(Redirected from Segura River)
'Segura' (Latin ''Thader'', Arabic ''War-Alabiat'', Spanish and Catalan ''Segura'') is a medium-sized river in southeastern Spain.
It starts at Santiago Pontones (province of Jaén), passes Calasparra, Cieza, Murcia, Beniaján, Orihuela, Rojales and ends in the Mediterranean Sea near Guardamar del Segura in the province of Alicante. Some of its tributaries are the Mundo (which starts near Riópar), the Alhárabe (which starts in Moratalla), the Mula and the Guadalentín.
The Segura is usually in a state of semi-permanent drought, however, now and then, it does occasionally flood as the consequence of the torrential rains which typically take place once every 6-9 years approximately, always in Autumn.
In the twentieth century significant flooding occurred in 1946, 1948, 1973, 1982, 1987 and 1989. Since 1990 the lower reaches of the river have been canalized, removing meanders and hence improving the evacuation of flood waters. The new canal was put to the test in September of 1997 and October of 2000 when heavy rainfall resulted in significant runoff.
The alluvial plain is called the ''Vega del Segura'' and is a very productive agricultural region growing a wide variety of fruit, vegetables and flowers. The ''Vegas'' are divided into three areas: ''Alta'', ''Media'' and ''Baja'' (upper, medium, and lower).
The Segura was one of the most polluted rivers in Europe. However, in recent years extensive water management techniques and the implementation of waste water treatment plants have greatly improved the situation. What must be considered is that the mean discharge is around 2 to 3 m³/s in Murcia city making it very difficult to dilute illegal pollutants.
