 Civil Engineering Research Journal- Juniper Publishers   Abstract This study explores the geologic peculiarities of the Niger Delta region, which creates a propensity for the significantly high cost of highway development. The heterogeneous geologic configuration of the area, in terms of its landscape, geomorphology and hydrology are descriptively and techno-economically analysed, based on available local literature, supplemented by geotechnical field work data. The study discusses and analyses the construction cost implications of the inherent geo-variability of the terrain, and the financial implications as it relates to the practicalities of carrying out road construction in the Niger Delta. The analysis outlines the cost considerations associated with highway pavement and drainage construction in view of the hydro-geomorphological setting of the Niger Delta. The analysis reiterates the predominance of fined grained subgrade soils, which will require remedial re-engineerin...

 Civil Engineering Research Journal- Juniper Publishers   Abstract Installation and monitoring of instrumentation is one of the practical methods for controlling safety and stability of earth dams. Piezometers existing in dam body and dam abutments are one of the various types of precision instruments used in dams, which indicate the height of water level in different parts of the dam. In order to evaluate the performance of piezometers of Shah Qasim Dam in Kohgiluyeh and Boyerahmad province (in south east of Iran), we compare water level changes in piezometer and water level changes in the dam lake over time. In this paper, the above-mentioned dam is modelled using the SEEP/W software, then after imposing boundary conditions, water levels are computed at various points. For more accurate comparison, water level changes are plotted in transverse and longitudinal piezometers over time. The results of analysis indicate significant increase of permeability in vicinity of some pie...

 Civil Engineering Research Journal- Juniper Publishers   Abstract Throughout the years of development in laboratory testing of concrete some need has been urged to measure the deformations on the specimens. As there are some methods for this purpose such as putting sensors on the specimens, the need for a new method was still existed. Old fashion methodologies utilize long cables for measuring deformations. On the other hand, digital image correlation (DIC) is a remote technique which can be applied without any physical interaction with the specimen. Being relatively a low-cost option and measuring the displacements in micro level of precision made it very desirable for the researchers over the years. Materials such as concrete can be assumed to heterogeneous as it consists of steel reinforcements, pozzolans, cement, water, and aggregates. Therefore, failures along the concrete specimens can vary from very simple to very complex. Considering these reasons, determining any fai...
