1. The design and evaluation of travelling gun irrigation systems: enrolador software
ABSTRACT Travelling gun irrigation systems offer great mobility and operation flexibility with a low investment cost per unit of irrigated area. However, the drawbacks include high operating pressure, low application efficiency, and high rainfall, runoff and erosion. Many of these problems can be minimized if the design and operation of travelling gun irriga

2. COMPARAÇÃO ENTRE DOIS SISTEMAS HIDRÁULICOS DE MEDIÇÃO DE AGUA DE IRRIGAÇÃO DE ARROZ / COMPARISON BETWEEN TWO HIDRAULICS SYSTEMS OF MEASUREMENT OF RICE IRRIGATION WATER
The irrigated farm crops are the main users of water. With this, in places where there is a water shortage to attend all sorts of use, this kind of activity is characterized like as a potentially conflicting, once that to produce one hectare of rice, are necessary thousands cubic meters of water. To work out this conflict, many actions are been developed, as

4. Characterization, treatment and reuse of greywater and rainwater use in buildings. / Caracterização, tratamento e reúso de águas cinzas e aproveitamento de águas pluviais em edificações.
The reuse of greywater and the rainwater catchment for non potable uses meets the premises of sustainability and the concept of water conservation. Properly conceived greywater reuse systems and rainwater catchment systems should follow four basic criteria: hygienic reliability, aesthetics, environmental protection and technical/economic feasibility. The gre

5. Simulating the use of the agricultural sector water in the Jundiá creek basin / Simulação do uso da água do setor agrícola na bacia do Córrego Jundiá
In the past, the occurrence of the territorial occupation in Brazil was extremely disordered and the inadequate use of the natural resources caused serious negative impacts on the water resources, such as the deterioration of the water and the consequent reduction in the water availability. Nowadays, there are few tools that allow the users and management ag

7. Sistemas de irrigação e manejo de água na produção de sementes / Irrigation systems and water management for seed production
High quality seed production, in na economically feasible way, demands for appropriate use of the available production technologies, like irrigation, wich is often considered as a guaranteed way to improve and ensure yield. However, many factors contribute for not reaching the full economic results this technique allows for. Among these factors are inadequat
