1.0 INTRODUCTION
The correlation of soil properties with its index properties have been used by engineers to estimate the engineering properties of a soil if the index properties are known. This is especially important where there is inadequate information from the site and laboratory investigation results or where results need to be validated with the existing literature values in order to determine the appropriate soil design parameters.
Many renowned researchers such as Carrier and Beckman (1984), Carter and Bentley (1991), Henkel (1959), Houlsby and Whithers (1988), Skempton (1957), and Wroth and Wood (1976) have developed correlations that relate engineering properties of soil with its index properties. Since these correlations were made there had been advances in the field and laboratory testing for the determination of both index and engineering properties of soil. This study attempts to systematically review and synthesise the existing correlations between the permeability, shear strength, and compressibility of soil with Atterberg limits and make recommendations for modifications where necessary based on the current geotechnical engineering practice and development of soil testing. Since the method of performing both the index tests and engineering parameter tests has a direct influence on the correlation of the index properties with the engineering properties.
This chapter covers the review of related literature, foreign and local, published articles including journals and other periodicals such as being available and relevant to the subject under investigation. In this wise therefore, contemporary materials, opinions and presentations shall be decisively employed and reviewed. A total of 150 published articles...

Darcy’s law provides an accurate description of the flow of ground water in almost all hydrogeological environments. Henri Darcy established empirically that the flux of water through a permeable formation is proportional to the distance between top and bottom of the soil column.
The aim of this paper is to explore and critically analysing two research articles. The critical analysis will explain the importance of the study, evaluate design and research method used in those articles. To identify any gaps it will provide the literature review in those researches and possibility for the new study. The project plan, for the possible research will be developed on a potential gaps and the essay will finish with the conclusion.
The Methodology used to gather information for this paper was found through various sources. The sources used are all verifiable and established informational resources including (but not limited to) the following; course textbooks, books, journals, and online databases.
Nitrogen and Irrigation on Coastal Plains Soils. So why is it important to look at nitrogen in soils? First of all, it is a key element in organic molecules, so it is key to plant growth (Singer and Munns). Nitrogen is useful to plants in the form of nitrate because plants can take in nitrate and form organic molecules (Singer and Munns, 1993).

The authors of this article have outlined the purpose, aims, and objectives of the study. It also provides the methods used which is quantitative approach to collect the data, the results, conclusion of the study. It is important that the author should present the essential components of the study in the abstract because the abstract may be the only section that is read by readers to decide if the study is useful or not or to continue reading (Coughlan, Cronin, and Ryan, 2007; Ingham-Broomfield, 2008 p.104; Stockhausen and Conrick, 2002; Nieswiadomy, 2008 p.380).

In conclusion, while selecting articles to use for this research, these particular articles proved to be very useful. They both met the criterion for the purpose of research information, as well as having current information on the topics.
... although we may never be able to understand exactly what soil failures can occur when a natural disasters take place, as time goes on and testing instruments and materials advance we will hopefully have a better understanding of what we can do to avoid soil failures and come up with a better and more sufficient method of improving the soils structure and strength permanently. While researching the information for this report I feel I have a much better understanding for construction geo-technics and foundations especially regarding the deformation, liquefaction and pile information related to this specific event. I hope to carry the information I have learned from this event into the construction field and apply them towards an authentic project that’s taking place and know that the information, regarding soils, I have given input on will be precise and accurate.
Geotechnical Engineering covers the engineering properties of soils, the fundamentals of soil mechanics, and the application of geotechnical data and fundamentals to the design of foundation elements, earth-retaining structures, excavations, earth embankments and highway pavements.
