A more complete understanding of scour mechanisms for flows downstream grade-control structures, including their temporal evolution, has the potential to lead improved predicting tools design. To date, design equations have been mostly derived empirically, i.e., by parametric modelling (at generally-small scales) corresponding specific structure configurations, and limited ranges hydraulic cond...

Gully rehabilitation is often applied as part of catchment management strategies aimed at reducing downstream sediment yields. However, the influences gully control measures on runoff and transport processes in agroforestry systems have been seldom studied. In this paper, a thorough analysis these was carried out valley-bottom located dehesa from SW Spain. The monitored before after implementat...

As global temperatures rise, flooding and storm surges caused by extreme weather threaten people’s safety nations’ development. Nature-based Solutions (NBS) are practical actions to support resilience reduce flood risk applied in many countries. the NBS approach mentions, small check dams made of gabion wood can retain runoff temporarily create detention basins magnitude floods provide addition...

check dams, are small dams in the watershed. these dams are constructed in susceptible areas to erosion due to reduce of flow velocity and erosion, control of sediment and flood in upstream of reservoir dams. these structures are made using wood, stone and cement, and gabion. these structures change the hydrological response of the watershed by reducing flow velocity, the channel slope and stor...

Flood-based Agricultural Systems (FAS), which rely on temporary floods, provide livelihoods for nearly 50 million smallholder farmers across water-stressed African basins. This paper analyses the impact of externally driven agricultural production and productivity improvement interventions in FAS, taking Ethiopian Fogera floodplain as a case study. Ostroms’ Governing Commons Principles were use...

and canyon sediments in several canyon reaches are contaminated with low-levels of radionuclides from hisFollowing the May 2000 Cerro Grande fire at Los Alamos, NM, toric LANL operations (Reneau et al., 1998). To mitisurface water control structures were constructed near Los Alamos to mitigate the transport of contaminant-bearing sediment toward the gate potential off-site migration of these se...
