Monitoring of the ice jamming process in rivers using spatiotemporal plots of the water levels

A methodology of plotting of the water levels along a river and its using for (1) finding places where ice jamming is possible, (2) estimation of the maximum levels caused by jams, and (3) estimation of risks of flooding in ungauged river sections is presented. For the Northern Dvina River case study, isolines of the 2003 river flood levels are plotted for the entire river length and places of possible jams are defined by using the proposed approach.

Regional estimation of peak rainflood discharges

Presented are the results of statistical estimation of peak rainflood discharges of the Middle and Lower Amur basin rivers during the period from the beginning of observations to 2007. On the basis of prolonged observation series probable water discharge values were computed and the analysis was carried out of the 1%-probability flow modulus areal reduction. Specified were the 1%-probability peak (maximum) rainfall flow modulus values for the small river catchment areas.
