Small scale fishing profits in two communities in the Upper Paraná River floodplain (Porto Rico - PRI and Porto São José - PSJ villages) are assessed based on interviews carried out with professional fishermen. There is a high illiteracy level in both PRI (50%) and PSJ (44.5%). The main contributions to income are "vessel costs" and "fish consumption" by the family. Specific tackle (such as cev...

Green infrastructure approaches have attracted increased attention from local governments as a way to lower flood risk and provide an array of other environmental services. The peer-reviewed literature, however, offers few estimates of the economic impacts of such approaches at the watershed scale. We estimate the avoided flood damages and the costs of preventing development of floodplain parce...

Anastomosing rivers constitute an important category of multi-channel rivers on alluvial plains. Most often they seem to Ž . form under relatively low-energetic conditions near a local base level. It appears to be impossible to define anastomosing rivers unambiguously on the basis of channel planform only. Therefore, the following definition, which couples floodplain geomorphology and channel p...

The changes imposed by dams on hydrological regime, water transparence and nutrient concentrations downstream affect biodiversity in relation to species richness and specific composition of the community. The aim of this work was evaluate this effect on periphyton, comparing richness and composition of periphytic algae in the Garças Lake, Upper Paraná River floodplain, between the years 1994, b...

Detecting the action of selection in natural populations can be achieved using the QST-FST comparison that relies on the estimation of FST with neutral markers, and QST using quantitative traits potentially under selection. QST higher than FST suggests the action of directional selection and thus potential local adaptation. In this article, we apply the QST-FST comparison to four populations of...

The transfer of water, sediment, and other materials to floodplains is a function of the hydrology of inundation. Inundation of floodplains by regional water, that is, overbank flow from the main river channel, and local water, that is, groundwater, hyporheic water, local tributary water, and direct precipitation onto the floodplain, is such that some rivers inundate dry floodplains, while othe...

The use of engineering risk analysis and multi-objective decision-making under risk are considered as tools for floodplain management and extreme flood protection. Distinction is made between (a) the catchment or large scale planning and (b) the local or small-scale design of protection measures. After defining the risk of flooding at different scales and specifying the multiple criteria that m...

Abstract This article analyzes residential property transactions to better understand the impact of urban flooding events and distributions on floodplain real‐estate markets. We studied patterns before after major fluvial in three counties that experienced such between 2009 2013: Benton County, Oregon; Boulder Colorado; Cass North Dakota. tested for presence distribution price discounting follo...

Large-scale reconstruction measures are being prepared and implemented in river basins of north-western Europe for the purpose of flood defence, ecological rehabilitation and infrastructural improvements. These measures will have far-reaching consequences for the physical structure, hydrodynamics, and hence for the ecological functioning and biodiversity of riverfloodplain ecosystems. River man...
