"Municipalities as integrators and coordinators
in adaptation to climate change"

Inventory list

The Inventory list collects the developments, products and services which can provide ecosystem-based help to the municipalities to solve regional or local climate change-related water issues. The collection contains the basic data for the ecosystem based water management, the availability of the relevant experts and providers, and the list of certain developments, products and services. The list will be regularly updated during the LIFE-MICACC project.

Solution 1: Waterproof Cover

Solution Description: The purpose of a water-permeable casing is to allow rainwater to seep through the surface and enter underground layers or underground storage, which helps to release it to surface water in a controlled manner. We distinguish 3 types:

Completely permeable to water: Almost all rainwater passes through the casing into the substructure or into the ground without any surface water retention.

Partially permeable: perforated pipes are located between the substructure and the subsoil, which help to transfer water in excess of the capacity of the soil into a temporary storage tank.

Impermeable: Perforated pipes lie between the substructure and an impermeable layer so that all rainwater passing through the enclosure enters a reservoir and does not seep into the soil.

All three solutions mitigate the damage caused by heavy rainfall and, when properly applied, can store excess water. The first two solutions drain rainfall into the soil, contributing to the rise in groundwater, which in some cases can lead to landslides. The third solution does not disturb the groundwater, but stores the overflow and then releases it into the environment at a controlled rate. However, its capacity is finite.

Solution 2: Restore Stream Beds to their Natural State

Solution Description: By stream or riverbed, we mean the base of a stream, including river banks. In the past, many beds have been artificially lined with concrete or rocks, modifying flow parameters and reducing the local fauna and thus the diversity of vegetation. Interventions were generally aimed at preventing floods and serving agricultural interests. This standardized the speed of the watercourse and often reduced the time traveled on the river. During the restoration of the beds to the natural state, the concrete foundation and all artificial artefacts are removed and natural substitutes are used to help restore biodiversity. This intervention can help to seriously slow down the erosion process. The most important element of this is the application of different stabilization techniques. The greatest effect is achieved by restoring the vegetation cover and the naturalness of the stream bed during the operation. This is usually done by planting plants. The techniques can be divided into two groups based on their complexity:

Restoring the coast to natural state: This process does not require any serious expertise and is aimed at stopping the mid-level erosion processes.

Plant Engineering Interventions: The technique combines ecological and engineering principles to restore beds, shores and slopes using plants as the raw material that form a living frame around the problem area.

Solution 3: Rewind

Solution Description: River bends, which are generally U-shaped, significantly reduce the flow rate. In the past, they were often artificially straightened by cutting corners. The purpose was generally to facilitate and speed up river navigation, to protect against floods and to cultivate new areas. During the rewinding process, the cut parts are reconnected to slow down the flow. This has positive effects such as increasing biodiversity and restoring natural sedimentation. These revitalized areas can provide home to a great many aquatic and terrestrial organisms.

Solution 4: Removal of Dams and Other Crossing Obstacles

Solution description: Dams and other man-made structures are obstacles that separate the river's natural wildlife and cause serious problems with sediment management in the vicinity. Removing them can restore natural flow directions as well as the natural dynamics of sediment and wildlife.

Solution 5: Remove artificial river banks

Solution Description: Artificial river banks help control the movement and changes of the river bed, while preventing the water from laterally connecting to its surroundings. Even partial removal can help the appearance of natural flow directions and dynamics and reduce the risk of flooding. This measure is a prerequisite for several other water retention solutions, such as re-winding or restoring the riverbed to its natural state.

This measure can be particularly effective for large, swollen pebble bed beds, where pebbles are continuously washed away by water and lack slow-flow protected areas suitable for aquatic life. These areas are extremely important for river fishing, as the spawning habits of many species are linked to these habitats. However, this is one of the most difficult measures to implement, as artificial shores are often linked to shipping, power generation or flood protection interests.

Solution 6: TerraWay® Enclosure

Solution Description: The TerraWay® paving is a mixture of synthetic resin and gravel or rock chippings specially developed for the pavement of walkways and light-traffic roads. Its surface is hard, well-traveled, non-slip and durable. The TerraWay® cover is completely permeable to water: it transfers the falling rain to the substructure, where it drains into the ground, and lets upward uppermost soil. Due to this property it can be taken into account in the calculation of the green area.

