Usos da Água e Desperdício no perímetro irrigado do Açude de Lagoa do Arroz - PB.

Abstract

The present work aims to discuss the waste water uses of the Lagoa reservoir. of Rice which must be attributed mainly due to the lack of awareness of the population and irrigating farmers, who are the main users who use water from the said reservoir in an unbridled manner and as a result of these acts cause huge waste, as should also be taken into account the negligence of organs responsible for managing and monitoring the floodgates. The search has how main approach to assess the main forms of water use in the next irrigation causing the greatest waste of water from the Lagoa do Arroz Dam. To do so, they were the following methodological procedures were adopted: bibliographic survey, research documentary and field research. It brings a brief history of the construction of dams for being a viable alternative to minimize the effects of large water shortages in the semiarid region Northeast, multiple uses such as ebb system, fishing activity, supply of the cities of Santa Helena and Bom Jesus, irrigation and leisure and the disordered uses and the water waste generated from five specific points the lack of monitoring of the Açude floodgates, branches on private land, various water catchment points, opening of the gate from the main channel to the secondary ones carried out by themselves farmers and finally inefficient irrigation systems. A description about features physics of the area surrounding the weir and finally the analysis and interpretation of data.
