Factors influencing drift transport and concentration in a second-order high altitude tropical river in central Keny

Abstract

The factors that influence drift transport and concentration in the Naro Moru River are recapitulated. The most important variables accounting for the highest proportions of drift transport variance are volume sampled by nets per 2 h (r=0–72, P</i>< 0–05; a± 95%CL= 1658.3 ± 1388.1, b±95%CL=2.2 ± 1.0) and water velocity at net mouth (r=0.71, P<005; a± 95%CL= 1668.6 ± 1469.7, b± 95%CL =5515.8 ± 2439.8).

Starting with the factor with the greatest influence on drift transport, the following hierarchical rder of factors is established: VOS1>VEL>DIS>VOS2>TRB>DOO>pH>CON>TMP.
