IKoNE: INTEGRAED WATER MANAGEMENT IN THE NECKAR RIVER,

    BADEN-WURTTEMBERG, GERMANY

    Karlsruhe University, Germany

Introduction

    In Germany, the federal state governments and local authorities (cities, districts and

    municipalities) are responsible for enforcement of water regulations. The Water 1Resource Administration of the federal state Baden-Wurttemberg reflects the three level

    structure of the state administration in the country. IkoNE project “Integrating Conception

    of the Catchment Area of the Neckar River” is an example from current practices of this

    Administration in integration and coordination between various directions of water

    management within a single river basin, as well as in cooperation between various

    stakeholders. It is performed in the Neckar River Basin. The IkoNE co-ordinates river-

    related measures - structure and quality of the river, sewage regulation, flood protection,

    - with other local and supra-local plans and integrates other sectors planning. Flood

    mitigation is a part of integrated approach to water management within a catchment area

    of a river basin, and this approach is adopted in practical activities of this state. The

    Neckar is the biggest river flowing within the state from its source to its mouth. Its 2catchment area of almost 14,000 km is also located almost entirely in the State of

    Baden-Württemberg, and half of the population of this state live in this catchment area.

    Administrative Structure and Coordination in Water Management

    Germany has a federal structure, which means that governmental tasks are shared between the federal

    and the state governments. The constitution

    envisages that the federal government has the right

    to issue framework regulations relating to water

    resources. The state governments then have to fulfil

    these frameworks by passing their own state

    legislation, and they are also entitled to add

    supplementary regulations.

    Enforcement of all statutory regulations concerning

    water resources, including federal legislation, is the

    responsibility of the state governments.

1 The state of Baden-Württemberg in Germany is one of its 16 federal states. It is subdivided into

    4 Regional districts, each of them having a Regional District Authority. The city of Stuttgart is the

    legal seat of the State Government, the State Departments and one of the Regional District

    Authorities.

administration in Baden-Württemberg reflects the three-level structure of the state

    administration in general.

    Highest Level: Environmental Department with a section for Water and soil. Tasks: Management of water resources administration and general administrative

    procedures.

    Middle Level: Four Regional District Authorities, each of them with a section for pollution control and water resources management.

    Tasks: Water resources management on a regional basis, significant legal procedures in

    this sphere, administrative procedures, counselling services, funding of water resources

    measures taken by cities and amalgamations of cities

    Lowest Level: This level is formed by 35 districts and by those 9 big cities which constitute districts on their own.

    Tasks:

    ? process water resources legislation, provide specialist advisory services,

    monitor surface waters and affluent run-off into these

    ? ground water protection, water supply

    ? sewage/waste water disposal, protection of surface waters

    ? waste management, waste treatment techniques

    ? surface waters, hydraulic engineering, flood protection

    ? land protection, restoration of contaminated sites

Water supply and sewage disposal are part of the tasks of the municipalities. In order to

    cover these costs the water-users have to pay contributions and fees to the municipal

    administrations. They are responsible for the preservation of smaller surface water

    bodies which they own. In Germany, associations play an important role. Usually

    voluntary but in part also set up by the Federal State, they are amalgamations of

    municipalities regulated by contracts. Their task is to manage specific water resources

    problems exceeding municipal boundaries, e.g. water supply, sewage treatment,

    preservation of surface waters and flood protection.

    IKoNE Integrating Conception of the Catchment area of the Neckar River

    IKoNE is an example of the activity of the Water Management Administration of Baden-

    Württemberg. It integrates other partners and coordinates technical procedures in a

    catchment area - not only for flood protection.

    The Neckar is the biggest river flowing within the

    State from its source to its mouth. Its catchment area 2of almost 14,000 km is also located almost entirely in the State of Baden-Württemberg, 50% of the

    population of this State live in this catchment area.

    The Minister for Environment of Baden-Württemberg has given the go-ahead for IKoNE in 1999 which

    consists in a river-basin-related action framework concerning water resources management for the

    entire catchment area of the Neckar river including its

    affluents. Thereby planning and acting of water

    resources management in the catchment area of the

    Neckar river are provided in a synoptic way, taking into account also the requirements of the European

    Union framework Directive about water.

