This document discusses methods for groundwater exploration, including the lithological method. It begins with an introduction about groundwater and the need to explore new sources as existing shallow sources are depleted. The objectives of groundwater exploration are to identify locations where it is available through regional and detailed surveys. Surface exploration methods are described, including the lithological method of studying rock characteristics. Key concepts like porosity, permeability, lineaments, faults and joints are also explained in the context of understanding subsurface groundwater distribution. The conclusion states that lithological analysis is a basic first step to aid other exploration methods.
The subsurface occurrence of groundwater may be divided into zones of aeration and saturation. The vertical distribution of groundwater is explained in this module.

Over the last decade, demand for spring management has increased as traditional spring sources have started drying up or becoming contaminated. In response, communities, NGOs and state agencies began dedicated spring protection programmes. In the Himalayas, the State of Sikkim and organizations such as Central Himalayan Action and Research Group (CHIRAG) and People Science Institute (PSI) started identifying and protecting spring recharge areas around 2007. The difference between these programmes and many other previous efforts is that they went beyond supply-side improvements to focus on the use of hydrogeology to map springsheds for targeted interventions.
The Advanced Centre for Water Resources Development and Management (ACWADAM), a research and capacity-building organization comprised of hydrogeologists and other experts began lending their expertise and building capacity of stakeholders. ACWADAM provides technical support, training and materials in hydrogeology to all network partners as well as others in India and the region. Similar programmes began independently in most of the mountain regions of India. Arghyam, a funding organization that was supporting many of these programmes, noticed that these disparate initiatives shared commonalities despite geographic diversity. They thus organized and funded a meeting of these various organizations in June 2014, and the Springs Initiative was born.
The springs initiative aims to tackle the current water crisis and to ensure safe and sustainable access to water for all, by promoting responsible and appropriate management of aquifers, springsheds, and watersheds and conserving ecosystems in partnership with communities, governments and other stakeholders.
This presentation has been developed as a part of the springs initiative to promote an understanding of springs and their role in mountainous areas.
A pumping test is a field experiment in which a well is pumped at a controlled rate and water-level response (drawdown) is measured in one or more surrounding observation wells and optionally in the pumped well (control well) itself; response data from pumping tests are used to estimate the hydraulic properties of aquifers, evaluate well performance and identify aquifer boundaries.

Identification Of Soil Erosion Prone Zones Using Geomatics Technology In Part...IJERA Editor
Soil erosion is the removal and subsequent loss of soil by the action of water, ice, wind and gravity. Soil erosion is a process that occurs naturally at a slow rate. The average natural geologic rate of soil erosion is approximately 0.2 tons per acre per year. Erosion is the process were by the earth or rock is loosened or dissolved and removed from any part of earth‟s surface. Geological erosion is the rate at which the catchment or land would normally be eroded without any disturbance by human activity. If man alters the natural system by means of various land use practices that is caused accelerated erosion. The present study area is covering Parts of North Arcot The area is lies between E78°30'-E78°45' lattitudes N12°15'-N12°30„. The total aerial extent of the study area is 720 sq.km. It falls in the survey of India Toposheet 58 L11 on 1:50,000 scale. The IRS – 1D satellite imagery data were subjected to different types of image enhancement techniques and soil erosion areas were mapped out and GIS databases were generated showing the soil erosion areas using Arc Map 9.1 version. GIS overlay function was executed between soil erosion prone areas and the various controlling variables and the area has been fragmented into a number of polygons of land segments depending upon the controlling variables. Finally, the remedial measures were suggested for each land segment according to the controlling variables.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

CONCLUSION.
3. Introduction
Groundwater is an invisible natural resource. It is
available in different proportions, in various rock types
and at various depths, on the surface layer of the earth.
4. More than 60 percent of the global population thrives
by using only the groundwater resources. The
groundwater which was existing at shallow depths in
the open wells, has gone deep due to over-
exploitation.
Exploring these water sources become a challenging
task to geo-scientists.
5. GROUND WATER EXPLORATION
Though the ground water resources are widely
distributed, Nature does not provide ground water at
the places of our choice.
The occurrence and distribution of ground water
resources are confined to certain geological formations
and structures.
The ground water at all locations may not be directly
used if the quality of water is poor.
All these problems can be solved using proper
exploration techniques.
6. Exploring groundwater
Identifying the location of its availability is a
challenging task.
Exploration of groundwater requires a basic
understanding of its position in the subsurface
geological setup.
Groundwater Exploration is attempted through either
by direct or indirect methods.
Test drilling is the direct approach to find out the
resource. This is an expensive affair.
7. OBJECTIVE OF GROUND WATER
EXPLORATION
Usually the ground water exploration projects
pass through the phase of regional surveys,
leading to detailed surveys and ultimately
resulting in the exploitation of ground water
by means of bore holes, wells.
8.
9. Surface methods
The surface methods are easy to operate and implement.
These require minimum facilities like topo-sheets,
maps, reports, some field measurements and
interpretations of data in the laboratories. The surface
methods of groundwater exploration include the
following:
–Geomorphologic methods
–Geological & structural Methods (Lithological method)
–Soil and Micro-Biological Methods
–Remote Sensing Techniques
–Surface Geophysical Methods
10. LITHOLOGICAL METHOD
LITHOLOGY
The study of the general physical characteristics of rocks.
The general physical characteristics of a rock or the rocks
in a particular area.
11. As we know that lithology is the study of rock or rocks
in particular area, so to understand the sub-surface
features we need to know study the surface features
(outcrop).
The study of rocks in the area that include physical and
chemical characteristics.
12. Origin of ground water is mainly through
Precipitation
Infiltration
Recharge
To exploit the ground water we need to understand
that the good water bearing rocks in the particular
area, the type of rock and their permeability and
porosity and also joints, lineaments and folded
structures of the rocks and rock beds.
13. Porosity and Permeability
Porosity is a measure of how much of a rock is open
space. This space can be between grains or within
cracks or cavities of the rock.
Permeability is a measure of the ease with which a
fluid (water in this case) can move through a porous
rock.
16. Lineament
Natural lineament can be generally defined as linear
feature on the earth surface visible on the map.
Lineaments are the result of heterogeneity (anomaly)
of physical/chemical/biological properties underneath
(faults and fractures in the first place).
17. Fault and Joints
Structures as hydrodynamic contacts impact on the
groundwater flow pattern of an aquifer, as well as,
the major structural features impacting on
groundwater are fractures and folds. Fractures are
subdivided into joints, fissures and faults, which are
formed by brittle fracturing of rocks.
18. Lithology of the area is to be supplemented and by evaluation
of available hydrologic data on stream flow and springs, well
yields, groundwater recharge, discharge, and levels and water
quality. In some places, the drainages may be fully controlled
by the presence of minor and major structures like joints,
faults and lineaments. Such zones are good and potential
zones for groundwater exploration.
19. Contact points between permeable water-bearing
strata overlying relatively impermeable strata usually
along the sides of valleys that cut across the interface
between different strata are suitable locations for
groundwater. Springs occurring on or near the base of
hillsides, valley slopes, and local scarps are indicators
of groundwater occurrence over hilly terrain.
Dykes are good barriers for arresting the flow of
groundwater. Location of dykes and analyzing their dip
and strike help in selecting the groundwater potential
zones in the upstream side.
20. CONCLUSION.
The lithological methods of groundwater exploration
is the basic method of exploration by studying the rock
features in a required area.
By studying the lithology of the area we go for other
methods of exploration for to understand the
groundwater situation in the subsurface clearly.
