MODELLING OF STORMWATER DRAINAGE NETWORKS

AND SEWER COLLECTION SYSTEMS

using MIKE URBAN

Development and rehabilitation of urban collection systems can pose major challenges to planners and engineers. The systems must be cost-effective, yet also sufficiently resilient to handle the effects of demographic processes as well as the consequences of climate change. Moreover, neither of those processes are easily predictable. To meet these challenges, access to the right tools is essential. MIKE URBAN helps you make sound decisions in a challenging world. MIKE URBAN makes you the expert and enables you to create future concepts for urban stormwater drainage networks and sewer collection systems - concepts that are cost-effective as well as resilient to change.

SUSTAINABLE DESIGN STRATEGIES FOR SEWER SYSTEMS

Using MIKE URBAN, evaluation and optimisation of rehabilitation concepts can

be performed with respect to:

Hydraulic performance

Cost-benefit analyses

Mitigation of flooding caused by extreme events

Modelling of all water in the city

Estimation of potential risks for current systems as well as future scenarios

Carrying out integrated city wide planning of sewer system expansion and

rehabilitation - also taking urban flood protection into account.

Constant challenges with respect to extension and rehabilitation of urban drainage systems.

SUSTAINABLE MODELLING

One of the typical MIKE URBAN applications is hydraulic

modelling in urban environments. It is particularly modelling

of rainfall-runoff, its discharge through open or closed pipes

as well as on the surface.

MIKE URBAN IS USED FOR

Master planning of collection systems

Wet weather management planning to reduce overflows

Hydraulic rehabilitation planning

Capacity management and operational maintenance

Rainfall dependent inflow and infiltration

Modelling of sediment transport and water quality

parameters

Emergency response planning for urban flooding

With the help of hydraulic models you get a much better

understanding of rainfall-runoff and discharge processes

in urban areas. Furthermore, detailed cost-benefit analyses

enable consultants and engineers to create scenarios to

optimise existing infrastructure, resulting in rational and

reproducible city planning workflows.

MIKE URBAN models are based on the best available

mathematical solutions to the physical characteristics of

the system. Thus, hydraulic processes are handled very

accurately. That’s one of the reasons why MIKE URBAN

is the right choice, when you have to design or optimise

cost-intensive infrastructure projects.

ACCURATE SIMULATIONS

The high degree of accuracy is achieved by using DHI’s

computational engines, MOUSE and MIKE 1D - with

unrivalled numerical stability and accuracy. Furthermore, it

is achieved by simulating catchments based on their actual

spatial geometry and the corresponding hydrological

parameters.

MIKE URBAN also models transportation of dissolved

substances and sediments based on actual physical

principles.

Additionally, simulations of networks with existing or

planned components, such as pumps, weirs or valves up to

complex PID control strategies can be launched using MIKE

URBAN - including under real-time conditions. The MIKE

URBAN engines can be integrated into operational

monitoring and control systems.

DATA MANAGEMENT THAT WORKS

Data management in MIKE URBAN includes:

Fully customisable import and export with many templates

Create/import/edit time series of rain events

Create cross-sections based on digital elevation models

PRESENT RESULTS IN AN UNDERSTANDABLE

MANNER

Flexible and easy to understand presentation of results and

derived action plans towards decision makers and

stakeholders is as important as the actual simulation itself.

MIKE URBAN provides the following presentation tools:

Rich symbolisation and labelling options due to seamless

integration with ArcGIS

Static or animated results presentations such as maps,

longitudinal profiles and time series

Export of results to various GIS data formats and video

files

Freeware result viewer: MIKE View