Its main fields of application are: sidewalks, park walks, car-paths, bicycle paths, walkable roofs, roof gardens, swimming pools.

Technical characteristics, environmentally friendly features:

- strong, durable and durable surface

Solution 7. Elaborating a concept for precipitation management and adapting to climate change in the settlements of Tát and Tokod, Hungary

Programme objectives

Based on observations concerning climate change and the results of regional climate
models it is likely that the tendency of warming will continue in Hungary in the 21st century.
The quantity and distribution of precipitation is expected to change. As a consequence, reliable and scientifi cally-based knowledge is needed to promote the elaboration of adaptation
strategies and to facilitate decision-making targeting adaptation. The present pilot project
aims to enhance resistance towards the effects of climate change and to promote adaptation, focussing on a pre-defi ned area around the settlements of Tát and Tokod in Hungary.
In these settlements and the neighbouring area problems are caused mainly by high
levels of ground water, extreme and big amounts of precipitation and unexpected fl ows of
water due to the already terminated mining activity. The programme provided support for
tackling these issues also in the form of constructions.

Simulation model

One of the major innovative elements of the project is the methodology applied in professional activities, more specifi cally, the application of a simulation model to map the inter-related processes that characterize water-fl ows in the drainage network and infrastructure of
the settlements. The simulation model elaborated in accordance with the objectives of the
project may be an example to be followed in other settlements with a similar topographical,
morphological environment and climate.
In the framework of the project a planning guide was also elaborated for the catchment
area and the territory of the two settlements of Tát and Tokod. The aim of the guide is
to support planning experts and promote a more accurate planning of local infrastructure,
showing the system-level impact of different precipitation events. A range of model varieties were developed to simulate different weather scenarios, and these scenarios were
then used to elaborate measures that the local governments may implement to tackle the
settlement-level issue of precipitation management in a wider context, covering the catchment area around the settlements. The elaboration of the simulation model was assigned to
an external research team, DHI Hungary Ltd. (www.dhi.hu)

 Development at the settlement of Tát

Problems caused by precipitation and ground water In a major part of the settlement precipitation is managed in drying ditches, and only a minor part of water is directed into a closed system. In average weather conditions the ditches are appropriate. However, they fail to function whenever the water-level of the neighbouring river Danube is high and heavy rains lead to increased levels of ground water. Such occurrence of extreme weather conditions led to a critical situation of fl ooding in the eastern part of the settlement of Tát-Újtelep in 2010. The problem was further aggravated by the big amount of precipitation fl owing into the sewage system of Tát from the settlement of Tokod, because the dirty water pushed up the covers of man-holes in the streets and fl ooded residential areas. Since 2010 ground water has caused more and more problems in residential buildings due to the lack of proper insulation. The situation is expected to improve considerably after the closed system of precipitation management becomes operational in the whole settlement.

 Constructions implemented

The precipitation draining ditch in the area called Falu-alja is fi nished. Precipitation management is permanently solved by the construction of a partly open, partly closed precipitation drainage system and a link connecting the system to the ditch of the stream called Unyi patak. The existing precipitation draining system was also renewed. Overall, a 12 km long section of the system was cleaned and reconstructed by replacing the damaged covers of ditches in 31 streets in the settlement. Elaborated plans The precipitation management plan of the area called Tát-Kertváros is fi nished, and the plan received the offi cial license of the water management authority and can be implemented. An infrastructure development plan was also elaborated for an area of 20 hectares in the most critical part of Tát-Kertváros, the area around Nefelejcs street.

Solution 8: The drainage system of Győr-Szabadhegy, Traktoros utca

In 2010, a new drainage system was installed on Traktoros Street, which solved surface water disposal to prevent major storms from damaging the area and separating rainwater from sewage. Rainwater is directed towards Adyváros Lake. The project was the third phase of the complex reconstruction of drainage around Szabadhegy. While the first two phases (construction of the main pipelines and canals of Pannónia Street, drainage and paving streets of Vak Bottyán Street) were financed by the municipality, the third phase was implemented with the help of the EU.

Project goals:

- protection of the built environment: safe disposal of rainwater - environmental protection: distributed drainage system for rainwater and sewage

Execution activities:

A 647 m new drainage system has been implemented, which includes the complete renovation of Traktoros Street drainage, partly the renovation of Virág Street, Mozsár Street and Levendula Street (Reference 3) - installation of canals and reconstruction of 30-40 year old drinking water supply pipes - renovation of Traktoros Street and 80% of side walks.

