Flow and sediment matrix for the formation of midland point bars in sand bed channel / Duratul Ain Tholibon

A large number of studies, both theoretical and experimental have been devoted to understanding the physical mechanisms underlying the bar formation. Numerous data on bar formation have been accumulated yet the methods to predict bar geometry, especially bar height are still insufficient. This research aims to investigate the parameters that promote bar formation in term of bar height. Investigation was carried out on an erodible sand bed channel using a large-scale physical river model. Study have included various hydraulic and sediment characteristics with steady flow rates and sediment supply. There are four matrices of flow rate and channel width with other variables, namely grains size and bed slope which were kept constant. A relationship between dimensionless bar heights with the respective independent parameters has been established. Bar profile development was generated using Surfer, of which 3D elevation plots are given. Analysis has included the discussion on a significant difference of planform view for each experimental condition, trends in volume change along the channel, widening ratio and centreline bed elevation profile along the longitudinal distance. Both experimental and historical data were used to develop the empirical model. Model development involved selection of parameters through review of established models, dimensional analysis to check on the homogeneity of the model and statistical analysis. Derived empirical model has been validated using a different set of data from previous studies

An Investigation on the Preference Approach in Experiencing Open and Distance Learning Methods

Open and distance learning (ODL) has become an alternative in teaching and learning (T&L) while the COVID-19 pandemic crisis struck the world globally in December 2019. However, the preferred tool and platform to be chosen in the transition period among students remain uncertain. The purpose of this study was to assess and investigate the effect of T&L preference techniques and technologies chosen by employing ODL in universities during the pandemic. This research adopted a descriptive approach and a quantitative survey was used to collect the necessary data. The questionnaire consisted of 14 questions and was separated into two parts: demographic information and undergraduate students' preference towards online class technology during the COVID-19 pandemic. Four themes and 16 sub-themes were identified in the set of questions in the survey. The results of the analysis revealed that ODL is the preferred method with WhatsApp social media platform as the medium for communication between educators and learners. Educators might consider devoting additional attention to improving teaching and learning practices in open and distance learning in choosing the right approaches and platform to be used through online and offline classes
