WRM web version: Control nodes
A WRM scenario can include any number of control nodes.
Control nodes report the observed flow or any deviation of the observed flow at a given
location against prespecified target flow values.
Several types are available:
 control,passive
 control,MINtarget
 control,MAXtarget
 control,combined
 control,calibration
which differ in their data requirements and the reports they generate.
Data sets
NODE NAME 
short but descriptive display name for the node 
type  types include: passive,MINtarget, MAXtarget, combined, calibration 
Object_link 
optional link to a river basin OBJECT of type: flow monitoring station 
MINtarget_TS 
time series of mimimum flow requirements 
MINtarget_mult 
multiplier for time series of mimimum flow requirements 
MAXtarget_TS 
time series of maximum allowable flow 
MAXtarget_mult 
multiplier for time series of maximum flow 
reference_TS 
time series of reference of calibration flow 
reliability threshold  defines the minimum amount on a daily basis (e.g., 90%)
to consider the demand met. Default: 100%

Dynamic Output Time Series:
A control node generates the following output time series,
depending on the data sets provided:
 throughflow;
 shortfall MIN(0,observedflow  MINtarget);
 excess MAX(0,observedflow  MAXtarget);
 deviation (observedflowreference_flow)
In addition, summaries are calculated for shortfall and excess
(average and total); for deviation the statistics reported are:
 BIAS (difference of means)
 RMSE (root mean square error)
 correlation (covariance)
 frequencies (%) of daily violations (reliability, excess)
control,passive
 Input: none;
 Output: throughflowTS
control,MINtarget
 Input: MINtargetTS and multiplier, reliability threshold;
 Output: throughflow(TS), target(TS), shortfall(TS), reliability (% days where the target is met
with a threshold of % volume) on a daily basis).
control,MAXtarget
 Input: MAXtargetTS, multiplier, exceedance threshold;
 Output: throughflow(TS), target(TS), excess(TS), exceedance%.
control,combined
 Input: both MINtargetTS and multiplier, MAXtargetTS and multiplier, thresholds;
 Output: throughflow(TS), both targets(TS),
shortfall(TS), reliability; excess(TS), exceedance%.
control,calibration
 Input: reference_TS, multiplier (default: 1.0);
 Output: throughflow(TS), reference_TS, deviation(TS);
BIAS (difference of means), RMSE (root mean square error), correlation (covariance).
