Abstract: the recession coefficient (α) indicates the production rate of the baseflow, that represents the part of the river flow which is predominately maintained by groundwater restitution. it can be obtained through hydrographic analysis. this coefficient allows the calculation of important parameters, such as aquifer transmissivity, renewable groundwater reserves, and low flow in drainage channels that usually are obtained through other hydrological indexes, such as the q7,10, frequently used in the management of surfi cial hydrological resources. the studied basins are located in the central-southern region of the minas gerais state, in areas of granite-gneissic rocks, with similar vegetation, climate and landuse. the results were satisfactory, showing that the determination methods for the recession coefficients may be used to characterize groundwater production in the hydrographic basins of the crystalline basement. the groundwater discharged into the drainage systems is greater in areas with smoother relief, indicating that they constitute the best recharge areas.

Abstract: The aim of this article is to discuss the theoretical issues behind reading processes, the relationbetween this skill and dyslexia, and to present some results from a pseudowords reading test with Portuguesechildren. Developmental dyslexia is a specific learning disability characterized by difficulty inlearning to read, and there is strong evidence that dyslexia is related to underlying deficiencies in phonologicalskills. Phonological deficits establish robust differences between dyslexic and normal readers and,according to the theoretical background, phonological awareness can be assessed with pseudowords tests.In this study, we applied the Pseudo words Reading Test, one of twenty tests of the Battery of Tests toAssess Developmental Dyslexia (BADD) constructed to assess dyslexia in Portuguese children between 7and 12 years old. We gave the Pseudo words Reading Test to 555 Portuguese children, aged 8 to 12.Fifty-seven of these children had been previously assessed by other professionals as dyslexics. We triedto verify how factors like age, gender and learning disabilities influence the acuity in pseudo words readingand if this test can be used to assist in an early diagnosis of developmental dyslexia. The results provethat there are significant differences between dyslexic children and normal readers in reading pseudowords in Portuguese language.
