Kumar, Balmuri Vinay (2014) Determination of infiltration rate of soils using single and double ring infiltrometer and study on drought of karimnagar district of andhra pradesh. BTech thesis.
Infiltration is a process that continuously affects the magnitude and distribution of surface runoff. Field measurement of infiltration is often a tedious task and the infiltration rates can be estimated from the proposed models. Single-ring and Double-rings are used to estimate the infiltration rate of different soils. The main aim of the present study is to find constant infiltration rate of soil. Various infiltration rates obtained during the experiment time are plotted. Results of various infiltration models are compared with the observed data and graphs are drawn for better presentation. The parameters considered for best fitting model were correlation coefficient and standard error. Drought can be considered as strictly meteorological phenomenon. It can be assessed as a meteorological unusual characterized by abnormal moisture deficiency. Drought severity is dependent on the duration and magnitude of the abnormal moisture deficiency. Within the reasonable limits and time the comparison of drought severity is possible. It is assumed that a certain time series model adequately describe the annual rainfall in the region. Based on this assumptions the drought frequency is calculated in the particular region. Calculation of drought is done according to the drought frequency method. There is a software that allows to perform and it is a part of comprehensive computer package. And it was developed early to perform water resources analysis and hydro-meteorological data processing. The procedure of setting up data and running gives a drought estimation and the application was described it in detail.
