Groundwater Pollution: Theory, Methodology, Modelling, and Practical Rules
Author: Jean J. Fried | Size: 17.43 MB | Format:PDF | Quality:Original preprint | Publisher: Elsevier Science Ltd | Year: November 1975 | pages: 330 | ISBN: 0444413162, ISBN-13: 978-0444413161
Pollution has become the ever-increasing monster that threatens our civilization (what is left of it, at least), the Moloch that will eat us. This is what the information media say, and perhaps they are right; now again perhaps they are wrong, or at least too pessimistic. We feel that the real danger is not pollution but the ignorance of pollution problems. This book built around the example of groundwater pollution, is an attempt to rationalize and to quantify the problem and to show that the danger of pollution should not be despised, of course, but conversely, it should not be exaggerated.

This British Standard gives guidance on durability, required and predicted service life and design life of buildings and their components and/or parts. It applies primarily to new buildings and their components and/or parts rather than to alterations and repairs. It also gives guidance on presenting information on the service and design life of buildings and their components and/or parts when a detailed brief is being developed.
This British Standard applies to civil engineering projects involving buildings, but only partially to other civil engineering projects such as roads, bridges and dams.
This British Standard does not deal with many aspects of obsolescence, i.e. when buildings or parts of buildings are replaced or altered either to suit different needs and changing conditions including change of use, mandatory requirements or when new products offer better performance without a corresponding increase in cost. It should also be borne in mind that a decision to replace or alter obsolete buildings or their parts may be influenced
by a reassessment of their predicted service lives.
NOTE 1 The titles of the publications referred to in this standard are listed on the inside back cover.
NOTE 2 The numbers in square brackets in the text of this standard refer to the numbered references in Appendix D.

Dictionary of Waste & Water Management
Author: Paul G. Smith, John S. Scott | Size: 4.9 MB | Format:PDF | Publisher: BUTTERWORTH HEINEMANN | Year: 2002 | pages: 448 | ISBN: 0750646381
Water and waste management covers the design, building and operation of plants for water treatment and supply, sewerage, wastewater treatment and disposal, and solid waste treatment and disposal. Since the last edition in 2002 there has been an increasing importance on the issues reflecting climate change. This is particularly important when the result of this change must be `managed? and `controlled? to maintain an amenity such as water supply. This new edition includes many new entries on the topics of stormwater management and flood management, as well as the new EU Directives that cover this field. With over 7000 terms, this dictionary encompasses the most recent terminology on water and waste management. It is a handy reference for consultants, contractors and professional engineers as well as academics and students who need a quick definition to technical terms.
Audience:
Civil, environmental and chemical engineering professionals. Environmental biologists, environmental chemists and environmental managers.

Updated edition of a best-selling title – Author brings 25 years experience to the work – Addresses the key issues of economy and environment Marine pipelines for the transportation of oil and gas have become a safe and reliable way to exploit the valuable resources below the world?s seas and oceans. The design of these pipelines is a relatively new technology and continues to evolve in its quest to reduce costs and minimise the effect on the environment. With over 25years experience, Professor Yong Bai has been able to assimilate the essence of the applied mechanics aspects of offshore pipeline system design in a form of value to students and designers alike. It represents an excellent source of up to date practices and knowledge to help equip those who wish to be part of the exciting future of this industry.
Audience:
Structural and civil engineers, students and researchers.
Part I: Mechanical design
Part II: Pipeline Design

This is something I have known since my hostel days at IIT Delhi in the seventies. I have wondered many times, and this could be a research topic.
If you take two eggs one in each hand, and then hit them one against the other, only one will break. That is how I break eggs, and for the last one left I have to hit it against the plate or fork ot whatever. When you hit the two eggs together, I never had to worry about small shell fragments. Try it yourself. Never once in the last 30 plus years have I broken them simultaneously.
Let us say Egg 1 (E1) and E2
You break E2. Then hit E1 and E3. Either E1 or E3 will break, and so forth.
Try it. Never fails. I have done it thousands of time.
My academic challenge to the forum - what is the mathematics/physics/material science behind this ? Please free to share with non CEA members. Someone can probably get a PhD for this, I hope.
i guess i dont need to explain what is the book about

General
HEC-6 (HEC, 1991) is a one-dimensional movable boundary open channel flow and sediment
model designed to simulate changes in river profiles due to scour and deposition over fairly long time
periods (typically years, although applications to single flood events are possible). The continuous flow
record is broken into a sequence of steady flows of variable discharge and duration. For each flow a
water surface profile is calculated thereby providing energy slope, velocity, depth, etc. at each cross
section. Potential sediment transport rates are then computed at each section. These rates, combined
with the duration of the flow allow for a volumetric accounting of sediment for each reach. The amount of
scour or deposition at each section is then computed and the cross section shape adjusted accordingly.
The computations then proceed to the next flow in the sequence and the cycle is repeated beginning with
the updated geometry. The sediment calculations are performed by grain size fraction thereby allowing for
the simulation of hydraulic sorting and armoring. Features of the model include: capability to analyze
networks of streams, automatic channel dredging, various levee and encroachment options, and several
options for computation of sediment transport rates.
Experience has shown that successful application of movable boundary models may require
substantial effort to reproduce field observations, i.e. calibration. This document complements the HEC-6
User's Manual (HEC, 1991) and provides guidelines for calibration and application. The general topic of
application and calibration of numerical river models is thoroughly covered in Cunge, et al. (1980).
This document provides guidance on the engineering aspects of applying HEC-6; it is, therefore, a
supplement to the HEC-6 User's Manual. Originally published in 1981, this edition contains substantial
new material based on program enhancements and applications experience gained since then.
This document was prepared by D. Michael Gee, Training Division, HEC. William A. (Tony)
Thomas, Hydraulics Laboratory, WES, provided most of the concepts and material included herein. Vern
Bonner was Chief, Training Division and Darryl W. Davis, Director, HEC, during preparation of this report.

I am not an engineer but an architect. Our profession has been hit by the recession pretty hard. A lot of us were fired, and the generally the situation is at the average level pretty harsh.
I was wondering if we can share some experiences in these times, about the recession related to engineers.
