Dali (or Dhali; Greek: Δάλι; Turkish: Dali) is a town in Cyprus, located in the South Nicosia area about 20 km (12 mi) south of central Nicosia and is at an altitude of 220 m (720 ft). It is the largest settlement amongst a group of villages in the area which are connected to Dali by a radial road network. The dominant element of this area around Dali is the Yialias River, on which the people were dependent in former times.
Dali is built close to the Yialias riverbed, on its southern side. Further north, the municipal area is dissected by the Alikos, a tributary of the Yialias, where the Dali industrial zone is sited. This consists of many light industrial units.
The Alikos or Alykos (Greek: Αλυκός or Greek: Άλυκος, Turkish: Alikos) is a river in Nicosia District, Cyprus, a tributary of the Yialias. The river originates in the Machairas Forest in the Troodos Mountains close to Kapedes and flows northeast across the Mesaoria plain, to Ayios Sozomenos, south east of Nicosia, where is joins the Yialias.
The Alikos is only an intermittently flowing river. Near its source the average rainfall is around 52.5 cm (20.7 in) per annum.
