1. SUMMARY

Aalto University is located at Otaniemi in the city of Espoo in the Helsinki metropolitan

area. During the team building phase we will be located at the Tvärminne Zoological station

which is a marine research station located at the entrance to the Gulf of Finland in the

Baltic Sea (Tvärminne: http://luoto.tvarminne.helsinki.fi/english/index.htm). It is situated

in a nature reserve, where only research and teaching activities are allowed.

A total of 24 students from four different European

countries, France, Italy, the Netherlands and Finland,

will have the chance to participate in this international

project.

Our project theme is stormwater management in the Kumpulanpuro (Kumpula creek)

catchment area in Helsinki. Kumpulanpuro is a heavily modified and partly restored stream

on an important location in the middle of Helsinki. The catchment collects rainwater and

runoff from a large area with varying land use including housing, Pasila railway yard, old

landfill, old quarpits and two valuble natural areas.

Aalto University is hosting the course in cooperation with the research groups: Clean

Technologies (Forest Products Technology) at Aalto University School of Chemical

Technology and Water Engineering (Civil and Environmental Engineering) at Aalto

University School of Engineering.

Partner schools

NHL University of Applied Sciences, School of The Built Environment (NHL Hogeschool,

Leeuwarden) The Netherlands; University of L'Aquila, Department of Architecture and

Urban Planning (Università degli studi del l'Aquila), Italy; University Institute of

Technology, Department of Civil Engineering, Béthune (IUT de Béthune), France and Aalto

University (Aalto yliopisto), Espoo, Finland.

Course Dates

The course runs from Friday 1st of April to Saturday 9th of April 2016. Both Friday 1st and

Saturday 2nd of April will be spent on an orientation weekend in Tvärminne, Hanko (more

info in 3. PRACTICALITIES). The remaining nights 3rd to 8th of April will be accommodated

PRACTICALITIES).

Aims of the project

Sustainable solutions for Kumpulanpuro catchment that address some of the following

issues or themes:

1. Flooding & other hydrological responses

2. Environmental load, water quality

3. Mixed (wastewater and stormwater) sewers

4. Landscape and social environment

5. Ecosystem services

6. Environmental management

7. Adaptation to climate change





2. PRELIMINARY ASSIGNMENTS

These assignments are to be completed before students travel to Finland.

2.1. ASSIGNMENT 1 PART A (INDIVIDUAL ASSIGNMENT)

Part A is an individual assignment that should result in one typed A4 pages per participant,

written in English. Students should upload their self-introductions to MyCourses portal

(students will be registered after selection) by 29/2/2016. They will be visible to other

students. MyCourses: https://mycourses.aalto.fi/course/view.php?id=11509

For the filename of your document please use the following format:

partA_country_firstname_familyname for example: partA_UK_John Smith

Assignment

The main aim of the international projects is the co-operation with students from other

nationalities and other disciplines. In part A of the preliminary assignment, you describe

how you think this co-operation will work out. You should incorporate the following 3

aspects.

1. Write a personal introduction, in which you tell about yourself.

• Say something about yourself, your personal interests, where you live, you describe

your area of study and your skills. Describe with what kind of person your fellow students

will have to co-operate.

• Describe in what way you can identify with the problem as described in the project

description, considering your own area of study.

2. Describe what you expect of the co-operation with the other students and

your own role in it. Think about the following questions:

• What is important for you in a project team? What do you expect of the others in the

team? What would you like to know about them?

• Which role do you think you can fulfill in a project team?

• Try to think of as many aspects as you can. It will make you more aware of your own

ideas about co-operating in an international environment.

3. Write down your personal goals in four specific points and explain them

shortly.

Again think about the co-operation, your own role in a team and the main aim of the

international projects. For example, your personal goal may be that you want to fulfill a

specific role in your team, or that you want to ameliorate your way of presenting. Maybe

you want to pay attention to your English accent or maybe you want to know more about

methods to tackle a problem.

2.2. ASSIGNMENT 1 PART B (NATIONAL GROUP ASSIGNMENT)

Part B is a group assignment for each nationality/school. Each school should find one or

two example cases of a realized stormwater management design in their own country.

The national student groups/schools should each research and prepare a presentation of

approximately 20 minutes (1 example area) or 30 minutes (2 example areas). The

presentation will be presented to the whole group on Saturday on the first weekend.

The following is a suggestion for the structure of the presentations:

1. Introduction of the starting point of the case or cases

a. Issues

b. Goals

c. Limitations

2. Description of material, data and methods in the case/s

a. Material and data and how they were acquired

b. Modeling or other planning tools used

3. Solutions incuding technical and economical considerations

4. Influence of the solutions on…

a. Hydrology

b. Environmental load

c. Landscape and social environment

d. Ecosystem services

e. Adaptation to climate change

It is desirable that the example cases represent the best available technology and practice

in each country. As with all Circle III NEPTUNE projects the balance between development

and environmental factors is a focal issue for this project.

