Petroleum geoscience comprises those geoscientific disciplines which are of greatest significance for the exploration and recovery of oil and gas. These include petroleum geology, of which sedimentary geology is the main foundation along with the contextual and modifying principles of regional, tectonic and structural geology. Additionally, biostratigraphy and micropalaeontology, organic geochemistry, and geophysical exploration and production techniques are all important tools for petroleum geoscientists in the 21st century. This comprehensive textbook present an overview of petroleum geoscience for geologists destined for the petroleum industry. It should also be useful for students interested in environmental geology, engineering geology and other aspects of sedimentary geology.

Most large urban centres lie in coastal regions, which are home to about 25 per cent of the world's population. The current coastal urban population of 200 million is projected to almost double in the next 20 to 30 years. This expanding human presence has dramatically changed the coastal natural environment. To meet the growing demand for more housing and other land uses, land has been reclaimed from the sea in coastal areas in many countries, including China, Britain, Korea, Japan, Malaysia, Saudi Arabia, Italy, the Netherlands, and the United States. Coastal areas are often the ultimate discharge zones of regional ground water flow systems. The direct impact of land reclamation on coastal engineering, environment and marine ecology is well recognised and widely studied.However, it has not been well recognised that reclamation may change the regional groundwater regime, including groundwater level, interface between seawater and fresh groundwater, and submarine groundwater discharge to the coast. This book first reviews the state of the art of the recent studies on the impact of coastal land reclamation on ground water level and the seawater interface. Steady-state analytical solutions based on Dupuit and Ghyben-Herzberg assumptions have been derived to describe the modification of water level and movement of the interface between fresh groundwater and saltwater in coastal hillside or island situations. These solutions show that land reclamation increases water level in the original aquifer and pushes the saltwater interface to move towards the sea. In the island situation, the water divide moves towards the reclaimed side, and ground water discharge to the sea on both sides of the island increases.After reclamation, the water resource is increased because both recharge and the size of aquifer are increased. This book then derives new analytical solutions to estimate groundwater travel time before and after reclamation. Hypothetical examples are used to examine the changes of groundwater travel time in response to land reclamation. After reclamation, groundwater flow in the original aquifer tends to be slower and the travel time of the groundwater from any position in the original aquifer to the sea becomes longer for the situation of coastal hillside. For the situation of an island, the water will flow faster on the unreclaimed side, but more slowly on the reclaimed side. The impact of reclamation on groundwater travel time on the reclaimed side is much more significant than that on the unreclaimed side. The degree of the modifications of the groundwater travel time mainly depends on the scale of land reclamation and the hydraulic conductivity of the fill materials.

This monograph sets forth a unified approach and principles for modeling hydrologic processes distributed in space and time using geographic information systems (GIS). The focus of this Second Edition is on the principles of how to implement a distributed model using geospatial data to simulate hydrologic processes. Once we embark on fully distributed representations of hydrologic processes, conservation laws form the basis for modeling, and spatial data management becomes necessary. A physics-based approach involves the laws that govern the complexities of all the paths that water travels, from precipitation falling over a river basin to the flow in the river. Worldwide geospatial data has become readily available in GIS format. A modeling approach that can utilize this data for hydrology offers many possibilities. GIS data formats, spatial interpolation, and resolution have important effects on hydrologic simulation of the major hydrologic components of a watershed. Examples are provided that illustrate how to represent a watershed with spatially distributed data along with the many pitfalls inherent in such an undertaking. Since the First Edition, software development and applications have created a richer set of examples, and a deeper understanding of how to perform distributed hydrologic analysis and prediction. This Second Edition is oriented towards a commercially available distributed model called Vflo™.

There are a surprisingly small number of encyclopedias covering environmental science and environmental issues. The expanded and updated edition of Gale's Environmental Encyclopedia does little to improve on the quality of such offerings.
Entries range from 100 to more than 2,000 words. Some are complemented by black-and-white photographs and diagrams. Each entry is signed, and topical coverage includes a broad range of environmental perspectives, including scientific, political, and social issues. Most of the entries are followed by a brief bibliography. However, these bibliographies are inconsistent, some pointing to a large number of standard and useful sources, others leading the user to an odd selection of works that do not represent comprehensive or core treatments of the issue at hand.

I still have one semester remaining to finish my second year studies. What I’m wondering about is what to do over the summer, the reason I choose to learn some software’s is because of the intern I will have over the next year summer in Dubai. This while enhance me lot better to do any task required, but the face lies in selecting the correct program.
Courses that I’ve successfully completed are:
Structural Analysis 1
Surveying 1, 2
Architectural Panning and Construction
Civil Engineering Drawing
Actually, there are more major courses such as traffic and transportation, geology and others but I would like to focus on the structural side.
Programs that I was thinking of completing over the remaining three consecutive summers are:
Summer 1: AutoCad 2D and Staad Pro
Summer 2: Revit Structural Modelling(3D)
Summer 3: Primavera Project Planner.
The Problem is that Can I start taking Revit structural Modelling this summer after just finishing Structural analysis 1.
Besides what do you prefer me choosing from Revit structural modeling , Bentley structure or AutoCAD Civil 3D and why.
