Emajõgi (; is a river in Estonia which flows from Lake Võrtsjärv through Tartu County into Lake Peipus, crossing the city of Tartu for 10 km. It has a length of 100 km. The name Emajõgi means "Mother River" in Estonian. The Emajõgi is sometimes called the Suur Emajõgi ("Great Emajõgi"), in contrast with the Väike Emajõgi ("Little Emajõgi"), another river which flows into the southern end of Lake Võrtsjärv. Emajõgi is the second largest river in Estonia by discharge and the only fully navigable river. ==Course== The source of Emajõgi is at the northeastern shore of Võrtsjärv at Rannu-Jõesuu, from where the river follows a roughly eastward course towards Lake Peipsi. The course of Emajõgi is divided into 3 distinct sections. In the upper course, from Võrtsjärv to Kärevere bridge, the river flows through large, flat and marshy areas, which are part of Alam-Pedja Nature Reserve. In this heavily meandering section, Emajõgi lacks a clearly defined floodplain – the flooded area spans several kilometres at times and has no definite borders. In the middle course from Kärevere to Kavastu through Tartu, Emajõgi follows a straighter course and flows in a clearly defined, shallow valley mostly a maximum of 10 m deep. The width of the valley in the middle course is 1–1.5 km; in Tartu, it narrows to 800 m. The narrowest section of the valley (400–600 m) is located in the end of the middle course near Kavastu.〔 In the lower course, the river flows through a swampy lowland – Emajõe Suursoo – before emptying into Lake Peipsi at Praaga. The length of the river is . In 1927, its length was measured to be . This may have changed somewhat in the 1930s, when the river's meandering upper course was straightened to allow for easier navigation.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Emajõgi」の詳細全文を読む スポンサード リンク