When researching example cases for Assignment 1B students should also be concerned

with the feasibility and/or differences between countries.





3. PRACTICALITIES: Accommodation and travel

Accommodation

The orientation weekend (1.4.-3.4) takes place at Tvärminne (J.A. Palménin tie 260,

Hanko). Students will be accommodated in double rooms (bathrooms in the corridor). The

facilities include e.g. a room with a fire-place, other get-together facilities and self-service

kitchen. Note that Tvärminne is located in the country side and the nearest store or kiosk

is 17 km away.

The rest of the project week (4.-9.4.) the students are accommodated at Forenom

apartment hotel in central Helsinki. The rooms are double rooms with bathroom, amenities

include free high speed wi-fi, an iron, microwave oven, a mini fridge, a coffee maker, a

water boiler, as well as a toaster and dishes.

Locations at the Otaniemi campus

The project work will largely take place at Aalto University, Otaniemi campus at the

Learning Hub Living Room (Vuorimiehentie 2, Espoo).

Participants are encouraged to bring their own laptops and use the free, fast open WiFi

service provided on the Otaniemi campus (and in the hotel).

Travel

Each school is responsible for making the individual air travel arrangements for their own

party. Everyone is requested to travel to Helsinki Vantaa Airport on Friday April 1st, where

we will meet at the main meeting point. Parties are asked to ensure they arrive at Helsinki

Vantaa Airport in time to leave the airport at 6 p.m. A rental coach will then take all

parties from the airport to the orientation weekend resort at Tvärminne in Hanko (travel

time ca. 2.5 h).

In the afternoon of Sunday 3.4 the coach will then take us to the hotel at Kamppi, Helsinki.

Students will be required to travel from Forenom apartment hotel in the city centre to the

Aalto University campus at Otaniemi on a daily basis by public transport (bus). The journey

takes about 20 minutes. Free travel passes will be arranged for students. See additional

details below on using public transport.

After the week, transfer back to Helsinki-Vantaa Airport is under own arrangements. It is

advisible to take a train from the main railwaystation (800 m from hotel) to the Helsinki-

Vantaa airport. The train ride takes about 30 minutes.

The costs of accommodation and all meals for student participants are covered by Aalto

University. Partner schools’ students need to pay a contribution of 250 Euros. For domestic

students this contribution is 150 Euros.

Registration and payment information will be informed later.

Things to pack

The accommodation at Tvärminne station is rather basic. You will be provided with sheets

and a towel, but there won’t be e.g. any complimentary toiletries. There will be a possibility

to go to sauna. At Tvärminne, the nearest store/kiosk is 17 km away.

4. CONTENTS OF THE PROJECT

More information will be posted on MyCourses portal once the course starts.

Kumpulanpuro in a nutshell

Cachment area: 5,1 km2

Length: main channel 1,9 km, of which

o < 25 % piped

o > 75 % open channel

o Length of all channels: 15 km

o Storwater sewers: 63 km

Average flow: 46 l/s Outlet: Vanhakaupunginlahti

Kumpulanpuro catchment area

Kumpulanpuro starts from Mäkelänkatu, flows through the green valley of Vallila and drains

into the Vanhankaupunginselkä bay. The catchment area includes e.g. the railway yard in

Pohjois-Pasila in the north, dense commercial and residental area Itä-Pasila, parts of

Käpylä residental area with both multi-storey block and small-house areas, allotment

gardens, storehouse area and also a lot of green area.

Kumpulanpuro is located ca. 3 km from Helsinki city center in a central location for many

different land use types. The general area has high cultural value and is at the same time

under development pressure. The new land use master plan (yleiskaava) proposal for

Helsinki places great importance on new housing for the rising population. The master plan

proposal enables the building of new tramline and railway running through the valley of

Vallila.

The stormwater related issues at Kumpulanpuro include flooding and poor water quality.

There has also been challenging debate between the city and a local residents' association

about new stormwater development plans for the area. At its current state, the water

quality in Kumpulanpuro is too poor for recreational use or for use as irrigation water on

the garden allotments.





Figure 1. Kumpulanpuro catchment area.

