DIMS is the tool for building solutions turning data into information for valuable use in management and operation of utilities. The DIMS Concepts include configuration templates for real time monitoring and control of treatment plants. Concepts for online simulations of water distribution and collection systems apply the EPANET or the MOUSE engine. Models designed with MIKE URBAN Model Manager are supported.

DIMS consists of a number of components divided into three main areas:

• Hosts - the modules executing tasks distributed to different computers. Most tasks, including reporting, can be automated using the job scheduler, which executes macros.
• Clients - the interactive user interface used for configuration and presentation. The DIMS client supports user accounts and logins. This allows for configuration of individual and group rights to access information and features.
• Services - includes modules, which execute low level and basic functions.

Based on experience gained from projects, DHI has developed various concepts implemented with DIMS covering project areas like:

Wastewater treatment plants

• Cost reductions generated by savings on energy and chemicals
• More stable operation less affected by peak loads enhancing effluent quality
• Increased capacity of activated sludge tanks and clarifiers reducing investments

Water supply and distribution

• Information for unmonitored locations by virtual sensors
• Automatic alarm s help predict system failures
• Improved operation through state prediction
• Training tool for the system operators

Collection Systems

• Reduced overflows through real time operation
• Detailed information

Imagine if you had:

• A professional GIS package and be able to design a river basin model with your preferred GIS symbols, and combine it with any other GIS relevant information that makes your model easy to use and easy to understand by others.
• A simulation package for solving a multitude of water allocation problems, representing water availability and the usage in space and time for multi-sector basin planning, and describe rules with multiple types of priorities.
• A simulation package which could be easily developed for individual scheme analysis, e.g. integrated reservoir/hydropower systems or an irrigation command area, and undertake assessments from a project as well as basin perspective.
• An enhanced FAO-based irrigation demand and crop yield estimation tool for investigations of multiple irrigations schemes with multiple fields to study management strategies under water stress and drought situations, and their impact on crop production.
• A powerful environment for time series handling and analysis in GIS, where you could display monitoring stations, associate time series records, and easily perform time series analysis and manipulations of individual or groups of time series records.
• A GIS-based tool for estimating diffuse pollution loads from catchment areas, that combined with point sources provide input for river basin wide water quality impact assessment.
• A hydrological modelling system for rainfall-runoff estimation.
• An open programming interface that helps you to access and manipulate any input and output to or from your model, and assist you to change input parameters, look-up tables, otherwise specified in dialogs, and create the rules you need.

MIKE BASIN has all the above capabilities. A multi-purpose modeling and data management system beyond competition

If link directions flip along a network path or if flow patterns change due to pump operation, result layers of flow or velocity become difficult to read. Therefore MIKE Urban offers absolute values for those result types.

Load a result file, go to "Model Results > Result Manager", choose a result and click on "Additional". In the next dialog select "Absolute value of flow". "Calculate" writes the additional variable into the memory, and for the current MIKE Urban session absolute values of flow are now accessible like all other result types.

In "Model Results > Add Result Layer..." you'll find a new entry "Link: Absulute Flow" at the bottom of the dropdown menu. Add this layer to the project. Coloring is now much easier.

However flow arrows of absolute values do not necessarily point into the flow direction, so don't use them. Instead, add another Result Layer of type "Link: Flow". In the Layer Properties, Graduated Color, restrict the number of classes to one, and and make the one line invisible by using "No Color". In Layer Properties, Flow Arrows, choose "Use this color" and select e.g. black.

If you'd like to export your results to a shapefile with both absolute values and correct flow directions, follow these steps:

In MIKE Urban, add "Link: Flow" as a Result Layer, right click on the layer and save it as a shapefile.

Open the shapefile in ArcMap, start editing and open the attribute table.

With "Select by Attributes" select all records where "Results" < 0. Click on the "Shape" attribute, open the Field Calculator, load and execute calculation "polyline_Flip" from the excellent EasyCalculate collection. As a result all selected polylines now point into flow direction.

Click on the "Results" attribute, open the Field Calculator and compute Results = Abs([Results]). That's it.

If you like, import symbology from the flowarrows.lyr. It uses an arrow at the midpoint, which is not a standard feature in ArcGIS.

In 2003, 22 flood forecasting centres have been created in France to enhance the management of flood events. These require operational systems that can assist them in providing a better forecasting service to local authorities. The centre dealing with the River Seine (crossing Paris) has been equipped with DHI Software tools. Now, a second DHI Software system is being set up in France for the River Vilaine, the largest watercourse in Britanny (river catchment of 10000 km²).

This new flood forecasting system will use: MIKE FLOOD WATCH (real-time interface) and MIKE 11 (simulation tool). Several modules of MIKE 11 will be used: the RR module to estimate the input discharges, the HD module to model the river propagation and provide forecasted discharges and water levels at several locations, the SO module for the control structures operating on the river and the DA module to improve the real-time forecast accuracy.

This project will be carried out by DHI France with the assistance of DHI Denmark's experts in real time systems.

Strong focus on software courses worldwide in 2007

Almost 2.000 experienced, new and potential users chose to attend our MIKE software courses worldwide in 2007! The large number of participants can to a great extent be attributed to the significant efforts that have been put into developing training, capacity building and skills development as key components in the activities in recent years.

The trainees came from governmental agencies, regional and local water bodies, research institutions and universities, professional bodies and engineering companies, urban water utilities, coastal and harbour authorities throughout the world.

The participants' main reasons for attending the courses were:

• quick and efficient mastering of the software and accordingly project work; cost-effectiveness;
• upgrading of company teams' productivity, modelling skills and expertise;
• significant interest in coupling of models and products and mastering 1D & 2D integrated modelling;
• in-depth knowledge of products before final purchase.

For further information:

All existing, new and potential users are always welcome to contact us and to have a talk with our trainers. They are all highly experienced DHI modellers, who will discuss and advise you which training scheme will meet your specific needs and preferences most efficiently.

A good starting point will also be to consult our Global Course Calendar 2008:
