18 Many dryland areas are being converted into intensively managed irrigation crops, what 19 can disrupt the hydrological regime, degrade soil and water quality, enhance siltation, 20 erosion and bank instability, and affect biological communities. Still, the impacts of 21 irrigation schemes on the functioning of terrestrial and aquatic ecosystems are poorly 22 understood. Here we assess the ef...

Rocky shores provide a harsh environment for marine organisms and we briefly discuss natural sources of variation in community structure before considering anthropogenic impacts in detail. We review impacts caused by (a) acute disturbances: oil spills, toxic algal blooms and (b) chronic disturbances: nutrient pollution, oil, heavy metals, pesticides, antifouling paints, collecting, trampling/ha...

Muddy coast due to natural and human-induced factors can be variable over a wide range of different spatiotemporal scales. Our limited capability understand especially predict this variability lead misinterpretation muddy coastal change information, which hampers informed decision-making subsequent design implementation engineering interventions. Therefore, the research on evolution historical ...

The effectiveness of small reservoirs in a mountain landscape continuously decreases over time due to the gradual siltation. We examined two hypotheses about enhanced siltation rate and constant relative contribution unpaved roads water reservoir period 1990–2014, with pronounced climate change, compared reference 1970–1989. Analysis was based on deposit volumes extracted from 1989 detected at ...

An application of regression relationships depending on geomorphic parameters is proposed to predict the amount of the average annual suspended sediment yield at different sections of the drainage network. Simple and multiple regression relationships, utilising the drainage density and the hierarchical anomaly index as independent variables, based on data from 20 river basins of different size ...
