restoration measures at the
lowland river Morava
pilot project “MUF km 15 –25” river bank

3. introduction pilot
planning process pilot project monitoring
1.step - general scheme with
following goals:
development of various types of
measures, related to different
objectives in the context of river
ecology
2 – phase plan
phase A – short term goals
phase B – long term “ideal”
objectives
2. step – application of types of
measures for the river section km
15 - 25

typology of measures
A. improvement of river
course development
B. variability of cross section
morphology
C. lateral connectivity

structures in river course
F. new types of river bank
stabilization
G. design of river banks in urban