The catchment area can be explored on the Helsinki city mapping service which has a lot

of information about the environment, land use, planning etc. (also in English) -

http://kartta.hel.fi/#

Previous stormwater management plans

The city of Helsinki has presented the following future vision for Kumpulanpuro:

More environmentally friendly city stream with better water quality. Retention

and biofiltration of stormwater from Itä-Pasila by means of, for example,

retention ponds and raingardens. (HKR 2007)

In 2012-2014 the city made comprehensive stormwater development plans for the area

including two retention and filtration ponds. Unfortunately the plans were met with great

resistance from the local residents' association and the construction work had to be

canceled. The residents' association gathered an expert group to make an alternative plan.

http://kartta.hel.fi/





Solutions

The final goal is to present plans, ideas or concepts that deal with the main issues in

Kumpulanpuro catchment. The main issues are:

Water quality

Flooding

Contradiction between planners and residents view of stormwater management

methods

The solutions may encompass some of the following issues or themes:

o Flooding & other hydrological responses

o Environmental load, water quality

o Mixed (wastewater and stormwater) sewers

o Landscape and social environment

o Ecosystem services

o Environmental management

o Adaptation to climate change

Stormwater management in general

Stormwater generated in urban areas can have a significant impact on the nearby waters.

Sustainable management of urban waters reduces occurence of floods, erosion and

environmental loading. It also increases groundwater formation. In addition to reducing

environmental loading, sound management of stormwater sustains healthy, comfortable,

and functional city environments. The management of urban waters requires consideration

of techno-economic, ecological and social issues and it must be based on research

information from the local climatic conditions.

Compared to natural areas, built areas have a significant fraction of impervious surfaces

and thus a fast draining system. This leads to hydrological changes in urban areas: the

volumes of surface runoff and peak flow increase and rain events have flashier responses

in the receiving stream. The larger and faster variations in stream flow result in decreased

stability of channels and increased level of erosion. The changes are manifested through

shifts in infiltration, filtering, storage capacity, detention and evapotranspiration of water.

In Finland more than 90% of the urban drainage systems are separate sewer systems

where stormwater is conveyed without any treatment directly to the nearest receiving

water body. As a consequence, pollutants originating from urban surfaces (traffic areas,

roofs) are also flushed with stormwater to the nearby waters. Typical pollutants found in

stormwater include suspended solids, nutrients, heavy metals, oil and bacteria.





On the other hand, mixed sewers, where stormwater is conveyd to the sewer system,

cause significant and problematic volume loads of water at wastewater treatment plants

during rain events. This can results in overflows and bypassing of wastewater at the

treatment plant.

Stormwater modelling

Environmental modeling of any kind should ideally always consist of a rigorous calibration

and validation procedure. In stormwater management the input data is highly detailed and

thus modeling can be time-consuming. However, it has been debated that sufficient results

could be achieved even with low spatial resolution non-calibrated models. Alternatively we

may get to use a previously constructed computational model of the area.

The EPA Storm Water Management Model (SWMM) is one of the most commonly used

stormwater management models. It is free of charge and can be downloaded from:

http://www.epa.gov/water-research/storm-water-management-model-

swmm#downloads

For example, Aalto University master’s thesis by Tikkanen (2013) provides clear

explanation of the SWMM hydrological components: precipitation, evapotranspiration,

infiltration, snow and snowmelt, surface and subsurface flow. This master’s thesis can be

found at:

http://civil.aalto.fi/fi/research/water_and_environment/theses/water_engineering/

(in English).

Wastewater treatment

Wastewater in Helsinki is treated at the Viikinmäki treatment plant, the largest wastewater

treatment plant in the Nordic countries.

We will be hosted by Helsinki Region Environmental Services

Authority HSY on a guided tour on the extensive Viikinmäki

underground treatment complex (270,000 m³ of wastewater

per day).

APPENDIX 1 – Additional information on practicalities

Using Public Transport

As students will be located in downtown Helsinki they will need to travel to and from

Otaniemi campus on a daily basis. Here are some general instructions about using public

transport in the Helsinki metropolitan area.

The capital region of Finland consists of three major towns: Helsinki (where the main train

and bus stations and all harbours are located), Vantaa (where the airport is located) and

Espoo (where our university and campus are located). The public transport pass issued to

you allows you to use all kinds of transportation (bus, train, tram, underground) in all three

cities.

The buses from Helsinki to Otaniemi leave from Kamppi terminal (Kamppi is also the name

of the district). The terminal is located in Kamppi Shopping Center, and the bus platforms

are inside the building. Everyone in Helsinki knows Kamppi and almost everyone speaks

English, so you can just ask your way there if you get lost!

Getting to Otaniemi campus from Helsinki City Centre - To get to Otaniemi, we

recommend buses 102, 103T or 103. They leave from Kamppi (platforms 41 and 42)

with stops very close to both the Forest Products Technology Department and the Water

Laboratory. The bus ride takes about 20 minutes.

There’s a great route planner for time tables etc. http://www.reittiopas.fi/en/
