The PDF version was downloaded more than times in the first week. And, as surface water — the water in river and lakes — becomes increasingly scarce, people are using groundwater for drinking water and irrigation. So people in areas short of water tend to pump fossil groundwater, drawing down water tables significantly, with very little regulation.


Geotechnical Practice for Waste Disposal pp Cite as. The basic theory and concepts of hydrogeology will be discussed in this chapter. Sections 4. Section 4. Geologic characteristics such as permeability, porosity, anisotropy, and homogeneity, are functions not only of the type of rock or soil material, but also of the depositional environment, diagenesis, and tectonic processes such as folding and faulting that may have occurred after deposition. This information is needed to build a geologic framework in which hydrogeologic principles may be applied before ground-water flow and contaminant transport can be evaluated.

The Groundwater Project, a non-profit organization, registered in Canada, is committed to contribute to advancement in education by creating and making available online free high-quality groundwater educational material for all. The Groundwater Project is led by Dr. John Cherry, recipient of the Stockholm Water Prize, and managed by a member international Steering Committee and a larger and globally diverse Advisory Committee. To advance the state of the science worldwide, the authors then agreed to provide free downloads of the original text and translations through the Hydrogeologists Without Borders website. This laudable initiative provided the inspiration for the much larger Groundwater Project aimed at updating and largely expanding the coverage of the original book. As of today, more than 20 institutions are partnering with us and many others are on their way.

Getting ‘Groundwater’ into cyberspace: A seminal textbook goes online

The Mazar-i-Sharif city is part of the Balkh province, north of Afghanistan, and its groundwater resources are developed for water supply and irrigation purposes. The main lithological units consist chiefly of evaporite, conglomerate, sandstone, siltstone, and loess. In order to evaluate the quality of groundwater in the study area, 28 samples were collected and analyzed for various ions. Chemical indices like sodium adsorption ratio, the percentage of sodium, residual sodium carbonate and permeability index were calculated. Based on the analytical results, groundwater in the area is generally very hard, brackish, high to very high saline, and alkaline in nature.

This text book is almost as old as I am and important parts of modern hydrogeology are rusty or non-existent like hydroecology amongst other topics but it is still lucidly written and useful. I routinely send students to read chapters so I am happy that it is now available free. I look forward to Groundwater2. Your email address will not be published. By Tom Gleeson. I am a hydrogeologist at University of Victoria, Canada who is interested in groundwater sustainability, mega-scale groundwater systems, groundwater recharge and discharge and fluid flow around geologic structures.

Please see digital version for latest info. More reading: at the course website in the "virtual reader" see syllabus below with links. Notes about reading and other assignments: Please complete reading prior to class discussion, ask questions in class and lab, visit during office hours. Please read assigned materials more carefully a second time after topic is discussed in detail or used in lab. Labs and problem sets are normally due one week after being handed out, but the start of the associated class or lab.

Она смутно помнила, что для создания этого центра из земли пришлось извлечь 250 метрических тонн породы. Командный центр главного банка данных располагался на глубине шестидесяти с лишним метров от земной поверхности, что обеспечивало его неуязвимость даже в случае падения вакуумной или водородной бомбы. На высокой рабочей платформе-подиуме в центре комнаты возвышался Джабба, как король, отдающий распоряжения своим подданным. На экране за его спиной светилось сообщение, уже хорошо знакомое Сьюзан. Текст, набранный крупным шрифтом, точно на афише, зловеще взывал прямо над его головой: ТЕПЕРЬ ВАС МОЖЕТ СПАСТИ ТОЛЬКО ПРАВДА ВВЕДИТЕ КЛЮЧ_____ Словно в кошмарном сне Сьюзан шла вслед за Фонтейном к подиуму.

Вскоре слава о фугуся-кисай, гениальном калеке, облетела Токио. Со временем Танкадо прочитал о Пёрл-Харборе и военных преступлениях японцев. Ненависть к Америке постепенно стихала. Он стал истовым буддистом и забыл детские клятвы о мести; умение прощать было единственным путем, ведущим к просветлению. К двадцати годам Энсей Танкадо стал своего рода культовой фигурой, представителем программистского андеграунда.

 - И он положил конверт на стойку. Консьерж взглянул на конверт и что-то грустно пробормотал себе под нос. Еще один любитель молоденьких девочек, - подумал. - Ну. Сеньор?.

В его голосе слышалось скорее недоумение, чем шок: - Что ты имеешь в виду. - Хейл… - прошептала Сьюзан.  - Он и есть Северная Дакота. Снова последовало молчание: Стратмор размышлял о том, что она сказала.

Сьюзан бросила быстрый взгляд на Хейла, но тот был всецело поглощен своим компьютером. Затаив дыхание, Сьюзан дважды щелкнула по конверту. - Северная Дакота, - прошептала она еле слышно.

Стратмор опустился на колени и повернул тяжелый винтовой замок. Теперь крышку не поднять изнутри. Подсобка компьютера надежно закрыта. Ни он, ни Сьюзан не услышали тихих шагов в направлении Третьего узла.
