About the archive

In 2012 we lost Jean Jacques Peters, former engineer of Flanders Hydraulics Research (1964 till 1979) and international expert in sediment transport, river hydraulics and morphology. As a tribute to him we have created potamology, a virtual memorial archive whose aim is to preserve and disseminate his way of thinking and his morphological approach to river problems all over the world.
This archive provides four modules, each with its specific information set relevant to Peters’ work. Where available and if not confidential, there will also be access to the full text. In dialogue with Peters’ family we continue to make his life’s work accessible.

Abstract
    The sedimentation zone of the maritime reach of the Zaire river located upstream of the canyon is described. The main characteristics of water and sand movements are indicated: stable regime and large discharges ranging from 23000 m3.s-1 to 80000 m3.s-1; low tides at the mouth with an average amplitude of 0.80 m, quickly damped upstream; sand of the bed with grain sizes dropping downstream from 1 mm to 0.2 mm, moving generally as dunes with a speed of 2 m to 10 m per day. The apparition during floods of different and smaller scale bedforms was observed. Measuring and calculation techniques are briefly described. Some results show the influence of geomorphological factors on sand transport phenomena, the erratic variations in time and space of sand transport rates and the influence of tidal movements on these. The role of secondary currents on the distribution of sand transport in and between channels is emphasized. Volumes of water and sand evacuated annually through the braided area are respectively estimated at 1.45 X 1012 and 50 X 106 m3.
