This study explores how catchment heterogeneity and variability can be summarized in simplified models, representing the dominant hydrological processes. It focuses on Mediterranean catchments, characterized by heterogeneous geology, pedology, and land use, as well as steep topography and a rainfall regime in which summer 5 droughts contrast with high-rainfall periods in autumn. The Ardèche cat...

Even in physically based distributed hydrological models, various remaining parameters must be estimated for each sub-catchment. This can involve tremendous effort, especially when the number of sub-catchments is large and the applied hydrological model is computationally expensive. Automatic parameter estimation tools can significantly facilitate the calibration process. Hence, we combined the...

Em função dos avanços sistemas de produção agropecuária e da crescente demanda por alimentos no mundo, ainda é proeminente, a necessidade se investigar as relações existentes entre os atributos do solo diferentes condições ambientais em que estão inseridos. Existem diversos produtos científicos apresentam caracterizações solos brasileiros, contudo, dependendo aplicação, maiores limitações vincu...

O presente trabalho pretende mensurar o nível de susceptibilidade à erosão antrópica nos limites territoriais do estado Ceará, através da análise dos fatores ambientais envolvidos no processo, como: litologia, declividade, pedologia, intensidade chuva, cobertura vegetal solo e seus tipos ocupação. Como instrumentos pesquisa, foram utilizadas imagens sensores OLI TIRS a bordo satélite Landsat 8,...

Watersheds occupy a vulnerable position with regards to issues associated anthropogenic changes. The state of Maranhão stands out in Brazil for its water resources. the Eastern Coast (ECWSM) are located Hydrographic Region Western Atlantic. present paper characterizes physiography ECWSM Maranhão, highlighting components and natural potential (altimetry, declivity, soils, vegetation, resources, ...
