Assessment of Drought Years Drought can be defined as a temporary harmful and widespread lack of available water with respect to specific need. It implies a deficiency of rainfall of sufficient magnitude over a prolonged duration so as to interfere with some phases of regional economic activities. According to the India Meteorological department (IMD) an area / region is considered to be drought if it receives seasonal total rainfall less than 75% of its normal value. In the present study attempt has been made to assess the drought situation in Agra district of U.P. Agra is an important district in northern region of U.P., where the occurrence of recumbent drought have badly affected the agricultural production and economy of the area. The rainfall records for the Agra district were obtained from the India Meteorological department (IMD). Rainfall data has been subjected to various kind of analysis including seasonal & annual rainfall departures, probability distribution and dry spell analysis etc. MATERIAL AND METHODS The daily rainfall data of thirty four years (1970 to 2000), the rainfall records for Agra district were obtained from the India Meteorological department (IMD). The Agra district is located on the bank of river Yamuna in the northern region of Uttar Pradesh and lies between north latitude 27º11' to 27º19' and east longitude 78º01' to 78º02' and elevation of above 63.4 m above mean sea level. The main occupation of the district is agriculture and pearl millet, sorghum and potato are the chief grown crops. The average annual rain fall in Agra is 663.8 mm. the rainfall in this track is received from south western monsoon. According to the India Meteorological department (IMD) an area / region is considered to be drought if it receives seasonal total rainfall less than 75% of its normal value. Rainfall data has been subjected to various kind of analysis including seasonal & annual rainfall departures, probability distribution and dry spell analysis etc. Calculation of departure Step-1 - Take the annual discharge data (mm) of any district. Step-2 - Firstly we will calculate the mean of annual rainfall data. Step-3 - Now we calculate the standard deviations, skewness, maximum, minimum and median of the rainfall data. Step-4 - For calculating the departure we will substrate the annual rainfall data of a year from the mean rainfall of the year. Step-5 - Now we will find out the 75% of mean rainfall. Step-6 -Then we calculate the drought year .for calculating the drought year we will to compare the annual rainfall .if the value of annual rainfall of year with 75%of mean rainfall, then it is called drought year but if the value of annual rainfall of year is greater than the 75% of mean rainfall then it is called the no drought year. Step-7 - After calculating the drought year, we calculate the departure from mean rainfall. It is calculated with help of below given formula. Departure from mean rainfall = (annual rainfall of year - mean rainfall) / Mean rainfall*100 Step-8 - Finally we will calculate the class of severity of the particular

Shri Kant et al., 64 block. If the value of departure from mean rainfall is less than -25% then no drought condition, but if the value of departure from mean rainfall is coming between the -25 to -50%then it is called the moderate drought condition. If the value is generate then -50% then

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
