Abstract The hay bacillus Bacillus subtilis has attracted scientific interest for more than 100 years due to its ability form heat-stable spores as an example of a rather simple differentiating organism. Thus, this bacterium became one most studied model organisms. Moreover, B. is used in many biotechnological applications and even food production. Current research still adds novel amazing prop...

This paper describes the preliminary development of a network-index approach to modify and to extend the classic TOPMODEL. Application of the basic Beven and Kirkby form of TOPMODEL to high-resolution (2·0 m) laser altimetric data (based upon the UK Environment Agency’s light detection and ranging (LIDAR) system) to a 13·8 km catchment in an upland environment identified many saturated areas th...

This paper describes a new empirical watershed model, the prime feature of which is its parsimony. It involves only three free parameters, a characteristic unparalleled by continuous process models able to work on a wide array of catchments. In spite of its crude simplicity, it achieved, on average, worthwhile results on a set of 140 French catchments and overwhelmingly outperformed a linear mo...

Topographic Effects on Stormflow Acidity David Wolock 1 This paper describes the theoretical and observed effects of topography onstormflow acidity in upland, forested watersheds. The theoretical effects were determined by a sensitivity analysis using the hydrologic model TOPMODEL. The observed effects were determined by an analysis of topographic and stormflow acidity data collected from eight...

A semidistributed, physical-based Urban Forest Effects – Hydrology (UFORE-Hydro) model was created to simulate and study tree effects on urban hydrology and guide management of urban runoff at the catchment scale. The model simulates hydrological processes of precipitation, interception, evaporation, infiltration, and runoff using data inputs of weather, elevation, and land cover along with nin...
