SEGURA (anc. Tader), a river of south-eastern Spain about 150 m.
It is formed by the confluence of three head-streams, one of which rises on the northern versant of La Sagra (7875 ft.), a mountain in Granada, while the other two spring from the Sierra de Segura, in Jaen.
Orihuela is situated in a beautiful and exceedingly fertile huerta, or tract of highly cultivated land, at the foot of a limestone bridge, and on both sides of the river Segura, which divides the city into two parts, Roig and San Augusto, and is spanned by two bridges.
The Guayaquil author, Olmedo, who wrote the famous ode on the victory of Junin, and the Limenians Felipe Pardo and Manuel Segura are names well known wherever the Spanish language is spoken.
The comedies of Segura on the customs of Lima society, entitled Un Paseo a Amancaes and La Saya y Manto, have no equal in the dramatic literature of Spanish America and few in that of modern Spain.
Besides many smaller streams, two large rivers water the province, the Segura in the southwest, and the Jucar in the north-east; both rising beyond the borders of Albacete, and ultimately flowing into the Mediterranean.
South of Elche is the province of Murcia, watered by the river Segura, on which there is a dam 25 ft.
Apart from Segura, which flows from the highlands of Albacete through Murcia and Orihuela to the sea, there is no considerable river, but a few rivulets flow east into the Mediterranean.
