Performance high-resolution X-band radar rainfall measurement Netherlands
2010/2/20
This study presents an analysis of 195 rainfall events gathered with the X-band weather radar SOLIDAR and a tipping bucket rain gauge network near Delft, The Netherlands, between May 1993 and April 19...
DEPTH INTERVALS AND TOPSOIL MOISTURE MEASUREMENT WITH THE NEUTRON DEPTH PROBE
DEPTH INTERVALS TOPSOIL MOISTURE MEASUREMENT NEUTRON DEPTH PROBE
2009/10/29
From measurements and calculations using a depth probe, the relative
response is estimated for soil layers of different thicknesses. For a 10 cm
thick layer of soil with the instrument centre in the...
Measurement and Mapping of Potential Evapotranspiration in a Small Mountainous Watershed
Measurement Mapping Potential Evapotranspiration Small Mountainous Watershed
2009/10/28
The potential evapotranspiration ETP can be estimated by using Brochet and
Gerbier's formula (1972), which is derived from Penman's equation
where m and n are tabulated coefficients depending on sea...

Measurement Modeling of Microwave Emission Forested Snowfields
2009/10/28
Forest cover was found to confuse the normally inverse relationship between
microwave brightness temperature (TrJ) and snow depth in dry snowpacks in
the lower peninsula of Michigan during February ...

A dynamic rating curve approach to indirect discharge measurement
dynamic rating curve steady-flow indirect discharge measurement
2009/7/22
The operational measurement of discharge in medium and large rivers is mostly based on indirect approaches by converting water stages into discharge on the basis of steady-flow rating curves. Unfortu...
