Flood Pulse Irrigation of Meadows Shapes Soil Chemical and Microbial Parameters More Than Mineral Fertilization

Soil Systems, 2021
While mineral fertilization increases agricultural yields, it also bears the risk of contaminating non-target ecosystems and negatively affecting soil chemical parameters and microbial communities.

Response of Prochilodus nigricans to flood pulse variation in the central Amazon [PDF]

Royal Society Open Science, 2018
The influence of the flood pulse on fish populations has been posited, but infrequently tested or quantified. Here, we tested the effect of habitat on population size, using Prochilodus nigricans as a case study species.

Influence of Flood Pulse on Termite Diversity (INSECTA: ISOPTERA) in the Pantanal [PDF]

Sociobiology, 2017
This research aimed to associate termite diversity to flood pulse by Paraguay River, and with savannas and pasture areas. The study was conducted nearby the town of Cáceres, in Pantanal - Mato Grosso, on six livestock farms subject to Paraguay River ...

Alteration of flood pulses by damming the Nenjiang River, China – Implication for the need to identify a hydrograph-based inundation threshold for protecting floodplain wetlands

Ecological Indicators, 2021
Floodplain wetlands of low-gradient rivers are especially sensitive to alteration of hydrologic conditions. Although many studies have investigated changes in downstream hydrologic regimes caused by river dam construction, no study has specifically ...

Conservation tillage and sprinkler irrigation for sustainable water management and enhanced crop yields in maize and field pea cropping system [PDF]

Scientific Reports
The conservation agriculture (CA)-based approaches, including zero tillage (ZT)/reduced tillage (RT) with pulse-based cropping systems, support climate resilience in the long-run.

Forecasting the flood-pulse in Central Amazonia by ENSO-indices

Journal of Hydrology, 2007
Summary The flood-pulse of the large rivers in Central Amazonia triggers ecological processes of the floodplain systems inducing a severe seasonality in the annual cycle between the aquatic and the terrestrial phase. The nutrient-rich floodplains (varzea) have the highest human population density in Amazonia and economic activities such as fishing ...

Climate Change Impacts on Flood Pulse Characteristics in the Barotse Floodplain, Zambia

Earth's Future
Tens of millions of livelihoods depend on floodplains, making them especially vulnerable to climate change. However, understanding how annual floods may change and impact local vulnerabilities remains limited.

River damming affects seedling communities of a floodplain forest in the Central Amazon [PDF]

Acta Botânica Brasílica, 2020
The flood pulse of black water rivers in the Amazon basin determines the composition of species along the flood gradient in igapó forests. The Balbina dam, built on the Uatumã River, has altered the flood pulse and caused changes in the floristic ...

Flood-Pulse Variability and Climate Change Effects Increase Uncertainty in Fish Yields: Revisiting Narratives of Declining Fish Catches in India’s Ganga River

Hydrology, 2022
River-floodplains support a significant number of small-scale capture fisheries despite having undergone degradation due to human modification of river flows by dams, pollution, and climate change. River fish production is underpinned by the annual flood-

FLOODING CHARACTERISTICS OF A PULSE EXTRACTION COLUMN [PDF]

AIChE Journal, 1954
AbstractAn investigation using the hexone‐water system was made of flooding in a 1‐in.‐diam. ten‐plate pulse column. An analysis of column operation led to the derivation of an equation for predicting conditions of inadequate pulsation and for establishing the amount of liquid recycled under any operating conditions.
