spatial relationships between soil moisture patterns

Relation between precipitation location and antecedent

Jun 17 2017Assuming that this relation between preferential precipitation location and antecedent soil moisture is deterministic our results suggest the coexistence of positive and negative soil moisture‐precipitation spatial feedback mechanisms and a competition between them for the dominance in a given soil moisture pattern

Frontiers

In recent decades while great emphasis has been given to the monitoring of point-scale soil moisture patterns and field-scale integrated soil moisture the measurement of matric potential has attracted little attention Information on the soil matric potential is available in point-scale measurements but is still missing at field-scale This state variable is necessary to understand

Relationships between plant diversity and soil microbial

However contradictory results have been found when examining their relationships particularly at broad spatial scales To address this issue we conducted a meta‐analysis to evaluate the patterns in the correlation between plant diversity and soil microbial diversity and the underlying factors driving the relationship

Relations between the spatial patterns of soil moisture soil depth and transpiration and their influence on the hillslope water balance are not well understood When determining a water balance for a hillslope small scale variations in soil depth are often ignored

Mechanism Underlying the Spatial Pattern Formation of

Specifically we analyzed (1) whether there was a corresponding relationship between soil and trees by analyzing the spatial pattern of soil moisture pH and nutrients and that of the four dominant species namely Populus davidiana Betula platyphylla Larix gmelinii and Acer mono and (2) the effect of light-blocking by adult trees on saplings

HESS

Abstract Soil moisture at the catchment scale exhibits a huge spatial variability This suggests that even a large amount of observation points would not be able to capture soil moisture variability We present a measure to capture the spatial dissimilarity and its change over time Statistical dispersion among observation points is related to their distance to describe spatial patterns

Spatial and temporal variability of soil moisture in

Aug 06 2018This research has been tried to evaluate the spatial and temporal variability of surface soil moisture (SM) in a semi-arid and cold region of Ardabil Province in Iran with an area of about 10 000 km2 The used SM data is the SMAP Enhanced L2 Radiometer Half-Orbit 9 km Soil Moisture provided by NASA The study area was subdivided into 120 locations consisting 10 12 grids matching with

The Relationship between an Invasive Shrub and Soil

Recent studies indicate that positive relationships between invasive plants and soil can contribute to further plant invasions However it remains unclear whether these relations remain unchanged throughout the growing season In this study spatial sequences of field observations along a transect were used to reveal seasonal interactions and spatially covarying relations between one common

Spatial Variation of Soil Properties Relating to

Bekele and Hudnall provide an interesting perspective on the spatial variation of soil chemical properties in a natural area undergoing transition from prairie to forest Their focus is on the unique calcareous prairie ecosystem of Louisiana where prairie remnants are being encroached upon by the forest primarily eastern red cedar (Juniperus iana L )

Small scale variations in soil depth affecting the

Relations between the spatial patterns of soil moisture soil depth and transpiration and their influence on the hillslope water balance are not well understood When determining a water balance for a hillslope small scale variations in soil depth are often ignored In this study we found that these variations in soil depth can lead to distinct patterns in transpiration rates across a hillslope

Spatio

Spatial patterns of soil moisture and their temporal development were analyzed using nine different datasets from the Rur catchment in Western Germany For all datasets we found negative linear relationships between the coefficient of variation and the mean soil moisture indicating lower spatial variability at higher mean soil moisture

Apr 05 20191 My spatial problem A description of the research question that you are exploring Research question: How is the spatial pattern of juniper density (A) related to the spatial pattern of slope aspect and a combination of the two (B) via soil moisture and solar radiation? The expansion of western juniper has become a concern in many rangeland areas and is associated with a number of

Scaled spatial variability of soil moisture fields

patterns among soil moisture statistics across a variety of landscapes Specifically the relationships between mean soil moisture and spatial variability of soil moisture mea-surements are quantified Spatial variability patterns are examined in light of local physical properties including climate soil topography extent and vegetation

Relationships between spatial environmental heterogeneity

Relationships between spatial environmental heterogeneity and patterns is that spatial heterogeneity in resource availability is maximal at intermediate productivity Measures of soil moisture content water depth vascu-lar plant cover and density and the relative abundance

Relationship of Salt Marsh Vegetation Zonation to Spatial

An intertidal San Francisco Bay salt marsh was used to study the spatial relationships between vegetation patterns and hydrologic and edaphic variables Multiple abiotic variables were represented by six metrics: elevation distance to major tidal channels and to the nearest channel of any size edaphic conditions during dry and wet circumstances and the magnitude of tidally induced changes
