Abstract:
The data on the maximum river runoff are extremely important because they help determine a number of dimensional characteristics of the hydrotechnical facilities, the magnitude of the high wave for the purpose of flood protection and others. Frequently, in hydrological practice, there is no data from its immediate observation. We investigate the possibility of recovering the maximum outflow data on the average runoff data. Some Bulgarian river catchments were investigated. Several correlation coefficients have been calculated. The closest is the relationship between the maximum monthly water runoff and the average monthly water runoff.Download article
