2009/10/30
Through the rapid development in the field of electrotechniques and the
development ot highly sophisticated recision components it has been possible
to design a new simplified electrical instrumcnt ...
In rural areas the 100-year flood of smaller watersheds has a strong
dependence on the permeability of the geologic subsurface of the watershed
and on the point rainfall intensity.
Based on 70 000 ...
Discharge Measurements by a New-Formed Relative Salt-Dilution Method in Small Turbulent Streams
Discharge Measurements New-Formed Relative Salt-Dilution Method Turbulent Streams
2009/10/28
Water discharges in small turbulent streams are determined by injecting concentrated
salt solutions at constant feed-rate and measuring the dilution level
downstream by conductivity readings in situ...
