The rainfall runoff model is one of the most frequently used events in hydrology. It determines the runoff signal which leaves the watershed from the rainfall signal received by the basin. The present study develops an distributed approach to simulate the rainfall runoff process of a catchment. The catchment area has been divided in to the numbers of divisions equal to the numbers of rain gauge station. An lump model is also developed using average rainfall of the catchment. In case of lump model, average rainfall is calculated using thessian polygon method. In order to estimate runoff from...

This book focuses on examining the martingale and long memory characteristics of the Indian exchange rates relative to US Dollar, Great Britain Pound (GBP), Euro and Japanese Yen. However, the analysis can be extended to any financial time series. This book also reviews the various methods to study the martingale property and long memory property of the financial time series. This book can be helpful to research scholars who want to pursue research in this area.
