Suspended sediment production in a suburban tropical basin (Lubumbashi, Zaire)

Abstract: A study of suspended sediment transport in the 8.5 km 2 River Lubwe catchment was carried out during the wet season [1983][1984]. The suspended sediment yield was estimated using the suspended-sediment rating curve technique and detailed observations of 10 runoff events. The River Lubwe is characterized by periodic high magnitude floods, during which the bulk of the load is transported. The total suspended load for the hydrological year 1983-1984 is estimated at 108 t, representing -2 -1 a sediment yield of 12… Show more

“…This indicates that the major sources of sediment in the J J2 catchment are located nearer the river and the sampling point compared to those in the J J1 catchment. This p h e n o m e n o n (the earlier sediment peak in relation to streamflow peak) has also been reported by many researchers (Loughran, 1976;Walling and Webb, 1982;Lootens and Lumbu, 1986).…”

“…The clockwise hytheresis in the suspended sediment-discharge relationship has also been reported by a number of researchers (e.g. Carson et al, 1973;Walling, 1974;Faye et al, 1980;Walling andWebb, 1982, Lootens andLumbu, 1986). The clockwise hytheresis results when the suspended sediment peak occurs earlier than the discharge peak, i m p l y i n g that the earlier explanations concerning sediment sources also apply here.…”

“…Although the runoff-and sediment outputs from urban construction sites in the tropics are beginning to be documented (Chinnamani and Sakthivadivel, 1985;Lootens and Lumbu, 1986;Douglas, 1999), observations for rural settlements are rare. Darga Talkurputra (1979) noted a positive correlation between percentage surface area occupied by villages and sediment yield for a set of (large) catchments in West Java.…”

“…This falling concentration is unique for these climates and is not 1068 C. D. Guzman et al: Suspended sediment concentration-discharge relationships well understood. Reasons mentioned in the literature claim that sediment available for transport by runoff is decreasing (Nyssen et al, 2004;Vanmaercke et al, 2010;Lootens and Lumbu, 1986;Sharma et al, 1984), plant cover protection is increasing (Haile et al, 2006, and rill formation has ceased . In the Universal Soil Loss Equation modified for Ethiopian conditions by Hurni (1985), the decrease in sediment concentration was incorporated in the C (vegetation) factor of the plants Eweg et al, 1998;Haile et al, 2006).…”

“…For example, runoff coefficients (i.e., the portion of rainfall that becomes runoff) increase during the rainy season (Liu et al, 2008), while mean sediment concentrations fall as the rainy season progresses, in both the semi-arid and humid parts of the highlands of Ethiopia as well as in other countries with monsoonal climates (Vanmaercke et al, 2010;Mulugeta, 1988;Lootens and Lumbu, 1986;Sharma et al, 1984). This falling concentration is unique for these climates and is not 1068 C. D. Guzman et al: Suspended sediment concentration-discharge relationships well understood.…”
