A method to disaggregate daily rainfall into hourly precipitation is evaluated across Texas. Based on measured precipitation data, the method generates disaggregated hourly hyetographs that match measured daily totals by selecting storm intensity patterns from measured hourly databases using a one parameter selection method. The model is applied across Texas using historic data measured at hourly precipitation gauges; performance is evaluated by the model's ability to reproduce the measured… 

Assessing methods to disaggregate daily precipitation for hydrological simulation

As researchers explore the impacts of climate change on water resources, they often will use downscaled data from General Circulation Models (GCMs). While such output provides our best estimates of

Temporal disaggregation of hourly precipitation under changing climate over the Southeast United States

Climate change impacts on precipitation characteristics will alter the hydrologic characteristics, such as peak flows, time to peak, and erosion potential of watersheds. However, many of the

Usability of the BLRP model for hydrological applications in arid and semi-arid regions with limited precipitation data

In this study, Hydrological Simulation Program-FORTRAN (HSPF) is used to investigate rainfall-runoff process in Taleghan watershed, northern Iran. Despite the high accuracy of the model, the lack of

A method to identify and track rainfall structures using 1-h accumulated NEXt generation RADar (NEXRAD) rainfall data is presented and used to analyze the dynamics of storm features over an area in

Effects and consideration of storm movement in rainfall–runoff modelling at the basin scale

Abstract. A number of studies have emphasized the effects of rainfall movement on runoff simulation; nevertheless, due to the lack of rain gauges inside sub-basins, a method using a hyetograph of the
