MIKE URBAN modellforenklings-veiviser automatiserer nettverkssegregering (dataskrubbing, -klipping og -sammenslåing) til både avløps- og vannforsyningssystemene. Forenklingene reduserer nettverkets kompleksitet, som igjen forbedrer effektiviteten til de hydrauliske utregningene uten å kompromittere integriteten og nøyaktigheten til modellen. Forenklede nettverk blir brukt i forskjellige sammenhenger som on-line modellapplikasjoner, langtidssimuleringer og til utvikling av strategiske modeller og lignende.

Skrubbing fjerner frakoblede elementer i nettverket. For eksempel noder og linker som ikke er sammenkoblet, enderør basert på brukerspesifiserte kriterier som rørlengde kortere enn spesifisert lengde og rør med mindre diameter enn brukerdefinert diameter

Klipping fjerner deler av nettverk som er utenfor interesseområde som for eksempel store nettverksforgreininger. Alle tilkoblete elementer som nedslagsfelt og vannbehov blir koblet automatisk til de gjenværende nettverkselementene basert på brukerspesifikasjoner

Sammenslåing fjerner interne rørnoder ved å smelte de sammen til et rør med like hydrauliske egenskaper som de opprinnelige rørene. Alle tilknyttede elementer som nedslagsfelt og vannbehov blir automatisk tilknyttet det gjenværende nettverket

Den andre servicepakken for MIKE Zero er klar for nedlasting senere denne måneden.

Et antall læringsprogram på video har blitt laget for MIKE URBAN 2007 for å tilby en bedre forståelse av programvaren og steg for steg brukerinstruksjoner.

Disse programmene inkluderer en rask innføring i modellering av drikkevanns- og avløpsnettverk, hvordan forenkle nettverk, hvordan bruke “scenario manager”, hvordan kjøre brannvannssimuleringer med mer.

MIKE Urban tilbyr brukerdefinerte snarveier for mange kommandoer. Bruk eller med skriveknappene og en hvilken som helst kombinasjon av , og med funksjonsknappene.

Følgende figur gir et eksempel på hvordan de numeriske tastene kan brukes til å utføre kommandoer med et enkelt tastetrykk.

Rediger modeller mye raskere enn før: Zoom inn <+>, velg nedslagsfelt <1>, koble til node <4>, fjern selektering <0>, pan around <*>, velg nedslagsfelt <1>, koble dem til en node, osv. Bruk en hånd til talltastene og den andre til musa. Du må ikke bruke venstre hånd på musa, men klikk her for å se fordelene.

Kobling av noder er bare et eksempel. Snarveiene kan brukes til enhver redigeringsoppgave hvor du ellers ville klikket mye på de forskjellige verktøyene.

For å tilordne snarveier, gå til meny Tools > Customize > Shortcuts. Velg en kommando fra listen og trykk ”Create Shortcut”. I neste dialog ”Assign Shortcut” velger du den ønskede tasten (eller kombinasjon av taster). Bekreft med OK. ”Remove” fjerner en enkelt snarvei. ”Reset All” oppretter de originale innstillingene.

Eksempelet ovenfor bruker følgende oppsett:

View: Zoom Data: Fixed Zoom In: + (NUMERISKE TASTER)
View: Zoom Data: Fixed Zoom Out: - (NUMERISKE TASTER)
View: Zoom Data: Full Extent: / (NUMERISKE TASTER)
View: Zoom Data: Pan: * (NUMERISKE TASTER)

Tools: Selection: Clear Selected Features: 0 (NUMERISKE TASTER)
Tools: Selection: Select Features: 1 (NUMERISKE TASTER)
Tools: Selection: Select by Polygon: 2 (NUMERISKE TASTER)
Tools: Selection: Zoom to Selected Features: 3 (NUMERISKE TASTER)

SWMM5: Catchment Tools: Connetct To Node: 4 (NUMERISKE TASTER) ...fungerer med både MOUSE og SWMM5!

