Derivation Of Intensity Duration Frequency Curves Using Short Duration Rainfa...Mohammed Badiuddin Parvez
The estimation of rainfall intensity is commonly required for the design of hydraulic and water resources engineering control structures. The intensity-duration-frequency (IDF) relationship is a mathematical relationship between the rainfall intensity, the duration and the return period. The present study aimed the derivation of IDF curves of Yermarus Raingauge Station of Raichur District with 19 years of rainfall data (1998 to 2016). The Normal Distribution, Log Normal Distribution, Gumbel distribution, Pearson Type III Distribution and Log Pearsons Type III Distribution techniques are used to Find the rainfall intensity values of 2, 5, 10, 15, 30, 60, 120, 720, 1440 minutes of rainfall duration with different return period. Chi Square test was conducted to find the goodness of fit the short duration IDF using daily rainfall data are presented, which is input for water resources projects.

This paper is mainly concerned with Statistical analysis of the trend of hydrological data viz. rainfall data. The rainfall trend of a region plays a vital role in the charm of its climatic situation in respect of tourism as well as local livelihood. In this case study the monthly rainfall data mm of 67 years 1951 to 2017 of the Lakshadweep meteorological subdivision has been processed to analyze its trend by nonparametric Statistical analysis. The Mann Kendall trend test and the Sen’s Slope estimator are used to determine the monotonic trend of rainfall and its magnitude respectively. In this study, monthly and average annual trends have been considered. Winter, pre monsoonal, monsoonal, post monsoonal trend are taken into consideration. In this paper, results show the average annual rainfall is 130.67 mm whereas for winter season, pre monsoon season, monsoon season and post monsoon season, the average rainfall are 29.95 mm, 70.36 mm, 249.09 mm and 135.39 mm respectively. The trend of average annual rainfall is significantly upward, i.e. increasing similar to winter season and monsoon season. The decreasing trend is found in pre monsoon and post monsoon seasons. The impact of rainfall on local livelihood is also discussed here. R Version 3.6.1 Statistical software is used for analysis purposes.

Evaluation of Groundwater Quality and its Suitability for Drinking Purpose in...ijtsrd
Groundwater is a necessary and essential element of any existence support system. It is not only the basic need for human survival but also a compulsory input for all development activities. This study was carried out to analysis factors regulating quality of groundwater in an area with drinking as main use. Sixty groundwater samples twenty form each year 2013, 2014 and 2015 respectively have been collected from four different villages of Dharta Watershed of Udaipur district. The analytical results shows higher concentration of TDS 53.33 , EC 45 , and MH 96.67 which indicates signs of deterioration as per WHO and BIS standards. For drinking point of view water quality of the sample investigation reveal that the groundwater is not completely fit for utilization with respect to pH, EC, Na , Mg2 , and Ca2 . In some of the water samples of the area, the concentrations of these elements exceed the acceptable limits of BIS and WHO standards. Katara P. | Maheshwari B. L. | Mittal H. K. | Dashora Y. | Dashora R. | Singh P. K. | Yadav K.

An attempt has been made to develop water quality index (WQI), using Five water quality parameters pH, Nitrates, Chloride, electrical conductivity and fluoride measured at 137 different locations in the study area rating scale is developed based on FAO standards. It was found that 133 samples have the water quality index less than 150 and 4 samples have water quality index between 150-300. By spatial variation of WQI it can be found that 97.08 percent of the water in the area is excellently suitable for irrigation.
Changes in the hydrologic cycle due to increase in greenhouse gases cause variations in intensity, duration, and frequency of precipitation events. Quantifying the potential effects of climate change and adapting to them is one way to reduce urban vulnerability. Since rainfall characteristics are often used to design water structures, reviewing and updating rainfall characteristics (i.e., Intensity–Duration–Frequency (IDF) curves) for future climate scenarios is necessary. The present study regards the evaluation of the IDF curves for Four raingauge stations of Bangalore rural : Anugondanahalli, Devanahally, Doddabalapura and Hoskote. Starting from daily rainfall observed data, to define the IDF curves and the extreme values in a smaller time window (2, 5, 10, 15, 30, 60, 120, 720, 1440 minutes), disaggregation techniques of the collected data have been used, in order to generate a synthetic sequence of rainfall, with statistical properties similar to the recorded data. Then, the rainfall pattern of the Four raingauge stations was analyzed and IDF curves were evaluated
