Generar un proyecto GUI (con marea) (http://www.mohid.com/wiki/index.php?title=How_to_configure_a_2D_model_forced_with_tide_with_MOHID) Componentes de Marea (Tidal components) Páginas Webs: http://www.mohid.com/forum/viewtopic.php?t=598&highlight=constant+tidal&sid=ee149973a2c8755faa8f8a2cb152f403 Cómo generar una marea? (http://www.mohid.com/wiki/index.php?title=How_to_generate_tide_for_Mohid%3F) Once you created a gridded bathymetry, before you run the model simulation, you may want to generate the tidal gauges that will generate the tide at the open-boundaries during the simulation.

Step 1 - Create the tidal gauges points in the GIS Create a new points layer in GIS

• Make sure that you already have created your bathymetric gridded data file and that it's currently open in your GIS project. Now, simply add a new data item from the menu:

• Select XYZ type, then click on Browse

• Choose a name for the tidal gauge points, then hit save:

• Hit the Ok button

Edit the points layer

• Type 4 in the size text-box, and then select settings:

• Select option Constant, then click on Pick Color (a new window pops up), then select a

bright color and hit Ok on the new window (it will make the new window close), then click on Ok, and the new configuration will be enabled.

• Close and comply with changes by hitting the Ok button

Add the tidal gauges to the points layer

• Select the TideGaugesTest.xyz points layer, then select the add a point command:

• Hit Ok ...

• Click to add points all along the open boundaries, roughly 10 cells wide apart:

• Keep adding those points alternatively on each side of the open-boundary

• Final look:

Save the tidal gauges points layer

• From the Data Items menu, select the Save All option

Step 2 - Generate the tidal gauges from FES2004 In order to generate tidal gauges from FES2004, you will need to obtain the data file and the program that performs the extraction into MOHID tidal-gauge format. Here you will find details about that.

• Get the mohid-tide package and extract it somewhere on your disk;

• Transfer the xyz file to the mohid-tide folder. WARNING: Remove any blank lines from the xyz file!

• Edit the run-tide.bat accordingly to the following example: >mohid-tide ..\fes2004data\tide.nc TideGaugesTest.xyz output.dat 0 2.08

• Run the batch file. This will create the tidal gauge file.

• Verify if your tidal gauge file is correctly formed. Edit it and inspect.

• Descripción General (http://www.mohid.com/forum/viewtopic.php?t=24&highlight=impose+water+level) Para agregar una salida temporal en un punto hay dos maneras de realizarlo:

Una es generando un archivo .dat que contenga la ubicación del punto del que deseo obtener información y además se agrega una linéa al archivo hidrodinámico con la ruta del mismo: TIME_SERIE : 1 DT_OUTPUT_TIME : 600.

TIME_SERIE : 1 <BeginTimeSerie> LOCALIZATION_I : 30 LOCALIZATION_J : 10 LOCALIZATION_K : 1 <EndTimeSerie>

In the data file (see keyword IN_TIDES in the nomfich.dat file) where you defined the tidal guages you can defined the water level associated with a tidal guage in several ways. For example in case of the amplitude evolution (keyword EVOLUTION) you have three options: EVOLUTION : Constant

EVOLUTION : Time Serie EVOLUTION : Harmonics (default option) In your case you want the second option. For this option you need to define the name of the time serie file where you want to defined the water level using the MOHID time series format. TIME_SERIE_FILE : ********* and the column where you defined the water level LEVEL_COLUMN : 2 You have similar options to defined the reference water level REF_EVOLUTION : Constant (defaut option) REF_EVOLUTION : Time Serie For the Time Seire option the time serie file is the same you only need to defined the column REFLEVEL_COLUMN : 3 The water level imposed in the open boundary is always Water level = amplitude + reference level. In the case of Constant option for the amplitude the keyword to define the amplitude is WATER_LEVEL : 1 and to defined the reference level is REF_LEVEL : 2

Overview Lagrangian transport models are very useful to simulate localized processes with sharp gradients (submarine outfalls, sediment erosion due to dredging works, hydrodynamic calibration, oil dispersion, etc.). MOHID’s Lagrangian module uses the concept of lagrangian tracers. The most important property of a tracer is its position (x,y,z). For a physicist a tracer can be a water mass, for a geologist it can be a sediment particle or a group of sediment particles and for a chemist it can be a molecule or a group of molecules. A biologist can spot phytoplankton cells in a tracer (at the bottom of the food chain) as well as a shark (at the top of the food chain), which means that a model of this kind can simulate a wide spectrum of processes. The movement of the tracers can be influenced by the velocity field from the hydrodynamic module, by the wind from the surface module, by the spreading velocity from oil dispersion module and by random velocity. At the present stage the model is able to simulate oil dispersion, water quality processes and sediment transport. To simulate oil dispersion the lagrangian module interacts with the oil dispersion module, to simulate water quality the lagrangian module uses the water quality module. Sediment transport can be associated directly to the tracers using the concept of settling velocity. Another feature of the lagrangian transport model is the ability to calculate residence time. This can be very useful when studying the exchange of water masses in bays or estuaries. Concepts Like referred above, the Lagrangian module uses the concept of tracer. The tracers are characterized by there spatial coordinates, volume and a list of properties (each with a given concentration). The properties can be the same one like the ones described in the water properties module or coliform bacteria. Each tracer has associated a time to perform the random movement. The tracers are “born” at origins. Tracers which belong to the same origin have the same list of properties and use the same parameters for random walk, coliform decay, etc. Origins can differ in the way they emit tracers. There are three different ways to define origins in space:

