Finding Groundwater
Water Resources Engineering and Management - A Civil Engineering Course under the National Programme on Technology Enhanced Learning
Posted on 29 Sep, 2010 07:42 AMThis Civil Engineering Course under the National Programme on Technology Enhanced Learning (NPTEL) on the broad subject of Water Resources Engineering and Management is being carried out by Indian Institute of Technology’s and the Indian Institute of Science, Bangalore as a collaborative project supported by the Ministry of Human Resource Development (Government of India) to enhance the quality of engineering education in the country, by developing curriculum based video and web courses. In these web based lectures, the authors have developed the subject in detail and in stages in a student-friendly manner. The broad group of Water Resources Engineering is structured into modules on the topic by IIT Kharagpur as follows:
Aquifers: The hosts of groundwater – A presentation by ACWADAM
Posted on 25 Sep, 2010 08:44 AMThis presentation by ACWADAM on aquifers states that a systematic approach to groundwater studies is required to understand how water exists in each type of rock or sediment for which hydrogeological mapping of aquifers becomes significant in every watershed programme. The necessity of studying the scientific aspects of groundwater such as its properties and distribution below the earth’s surface is highlighted.
Processes that shape the earth: Part I – A presentation by ACWADAM
Posted on 24 Sep, 2010 07:04 PMThis presentation by ACWADAM on processes that shape the earth attempts to understand the irregularities of the surface of earth so as to consider the movement of groundwater. The earth’s surface is dotted with what is commonly perceived as high grounds or ‘hills’ and the low grounds or ‘valleys’. Hills and valleys result from movements in the earth and the long term processes of breaking-down the earth surface at some places and building it up at others, also called as diastrophism.
Groundwater modeling – A presentation by ACWADAM
Posted on 23 Sep, 2010 08:13 PMThis presentation by ACWADAM deals with groundwater modeling using the Water Evaluation and Planning System (WEAP) model. WEAP is a microcomputer tool for integrated water resources planning and operates on the basic principle of a water balance. WEAP is distinguished by its integrated approach to simulating water systems and by its policy orientation. It provides a comprehensive, flexible and user-friendly framework for policy analysis.
Earth sciences in watershed management – A presentation by ACWADAM
Posted on 23 Sep, 2010 08:04 AMThis presentation by ACWADAM on earth sciences in watershed management shows how the occurrence of water within a watershed is governed by the rock types occurring both at the surface and within the subsurface, their sequence and their structure. The presentation deals with the basic components involved in the mapping of a watershed –
- The type of rocks (lithology), and
- The structure (whether these are folded, faulted, fractured, jointed etc.,)
The structure of the sub-surface – A presentation by ACWADAM
Posted on 22 Sep, 2010 09:38 PMThis presentation by ACWADAM deals with the structure of the sub-surface. The lithology and structure of rocks together define the geometric framework for the movement of groundwater. To some extent, these factors also govern the movement of surface water too. In other words, the physical environment of rocks and rock material hosts water, and hence, controls its accumulation and flow in the watershed.
Importance of groundwater – A presentation by ACWADAM
Posted on 22 Sep, 2010 08:03 PMThis presentation by ACWADAM deals with the importance of groundwater. It is well-known fact that groundwater forms a very crucial source of water supply in the national scenario on water resources today. And yet, it continues to remain a resource that is both abused and misused. Often, watershed projects suffer from insufficient inputs, especially hydrogeological to address the problem(s) of groundwater within the watersheds.
India’s groundwater typologies – A presentation by ACWADAM
Posted on 22 Sep, 2010 08:01 AMThis presentation by ACWADAM deals with groundwater typologies in India. The typology of groundwater can be defined in many ways based on a) Uses of Groundwater, b) Geography, c) Geology, d) Hydrogeology (Aquifers), e) Groundwater Quality, f) Stage of Groundwater Development, and g) Socio-ecology of Groundwater.
Geological mapping – A presentation by ACWADAM
Posted on 21 Sep, 2010 08:27 AMThis presentation by ACWADAM deals with geological mapping. The occurrence of water within a watershed is governed by the rock types occurring both at the surface and within the subsurface, their sequence and their structure. The physical structure which plays host to the water within the watershed is geological. Every watershed programme must therefore include a fundamental understanding of this framework so that the development and management measures planned through such programmes are meaningful and properly justified technically.
Groundwater management under the climate change scenario in India – A presentation by ACWADAM
Posted on 20 Sep, 2010 08:17 AMThis presentation by ACWADAM deals with the issue of groundwater management under the climate change scenario in India. Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. The causes are -variations in solar radiations, plate tectonics, volcanism and change in earths orbit & axis.
