Applying Climate Changes Simulated by GCMs to the Generation of Fine-Scale Rainfall Scenarios

Analysis of Streamflow Changes under Climate Change Using Rainfall-Runoff Model in the Kor River Basin

Abstract In this study, the predicted monthly temperature and rainfall data from HadCM3 model (base period, ۱۹۷۲-۲۰۰۱) and next period (۲۰۱۱-۲۰۴۰) under A2emission scenario were used to investigate the impacts of climate change on runoff variations in the Kor river basin. HadCM3 model output was downscaled based on a temporal downscaling approach (Change Factor) and spatial downscaling appro...

A conditional disaggregation algorithm for generating fine time-scale rainfall data in a warmer climate

Changes to Sub-daily Rainfall Patterns in a Future Climate

This paper describes an algorithm for disaggregating daily rainfall into sub-daily rainfall ‘fragments’ (continuous fine-resolution rainfall sequences whose total depth sums to the daily rainfall amount) under a future, warmer climate. The basis of the algorithm is to re-sample sub-daily fragments from the historical record conditional on the total daily rainfall amount and a range of temperatu...

Simulation of Rainfall - Runoff Events by Applying Phase Differences Diagrams and Correcting Effective Rainfall Components

   The conversion of rainfall to runoff in basins includes nonlinear relations between the complex interactions of various hydrological processes. In this study, without considering of predetermined structure, relationship between input and output system was derived individually from the nature of the data recorded. Also, the phase difference occurred between rainfall and runoff signals using c...

Generation of simulated rainfall data at different time-scales

We desire to generate monthly rainfall totals for a particular location in such a way that the statistics for the simulated data match the statistics for the observed data. We are especially interested in the accumulated rainfall totals over several months. We propose two different ways to construct a joint rainfall probability distribution that matches the observed grade correlation coefficien...
