] (1) introduce Beckers et al. (2000) compact stencil in the cross-isoneutral direction in triads formalism ; [[BR]] (2) introduce in both iso-neutral operator the Method of Stabilizing Correction (Lemarié et al. (2012) ; [[BR]] (3) implement bilaplacian iso-neutral operator (Lemarié et al. (2012)
+
+----
+=== Testing ===
+Testing could consider (where appropriate) other configurations in addition to NVTK].
+
+|| NVTK Tested || !'''YES/NO!''' ||
+|| Other model configurations || !'''YES/NO!''' ||
+|| Processor configurations tested || [ Enter processor configs tested here ] ||
+|| If adding new functionality please confirm that the [[BR]]New code doesn't change results when it is switched off [[BR]]and !''works!'' when switched on || !'''YES/NO/NA!''' ||
+
+(Answering UNSURE is likely to generate further questions from reviewers.)
+
+'Please add further summary details here'
+
+ * Processor configurations tested
+ * etc----
+
+=== Bit Comparability ===
+|| Does this change preserve answers in your tested standard configurations (to the last bit) ? || !'''YES/NO !''' ||
+|| Does this change bit compare across various processor configurations. (1xM, Nx1 and MxN are recommended) || !'''YES/NO!''' ||
+|| Is this change expected to preserve answers in all possible model configurations? || !'''YES/NO!''' ||
+|| Is this change expected to preserve all diagnostics? [[BR]]!,,!''Preserving answers in model runs does not necessarily imply preserved diagnostics. !'' || !'''YES/NO!''' ||
+
+If you answered !'''NO!''' to any of the above, please provide further details:
+
+ * Which routine(s) are causing the difference?
+ * Why the changes are not protected by a logical switch or new section-version
+ * What is needed to achieve regression with the previous model release (e.g. a regression branch, hand-edits etc). If this is not possible, explain why not.
+ * What do you expect to see occur in the test harness jobs?
+ * Which diagnostics have you altered and why have they changed?Please add details here........
+
+----
+=== System Changes ===
+|| Does your change alter namelists? || !'''YES/NO !''' ||
+|| Does your change require a change in compiler options? || !'''YES/NO !''' ||
+
+If any of these apply, please document the changes required here.......

+=== Resources ===
+!''Please !''summarize!'' any changes in runtime or memory use caused by this change......!''
+
+----
+=== IPR issues ===
+|| Has the code been wholly (100%) produced by NEMO developers staff working exclusively on NEMO? || !'''YES/ NO !''' ||
+
+If No:
+
+ * Identify the collaboration agreement details
+ * Ensure the code routine header is in accordance with the agreement, (Copyright/Redistribution etc).Add further details here if required..........