• a Point Origin emits tracers at a given point; • a Box Origin emits tracers over a given area; • a Accident Origin emit tracers in a circular form around a point;

There are two different ways in which origins can emit tracers in time: • a Continuous Origin emits tracers during a period of time;

• a Instantaneous Origin emits tracers at one instant; • a Moving Origin emits tracers during a period of time along a defined track;

Origins can be grouped together in Groups. Origins which belong to the same group are grouped together in the output file, so it is more easy to analyze the results.

Different alternative methods were coded for the prediction of some processes like oil spreading, evaporation, dispersion, sedimentation and emulsification. Therefore, when using the model, there is more than one way of simulating the same process, depending, for example, on the characteristics of the computational mesh or on the magnitude of the spill. The oil weathering module (OWM) uses mainly the 3D hydrodynamics and 3D lagrangian transport modules. The hydrodynamic module simulates the velocity field necessary for the lagrangian module to calculate oil trajectories. These oil trajectories are computed assuming that oil can be idealized as a large number of particles that independently move in water. Water properties and atmospheric conditions are introduced in lagrangian module and used by oil module for determination of oil processes and properties. Excepting spreading and oil-beaching, all

weathering processes and properties are assumed uniform for all tracers, like water properties and atmospheric conditions, which are considered equal to these environmental conditions determined in accident origin. As it was already mentioned, the movement of the oil tracers can be influenced by the velocity field from the hydrodynamic module, by the wind from the surface module, by the spreading velocity from oil module and by random velocity. Oil temperature is assumed equal to water temperature, neglecting solar radiation or any other energy transfer process that may influence oil temperature.

This is used to compute dispersion and sedimentation. NOTA2: (http://www.mohid.com/forum/viewtopic.php?t=125&highlight=oil) In order to do a simulation with an oil spill you must define atmospheric pressure as a property in ModuleAtmosphere as well as the wind velocity (even if there's no wind or you don't wan't to consider it). You can define these properties like this: <beginproperty> NAME : atmospheric pressure FILE_IN_TIME : NONE INITIALIZATION_METHOD : CONSTANT REMAIN_CONSTANT : 1 DEFAULTVALUE : 1 <endproperty> <beginproperty> NAME : wind velocity X FILE_IN_TIME : NONE INITIALIZATION_METHOD : CONSTANT REMAIN_CONSTANT : 1 DEFAULTVALUE : 0 <endproperty> <beginproperty>

NAME : wind velocity Y FILE_IN_TIME : NONE INITIALIZATION_METHOD : CONSTANT REMAIN_CONSTANT : 1 DEFAULTVALUE : 0 <endproperty> Also, in Lagrangian data file you have keyword BEACHING_LIMIT : 50.0. You will wan't to change this because your grid has a 5m resolution and you're saying that the beaching process is initialized 50m off the coast. 5 or 10 m seems better. With this configuration the model starts to run. But now the problem is that the Hydrodynamic model crashes. You should use the SLOWSTART option (something like 6-12h would be enough) ans also the VISCOSITY_H value is too high. Something like 1m2/s or less would be more appropriate. If you want to simulate Oil dispersion you have to activate module Waves, and define wave height and period. This is used to compute dispersion and sedimentation. I think there are examples on how to do this in the forum or in the sample files.

Module Atmpsphere Wind (http://www.mohid.com/forum/viewtopic.php?t=28&highlight=wind) you have two ways of defining the wind velocity. Option 1 - You can define the wind velocity using as input the wind velocity components X (m/s, west-east) and Y (m/s, south-north); Option 2 - You can define the wind velocity using as input intensity (m/s) and direction (degrees, meteorological convention). In this case you have also to define the properties "wind velocity X" "wind velocity Y" and in each of this two properties you nedd to impose the following options FILE_IN_TIME : NONE REMAIN_CONSTANT : 0 In this case the model will use the wind intensity and the direction to compute the components X and Y of the wind; Option 1 - EXAMPLE: <beginproperty> NAME : wind velocity X UNITS : m/s DESCRIPTION : calculated wind velocity X FILE_IN_TIME : NONE REMAIN_CONSTANT : 1 DEFAULTVALUE : 1. TIME_SERIE : 1 OUTPUT_HDF : 1 <endproperty> <beginproperty> NAME : wind velocity Y UNITS : m/s DESCRIPTION : calculated wind velocity Y FILE_IN_TIME : NONE REMAIN_CONSTANT : 1 DEFAULTVALUE : 0. TIME_SERIE : 1 OUTPUT_HDF : 1 <endproperty> Option 2 - EXAMPLE: <beginproperty> NAME : wind modulos UNITS : m/s DESCRIPTION : meteoIST wind velocity FILE_IN_TIME : NONE DATA_COLUMN : 2 DEFAULTVALUE : 5 REMAIN_CONSTANT : 1 TIME_SERIE : 1
