Abstract

SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.

Abstract

In flood risk management, it would be useful to know the upper limit for the maximum precipitation at a specific site. It may be estimated by storm models, maximisation of actual storms or generalised charts. The maximum flood and maximum storm can be derived from the maximum precipitation. Since we are not very sure about these estimates, it is important to prefix ‘probable’ to the terms to emphasise the significant uncertainties with these values.
