The high-resolution Experimental Advanced Airborne Research LIDAR (EAARL) is a new technology for cross-environment surveys of channels and floodplains. EAARL measurements of basic channel geometry, such as wetted cross-sectional area, are within a few percent of those from control field surveys. The largest channel mapping errors are along stream banks. The LIDAR data adequately support 1D and...

The marginal lagoons of the Sorocaba River fulfil important functions in their lotic ecosystems and for its fish communities, providing shelter, food, and area for fish early stages of development. The lagoons are also an escape from the river pollution since the physical-chemical characteristics of their water are more stable than the river water. Nevertheless, these lagoons are under a series...

River floodplains are spatially diverse ecosystems that respond quickly to flow variations and disturbance. However, it remains unclear how alteration hydrological disturbance impacts the structure biodiversity of complex microbial communities in these ecosystems. Here, we examined spatial seasonal dynamics aquatic (benthic) terrestrial habitats three hydrologically contrasting (natural flow, r...

Abstract Assessment of water surface profile in compound channels is essential for flood defence systems. Agriculture and development activities floodplains affect the floodplain shape over length, leading a converging channel. Few laboratory investigations proved overbank flow floodplains. Therefore, innovative precise approaches are still great demand. In this paper, new approach has been pro...

Droughts inflict significant loss on agricultural economies. Gomati River basin, the area of present study, is located within Ganga floodplains, which approximately coincide with north central temperature homogeneous region (NCTHR) India. basin a non-perennial one supporting water intensive crops. To ascertain occurrence droughts (if any) from 1986 to 2015 in terms inter-dependencies drought ca...

Natural floodplains are ecosystems with a diverse mosaic of habitats and site conditions, but also highly threatened due to anthropogenic pressures. Plant species occur in all habitat types can indicate their value for nature conservation. To improve sustainable management rivers floodplains, several indices such as the River Ecosystem Service Index (RESI) have been developed. However, there so...

Installing conservation fences to prohibit feral animal access wetlands can become a barrier for non-target species of interest. We collected 161 turtles (Chelodina rugosa, Emydura subglobosa worrelli, Myuchelys latisternum) from twenty floodplain and riverine during post-wet (June–August) late-dry season (November–December) surveys (2015–2018) in northern Australia. Wetlands were fenced (150 ×...
