Storm Drainage Design Project - Essay Example ertical axis using different scales, but their horizontal coordinates are the same based on hourly readings from the midnight of October 12 to 11:00 in the evening of October 15, 1998. Rainfall data was plotted using millimetres (mm) and the given observations were used as is. On the other hand, river data, which is usually plotted as a discharge in a unit of volume against time (cubic meters per second or liters per second) is drawn as a function of the given river width (B) and the velocity (V) of flow of the river (since discharge is a product of area and water flow velocity in this case) per hour of observation. The highest point (peak) of the blue line graph is 0.658 meter-BV per hour. The scale used was 1 x 10-1 m, such that 0.658 is represented as 6.58 x 10-1 m. This should explain why the highest number in the vertical axis is 7. It may be gleaned from Figure 3 that although observations were plotted every hour, the time markers were presented every three hours due to space limitations.). However, the data were analyzed using the original values and units of the river level per hour of observation. Prior to the rainfall in 4:00 on October 13, the average reading of the river height from the start of given observations for 28 consecutive hourly readings is 0.262 mm. This will be the basis of the base flow. After seven hours of rainfall, the first peak was observed at 11:00 of October 13 with a height of 1.2 mm. This marks the initiation of the rising limb of the river flood where the height of the river also started to rise compared to base flow. The rainfall data had twin peaks, with the second peak occurring at 21:00 of October or 10 hours after the first rainfall peak was observed. At 9:00 of October 14, 12 hours after the second peak of the rainfall, the peak flow of the river was recorded at 0.658 m. The amount of time for the peak flow to return back to base flow or base flow time is 46 hours. Several factors which influence the characteristics of

POLITICS - Essay Example (2003) political ideas and ideologies can act as a kind of social cement, which in turn could provide social groups with a set of unifying beliefs and values. In this regard one could consider that governments are set up to help provide a relatively unified set of codes by witch to govern a society. In the American context one could present the argument that the ‘First Continental Congress’ which was a meeting of twelve of the thirteen original colonies which banded together to present grievances to the British Monarchy was the original congress. However it was the second continental congress which met again in 1776 which declared the colonies free, effectively beginning the American Revolution and in turn was the entirety of the United States government. According to English (2003) it is the case that the original congress held such responsibilities as directing the war, commerce, the enforcement of laws, however they were not free to collect taxes and held the key distinction of allowing the independent colonies (States) the ability to remain sovereign and as such they would effectively be free to ignore any legislation passed by congress. As one would naturally assume, this system was rife with flaws. In this regard a kind of compromise was made in which a house of representatives was established in which officials would be elected directly by the people based on the population of the states and the senate would provide a type of equal representation by the state regardless of population. Now it is the case according to Davidson et al. (2006) that the United States congress has a number of direct powers identified in the United States Constitution however there are a number of implied powers which owe their nature to the Necessary and Proper clause. In general the congress handles affairs pertaining to the setting and collection of taxes, defense, the paying of debts, regulation of commerce, the establishment of courts (lower than the Supreme Court). It
