- As a non-structural measure, flood forecasting (such as discharge, water level, or flow volume) is a crucial part of flow regulation and water resources management. Worldwide, flood disasters account for about one-third of all natural disasters in terms of number and economic losses (Berz 2000). As stated by Dutta and Herath (2004), out of the total number of flood events in the world during the past 30 years, 40% occurred in Asia and Southeast Asia countries stand for the second worst region in Asia....

- Table 1 shows the statistical parameters of calibration and validation data. The maximum value of calibration period was larger than that of the validation range while the minimum value was less than that of validation. Thus, extrapolation problems may not exist in this data set. The skewness in both calibration and validation data sets are not drastically different. At the forecasting station, the autocorrelation and partial autocorrelation functions of water level with corresponding confidence limits were estimated up to 20 lags as shown in Fig....

- Weather forecasting can be defined in so many ways; one of such ways is the application of science and technology to predict the state of the atmosphere for a future time and a given location.” Although the concept of weather forecasting seems exciting weather forecasters are taken for granted; people fail to realize that they have so much to contribute to the economy. ‘’Is it possible by any means to make weather predictions beyond one or two weeks’’. According to Matthew E. Kahn it has been proven, atmospheric scientists reports of long range climate forecast that are among the best that they have ever had, been able to predict climate for up to six months in advance....

- During the past 30 years, 40% of the total number of the flood events in the world occurred in Asia, whereas Southeast Asia is the second worst flood-affected region of the continent, after South Asia (Dutta and Herath 2004). Consequently, risks to lose human lives, goods and environmental assets are increasing. Therefore, understanding flood response characteristics and flood estimates are required not only for design and economic appraisal of hydraulic works, but also for efficient flood management schemes.Myanmar, the second biggest country in Southeast Asia,is highly exposed to flood hazards due to its complex topography and high rainfall intensities during the southwest monsoon season.I...

- Planet Earth is a miracle, an anomaly within our universe that allows for the growth of diverse natural organisms and beautiful scenery. However, with this great beauty comes natural hazards that can be detrimental to the continued survival of the organisms that inhabit the surface and oceans alike. These disasters can arrive with little warning and completely disrupt the operation of society. The need to plan for potential complex emergencies will continue to rise as long as natural hazards continue to occur along with the human population increasing and seasonal weather intensifying with climate change....

- i)Graph1.1 ii) The time series exhibits a fair degree of volatility or randomness.The underlying level of the series over the given time period appears to be well contained in an underlying band of 0.9250-0.9450. The level of this time series also appears constant over the entire time series and hence a horizontal data pattern is observed. Since the time series is relatively horizontal with trend and seasonality not apparent in this time series, then moving average and simple exponential smoothing would be possible predictors for future days USD/AUD exchange rates....

- Forecasting Methodology Forecasting is an integral part in planning the financial future of any business and allows the company to consider probabilities of current and future trends using existing data and facts. Forecasts are vital to every business organization and for every significant management decision. Forecasting, according to Armstrong (2001), is the basis of corporate long-run planning. Many times, this unique approach is used not only to provide a baseline, but also to offer a prediction into the corporation's future.... [tags: Business Forecasting ]

- Introduction All businesses are confronted with the general problem of having to make decisions under conditions of uncertainty. Management must understand the nature of demand and competition in order to develop realistic business plans, determine a strategic vision for the organization, and determine technology and infrastructure needs. To address these challenges, forecasting is used. According to Makridakis (1989), forecasting future events can be characterized as the search for answers to one or more of the following questions: X What new economic, technical, or sociological forces is the organization likely to face in both the near and long term....

- Forecasting Methods Forecasting demand is not an easy task. The market is constantly changing and it makes the product demand difficult to predict. Therefore, there is not such as perfect product forecast of what customers will need in the future. However, there are several methods that help attenuating the uncertainty of forecasting demand. Since, the forecast methods or techniques differ from one another; the objective is to compare and contrast several forecasting methods, and how they are used by organizations to the best advantage under conditions of uncertainty....

- Macroeconomic Forecasting Abstract Annual data was gathered on the United States' Gross Domestic Product and the economic indicators of unemployment, employment growth, inflation, and interest rates. Using 2004 as the base year, forecasts for the next two years were taken from three different forecasting organizations and compared to historical figures. Differences in projected data were addressed as well as relationships between forecasts and among the targeted indicators. The results of the economic forecasts were applied to current Motorola operations and plans.... [tags: Economics Business Forecasting]
