This depends on the type of station you want to report from: a weather station, a water station, the Weather@Home or the Photo Note. Look at the instructions for every station type below:

1.) Are you at the weather station?

Take a photo of the info board. Make sure that it is possible to read the values on the thermometer, hygrometer and the rain gauge from the photo (see example below).

 - here the sample image should be placed -

2.) Are you at the water station?

Take a photo of the water level gauge in the water (see example below) and make sure that it is possible to read the value of the water level gauge from the photo. Note that the water level gauge at your station could look slightly different than in the example.

 - here the sample image should be placed -

3.) Do you want to report from your Weather@Home station?

Take a photo of your rain gauge (see example below) and make sure that it is possible to read the value easily.

 - here the sample image should be placed -

4.) Do you want to report a photo note?

These can be used to share photos of any kind of weather events, for example a hail storm, a flooding or a dry river bed. Here are some examples:

 - here the sample image of the flood should be placed -

On the picture above you can see a flooded river.

 - here the sample image pf the dry river should be placed -

On the picture above you can see a nearly dried out river.

- here the sample image of the soil erosion should be placed -  

On the picture above you can see heavy soil erosion (the rain has partially washed away the soil).

- here the sample image of the drought should be placed -

On the picture above you can see a drought.

Turbidity can be measured with a turbidity tube (see image below).- here the first sample image should be placed -

The tube has a scale on the side. Higher values indicate that more particles are dissolved in the water and that it its less clear. In terms of water quality, the lower the value the better.

To measure the turbidity several steps are necessary:

First fill the bucket attached to the chain with water from the river. Try to collect water from the surface of the river and not from the river bed.

Then pour a little bit of water into the turbidity tube until it reaches the first mark (see sample photo below).

- here the second sample image should be placed -

Now look into the turbidity tube from the top. Can you see the green circle at the bottom of the tube?

- here the third sample image should be placed -

If you can't see the green circle anymore, read the value at the lowest mark on the tube and enter the value in the appropriate field in the HydroCrowd app. If the green circle is still visible, fill the tube until the next mark. Repeat the process until you can't see the green circle anymore.

- here the fourth sample image should be placed -

Enter the value in the application where the circle is no longer visible.

La turbidez puede medirse con un tubo de turbidez (vea la siguiente imagen).

El tubo tiene una escala en un lado. Los valores más altos indican que hay más partículas disueltas en el agua y que es menos clara. En términos de calidad del agua, cuanto menor sea el valor, mejor.

Para medir la turbidez son necesarios varios pasos:

En primer lugar, llena el cubo fijado a la cadena con agua del río. Intenta recoger agua de la superficie del río y no del fondo.

A continuación, vierta un poco de agua en el tubo de turbidez hasta que alcance la primera marca (vea la foto de ejemplo abajo).

- here the second sample image should be placed -

Ahora mira dentro del tubo de turbidez desde arriba. Puedes ver el círculo verde en el fondo del tubo?

Si ya no puedes ver el círculo verde, lee el valor en la marca más baja del tubo e introduce el valor en el campo correspondiente de la app HydroCrowd. Si el círculo verde sigue visible, llena el tubo hasta la siguiente marca. Repite el proceso hasta que ya no puedas ver el círculo verde.

- here the fourth sample image should be placed -

Introduzca el valor en la aplicación cuándo el círculo ya no es visible.

A water level gauge can be used to measure the water level in a river. By taking regular measurements, you can record the changes in water level over time. The scale on the water level gauge is in centimeters (cm). Note that there are different types of water level gauges which differ slightly in their numbering (see the example below):

- here the comparison sketch of the water level gauges should be placed -

One type of water level gauge you can see on the below:

- here the sample image of the water level gauge should be placed -

The values 60 to 90 cm and a red "1" on top are visible. The red one represents 100 cm or 1 meter. On this example the water level gauge             indicates a value of 56 which means the current water level is 56 cm.

In the case that the water level of a river regulary rises above 100 cm there can be several similar water level gauges mounted on top or diagonally above each other (see example below). Then the number on top will give you information how high the level is, when the other             water level gauges are underwater.

- here the sample image of the water level gauges should be placed -

For example, if the water level is at the middle of the water level gauge with the red 4 the current water level will be 350 cm.

Una regleta puede utilizarse para medir el nivel del agua en un río. Realizando mediciones periódicas, puedes registrar los cambios del nivel del agua a lo largo del tiempo. La escala del indicador del nivel del agua está en centímetros (cm). Ten en cuenta que existen diferentes tipos de indicadores del nivel del agua que difieren ligeramente en su numeración (véase el ejemplo siguiente):

- here the comparison sketch of the water level gauges should be placed -

Un tipo de regleta se puede ver a continuación:

- here the sample image of the water level gauge should be placed -

Se ven los valores de 60 a 90 cm y un "1" rojo en la parte superior. El "1" rojo representa 100 cm o 1 metro. En este ejemplo, al regleta indica un valor de 56, lo que significa que el nivel de agua actual es de 56 cm.

En el caso de que el nivel del agua de un río suba regularmente por encima de 100 cm, pueden haber varias regletas similares montadas una encima de la otra o en diagonal (véase el ejemplo siguiente). Así, el número situado en la parte superior le informará de la altura del nivel cuando las demás regletas esten sumergidas.

- here the sample image of the water level gauges should be placed -

Por ejemplo, si el nivel del agua se encuentra en el centro del indicador de nivel de agua con el 4 rojo, el nivel actual del agua será de 350 cm.

Rainfall at a certain location is measured with a rain gauge. At the station, the rain gauge is mounted on the right side of the info board (see example below).

   - here the sample image of the info board should be placed -

Rainfall is measured in millimeters (mm). The scale on the side of the rain gauge indicates how much rain fell since the last time the rain gauge was emptied. The scale is divided in intervals of 1 mm (short marks) and 5 mm (long marks). Look at the water in the rain gauge. Position yourself, such that your eyes are at the same height as the water level in the rain gauge (see example below).

   - here the sample image of the rain gauge should be placed -

The mark closest to the water level in the rain gauge is the amount of rainfall. In the example above the rainfall is 23 mm. After submitting your rainfall measurement, don't forget to empty the rain gauge by turning it upside down and afterwards turning it back with the inlet facing torwards the sky (like it is on the first image).

The thermometer measures the air temperature at a certain location. The thermometer at this station measures temperatures from -35 to 55 degrees Celsius (°C) (see example below).

   - here the sample image of the thermometer should be placed -

When the temperature is negative (below 0°) it is freezing. The scale on the thermometer is divided into intervals of 1°C (short marks) and 5°C (long marks). The mark closest to the pointer is the current temperature. In the example above the temperature is 17,5 °C.

The hygrometer (see example below) measures how moist the air is at a certain location. This is also called relative humidity.

   - here the sample image of the hygrometer should be placed -

It can measure the humudity from 0 % (completly dry) to 100% (very humid). The scale on the hygrometer is divided into intervals of 1% (short marks) and 5% (long marks). The mark closest to the pointer is the current humidity. In the example above the humidity is about 50%.
