General Information
This document gives guidelines for the restoration of rivers, including their channels, riparian zones and floodplains. The word ‘river’ is used as a generic term to describe permanently flowing and intermittent watercourses of all sizes, with the exception of artificial water bodies such as canals. Some aspects of landscape restoration beyond the boundaries of what are often considered typical river processes are also considered.
A clear framework of guiding principles to help inform the planning and implementation of river restoration work is provided. These principles are applicable to individuals and organizations wishing to restore rivers, and stress the importance of monitoring and appraisal. This document makes reference to existing techniques and guidance, where these are appropriate and within the scope of this document.
This document gives guidelines on:
- the core principles of restoration;
- aims and overall outcomes of river restoration;
- the spectrum of typical approaches to river restoration with a focus on those that are nature-based and restore both physical and ecological aspects;
- identifying opportunities for restoration and possible constraints, with a focus on physical and natural rather than socio-economic aspects;
- different scales of restoration and how restoration works across different catchments and landscapes;
- the importance of monitoring and appraising restoration work across the range of approaches and scales.

This Technical Report covers the specific requirements for sampling construction products to determine the release or emission of dangerous substances in their intended use. It is complementary to existing sampling standards and sampling instruction in product standards or test methods for construction products of CEN product TCs and EOTA committees which fall under the CPD.
The scope of this Technical Report covers all activities related to product sampling, starting with the initial planning of sampling until the delivery and formal transfer of the laboratory sample at the laboratory.
This Technical Report:
- does not deal with sub-sampling in the laboratory as a step towards the preparation of the test portion / test specimen );
- does not deal with the second sampling domain in which a sample is to be taken from the air (emission) or water (release) with which the test portion / test specimen has been in contact;
- does not deal with the statistical testing of a construction product against (legislative) limit values, nor does it deal with the definition of repetitive sampling, suitable for fulfilling requirements with respect to a minimum level of uncertainty in a series of test results.
This Technical Report focuses on obtaining a single sample. Repetitive sampling is outside the scope as the boundary conditions for routine testing against a limit are not yet defined (e.g. the necessary reliability). Despite the fact that repetitive sampling is not covered, the conditions provided in this Technical Report apply for an individual sample, as well as for a sample that is part of a series.
