  1. 1. introintroduction planning process pilot project monitoring restoration measures at the lowland river Morava oberhofer riocom
  2. 2. introduction planning process pilot project monitoring restoration measures at the lowland river Morava pilot project “MUF km 15 –25” river bank and river profile improvements and restoration as well as measures for meander reconnection for the Morava River km 15-25 (Marchegg). oberhofer riocom
  3. 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 oberhofer riocom
  4. 4. 1st phase 2nd phaseintroduction planning process pilot project monitoring 2 phase plan oberhofer riocom
  5. 5. introduction planning process pilot project monitoring typology of measures A. improvement of river course development B. variability of cross section morphology C. lateral connectivity D. meander reconnection E. improvements of low water structures in river course F. new types of river bank stabilization G. design of river banks in urban areas oberhofer riocom
