Overview
Module Discharges handles all the point discharges in Mohid Water Modelling System. These discharges can be simple water discharges but can also have properties such as substances concentration (temperature, salinity, nutrients, contaminants, etc) and/or momentum.

MOHID WATER
Here's what a configuration file of the Module Discharges should look like for a single river run-off. Note that you are previously required to build a time serie .srw with the flow, the temperature and the salinity in order to correctly implement the discharge.

MOHID RIVER NETWORK
For Mohid River Network discharges can be made on nodes. As so, you will need to check within the drainage network difinition in which node to discharge. Here's what a configuration file should look like for a single discharge. Note that you are previously required to build a time serie with the flow, and any other property in order to correctly implement the discharge.
Discharges into MOHID River Network can be automatically linked to SWAT model discharges; see description in SWATLink download package in www.mohid.com
Steps after creating the discharge time serie (with time and flow as minimum):
1 - Have to activate module discharges so that Discharges_X.dat in input data file appears in the simulation (in Simulation Properties add the model if not present)
2 - The block <begindischarge> <enddischarge> has to appear in Discharges_X.dat and can add the number of discharge properties that you want (or none, if only water discharged)
<begindischarge> NAME : NODE_19 DESCRIPTION : Not given NODE_ID : 19 DATA_BASE_FILE : ..\..\GeneralData\Discharge.dat FLOW_COLUMN : 2 <<beginproperty>> NAME : nitrate UNITS : mg N/l DESCRIPTION : nitrate TIME_SERIE_COLUMN : 3 <<endproperty>> ... <enddischarge>
3 - have to activate discharges (DISCHARGES : 1) in DrainageNetwork_X.dat
4 - run the simulation and compare flow results in HDF or in node timeseries between a simulation with the discharge and without it (the discharge will only appear in the node timeseries results that are downstream of the inputed discharge).
