The degree of flood risk is usually determined on the basis of data reflecting the water depth and flow velocity in a given place during the flood event. The result of this procedure are maps of flood areas, flood hazard and flood risk, whose processing arises from requirements of the national and European legislative (the EU Floods Directive 2007/60/EC). Since the above mentioned procedure requires the availability of large amounts of accurate data and their processing, it is currently realizable only on major rivers and a few selected small streams in the vicinity of built-up areas in the Czech Republic. This contribution aims to evaluate the possibilities of hydromorphological data for purposes of identifying the risky areas, susceptible for formation of flood. In combination with data on the nature and extent of the flooded area, the selected morphometric parameters of streams are seen as an effective source of information useful when identifying critical locations. The significance of such a procedure can be seen especially in the watersheds of small streams, for which there are usually no suitable hydrological data and thus determining the extent of inundation areas is not possible. In addition, the impacts of global environmental change in the form of more frequent and more damaging flash floods are increasingly reflected just on the small streams. Therefore the issue is addressed on the example of several small, mutually very different catchments in the Czech Republic. The impact of human activities which affects the natural state of watercourses and thus participates on the shaping the final level of flood risk is emphasized significantly.
