 The approach to analyse the appropriateness of the measure 'river-in-river' would be after a diagnosis of the total system has been performed and the limiting factors identified. In the case where habitat is a limiting factor, 'river-in-river' should be considered as a measure. This measure would require that the river is sufficiently wide to allow a meandering structure of the river. The flood capacity of a modification of the river bed should also be carried out, to ensure that the bypass section of the river has similar conveyance capacity after the measure is put in place.
-Hydraulic tools are useful in analysing the hydraulic conditions in a river, before and after modifications. A high number of hydro-dynamic and hydro-morphodynamic tools are available for such analysis with different functionality and data needs, ranging from more simplistic 1-dimensional (1D) hydraulic tools, to highly advanced 3-dimensional (3D) tools solving a range of partial differential equations (Navier-Stokes) in all directions. They all require detailed description of the bottom topography of the existing and planned river, and a flow regime the river will undergo. As average flow velocities (in depth and across the river) will not be sufficiently detailed to identify the best locations, 2D- or 3D models will be required. Examples of such models are River2D, HEC-RAS 2D, Flo2D/3D, Mike21c, OpenFoam and Telemac 2D and 3D (see Chapter 9.1 for references).

 Habitat measures in regulated rivers must often be maintained unless the natural functions related to flow and sediments are restored, such as flood events and connectivity of the sediments. The frequency of the maintenance will be very site-specific.
