Severe Rain Fall Alert

Introduction

Severe Rain fall Alert takes place when the rainfall is in severe situations. Due to the heavy rainfall, the agricultural sector was mainly damagesand also the country’s economy was also damaged within hours of the severe rainfall. When the rainfall is severe in the states, it damages the state economy and also damages the Gross domestic product of the state’s population. In all seasons, the monsoon season is the most of the economy of the state is heavily, occupied, dependent on the rainfall. Because the rainfall plays a major role in the formation of the irrigation field projects, dams, and also in the flood control measures based on the rainfall statistics. The flood management system takes measures to study the situations of the droughts in three severe rainfall alerts.

Rainfall Definition

The amount of rainfall received in the area of the given area over a given time is known as the Rainfall. The rainfall is measured by using the instrument of Rain gauge. By collecting all the data, the management analyzes the rainfall volume and also starts their development works in the water resources, like the construction of the irrigation projects, and also develops many agricultural development works. Mainly, the management of the groundwater departments analyzes the rainfall level statistics and they recharge the groundwater for the usage of future.

Severe Rain Fall Alert — Severe Rainfall Alert

Rainguage

It is one of the main measurements used in the usage of measurement of rainfall size, length, and volume.
It is in 200 sq cm with a diameter of 159.6 mm, not recording the rainguage. It consists of three parts of the non-recording rainguage Base, the Collector, Bottle. The collector is also known as the funnel.
This rainguage is with 100mm and 200mm capacity provided with the cylinder, to restrict the overflow of the bottle.
The collector and the bottle have been locked with a set of two locking parts.
The permanent lock of the rainguage is with the help of the hasp and the staple with a padlock.
The whole rainguage is made of the fiberglass-reinforced polyester material with the Indian Standard Specifications.

Rainguage Erections

By the masory and the concrete foundation with 60 cms x60 cms sunk, the rainguage fixed in the ground. In this masonry foundation, the rain gauge is fixed so that the gauge rim is level above 30 cm in a perfect level. This type of height prevents the rainfall water for the gauge if overlly. If we see that the amount of heavy rain is collected, the wind eddies decrease on their own. Keep the rim in perfect horizontal shape because it decreases the effective area of the funnel and also the rain collected reduces rapidly.

Rainguage protection

The management must keep an eye on the rainguage because if we neglect the rainguage we cannot estimate the value of the rainfall.
For the protection fence, it should be placed around the rainguage from animals and people, and birds to protect it from anything
To prevent everything, it should placed a distance between the ground like 18-20 cm should be placed entering the other particles
The fence height must also be placed above the rim of the gauge and not fixed more than one-fourth distance from the gauge
Rainguage must be placed on the ground level, not on uneven land or slopes
It should in the ground level that falls easily in the direction of the prevailing wind.
Based on these precautions, taking the details and also sharing the details with the rainfall authority for speedy reactions, alert to protect the people.

Rainfall Measurement

It was measured with a rain gauge instrument in terms of the depth of the water, level area, size, and volume. which falls into the gauge. For measuring the rainfall, the first step is to collect the water in the receiving bottle. Then pour the rainfall water into arranging plastic cylinder/glass to count or measure the rainfall. Place it on a level surface. Care must be taken to avoid the spilling of the collected water from the rainfall. For each time, the cylinder shows 0.2 mm, and the observer counts the number of levels covered by the water. The lower surface of the water in between the two divisions, the rainfall should be analysed to the nearest 0.1 mm. The observer must note the observations in a record at 8:30 hrs every day. By these recordings, they submit the information to the statistical officers.

Observations of Rainfall

The rainwater must be measured every day at 8:30 hrs in the rain gauge. If there is no rain, the IST and the rainguage should be analysed every day for information about the nature. The measurement observations must be made three to four times on a heavy rainfall day. In a day, the total measurements in 24 hours from this information. They know whether it is heavy rainfall or normal rainfall. The observation should be made quickly if it is on a rainy day to avoid natural damage. When the rainfall is heavy, place the glass bottle and receiver for the collection of the heavy rainfall. After taking the receiver or glass bottle and pour the collected water into the original receiver for the measurement observations.

IMS Procedures

The IMS had decided the measure the rainfall at 8.30 am all over the country for uniformity.
And it is an easy way to know all the weather reports at the same time in the country at that time every day
And mainly to restrict the consequences of the damage to the rim and the funnel, the collector follows the procedures of the IMS.
Gently with one hand, the observer should remove the funnel.
And also with one hand, the receiving bottle should be taken out
Replace the funnel after measurement, and remove the funnel with one hand. On the other hand, restore the receiver bottle in the rainguage in the position
Replace the funnel in its position properly and lock the funnel for safety measures.

Normal Rainfall

The normal rainfall is calculated by comparing the average rainfall data with the long-term data. The rainfall at normal state should be calculated within the years of 1901-1970 rainfall data. The normal rainfall data should be calculated in 438 rain gauge stations, like revenue, PWD, and IMD stations. And in 217 stations, the normal daily rainfall data is calculated. The officers pay attention and monitor the drought conditions areas from the down level in the mandal, states, and country. And the directorate of the economics and statistics in the rainguage for every mandal, state, and country.

Safety Measures in Rainfall

Pay attention to the words of the weather officers and the management during rainfall, flood warning situations.
If your house is in a low area, shift your place to higher locations.
If the rainwater enters your house, you may clear the water outside. To avoid having more severe effects on your family
Do not drive outside when the weather conditions are bad. As it will leave you stuck in any place or any accidents to occur in these conditions
Check the house if they are any kind of water leaks, paint discoloration. And if you find them, repair them as soon as possible
Cut the big branches of the trees from your house, they may fall on your house during the storm, or rainfall
Move your furniture safely to the higher places before the severe rainfall
Take the insurance for the future if you have lost any kind of furniture, etc, it will help you for a speedy recovery
If the rainwater enters your house, you may clear the water outside to avoid having more severe effects on your family
Check the roof conditions of your home before the rainfall. If any damage is located in your home, repair it as soon as possible.
Arranging the supply of food, shelter, water, and other facilities in emergency situations must be the responsibility of the rainfall