Solution 9: Inland water development in four districts of Győr with county rights

Purpose of the tender

Increasing the environmental safety of the settlement, improving its environmental condition, reducing the risk of inland and local water damage, improving the quality of surface waters, and preventing further environmental damage. Our main objective is to drain rainwater in the inner area in an orderly and harmless manner. In addition, the aim is to increase the comfort level of the population, thereby facilitating attachment to the place of residence and staying in place.

Description of the project

1. Project component - Adyváros
Adyváros City No. 1 The reservoir is an important part of the triple lake system that serves the drainage of the Adyváros and Attila József housing estates (rainwater receiving, reservoir and runoff retention lakes). It has long been a major demand of the population to tidy up the environment of the reservoirs, since in addition to the function of stormwater in the housing estates, these lakes also serve as public spaces for active recreation.

In the current project, no. the reservoir is dredged with dredged vegetation beds, and the obsolete artefacts built in the lake system are not able to perform their function perfectly in their present state. A common problem during the summer is the frequent death and stinking of fish, which greatly disturbs the inhabitants of the lake.

In the course of the reconstruction, 10-30 cm seabed sediment in the lake will be removed and the introduced vegetation will be thinned out. The reconstruction of the object requires the construction of an additional 1 piece of art. Removal of existing cleaning heads will result in the removal and relocation of existing drainage heads due to installation and sewerage. The capacity of the reservoir will increase to 32.166 m3 following the intervention.

2. Project component - Szabadhegy
It is aimed at the construction of rainwater drainage (road construction) sections on the Gyöngyvirág-Mozsár-Kopja street section of Szabadhegy. In the years 2006-2010 the first four-phase construction of the rainwater drainage system of the Győr-Szabadhegy part of the city was the first to be built in the receiving area of ​​the rainwater of Adyváros. backwater pipeline and oil separator to deliver the reservoir. II. In 2009 the drainage and pavement renovation of Vak Bottyán utca, III. Phase I was completed in 2010 as part of the sewerage of the sections of Traktoros Street and some surrounding streets and the reconstruction of the pavement. In III. as a close continuation of Phase IV. The phase includes the construction of the sewerage section of Gyöngyvirág Street, Lepke Street, Mozsár Street, Mozsár Street, Virág Street and Gábor Áron Street, Kopja Street, between Traktoros and Mozsár Street. In Gyöngyvirág Street the demolition and reconstruction of the existing sewerage system must be done in the opposite direction of the flow and the bottom of the riverbed, because only this solution can ensure the sewage connections of the family houses. Following the construction of the canal, the pavement of the streets will also be renewed. The intervention is 527 m long. 100% of the road is being reconstructed from municipal sources.

3. Project component - Gyirmót - Ménfőcsanak
The regional development and the building conditions of the past years have made it necessary to make the drainage of the parts of the city a high priority in the development program of the city. The project involves the reconstruction of the Gyirmót-Ménfőcsanak watercourse.

During the reconstruction of the approximately 3.5 km canal, the removal of aquatic vegetation in the riverbed, significantly deteriorating the runoff conditions, sludge dredging, restoration of degenerate riverbed sections, and renovation of existing structures and construction of new ones.

As a result of the planned intervention, the drainage capacity of the riverbed will be improved, the chance of rapid re-vegetation of the riverbed will be reduced, and free storage capacity will be replaced by the extracted sludge.

4. Project component - Kisbácsa
In the Kisbácsa part of the city, the section between Külső-Bácsai Street between Csemete and Boglárka Street, Boglárka Street between Külső-Bácsai Street and Sövény Street, the section of Sövény Street between Boglárka and Csemete Street, within the project.

In 2010, the New Bácsai Road was commissioned, the construction of which ensured the receiving of the rainwater of the Győr-Kisbácsa district, thus technically creating the condition for the area's water management to take place. In the first phase of the project, the backbone of the rainwater drainage system will be constructed, which can ensure the further development of the system. The bottom of the Szabadság Street - Sövény Street intersection will be connected to the backbone, which will result in a noticeable improvement immediately. The related road construction works will be 100% self-financed.
