Aquifer. Types of Aquifer.

What is an Aquifer? An aquifer is a body of saturated rock through which water can easily move. Aquifers must be both permeable and porous and include such rock types as sandstone, conglomerate, fractured limestone and unconsolidated sand and gravel. Fractured volcanic rocks such as columnar basalts also make good aquifers. The rubble zones between volcanic flows are generally both porous and permeable and make excellent aquifers. In order for a well to be productive, it must be drilled into an aquifer. Rocks such as granite and schist are generally poor aquifers because they have a very low porosity. However, if these rocks are highly fractured, they make good aquifers. A well is a hole drilled into the ground to penetrate an aquifer. Normally such water must be pumped to the surface. If water is pumped from a well faster than it is replenished, the water table is lowered and the well may go dry. When water is pumped from a well, the water table is generally lowered into a cone of dep

Folding is a concept that embraces all geologic processes by which surfaces in rocks become curved during deformation

Folding is a concept that embraces all geologic processes by which surfaces in rocks become curved during deformation. Since folds are permanent deformation structures with no or little loss of cohesion of the folded layer, folding refers to the essentially slow, ductile behaviour of relatively soft and/or hot rocks. Beyond the descriptive, anatomical classifications, much of the early geologic work on folding processes focused on the deformation of stratified sediments. Different folding mechanisms combine a few basic processes involving the geometrical (layer thickness and spacing) and physical (viscosity, viscosity contrast, anisotropy) properties of the rocks. This lecture deals with some consideration on genetic, mechanical aspects concerning the development of folds. The important point to note is that stress alone is insufficient to cause folding: A planar surface must first exist to define the fold shape, and the orientation of this planar marker with respect to the stress dir

Internship @ National crop forecast Centre. #GIS Remote Sensing #Geography.

#Internship @ National crop forecast Centre. #GIS Remote Sensing #Geography. The internship programme will provide an opportunity for the officers of the MNCFC to interact with young thinking minds with brilliant academic record from reputed institutions. Ideas from budding scholars will prove to be of importance to the practitioners of Remote Sensing in the MNCFC. At the same time, the internship programme will also provide the interns with an excellent opportunity to familiarize themselves with the applications of Remote Sensing (RS) and GIS in Agricultural Assessment. (b) The interns may benefit by getting exposure to advanced RS & GIS Data Analysis and Forecasting Data analysis procedures at MNCFC and contribute to development of techniques for improving agriculture assessment. (c) MNCFC may benefit from the additional resources in the form of young talent and their new ideas may add to MNCFC forecasts.

Watershed demarcation. Topographic Map. Soi topo sheet. Watershed Management and Modelling.

Drawing Watershed Boundaries When we talk about the hydrologic cycle and the water budget, we typically talk about these things in terms of watersheds. So first you should know what a watershed is. Watersheds are topographically defined areas –something like bowls. What we mean by that is that a watershed is separated from neighboring watersheds by high points on the landscape. You can think of a watershed as an area that, if precipitation falling into it was not evaporated back to the atmosphere and did not infiltrate into the soil, all of the water in the watershed would run downhill to the same stream. Delineating watershed boundaries. All watershed delineation means is that you're drawing lines on a map to identify a watershed's boundaries. These are typically drawn on topographic maps using information from contour lines. Contour lines are lines of equal elevation, so any point a

Weather and Climate.

Good morning. Good day. This is Vineesh. Welcome to our our class. Today's topic of discussion is about Weather and Climate, a simple and interesting topic. We all know that Geography is Spatial science deals with Man, earth and environment. Now a days we people are studying about Different spatial process and patterns. Weather. Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere. Weather is the mix of events that happen each day in our atmosphere. Weather is different in different parts of the world and changes over minutes, hours, days and weeks. Most weather happens in the troposphere, the part of Earth's atmosphere that is closest to the ground. Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for
