ABSTRACT
Selection of a proper site and parameter dependent calculation method is important. For Danish streams and rivers regressional methods result in the highest accuracy, if measurements indicate a safe CQ-relationship. Annual transport have an uncertainty ofaproximately 5% and monthly transport 10% by regressional methods. C.-intp. method result in uncertainties of 10% (annual transports) and 20% (monthly transports). Trapez method, however, are connected with uncertainties of 20% (annual loads) and 50% (monthly loads). Above uncertainties are valid for aproximately 12 samplings per year.
