1. Estudo morfológico e hidroquímico de pequenas depressões na Nhecolândia, Pantanal, MS / Morphological and hydrochemical study of small depressions in Nhecolândia, Pantanal, MS
The southern part of the Taquari alluvial fan, called Nhecolândia, is a sub-region of the Pantanal of Mato-Grosso exhibiting a complex of round shape lakes, draining fields, forested sandy areas, small watercourses and small depressions. Former studies have shown that the sub-superficial water fluxes depend on the intensity of the flood and on the presence

2. The burrows of Parastacus defossus (Decapoda: Parastacidae), a fossorial freshwater crayfish from southern Brazil
Parastacus defossus Faxon, 1898 is a fossorial crayfish species, which constructs its burrows in swampy areas in southeast Uruguay and in the state of Rio Grande do Sul, Brazil. The present field study was carried out in Lami, Porto Alegre, Rio Grande do Sul, Brazil, from May 2003 through August 2005. Environmental measurements (temperature, pH, dissolved ox

3. Modelagem numérica do fluxo da água no solo e do escoamento de base em uma bacia experimental em área agrícola no cerrado / Numerical modeling of the groundwater flow and the baseflow in an experimental watershed in an agricultural area of the cerrado biome, Brazil
This work presents an experimental study to evaluate the applicability of a groundwater numerical modeling tool, the FEFLOW, in simulating the water-table level variation and the baseflow in a watershed that is representative of agricultural areas of the Cerrado biome. For developing this study, some representative areas of this environment were selected, in

4. Monitoramento e modelagem de processos hidrogeomorfológicos : mecanismos de geração de escoamento e conectividade hidrológica
This dissertation discusses the runoff generation mechanisms and hydrological connectivity, based on monitoring and modeling of hydrogeomorphologic processes in the Saci Experimental Watershed (10 ha) completely covered with forest and located within the municipality of Rio Negrinho, Santa Catarina State, Brazil. An intensive monitoring system was implemente

5. Computation modeling of contaminant transport in watertable aquifers a case in the cemetery Bom Jadim, Fortaleza-Ce. / Modelagem Computacional do Transporte de Contaminantes em AqÃÃferos FreÃticos: Estudo de Caso Para o CemitÃrio Parque Bom Jardim, Fortaleza - Ce
A contaminaÃÃo de aqÃÃferos freÃticos adjacentes a Ãreas caracterizadas pela presenÃa de cemitÃrios de corpos humanos configura-se em uma realidade comum em muitas partes do Brasil e do mundo. Esta investigaÃÃo analisou a possibilidade dos nÃveis de contaminaÃÃo microbiolÃgicos encontrados em amostragem prÃvia da qualidade de Ãgua do aqÃÃfe

6. Solos do Projeto Xingó: caracterização e limitações ao uso com agricultura irrigada / Soil of the Xingó Project: characterization and limitations to irrigated land use
Soil research aiming irrigated land use have great importance in the semiarid Sertão zone of Sergipe state. With this purpose, four soil profiles were characterized and classified along a topossequence, including two Regolithic Nesols, a Planosol and a Luvisol. The objectives were to evaluate soil potential for irrigated land use and to produce information

7. Potato (Solanum tuberosum L.) and lettuce (Lactuca sativa L.) sensibility to water excess in soil. / Sensibilidade das culturas da batata (Solanum tuberosum L.) e da alface (Lactuca sativa L.) ao excesso de água no solo.
This work had as objectivies determinating the effects of root system flooding in three stages of growing of potato and lettuce crops, identifying the minimum water-table drawdown velocity necessary to avoid yield reductions and obtaining relations between relative yield and stress day index caused by excess of water in the soil. For these purposes two exper

8. Water consumption of estevia (stevia rebaudian a (Bert.) Bertoni) estimate by automatic microlysimeter. / Consumo de água da cultura da estévia (Stevia rebaudiana (Bert.) Bertoni) estimado por microlisímetro automático.
The aim of this work was to estimate the water consumption of stevia using two constant watertable microlysimeters and determine the irrigation levels response in the yield. The research was conducted at the Department of Agronomy and Agroecosystem Gestion experimental area of the Pisa University, in San Piero a Grado-Pisa/Itália. The reference evapotranspi

9. Aerobic biodegradation potential of subsurface microorganisms from a jet fuel-contaminated aquifer.
In 1975, a leak of 83,000 gallons (314,189 liters) of jet fuel (JP-4) contaminated a shallow water-table aquifer near North Charleston, S.C. Laboratory experiments were conducted with contaminated sediments to assess the aerobic biodegradation potential of the in situ microbial community. Sediments were incubated with 14C-labeled organic compounds, and the e
