The paper addresses the role of the conceptual rainfall-runoff modelling approach in hydrology on a scientific and technological context. From this analysis, suggestions for modelling and further research in this field are proposed.

This section describes the boundaries and the main physical and socioeconomic characteristics of the region in order to define the area considered in the regional GIWA assessment and to provide sufficient background information to establish the context within which the assessment was conducted. Brazil Current, GIWA region 39, is a tropical/sub-tropical ocean margin governed by western boundary ...

Do runoff elections, using the same voting rule as the initial election but just on the winning candidates, increase or decrease the complexity of manipulation? Does allowing revoting in the runoff increase or decrease the complexity relative to just having a runoff without revoting? We show that, for both weighted and unweighted voting, every possible answer can be made to hold, even for elect...

soil erosion is an abstruse phenomenon which contains segregation and transmission of soil particles and runoff from rainfall and infiltration. runoff and sediment generation was compared using rainfall simulator in grassland (st. parviflora-br. tomentellus) and shrubland (as. parrowianus-as. gossipinus). for this purpose, vegetation map was supplied for two vegetation types four main aspects a...
