Flood forecasting

Data is selected only from July to October, especially in flood stage water level forecasting. This is the usual monsoon flood season in Myanmar and most Asian countries. Descriptive statistics were calculated to characterize changes in the Mawlaik Observatory's water level. As shown in Figure 2, the data is slightly distorted, but the frequency distribution is almost normal. The Kolmogorov-Smirnov test is also used to numerically check the normality of data of size 2706.

Kerala lacks a flood forecasting system: Kerala is vulnerable to heavy rains and floods, but lacks an adequate flood forecasting system. The central water committee (CWC), India's only flood forecasting institution, lacks information on flood conditions in Kerala. Local residents have no room in advance for the situation, so this makes the situation even worse. CWC has a flood monitoring site in the state, but some sites are not functioning. Excessive release of excess water from dam: More than 20 dams released large amounts of water and exacerbated the situation when Kerala already dealt with serious floods. Why did not you free water before? What does the authorities do before the monsoon arrives in India?

Indian flood prediction and flood warning began on a small scale in 1958 and a unit for predicting the flood of the Yamuna River in Delhi was set up in the Central Water Commission of New Delhi. It covered most of the interstate watersheds prone to floods. Currently, the Central Water Commission has issued flood forecasts of 173 places, 145 flood forecasts and 28 forecasts for inflow prediction. On average, about 6,000 flood predictions are announced annually and in 1998 up to 7,943 floods forecasts were made. According to the current regulations of the Central Water Commission, the forecast issued by the Central Water Commission meets the accuracy of about 96%. If the difference between the predicted river level and the corresponding observed river level is within ± 15 cm, the prediction is considered to be fairly accurate.

Among all nonstructural measures of flood management that rely on changing susceptibility to flood hazards, more / sustained attention and publicly accepted measures gained by the planner are when floods are used by the river District that allows early warning of, how much, how long. Regarding strategies that place greater emphasis on nonstructural measures, the Central Water Committee has established a nationwide flood prediction and alarm system.
