Every year, millions of scrap tires are either discarded in huge piles across the landscape or dumped in landfills in large volumes all over the world. These tire piles cause environmental pollution while posing fire and health hazards. Being volumetr . . .

This paper presents the results of a study, whose aim was to determine the undrained shear strength at different over-consolidation ratios, which is a very important parameter to evaluate the stability of natural and man-made slopes in soft clay. The . . .

Global warming is a big concern these days all over the world including in the USA. It has said to trigger landslides all over the world every year due to the global warming. Landslides can damage the structures and block roads and rivers that require . . .

Based on previous studies, ground reinforcement methods such as stone columns, jet grouting, dynamic compaction, soil cement mixing, etc. are commonly used against potential liquefaction, settlement and to improve the bearing capacity of soil. However . . .

Infiltration is an important aspect to the hydrologic cycle as it allows for groundwater recharge. In California especially, groundwater is used for agriculture, industrial usage, and as drinking water. This Thesis presents an analytical model for tim . . .

Landslides, which have been existing around the world, are considered as environmental hazards. The number of landslide hazard is increasing every year. Although there are different causes of landslides, two major causes are rainfall and earthquake. R . . .

Large amounts of waste materials such as waste tires, rubbers, etc. are discarded into our surrounding environment. Thus, they are a major cause of contamination and pollution, which, as a result, could eventually lead to many problems including healt . . .

Soil is unlike other construction materials such as steel and concrete for which humans can control their properties. Therefore, it is important to investigate and test soil in order to predict its response to the construction loading. The coefficient . . .

The aim of this thesis is to provide a tool for contractors to select optimal equipment for projects, which will increase cost efficiency and reduce environmental impacts. The target geographic area for this research is the state of California, and th . . .

This study focuses on the analysis of rainwater runoff from an extensive green roof system. Over time, space that was formally available for rainwater to properly infiltrate to the ground is being taken up by impervious built surfaces. Green roof tech . . .
