Ríos

Los ríos de Sri Lanka nacen en las tierras altas centrales. Desde allí descienden a las llanuras y desembocan en el mar. Los ríos suelen ser innavegables en sus tramos superiores, donde fluyen rápida y turbulentamente a través de pasajes altamente erosionados hacia las llanuras inferiores. Muchos ríos descienden por acantilados escarpados, formando cascadas espectaculares. En sus tramos inferiores, los ríos serpentean lentamente a través de llanuras aluviales y deltas.

El río más largo de Sri Lanka, el Mahaweli, recorre un curso de unos 330 km (unas 205 millas). Fluye hacia el noreste a través de las tierras altas centrales y desemboca en la Bahía de Bengala cerca del puerto de Trincomalee, en la costa oriental. El segundo río más largo del país es el Aravi Aru, que recorre unos 220 km (unas 135 millas) en dirección noroeste, desde las tierras altas centrales hasta el Golfo de Mannar.

Sri Lanka no tiene lagos naturales. Las presas en el Mahaweli y otros ríos han creado grandes embalses. Además, una serie de pequeños reservorios, llamados tanques, se extienden por las llanuras del centro-norte, almacenando agua durante la estación seca. Algunos de estos tanques se construyeron hace hasta 2000 años.

Gran parte de Sri Lanka es árida y cuenta con solo unos pocos ríos permanentes. Sin embargo, la "zona húmeda" de la región suroeste se caracteriza por numerosos ríos que nacen en las altas montañas del centro de la isla. Estas diversas cuencas fluviales albergan poblaciones endémicas de plantas acuáticas, bivalvos y peces.

Las especies de agua dulce conocidas de Sri Lanka incluyen 90 peces (con veintiséis endémicas) y 21 cangrejos; sin embargo, estudios en curso sugieren que el número de especies no descritas es potencialmente considerable.
