Bernward Holting, Wilhelm G. Coldewey - Hydrogeology
Springer, 2018
pdf, 368 pages, english
ISBN 978-3-662-56373-1
ISBN 978-3-662-56375-5 (eBook)
This hydrogeology book is the English translation of the German textbook "Hydrogeologie” by Hölting and Coldewey. Published since 1980, this book is in its eighth edition. Its great success is attributed to the concept of the book. It was important for the authors to write a text that is generally easy to understand, both for experts and for persons who do not work in this special field. Consistent use of the internationally accepted SI units as well as the formula symbols in the text also contribute to the comprehensibility. All technical terms and their definitions match the various standards and are used consistently. Moreover, the original literature citations were completely revised in order to avoid misunderstandings and errors due to secondary sources. All of these points improve the readability and facilitate the understanding of the relatively complex concepts of general and applied hydrogeology.
Because this textbook is translated from the German edition, many of the hydrogeological examples depict the Central European region. Even though they have general relevance, knowledge of the local situation is not required. Furthermore, the book cites laws and regulations of the Federal Republic of Germany and the European Union (EU), whose meaning and handling are certainly also interesting for readers from other countries.
May this book promote understanding of the complex material of hydrogeology as well as the correlations between the fields of geology, hydrochemistry, geohydraulics and engineering for a wide international public and contribute to solving global problems with groundwater development, exploitation, and protection. |

Practical Channel Hydraulics: Roughness, Conveyance and Afflux
2nd Edition
CRC Press, 2018
pdf, 634 pages, english
ISBN: 978-1-138-06858-2 (Hbk)
ISBN: 978-1-315-15777-1 (eBook)
 Practical Channel Hydraulics is a technical guide for estimating flood water levels in rivers using the innovative software known as the Conveyance and Afflux Estimation System (CES-AES). The stand alone software is freely available at HR Wallingford’s website www.river-conveyance.net. The conveyance engine has also been embedded within industry standard river modelling software such as InfoWorks RS and Flood Modeller Pro. This 2nd Edition has been greatly expanded through the addition of Chapters 6-8, which now supply the background to the Shiono and Knight Method (SKM), upon which the CES-AES is largely based.
With the need to estimate river levels more accurately, computational methods are now frequently embedded in flood risk management procedures, as for example in ISO 18320 (‘Determination of the stage-discharge relationship’), in which both the SKM and CES feature. The CES-AES incorporates five main components: A Roughness Adviser, A Conveyance Generator, an Uncertainty Estimator, a Backwater Module and an Afflux Estimator. The SKM provides an alternative approach, solving the governing equation analytically or numerically using Excel, or with the short FORTRAN program provided.
Special attention is paid to calculating the distributions of boundary shear stress distributions in channels of different shape, and to appropriate formulations for resistance and drag forces, including those on trees in floodplains. Worked examples are given for flows in a wide range of channel types (size, shape, cover, sinuosity), ranging from small scale laboratory flumes (Q = 2.0 1s-1) to European rivers (~2,000 m3s-1), and large-scale world rivers (> 23,000 m3s-1), a ~ 107 range in discharge. Sites from rivers in the UK, France, China, New Zealand and Ecuador are considered.
Topics are introduced initially at a simplified level, and get progressively more complex in later chapters. This book is intended for post graduate level students and practising engineers or hydrologists engaged in flood risk management, as well as those who may simply just wish to learn more about modelling flows in rivers. |

Rarlab WinRAR v5.60 bra+chi+eng+fra+ger+rus+por x32+x64
Архиватор RAR является самой распространенной программой после операционной системы и браузера, ведь большинство программ и в Интернете, и у пользователей хранятся в сжатом виде в архивах.
WinRAR – мощная утилита для создания и управления архивами, содержащая целый спектр дополнительных полезных функций. Программа WinRAR ежедневно используется миллионами людей во всем мире для экономии места на ПК и быстрой передачи файлов.
WinRAR больше не поддерживает Windows 98, Windows Me, Windows NT.
What's new in the latest version:
Version 5.60
1. We updated WinRAR graphics.
We are grateful to http://weirdsgn.com and http://icondesignlab.com
designers participated in this endeavor and proud to announce that
WinRAR uses the new icon set prepared by Aditya Nugraha Putra
from http://weirdsgn.com.
Previous WinRAR icons are available as interface theme here:
https://rarlab.com/themes/WinRAR_Classic_48x36.theme.rar
2. "Repair" command efficiency is improved for recovery record protected
RAR5 archives. Now it can detect deletions and insertions of unlimited
size also as shuffled data including data taken from several recovery
record protected archives and merged into a single file in arbitrary
order.
