Uncertainties on mean areal precipitation: assessment and impact on streamflow simulations
This paper investigates the influence of mean areal rainfall estimation errors on a specific case study: the use of lumped conceptual rainfall-runoff models to simulate the flood hydrographs of three small to medium-sized catchments of the upper Loire river. This area (3200 km2) is densely covered by an operational network of stream and rain gauges. It is frequently exposed to flash floods and ...
متن کاملEstimation of Mean Annual Precipitation in Wyoming Using Geostatistical Analysis
Precipitation is a function of many topographical land features as well as geographical locations. Spatial correlations between precipitation and topographical and geographical features can be used to improve estimation of precipitation distributions. In this study, kriging with external drift of topographical information was utilized for determining precipitation spatial distributions in Wyomi...
متن کاملFunctional Analysis of Iranian Temperature and Precipitation by Using Functional Principal Components Analysis
Extended Abstract. When data are in the form of continuous functions, they may challenge classical methods of data analysis based on arguments in finite dimensional spaces, and therefore need theoretical justification. Infinite dimensionality of spaces that data belong to, leads to major statistical methodologies and new insights for analyzing them, which is called functional data analysis (FDA...
متن کاملSynthesis and characterization of SnO2 nanoparticles by Co-Precipitation method
Tin oxide (SnO2)nanoparticles were synthesized by co-precipitation method and the synthesized nanoparticles were annealed at different temperatures for characterization. The powders were investigated with X-ray diffraction, scanning electron microscopy and optical spectroscopy. The structural characterization was carried out by X-ray diffraction which confirms the crystalline nature ...
متن کاملProbabilistic forecast of daily areal precipitation focusing on extreme events
A dynamical downscaling scheme is usually used to provide a short range flood forecasting system with highresolved precipitation fields. Unfortunately, a single forecast of this scheme has a high uncertainty concerning intensity and location especially during extreme events. Alternatively, statistical downscaling techniques like the analogue method can be used which can supply a probabilistic f...
