Abstract
Abstract. Hydrological studies in experimental and representative basins are of fundamental importance for water resources management. This paper presents some activities of hydrological research in experimental and representative basins of the State of Pernambuco, Brazil. The study areas are located at Tapacurá and Mundaú representative basins and at the Gameleira experimental basin, and in experimental plots in Pajeú basin. In the Tapacurá basin, three studies were performed: (1) different monthly coefficients "k" of the Thornthwaite method were tested to calculate the effective temperature and, consequently, the reference evapotranspiration, giving rise to the method identified as Modified Thornthwaite; (2) the spatial variability of the retention curve and hydraulic conductivity parameters were analysed using the Beerkan method; (3) changes in vegetation cover were evaluated through the NDVI and NDWI indexes using TM–Landsat 5 images. In the Mundaú representative basin, the performance of different evapotranspiration methods was evaluated and compared to the FAO standard method, Penman-Monteith. In the Pajeú basin, the experimental plot is covered by pasture and sensors were installed to monitor the following variables: rainfall, air temperature, the energy balance components (net radiation, latent and sensible heat, and soil heat flux), wind velocity and CO2 flux into atmosphere, soil moisture and runoff.
Highlights
A fundamental aspect for adequate water resources management is the knowledge of hydrological quantities like evapotranspiration, hydraulic conductivity, etc
In the State of Pernambuco, Brazil, the poorest state in terms of water availability, scientific research related to water resources has been conducted in Tapacurá, Mundaú and Pajeú basins
It is of great importance to study the hydrological processes that occur in these basins, because these basins are representative in Pernambuco State and are located in areas of water scarcity, mainly in Mandau and Pajeú basins
Summary
A fundamental aspect for adequate water resources management is the knowledge of hydrological quantities like evapotranspiration, hydraulic conductivity, etc. In the State of Pernambuco, Brazil, the poorest state in terms of water availability, scientific research related to water resources has been conducted in Tapacurá, Mundaú and Pajeú basins. These studies were led by UFPE (Federal University of Pernambuco) and UFRPE (Federal Rural University of Pernambuco). It is of great importance to study the hydrological processes that occur in these basins, because these basins are representative in Pernambuco State and are located in areas of water scarcity, mainly in Mandau and Pajeú basins. Within the Tapacurá representative basin is the Gameleira experimental basin, where several studies are conducted in the context of hydrology
