1. General information
2. Objectives of the intervention
Goals of the intervention
The goals of the intervention:
1) To renaturalize the river shore and to create habitats for the typical local flora and fauna;
2) To improve the experience and attractiveness of the river landscape;
3) To increase biodiversity;
4) To create a sand beach and a lively and attractive space for walking, playing and resting;
5) To improve the possibilities of nature observation and access to the river water;
6) To protect the shore from severe erosion by the waves (Ref. 1, 2, 5).

Quantitative targets
Renaturation of the river shore on the area of approx. 5 ha (Ref. 1) [Ref. 5 indicates 74 000 m^2].
The section of the river between Fuldahafen and Hemelinger Sporthafen to be redesigned at a length of approx. 100m to a natural sand bank with a flat slope;
Development of a near-natural river bank in the area of the "Landzunge", with the terrain above the changed water zone to be removed on a width of approx. 100 m;
Creation of a 130 m long bank strip with flat water zone (Ref. 2, 3, 4).

Implementation activities
Restoring the river bank structures by measures: 1) The section of the river between Fuldahafen and Hemelinger Sporthafen to be redesigned at a length of approx. 100m to a natural sand bank with a flat slope; 2) Developing a near-natural river bank in the area of the "Landzunge", with the terrain above the changed water zone to be removed on a width of approx. 100 m; 3) Creation of a 130 m long bank strip with flat water zone; 4) Creation of a natural sand beach; 5) Removing the existing, fortified bank structures (stone bedding) above the middle tidal low water line; 6) Clearing the natural sandy soil layers and converting them to near-natural sand banks with shallow water zones (Ref. 2, 3, 4). "The measures in Hemelingen were carried out in February and March of 2012; the restructuring in Habenhausen was implemented in 2014. Half of the costs were defrayed via funding from the European Regional Development Fund (ERDF), and the remainder from sewage fees." (Ref. 5).
"This measure aimed for the following: reinstatement of links between floodplains and the Weser federal waterway; hydromorphological improvement; making the area conducive to tourism and municipal recreation. To this end, 650 meters of Weser riverbank were renatured in the Bremen Hemelingen area and a link was established between the Weser and its floodplain. The Lake Hemelinger peninsula was planed down and watercourses were created that run through it" (Ref. 5).

5. Innovation
Type of innovation
Please specify technological innovation
The project is an infrastructural innovation that through various renaturation and redevelopment works at the river's shore creates both new habitat for species and an attractive urban recreational area at the water (Ref. 1, 3).
Novelty level of the innovation
Please specify novelty level of the innovation
The project is a part of the wide-scale renaturation initiative of various parts of the Weser river in Bremen-Hemelingen (Mittelweser / right Weser's shore, 2010 - 2012) and Bremen-Rablinghausen (Unterweser / left Weser's shore, 2008 - 2009), as a part of the project "Lebensader Weser" (Ref. 4).
