Discharge has been measured at three locations. at these locations, measurement weirs have been installed in may 2007 to estimate discharges accurately. a v-notch weir is used to measure the inflow of surface water into the catchment near the wielse kade (qin). trapezoidal rossum weirs have been installed to measure outflow (qout1 and qout2), of which the stage-discharge relations have been obtain…

Groundwater levels at cabauw have been measured since august 2003 in two fields south of the tower. nine piezometers were placed in a row. initially, 6 of those piezometers contained pressure transducers (of the brand keller) to measure levels automatically every 4 hours. on 9 july 2010, the temporal resolution was increased to hourly. several sensors have stopped working since 2003. piezometers t…

Degree days are determined by the effective daily mean temperature (teff). teff is calculated with the daily mean temperature (tg) and the daily mean windspeed (fg). teff = tg - 2/3 * fg. degree days = sum of the days with (max[(14 - teff),0]).
