Runoff production in blanket peat covered catchments [PDF]

, 2000
Although blanket peat covers many major headwater areas in Britain, runoff production within these upland catchments is poorly understood. This thesis examines runoff production mechanisms within the blanket peat catchments of the Moor House National ...

Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Preferential Flow Infiltration Model for Wide Grading Soils Subject to Rainfall Infiltration

工程科学与技术, 2017
:Pore diameters of wide grading soil are across several orders of magnitude.A preference flow which is a kind of unbalanced infiltration in space usually appears under rainfall infiltration condition.Based on the fractal structure of pores,quantitative ...

EFFECT OF SURFACE BOUNDARY CONDITION ON RAINFALL INFILTRATION

, 2006
Rainfall infiltration is greatly influenced by the surface boundary condition as well as hydraulic properties of soil. This paper highlights the study on the effect of several surface boundary conditions on the rainfall infiltration using a computer ...

Transforming Agricultural Water Management for Healthy People and Planet: Thinking Beyond Water

Irrigation and Drainage, EarlyView.
ABSTRACT This paper develops the concept of Thinking Beyond Water, a transdisciplinary paradigm that reframes agricultural water management (AWM) as a systems catalyst for planetary health, equity, justice and resilience. Moving beyond conventional irrigation‐centric models, we reimagine AWM through integrative frameworks such as the planetary ...

An improved Green-Ampt model for rainfall infiltration analysis of multi-layered heterogeneous soil slopes

Yantu gongcheng xuebao
The rainfall infiltration analysis of slopes is of a great significance to the reinforcement design, mitigation and risk mitigation of rainfall-induced landslides. The classical Green-Ampt model, whose parameters have clear physical meanings and which is

Construction and Application of a Novel C‐Vine Copula‐Based Multi‐Variate Ecological Drought Index

Irrigation and Drainage, EarlyView.
ABSTRACT A comprehensive ecological drought index capturing vegetation growth conditions and meteorological–hydrological variability is essential for assessing ecological drought and optimizing water resource management. This study selected soil moisture (SM), actual evapotranspiration (ET), land surface temperature (LST) and leaf area index (LAI) to ...

Metal Accumulation, Liver Histopathology, and Human Health Risk Assessment Across Different Trophic Guilds in a Mining‐Affected Neotropical River

Journal of Applied Toxicology, EarlyView.
ABSTRACT Metal pollution in aquatic environments represents a recurring global concern; however, traditional paradigms often assume linear bioaccumulation patterns that may fail under catastrophic contamination scenarios. This study evaluated metal concentrations in water, sediment, and tissues of 10 fish species from different trophic guilds in the ...
