In 1951–52, a nationwide sediment gauge network was initiated in Bulgaria. In 1992–93 a Computerized Information Base of Sediment Data for the Bulgarian rivers was developed. Some analysis has shown that the long term sequences of the annual suspended sediment load of the rivers are not homogeneous. The period 1980–90 has received special attention due to the anthropogenic generated randomeness of the hydrometeorological process on most of catchment areas across the country. Due to the anthropogenic impact, the sediment load assessments are strongly affected. The author has determined a new parameter — Partial Suspended Sediment yield — MR(°) that is formed in separate river reaches, bordered by any two adjacent gauges. The partial suspended sediment yield is zoned in selected grades instead of drawing isolines. A comparison among runoff (Q) and suspended load (R) for the rivers in Bulgaria reveals relationships that are in conformities with the process of suspended sediment formation. Some other empirical relationships of potential practical use for the Bulgarian rivers have been determined. The goal is to introduce some results of Bulgarian sediment studies to a Non-Bulgarian audience.
