To analyze the changes in the Upper Danube Floodplain, we used aerial photos to quantify the change of landscape pattern from 1963 to 2010. We focused on typical floodplain habitats, i.e., riparian forest and floodplain grassland. We used landscape metrics and transformation matrix to explore changes in land cover structure and composition. The active floodplain experienced increasing fragmenta...

the purpose of this study was to compare the dez river water quality in the dezful hydrometric station for human drinking water, industry and agriculture. this study by cross-sectional method used data from the period of 39 years. sampling was carried out on the basis of physical and chemical parameters were determined. the results with world health organization standards, charts schuler and ag...

Based on a brief account of 1,000 years of river floods and flood management in the Dutch Rhine delta, it is argued that vulnerability to river floods depends on the complex interaction of economics, institutions, politics and, to a limited extent, climate. Response functions and thresholds for climate change impacts should take this complexity into account rather than assuming society to be co...

Hydromorphological deficits are of real concern regarding the goals of the European Water Framework Directive to reach a good ecological status. The effects of measures that change the morphological structure of a river is hard to predict. Existing methods to simulate this process in a traditional numerical model can not be applied to whole river systems. Using a rule-based modelling concept to...

A river network is a typical completely open system formed by interconnected river channels. The interactions between the imports of a river (water and sediment) and the channel will cause the change of the channel patterns. This is actually a feedback between the erosion and the sedimentation states of the channel via an adjustment of the sedimentcarrying capability of the stream. This feedbac...

This study aims to evaluate the environmental factors determining of the changes in phytoplankton structure in spatial (upper, middle and lower course) and seasonal (dry and rainy period) scales in a eutrophic river (Almada River, northeastern Brazil). In the study period, total accumulated rainfall was below of the historic average, resulting in flow reduction, mainly in rainy period. High ort...

The lower Missouri River Basin has experienced increasing streamflow and flooding events, with higher risk of extreme hydrologic impacts under changing climate. The newly available North American Regional Climate Change Assessment Program (NARCCAP) climate projections were used as atmospheric forcing for Soil and Water Assessment Tool (SWAT) model which runs with varying potential evapotranspir...
