MIKE 21 Quick Start Guide (Flexible Mesh Series)
Over the past few months, we have prepared several short instructional documents in the use of the MIKE Zero Mesh Generator, MIKE 21 FMHD and MIKE 21 SW from a UK perspective. These instructions have been collated into the informal working document 'MIKE 21 Quick Start Guide' below: -
We have been working hard to enhance our User Manuals and Scientific Documentation. For example, the above informal guide can be augmented by our new Mesh Generator Step-by-step Guide (2012): -
How to Create a Directional Wave Spectrum for Input to MIKE 21 SW from Buoy Data
In order to make best use of the new Wave Spectra Converter tool available in Release 2012, some pre-processing of wave buoy data is generally required. In response to a number of recent enquiries, we have prepared the following informal guidance: -
Oil Spill Modelling
It is important to note that the methodologies of the old and new oil spill models in MIKE 21/3 are very different, and a direct comparison is difficult. However, in order to provide some basic guidance, we have developed the following comparison document and associated example models (provided here for information and discussion only): -

Australian Rainfall and Runoff 2012 (AR&R) Guidelines Launched: Two Dimensional Modelling in Urban and Rural floodplains
Engineers Australia has published new guidelines on Two Dimensional Modelling in Urban and Rural Floodplains. The guidelines have been prepared for the National Committee on Water Engineering as one of the Australian Rainfall and Runoff Revision Projects.
The Guidelines review current practice in 2D modelling, including areas where current practice is not supported by theoretical and empirical research, and provide guidance on appropriate development and usage of 2D hydrodynamic models for floodplain applications.
While tailored to Australian flood risk legislation, UK users of MIKE FLOOD may find the report of interest (particularly, for instance, the sections on building representation and the use of eddy viscosity in 2D inundation models).
The report builds in part upon the research undertaken by Grantley Smith (University of Newcastle, NSW) on 2D Flood Modelling in Urban Areas (specifically in Merewether; a suburb of Newcastle, New South Wales) which he presented at the 2012 UK User Group Meeting.

Integrated Surface and Groundwater Model Review and Technical Guide
The Ontario Ministry of Natural Resources has published a guideline report evaluating the applicability of integrated surface and groundwater hydrologic models including MIKE SHE, GSFLOW, and HYDROGEOSPHERE. While tailored to Ontario watersheds, UK users of MIKE SHE may find the report of interest.
"While integrated models are able to provide a more complete representation of hydrologic processes, they have not yet seen widespread application within Ontario. To address this knowledge gap, the Ontario Ministry of Natural Resources initiated a study to determine the applicability of integrated hydrologic models to Ontario watersheds. The report includes: a qualitative comparison of several integrated model codes; the application of multiple integrated model codes to two case-study watersheds; and guidance to water resource practitioners on how to develop and calibrate an integrated model." from WaterBudget.ca (2011)

Climate Change – Adapting to the Future
Climate change will mainly hit us first through water. In order for societies to prepare for this, the global challenge is to reduce the vulnerability of natural and human systems. There is a rapidly increasing need to create adaptation actions in order to manage the effects of extreme water rainfalls, heavy storms, droughts, etc.
Together with clients and organisations worldwide DHI has for decades been developing solutions for climate change adaptation. We have now compiled our comprehensive knowledge and experiences in three Climate Change Adaptation Guidelines. They give a state-of-the-art overview and also describe in detail the methodologies to be used to achieve sustainable climate change adaptation within the areas of Water Resources, Urban and Marine.
The guideline for the urban area describes for example how flooding from the sea and from drainage systems can be countered in cities. Tools and methodologies are described and evaluated and so is the planning of flood emergency preparedness.
The marine area guideline describes the climate change impacts on water levels, waves and temperature. You get methodologies for preparing marine infrastructure projects and for developing sustainable solutions for harbours and coastal cities.
It is vital for the future survival of many societies e.g. in Africa to achieve sustainable climate change adaptation within water resources. But how can one evaluate the impact from various CO2 emission scenarios and transform them into impact on precipitation? This is just one of the difficult procedures described in this guideline.
Climate change guidelines for your use
The three guidelines are all available for public download. Please feel free to share them with your colleagues and friends. The guidelines can be downloaded here: -
Through this initiative, it is our wish to increase DHI’s contribution to a sustainable adaptation to climate change. For further information please contact Jacob Høst-Madsen, Consultancy Director, DHI.
