Located on the banks of the Buriganga River, Dhaka is the capital of Bangladesh . Along with its
metropolitan Dhaka has a population of over 12 million. Day by day Dhaka is badly affected by huge traffic
jam. Due to traffic jam a substantial portion of working hours have to be left on streets which create adverse
impact on economy. Traffic jam has also many other negative impacts on economy, environment and human life.
For this purpose this paper has given its attention on the impacts of traffic jam in Dhaka city.

We apply the recently derived constraintless Clairaut-type formalism (by S. Duplij) to the Cho-Duan-Ge decom- position in SU(2) QCD. We find nontrivial corrections to the physical equations of motion and that the contribution of the topological degrees of freedom is qualitatively different from that found by treating the monopole potential as though it were dynamic. We also find alterations to the field commutation relations that undermine the particle interpretation in the presence of the chromomonopole condensate.

Numerical modeling in support of the characterization and remediation of impacted sediments can be a challenging task, particularly in environments where multiple physical processes influence sediment fate and transport. The interaction of various controls is particularly complex in estuarine settings, where riverine input, water levels, waves, and other coastal processes combine to create a seasonally dynamic environment. Modeling of such environments requires a comprehensive and integrated approach such that the effects of each process can be assessed individually, as these processes can be allowed to interact to reproduce the natural environment as faithfully as possible
Approach and Activities
This contribution describes the development and calibration of an integrated Delft3D numerical model that includes flow, sediment transport, wave processes, and vegetation. The model boundary conditions are based on data collected during a comprehensive field program. Field data were also used to calibrate various model input parameters (such as bed and vegetation roughness). The model was used to understand erosion and deposition during both low and high flow regimes, and thus to aid in understanding important controls on sedimentary dynamics during these predominant regimes.
Results and Lessons Learned
The integrated numerical model predictions capture important sedimentation, erosion, velocity, and water level patterns. Model predictions indicate that during periods of low riverine input, velocity patterns and sediment transport associated with periodic water level changes dominate. During riverine flood conditions flow and sedimentation patterns are controlled by the river itself. Integrated modeling of this setting, including calibration to field data provides a valuable tool for assessment of future conditions, and thus for remediating impacted sediments.

This project essentially looked at the stability of a deepened approach channel and examined the impact of the dredging and disposal for the scheme in support of a public planning hearing. The modelling used coupled MIKE 21 FM HD-SW-ST models as well as well as MIKE 21 and MIKE 3 FM HD and MT models.

The Groundwater and Storage interactions project arose out of a meeting on the shoulder of the Greenhouse Gas Technologies Conference in Amsterdam in 2010. It was decided to concentrate initially on the Australian Flagships projects. On 3 May 2011 Australian researchers and government agencies met and presented their work to date.

15. Summary
• Generally, model results and ferry-based observations for
salinity values exhibit similar ranges.
• Extended and deepened river channel improves surface
currents by generating stronger cross-strait surface flows.
• Reducing vertical eddy viscosity and diffusivity is important
to produce weaker along-strait flows.
• Lower diffusivity reduces upper layer salinity values, which
increases the accuracy of model results compared to observed
ferry salinity.
• A longer river with lower viscosity and diffusivity minimizes
the overall discrepancies for modeled surface flows.
