Despite the impact of temperature and precipitation patterns on river flow is an emerging issue in hydrology, few studies have been concentrated on the correlation between the hydrological components and climate indices. This study mainly focuses on the projected extreme climate indices and the effects of climate change projections on the hydrological process in the Bago River Basin, Myanmar. It has been noted that the mean monthly maximum temperature values are expected to rise throughout the entire basin under the RCP 4.5 scenario. On the other hand, the annual total precipitation index is anticipated to increase. The findings imply that the groundwater and surface flow will eventually expand as a result of the effects of extreme precipitation indices. Subsequently, there will be a decrease in the lateral flow. Furthermore, it is observed that the effect of temperature indices will cause a significant impact on evapotranspiration. This paper highlights that the crucial part of the extreme climate indices that influence the regional hydrological processes of the Bago River Basin in the upcoming decades.

In Indonesia, the most serious issue is garbage. As a result, with a total waste of 1.92 million tons, it has been named the number two contributor of plastic waste to the sea. Garbage disposal in the river can be harmful to downstream residents, especially fishermen. Because of the accumulation of garbage in the riverbed, the river becomes very shallow, causing the water to overflow when it rains, which can cause flooding. The goal of this final project is to design superstructure and substructure dimensions and reinforcement. To reduce waste entering the sea, trash traps are built in estuaries by filtering surface waste. The Floating Trash Trap model, as well as its dimensions and sizes, is the scheme and design of the planned trash trap. The focus of the superstructure is on the control of steel profiles and bolt anchors, while the focus of the substructure is on the foundation. SAP 2000 software was used for structural design analysis. The superstructure design results were safe for all existing loading combinations.