    Basic Idea of IKoNE

    As action framework concerning water resources management, IKoNE co-ordinates

    river-related measures - flood protection, structure and quality of the river - with other

    local and supra-local plans and integrates other sector plannings. The objective is to

    preserve and improve the rivers as living spaces and lifelines of the landscape as well as

    important natural factors for business locations. IKoNE addresses citizens, industry and

    business, associations and authorities, thus all parties living at the Neckar river and its

    affluents and feeling responsible for this region. In a joint responsibility for today's and

    future generations, preservation of nature and use by humans have to be brought into

    harmony.

    In order to achieve a broad acceptance of the action, the objectives of the water

    management administration must be anchored into the awareness of the general public.

    This requires to know about and to understand the complexity of water resources

    management. IKoNE aims at achieving its objectives basing on the following principles:

    ? acting from a synoptic view

    ? orientation by joint objectives

    ? partnership of all participating parties IKoNE is not construction and investment program, but a tool for preparing the

    realisation of such programs.

    Action programs of IKoNE

    IKoNE defines and bundles the multiple tasks of river management into action programs.

    This includes measure-related action programs and fundamentally-orientated action

    programs. The latter serve to gather and make available water resources management

    data. Within the action programs, the following specialised objectives are formulated:

    ? Flood management

    ? Management of flood endangered surfaces and catchment areas

    ? Technical flood protection

    ? Flood damage prevention

    ? Quality of the waterway:

    ? Target Quality Class II slightly polluted

    ? State-of-the-art sewage installations

    ? Structure of the waterway:

    ? Eco-morphology

    ? Minimum run-off

    ? Permeability

    D3 ”Environmental Risk Management in Large River Basins:

    Overview of current practices in the EU and Russia”

By means of this action programs and the framework conditions which have to be taken

    into account, conceptions are elaborated for the entire catchment area of the Neckar

    river and its affluents e.g.:

    ? Conceptions for flood protection

    ? Conceptions for waterway restoration

    ? Conceptions for waterway development

    On the basis of these conceptions the planning authorities of State and municipalities

    elaborate concrete action procedures and construction projects.

    Working methodology of IKoNE

    Within the work of IKoNE, the concept "integrating" means the following:

    ? The entire catchment area is considered.

    ? All subjects of water resources management are considered in a synoptic

    way.

    ? The interdisciplinary approach ensures that also other subjects are

    integrated.

    ? The expectations of the population concerning the living space of the river

    with its recreation and leisure function

    ? All partners from within the administration and from outside as well as the

    task promoters are involved. Besides the traditional administrative work, communication is of special importance

    within IKoNE. The communication within IKoNE should

    ? Present the water resources management with its tasks and objectives in

    a convincing way.

    ? Create confidence.

    ? Influence behaviour.

    ? Win co-operation partners.

    IKoNE provides a guiding tool with agreements upon objectives for the catchment area

    of the Neckar river from which environmental, technical and financial priorities can be

    deduced. IKoNE is an agenda for politic, administrative, scientific and private action for

    the sustainable management and development of the waterways in the catchment area

    of the Neckar river.

    All responsible and participating parties can use these documents.

    The IKoNE handbook 4 describes flood management with all its components with the

    joint objective of reducing flood damages.

    A tool developed jointly by research and administration within IKoNE which should

    support the all-encompassing flood management:

GIS-supported flood modelling by

    the example of the Neckar river

    Fig. 9: GIS-supported flood modeling

On request of the Water Management Administration of Baden-Württemberg, the

    Institute of Water Resources Management, Hydraulic and Rural Engineering (IWK) of

    the University of Karlsruhe has developed in the context of the program IKoNE a GIS-

    supported flood model for the Neckar river. The model is transferred to the water

    management administration of Baden-Württemberg with the goal of supporting the

    handling of flood-related issues (determination of legally defined flood areas, analysis of

    flood protection level, risk analysis etc.). GIS-functionalities and user interfaces that are particularly aligned with the needs of the administration have been developed. In

    addition, training courses are organised.

    The project is a positive example of the successful co-operation of the water

    management administration of the State with research and the waterways and shipping

    administration of the Federal Government. This network has been substantial for the

    success of this project. By this means it was possible to create sustainable co-operation

    relations, a realistic requirement profile for the needs of the water resources

    administration, an effective data and know-how transfer as well as transparency for all

    involved parties and users.

    The model has proved to be very useful: overflow scenarios have been visualised in

    such a comprehensible and convincing way that municipalities could be induced to take

    measures for flood protection and damage prevention before a damaging flood took

    place and not only after having experienced material flood damages.
