may presumably be a longer watering period in summer and higher drainage demand in
winter with concurrently less discharge ability due to sea level rise.
The deepening of the river Weser (Fig. 6.13), accompanied by a further upstream salt
incursion of the river water, might reduce the availability of fresh water. Consequently, the
watering and drainage system has to be adjusted and alternative solutions to solve these
problems have to be discussed. Different sectors will be influenced by changes in water
management such as agriculture, nature conservation and tourism.
Solution Options
Based on the results of the former EU Interreg IVB project Climate Proof Areas (CPA)
solution ideas were jointly developed by the regional forum Wesermarsch
8 (Ahlhorn et al.,
2011). Based on these results an investigation was started to enhance the list of possible
solution ideas for the watering problem in the county of Wesermarsch. In the context of the
EMOVE project this investigation has been conducted by applying the DPSIR approach.
According to the DPSIR approach the identified solution ideas were named responses. The
outcome of the investigation within the EMOVE project and the entire list of responses can
be found in EMOVE Project (2015).
The main focus for the drainage boards is to improve and ensure watering and drainage is on technical solutions. For example, the extension of the Butjadinger canal to the
south of the tidal gate Beckumer Siel, for example, down to the tidal gate Käseburger Siel
(Fig. 6.12), hence, enlarging the existing watercourses. The water could be stored, distributed, and transported over a longer distance and could be available for a wider area for
watering purposes.
This measure would affect different drainage boards, which supports the idea to reorganize the watering and drainage system across the northern drainage boards and to have
trans-boundary cooperation between these boards. In the meantime, a joint venture has
been established between the three drainage boards of Butjadingen, Stadland and Brake
called Planungsverband Wesermarsch (Planning Association Wesermarsch).
To guarantee the livestock drinking water supply in summer time the existing drinking
water system could be adjusted to the increasing demand. This means using high quality
water to feed the cattle. A combination with water storage in winter time in reservoirs, for
example, constructed close to the Beckumer Siel, might be a possible solution for having
enough water in summer.
Associated with the currently planned fairway deepening of the Weser is an avoidance
solution for the northern drainage boards in the Wesermarsch. This avoidance solution
comprises an improved steering of the watering features and the heightening of the dikes
around the Butjadingen canal which is feeding the fresh water into the drainage board
areas up north.
8 The regional forum was a stakeholder forum consisting of various representatives from different
sectors such as agriculture, water management, spatial planning and nature conservation.
