      The tank cascade system (TCS) has been used for over years for water management in Sri Lanka. Since surface water is limited in the dry zone of Sri Lanka, agricultural production, especially of upland crops, relies on groundwater for irrigation. We sampled 29 wells in the Ulagalla cascade, a prominent TCS near Anuradhapura city in the dry zone of Sri Lanka, in Yala (dry) and Maha (wet Cited by: 1. Tank cascade systems in the dry zone are considered as one of the traditional land water management systems and have evolved in order to manage the surface water resources efficiently. Ulagalla cascade is a prominent cascade located in Anuradhapura district with nineteen small tanks and highly utilized for agricultural purposes.

      Rajarata [rā dja ra tə] (Meaning: King's country) (Sinhala: රජරට) (Tamil: ரஜரட) was one of three historical regions of the island of Sri Lanka for about 1, years from the 6th century BCE to the early 13th century CE. Several ancient cities, including Tambapanni, Upatissa Nuwara, Anuradhapura and Polonnaruwa, were established as capitals within the area by successive rulers.   The hydraulic civilisation evolved as a network of streams and tanks in varying sizes spread over the dry zone of Sri Lanka forming tank clusters referred to as tank cascade systems. This cascading form of small tanks and streams was developed to manage the water resource within river sub-basins. These tank cascades are mostly rain-fed but.

        In this system, tanks connected by underground and surface canals form a chain that extends from the foothills to the plains. Once tanks located in the hills are filled to capacity, the water flows down to fill successive tanks, generally ending in a small waterhole. This system conserves about 60 to 70 % of the total runoff in the region! 28 July Dr. C. R.

It is within this framework of the location and hydrography of these cascade meso-basins that meaningful analysis and interpretation of the hydrological endowment and carrying capacity of the approximately 3, functioning small tanks of the, Rajarata could be made.

The small tank systems in these cascades have been rehabilitated from time to time either by the farmers themselves, or government agencies and donor.

Ecological implications of the Tank Cascade Systems The building block of TCSs is a tank (a sub system) which makes up this interwoven irrigation network. Tanks, paddy fields, watersheds and canals are integrated and interwoven with the natural environment (naturalized) (Marambe et al., ) which facilitated the evolution of the TCS over two by: 9.

Since 3rd century BC tank cascade systems in the lowlands within the dry and interme- diate zones of Sri Lanka have evolved in order to efficiently manage the surface water re- sources. A cascade of tanks is made up of 4 to 10 individual small tanks, with each tank having its own micro-catchment, but where all of the tanks are situated within a single meso-catchment basin.

These meso-catchment basins could be varied in extent from 6 to 10with a model value of 8 sq. miles in the North Central Province region.

The North Central Province, although apparently flat, is in reality undulating, and the ancient tank builders took advantage of the nature of the terrain to make strings of tanks in the valleys called the small tank cascade system.
