# 3.10.3. Rules for adding attributes to rivers

Rivers in Yandex Map Editor are [composite linear items](https://www.yandex.com/support/mapeditor/en/line2.md#line2) that are not drawn on the map, but are compiled from sections of riverbed, each of which is drawn individually and assigned separate attributes. For more information, see [3.10.2. The rules of attribution of hydrographic objects](https://www.yandex.com/support/mapeditor/en/cat_hydr_rul2.md#cat_hydr_rul2)).

Rivers are created as individual items when you fill in the **Part of** attribute panel for the riverbed section (for more information, see section [3.10.2.2.1](https://www.yandex.com/support/mapeditor/en/cat_hydr_rul2.md#3.10.2.2.1)). After you create the river, its name will appear as a link in the attribute panel for that section of riverbed.

The river's attribute panel will open when you click on the link:

Click ![](_assets/btn_03.png) (**Edit**) to switch the panel to editing mode:

Use the panel to add attributes to the river.

Techniques for adding attributes to rivers are similar to the [techniques for adding attributes](https://www.yandex.com/support/mapeditor/en/attr.md#attr) to all items on YME.

The attributes for **River** items are listed below, as well as the rules for entering values for each of them:

- [3.10.3.1. Type of river](#3.10.3.1)
- [3.10.3.2. Name of river](#3.10.3.2)

## 3.10.3.1. Type of river {#3.10.3.1}

**3.10.3.1.1** {#3.10.3.1.1}

 
:   Select the river type from the list in the **Type** field:
    
    
    
    - **Major river** — a river that is at least 1,000 km long.
    - **Large river** — a river between 400-500 km in length.
    - **Middle-size river** — a river that is at least 20 km in length, but not longer than 400-500 km. This category also includes named streams and channels regardless of their length.
    - **Small river** — unnamed rivers, named rivers less than 20 km long, and un-named streams.
    - **Stream** — named streams.
    - **Intermittent river** — all rivers that are drying up, regardless of their length.
    - **Channel** — named channels (other than those that are labeled as major or large rivers as exceptions to the rule).
    - **Drainage channel** — irrigation and drainage canals, as well as drainage ditches (including those located along roads).

**3.10.3.1.2. Connectivity of river systems** {#3.10.3.1.2}

 
:   When selecting a river type, you must preserve how the river system is **connected**: each class of river should connect to rivers of higher types to form a united (connected) system within the boundaries of that river basin.

**3.10.3.1.3. Hierarchy of river systems** {#3.10.3.1.3}

 
:   When selecting a river type, you must preserve the **hierarchy** the river system. For example, a given river can not be tributary to a lower type of river. For example, a large river can not be a tributary to a small- or medium-sized river.
    
    
    
    Therefore, a river that relates to a lower type than its tributary based on its physical characteristics will be assigned a higher type equal to that of as the tributary.
    
    
    
    When selecting a river type, account for its entire length, ignoring splits at state borders.
    
    
    
    Rivers that connect channels should have a type no lower than <q>Middle-size river</q>.

## 3.10.3.2. Name of river {#3.10.3.2}

Enter the name of a river in the **Part of** field of the attribute panel for that **section of riverbed** (this is partially shown in the drawing): As you start entering the name of the river into the field, a list of suggestions comprised of rivers that are already on the map will appear automatically:

![](_assets/hy_06.png)

If the river is not on the map yet, you must fill in this field manually: enter a name for the new river and it will be created.

The techniques for entering river names are similar to the [techniques for entering names](https://www.yandex.com/support/mapeditor/en/attr_name.md#attr_name) for all items on YME.

When you duplicate a riverbed or channel using a polygon, assign **Body of water** attributes to that item. Don't name the following polygonal items: the **Name** field should be left blank (see [3.10.2.1.3. Duplication of a river or channel by a contour](https://www.yandex.com/support/mapeditor/en/cat_hydr_rul2.md#3.10.2.1.3)).

If a waterway or a body of water is located within a terrain item, do not set the name of that terrain item (gulch, ravine, ditch, and so on) as the waterway name, unless that item is labeled as a <q>quarry</q>.

**3.10.3.2.1. Rules for naming rivers** {#10.3.2.1}

 
:   When naming rivers, follow the rules specified in Section [3.1.3. Map item naming rules](https://www.yandex.com/support/mapeditor/en/attr_name.md#attr_name).
