Geological Investigation of Dams and Reservoirs

In order to detect geological flaws and to select a suitable site for the construction of dams and reservoirs, deep geological investigation of that particular area is carried out. The prime objective of this investigation may be summarized in the following lines. Physiographic features of that particular area are studied during the geological investigation. The …

Geology of Reservoirs

Reservoirs are artificial lakes, which are created by the construction of dams across rivers. A reservoir may fail either due to excessive leakage of water or as a result of rapid sedimentation or rupture due to earthquakes. Problems associated with Reservoirs:  The main geological problem connected with the reservoirs are: (i) groundwater conditions, (ii) permeable …

Problems associated with Dams/ Failure of Dams

Some of the most common and frequently occurring problems associated with dams are the factors, which cause a dam to fail. Most of the dam failures, which have occurred in the past are not due to faulty design or poor construction, but mainly due to neglect of the geological flaws. The main geological problems that …

Geology of Dams

Dams Dams are a common and cheap means of storing water. Dams are constructed as barriers across the rivers thereby storing their water. They are built mainly to control floods, for irrigation lands, for generating electricity and supplying water to industries and cities. A dam that serves more than one purpose is called a ”multipurpose …

Different types of rocks used as building stone

As in the earlier post, it is mentioned, that the usage of rocks as building stone is totally dependent on their strength and durability. Some of the properties which make the rocks eligible for usage as a building material are their strength, permeability, durability, and resistance to heat. Keeping in view these properties geologist chose …

Geology and Civil Engineering

Mining is an important branch of geology, and it has been known for a long, but its use in ”civil engineering” has been recognized only in comparatively recent years. The importance of geology in civil engineering may briefly be outlined as follows: We can derive a systematic knowledge of construction by means of geology. The …

Formation of Mountains

Formation of Mountains: Since the world’s major mountain systems belong to the class of fold mountains, their process of formation is of great importance. While discussing the formation of fold mountains, the following points may be noted. (i). The great mountain ranges are build of thick sequences of sedimentary rocks, which are usually highly metamorphosed …

Mountain Building

What are mountains: The highlands, which rise up to several hundred meters or more above the surrounding terrain. Large mountain systems generally show evidence of enormous forces, which have folded, faulted, and deformed large sections of the earth’s crust. (1). Orogenic Movement: The crustal movement, which results in the formation of the mountain system, are …

Denudational Landform

What is denudation: Denudation is the combined action of erosion and weathering. Weathering is the breaking of rock particles from it, while erosion is the transportation of these separated particles away from the parent rock. The processes of erosion and weathering are, collectively, called denudation. In other words ”denudation means” means the separation and transportation …
