This document is focused on the structural features of rivers, on geomorphological and hydrological processes, and on river continuity. It provides guidance on the features and processes to be taken into account when characterizing and assessing the hydromorphology of rivers. It is based on methods developed, tested, and compared in Europe. Its main aim is to improve the comparability of hydromorphological assessment methods, data processing and interpretation. Although it has particular importa...view more

This standard considers liquid precipitation and defines a classification for catching-type RI measurement instruments based on their laboratory performance. Standardised calibration tests are described for the assessment of the accuracy of these raingauges both in the laboratory and in the field. The classification does not relate to the physical principle used for the measurement nor does it refer to the technical characteristics of the instrument assembly. The classification is solely based o...view more