Når man installerer en ny versjon av MIKE Urban blir snarveiene slettet, så skriv ned formateringene dine og overfør dem på nytt.

Hyder Consulting (UK) Ltd. are supporting Birmingham City Council with one of DEFRA’s (Department for Environment, Food and Rural Affairs) innovative fifteen new projects investigating how to reduce the impacts of urban drainage flooding in towns and cities across England. MIKE FLOOD has been selected by this pilot as the modelling tool being trialled to assist understanding of the local urban drainage problems.

For further details please see here

DHI Spain has recently finalised an inundation study for the Spanish company, Llorens Fornes S.L, in the province of Valencia. The objective of the study was to investigate if an area, in the village of Masalavés, would inundate during three different storms (T=25, T=100 y and T=500-year storms). The results and conclusions will be used as part of the zone re-classification process (rural to urban).

The study area with indication of the city of Masalavés and the river Júcar.

As shown in the figure, the inundation is caused by a combination of two factors: local rain, and overflow from the river Júcar.

The model was configured with the river Júcar incorporated as an open boundary, and the local rain introduced via the "new" facility in M21 version 2007 called "rain on land". The facility enables a simple hydrological model consisting of basically 2 parameters; precipitation and evaporation, which can be defined as a constant, time series, or map (2D). Factors such as infiltration, run off coefficients etc need to be incorporated into one of these two parameters.

Although it is simple, it is very useful for modelling flooding of areas without clearly defined flow-paths, as was the case in this study.

The results show that the local rain plays a vital role in mapping the flood risk areas. Furthermore, the study showed that it would be challenging to model each of the streams with an 1D model using the traditional cross sections and a pre-defined river network.

The conclusion was that the area in question was not located within a flood risk zone, considering the three return periods.

Every year hundreds of members of DHI software community meet around the globe at one of our regional or national Conferences, User Group Meetings, round-tables or workshops.

The events offer an excellent opportunity to exchange experiences and ideas with fellow users and colleagues in an informal spirit - and to discuss the latest developments of our software.

A number of software training courses are normally offered in connection with our Conferences and User Group Meetings.

Groundwater modelling -  Moving beyond MODFLOW
Shrewsbury, UK, July 3rd 2007

MODFLOW is a valuable tool in our modelling toolbox and will continue to be so for many years to come.

However, our needs have evolved considerably since the mid-1990s, when the first MODFLOW user interfaces became widely available.

To name just a few, we are now challenged by 

• Coupled groundwater-surface water interactions
• Distributed, dynamic recharge
• Fully integrated hydrologic water balances
• Detailed, irregular geometry
• Heat and density dependent flow
• Complex reactive solute transport processes
• Fracture flow
• etc. etc.

Please join us for a one-hour and informal seminar, where Douglas Graham will explore how FEFLOW and MIKE SHE can complement your MODFLOW modelling tools, and expand your modelling horizons.

International Conference ModelCARE 2007

Calibration and Reliability in Groundwater Modelling, Credibility of Modelling, Copenhagen September 9-13, 2007

Though the conference will cover the entire field of groundwater modelling the overall theme of the 2007 ModelCARE conference is Credibility of Modelling.

The principle topics addressed in the conference include:

• Credibility of modelling perceived by water managers and stakeholders in water resources management
• Geological modelling and conceptual model uncertainty
• Integrated hydrological modelling (coupled descriptions of saturated, unsaturated, surface water)
• Modelling of reactive and density affected transport
• Value of data at different spatial and temporal scales for model uncertainty reduction
• Use of new data types from geophysical and remote sensing techniques
• Developments in modelling and uncertainty assessment
• Parameter estimation and model calibration
• Groundwater modelling in relation to the Water Framework Directive and the Groundwater Directive

DHI staff will be presenting papers and posters as well as one of the key note addresses. A booth will be available where you can learn more about DHI's groundwater related products, MIKE SHE and FEFLOW. A FEFLOW course will be held prior to the conference.

Conference information is available here.
