Rock properties are the uncontrollable variables in surface blast design operation. Blast performance is influenced by the geological structure and the rock strength. Practically in every mining practice, rocks are non-homogeneous in nature. Geological discontinuities like joints, fracture, foliation, bedding planes, have a major effect on blasting performance. Joints are defined as planes of weakness within a rock mass along which there has been no visible movement.
Swash zone gradients range from 2°- 6°, steep swash zones are characteristic of beaches undergoing accretion and also indicate degrading berms. While the swash zone and berm usually seem parallel to one another, at times the boundary between them may be thrown into seaward facing concave cups. Beach cups may be observed during the monsoon and inter-monsoon seasons especially where the swash zone is developing at the expense of the
• To examine the suitable bicycle frame and design of floating for the amphibious cycle. • To examine the safety of the driver and passenger. Scope Aim of Research: To develop an autonomous amphibious vehicle with suitable single locomotion mechanisms to allow the vehicle to navigate effectively on both land and water. The research objectives are as follows: • To develop an amphibious vehicle for confined and narrow areas using suitable steering configuration and maneuvering system. • To improve the efficiency of water propulsion for wheel-based vehicle by optimizing its water thruster design by cutting down the extra load for a separate thruster drive.
It is an extensive analysis that has led to an important classification of beaches that is applied worldwide for decades (Davis & Fitzgerald, 2004). Median size diameter (D50) and swash slope are among the key parameters taken into consideration in order to classify the beach state (Carter, 1988; Short, 1999). From the data gain of both parameters however, only swash slope gives a strong effectiveness of morphodynamic classifying for the visual classification of Wright & Short (1984). The classified beach types are presented in Table 7.6. It could be generally defined that the beaches along the Pahang coastal region are classified as an intermediate and dissipative state.
To determine the height of the water in the harbor, use the equation . Y = 5.8 sin (0.52x+0.20) + 6.5 where x represents the number of hours since midnight. Analysis and interpretation: Input the value of x into the equation to find the height at a particular time. At midnight, the value of x is 0. Putting 0 in for x in the equation gives you Y = 5.8 sin (0.20) + 6.5 = 7.65 And at the greatest height at π/2 Y = 5.8 sin (0.52 π/2 +0.20) + 6.5 = 11.94 ≈ 12 So it makes sense that the high tide would be when the formula uses the sine of that value.
However, did you know how cloud form? Basically, there are various type factors that help to form a clouds and each of these will create different type of clouds. Firstly, clouds form due to the amount of water in the air have increased. This circumstance also knew as evaporation. The evaporation happened in a situation which the sun lights radiate the oceans, lakes, ponds, rivers and other watery areas.
7,8 and 10). Most hurricanes form in the Atlantic Ocean because of the above mentioned conditions. When a hurricane is situated in warm water, the intensity of the storm increases because the warm water is the main source of energy along with the moist atmospheric conditions. Hurricane frequency depends heavily on what is called an El Niño. “El Niño refers to appearance of anomalously warm water along the coast of Ecuador and Peru as far south as Lima (12°S)” (Trenberth, 1997, p. 2771).
P waves is a longitudinal or compressional waves that can travel through solid and liquid, whereas S waves is a transverse wave that can only travel through solids. Surface waves are both longitudinal and transverse wave and it move in a direction that is both parallel and perpendicular to the direction of wave motion. The P waves causes the particle of rocks to vibrate forward and backwards in the direction of the waves. On the other hand, S waves causes the particles of rocks to oscillate at right angles to the direction of waves. When P and S waves reached the surface of the Earth they get converted into long waves that travel along the surface, vibrating horizontally at right angle to the direction of the waves are called “Love Leaves” or “Rayleigh” waves as they also travel like a sea waves.
CHAPTER 5 VARIATION IN TEXTURAL CHARACTERISTICS OF BEACH AND NEARSHORE SEDIMENTS Introduction The alternate changes of sediment in the beach territory play a great role in determining the morphological response in coastal regions. Changes that involve the movement of particles from one place to another is the key factor in altering the morphology of the beach; include the loss and gain of sediment and influence the formation of beach surface. Therefore, studies related to sedimentological characters become more crucial nowadays as the nature of the beach surroundings are sensitive and delicate which often deals with dynamic equilibrium (Carranza-Edwards et al., 1998). The textural characteristics of sediment of recent coast reflect the sedimentary
Along with these, the rise and fall of tide is something, which is very important for fishing occupation. The rise as well as fall of the levels of sea is caused because of the gravitational forces that exerts from Moon and Sun as well as the rotation of the Earth are known as the tides. They are the vertical movement of water in the sea, river, ocean etc. There are some seashores, which experience two high, and low tides in 24-hour period. When the tide rises, it is known as flooding and it is called as ebbing when the tide is falling.