3. "Turn PC off when done" archiving option is changed to "When done"
drop down list, so you can turn off, hibernate or sleep your PC
after completing archiving.
4. Use -ioff or -ioff1 command line switch to turn PC off,
-ioff2 to hibernate and -ioff3 to sleep your PC after completing
an operation.
5. If encoding of comment file specified in -z<file> switch is not
defined with -sc switch, RAR attempts to detect UTF-8, UTF-16LE
and UTF-16BE encodings based on the byte order mask and data
validity tests.
6. WinRAR attempts to detect ANSI, OEM and UTF-8 encodings of
ZIP archive comments automatically.
7. "Internal viewer/Use DOS encoding" option in "Settings/Viewer"
is replaced with "Internal viewer/Autodetect encoding".
If "Autodetect encoding" is enabled, the internal viewer attempts
to detect ANSI (Windows), OEM (DOS), UTF-8 and UTF-16 encodings.
8. Normally Windows Explorer context menu contains only extraction
commands if single archive has been right clicked. You can override
this by specifying one or more space separated masks in "Always display
archiving items for" option in Settings/Integration/Context menu items",
so archiving commands are always displayed for these file types
even if file was recognized as archive. If you wish both archiving
and extraction commands present for all archives, place "*" here.
9. SFX module "SetupCode" command accepts an optional integer parameter
allowing to control mapping of setup program and SFX own error codes.
It is also accessible as "Exit code adjustment" option
in "Advanced SFX options/Setup" dialog.
10. New "Show more information" WinRAR command line -im switch.
It can be used with "t" command to issue a message also in case of
successful archive test result. Without this switch "t" command
completes silently if no errors are found.
This switch is applicable only to WinRAR.exe and ignored by console
RAR.exe.
11. If a wrong password is entered when unpacking an encrypted file
in ZIP archive, WinRAR proposes to enter a valid password
for same file again instead of aborting extraction.
12. If a wrong password is entered when opening or unpacking RAR archive
with encrypted file names, WinRAR proposes to enter a valid password
again instead of aborting the operation. Previous versions already
did so for RAR archives with encrypted file data, but aborted
for archives with file name encryption.
13. WinRAR recognizes GZIP files with arbitrary data preceding
an actual GZIP archive, such as .scexe firmware files.
14. @filelist parameter can be specified in "Files to add" field of
archiving dialog. In this case WinRAR will attempt the list of archiving
files from 'filelist' file, which should be the plain text, one file
name per line.
15. Info dialog:
a) compression ratio graph is updated;
b) "Names and data" is displayed in "Encryption" field for
archives with encrypted file names.
16. Full archive name is displayed if mouse pointer is placed over
an archive name in the operation progress window. It can be useful
if archive name is lengthy and does not fit to available window space.
17. If -ts1 switch is used with -u or -f, file time comparison is performed
with 1 second precision. Previosuly in such case we could wrongly treat
an adding file as newer than archived just because we compared the high
precision adding file time against the low precision archived file time.
18. "Update" and "Fresh" commands ('u' and 'f' in the command line mode)
quit immediately if no files are to be updated. Previously they created
a temporary archive before quitting when updating archives with recovery
record or quick open information.
19. Prompt is issued after creating 500 volumes from WinRAR GUI shell,
so user can continue or quit further archiving. It is done to prevent
creating many thousands of volumes in case of wrongly entered
volume size.
20. WinRAR uses megabytes instead of bytes as default units for volume size
field in the archiving dialog.
21. "Repair" command issues "Recovery record is corrupt" message
after repairing RAR5 archive containing a broken recovery record.
Previously such message was issued only by "Test" command
and "Repair" handled most of recovery record damages silently.
22. Bugs fixed:
a) fixed potential security issues when processing corrupt
RAR archives;
b) non-English characters in TAR files with PAX extended headers
were not displayed correctly;
c) "rar x arcname.rar .." command unpacked files to current folder
instead of its parent;
d) pasting files from Windows Explorer to archive opened in WinRAR
blocked further copy and paste operations in Explorer until
archiving was finished;
e) SFX module issued "The specified password is incorrect" message
infinitely not prompting for correct password once a wrong password
was entered;
f) folders time was always set when extracting ZIP archives even if
"File time" options in the extraction dialog were turned off;
g) if "Delete archive: Always" was selected when extracting
and user pressed "Cancel" in the file overwrite or password prompt,
an archive could be deleted even after cancelling extraction
for .zip and .7z formats. |
