Résumé:
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.
