|a Sedimentation is the process of transporting material by water, wind or glaciers erosion
which deposited and eventually become sedimentary rocks. Sedimentation is a frequent
problem in the river basins as it is in active areas with land use activities. These crises
cause the changes and problems to a river basin such as critical sediment production
and on river basin ecosystems deterioration. The main objective in this research to
construct the hydraulic model design in sedimention problems management using the
GIS spatial model and statistical analysis based on the sediment production indicators.
The methodology conducted in this study to obtain the primary data during fieldwork
and secondary data from government agencies for this research to assist about the
sedimentation level analysis and the structure hydraulic model design analysis for
sedimentation problems management in Binanga Aron River Basin. There are main
parameters measured are river cross section (Q) (m³ /s), Total Suspended Solid) (TSS)
(mg/L) and sediment grains size distribution (Phi). The Gravimetric method (USEPA)
used to analyse TSS and the procedure of Gerald & Kenneth and Udden Scale &
Wenthworth were applied in the analysis of sediment grains. Besides that, a spatial
model of the sedimentation was applied using an interpolation tool known as Inverse
Distance Weighing (IDW) in GIS. The results show the highest value of Q recorded
among six stations as 9.79 m³ Is at Station 1 on 2019 and the lowest as 3.17 m³/s at
Station 2 on 2017. Whereas, the maximum increasing of TSS for each year from 2017
until 2019 as 1235.8 mg/l on 2017 to 5400.0 mg/l on 2019. The statistical analysis of
the phi value obtained showed the size of sediment grains is dominated by the rough
size (Phi -0.10 to phi -0.30) and very rough (phi -0.30 to -1.00) which signify the
production of sedimentation behaviour caused by active anthropogenic activities in
Binanga Aron River Basin. The statistical analysis proved the regression relationship
between discharge and TSS and then discharge and sediment grains size distribution
which are significantly as R² = 0.2441 and R² = 0.7359. Respectively, results of spatial
model have shown a range of sedimentation problems from upstream to the downstream
areas and revealing the downstream to be most critical compared to middle stream and
upstream which is as a result of river processes, land use, erosion processes and human
activities. Lastly, this study developed a structure model design for sedimentation
problems management in Binanga Aron River Basin based on the secondary and
primary data of hydraulic designs characteristic. These sedimentation problems due to
unsustainable land use changes, cliff erosion problems and active fish farming and
agricultural activities. This study suggests the structure hydraulic model design based
on GIS spatial model for sedimentation management. The implementation of
recommendations should be carried more specific for each settlement of sedimentation
problems in Binanga Aron River Basin to avoid and minimize various other problems
that will occur from the proposed solution.
