The rivers of Ecuador are an important part of the nation's geography and economy. Most of the over 2,000 rivers and streams〔Terry〕 have headwaters in the Andes mountain range, flowing therefrom either westward toward the Pacific Ocean or eastward toward the Amazon River.〔Hanratty〕 Narrow in the highlands, the majority of the rivers broaden as they reach the lower elevations of the Coast and Oriente.〔 During the rainy season, which lasts from January to April, the rivers that drain into the Pacific flood and often cause damage. ==Geography== The two main water systems are the Esmeraldas River in the North and the Guayas in the South.〔Gerlach〕 The Esmeraldas begins as the Guayllabamba River in the Sierra, flowing west before emptying in the Pacific near the city of Esmeraldas. The Guayas forms to the north of Guayaquil, where the Daule and the Babahoyo Rivers converge. The Babahayo arises from its tributaries in the Andes. The Guayas basin covers 40,000 square kilometers.〔 The most important rivers in the Oriente are the Pastaza, Napo, and Putumayo. The Pastaza includes the Agoyan Waterfall, Ecuador's highest. 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「List of rivers of Ecuador」の詳細全文を読む スポンサード リンク
