Evaluating the snow component of a flood forecasting model
The objective of this study is to evaluate the snow routine of a semi-distributed conceptual water balance model calibrated to streamflow data alone. The model is used for operational flood forecasting in 57 catchments in Austria and southern Germany with elevations ranging 200–3,800 m a.s.l. We compared snow water equivalents (SWE) simulated by the hydrologic model with snow covered area (SCA) derived from a combined product of MODIS (version 5) Terra and Aqua satellite data for the period 2003–2009...
Flood Forecasting and Warning Services in general
An exact and early Flood Forecasting allows accordant early warning of persons concerned as much as the establishment of necessary measures (see Flood Protection, Evacuation and Rescue Plans). Therefore, it can make an important contribution to avoid damage. Flood Forecasting is in most cases based on extensive numerical modelling which is created with hydrological and hydraulic models of different complexities. Depending on the local situation and available database, different input data was used e.g.: data...
Comparison of digital and manual methods of snow particle size estimation
Maintaining long time series of observations of the Cryosphere is a key issue in climate research. Long observational time series involve problems due to change in methodology or observers. In order to extend time series and introduce new methods, careful comparisons must be made to ensure homogeneity in the observational data. We have compared an established method for snow grain-size observations used by the Abisko Scientific Research Station (ASRS) in northern Sweden, based on visual interpretation, with a...
Developing a typical rainfall period to analyze CSOs in San Francisco
The City of San Francisco has used InfoWorks CS as the basis for developing a continuous long-term (five year) rainfall period, which is being used to evaluate sewer flows in a collection system model. Ultimately, the City aims to develop a 30-year plan for its combined sewer and wastewater treatment system, a major cornerstone of which is the creation and application of a detailed hydraulic model of the sewer system. This will evaluate the effect of various alternatives on sewer system flows, as well as CSO...
Response of the Indian summer monsoon circulation and rainfall to seasonal snow depth anomaly over ...
Several observational and modeling studies indicate that the Indian summer monsoon rainfall (ISMR) is inversely related to the Eurasian snow extent and depth. The other two important surface boundary conditions which influence the ISMR are the Pacific sea surface temperature (SST) to a large extent and the Indian Ocean SST to some extent. In the present study, observed Soviet snow depth data and Indian rainfall data for the period 1951–1994 have been statistically analyzed and results show that 57% of heavy snow...
Bacterial communities associated with the rhizosphere of transgenic Bt 176 maize (Zea mays) and its ...
The effect of transgenic Bt 176 maize on the rhizosphere bacterial community has been studied with a polyphasic approach by comparing the rhizosphere of Bt maize cultivated in greenhouse with that of its non transgenic counterpart grown in the same conditions. In the two plants the bacterial counts of the copiotrophic, oligotrophic and sporeforming bacteria, and the community level catabolic profiling, showed no significant differences, differences between the rhizosphere and bulk soil bacterial communities were...
Rainfall, Runoff and Infiltration Re-visited
Introduction The flow variations in sewers have been modelled for several years with a comparatively high degree of accuracy as far as the diurnal variations and responses to climatic conditions are concerned. However, until comparatively recently the variations in flow due to fluctuations in groundwater levels, soil storage capacity and wetness of the catchment have only been modelled in basic terms. For the past decade it has been possible to use runoff models that respond to the increasing wetness of the...
Enhancement of Terrestrial Carbon Sink Potential: A Possible Contribution to Mitigating Global ...
Introduction Climate researcher Klaus Hasselmann, Director of the Max-Planck-Institut (MPI) for Meteorology in Hamburg and a project co-ordinator of EC’s Environment and Climate Programme, was one of the first scientists to warn that recently observed global warming trends have a discernible human related forcing component. Climate model calculations show, that global warming is closely related to rising atmospheric concentrations of greenhouse gases (GHGs) as consequence of man’s activity. Since pre-industrial...
