Abstract

International audience; Water transport in the vadose zone greatly depends on the hydric properties of soils which exhibit high variability whatever the spatial scale analysed. The determination of those properties in the field or in the laboratory involves considerable uncertainty. Recently, inverse modelling has been introduced to obtain hydric properties in situ by deducing from a measured time series of soil water content. Anyhow, the soil water content is commonly obtained by gravimetric measurements on soil samples, TDR measurements or neutron probes measurements. At the field scale, these methods give only punctual information on soil water content, with a low spatial resolution. Financial and time constraints limit the numbers of measurements locations and thus the description of the soil water content. Since recently, geophysical methods enable the monitoring of some soil characteristics on a continuous space with a high resolution. One of them, the electrical resistivity (ohm.m) -or DC method- is well adapted to characterise the soil subsurface and to describe soil properties, even if they are time-dependent. However the electrical resistivity depends on several chemical and physical soil variables that can interact. The influence of one soil parameter like the soil water content on the electrical resistivity is then hard to estimate. Our objective was then to use spatial measurements of electrical resistivity, to define zones of homogeneous electrical resistivity with time, to interpret them in terms of evolution of water content, and to compare them with a soil map. Our assumption was then that the time variation of electrical resistivity at the field scale was only due to the evolution of the soil moisture in our studied field. A time monitoring of the soil electrical resistivity and the soil moisture was realized during the year 2006, at four dates, both by the MUCEP device (MultiContinous Electrical Profiling), that gives measurements on a whole field area, and by local gravimetric measurements of the soil water content. Homogeneous zones were defined directly from measurements for the electrical resistivity, and after ordinary kriging for the water content. Our analysis of the spatial and temporal variability has permitted to discriminate three temporal homogeneous zones, both for electrical resistivity and the water content, that were mainly related to the soil map. We show that the use of electrical measurements enables (1) to directly describe the spatial and temporal evolution of soil water content at the field scale and (2) to extrapolate the temporal evolution of the water content in unknown zones. We could then describe some hydric processes, like lateral flows or upward capillary flows that would be difficult to derive from soil maps.

Abstract

International audience; Since recently, geophysical methods enable the monitoring of some soil characteristics on a continuous space with a high resolution. However the interpretation of electrical measurements is difficult because the geophysical data are influenced by many soil variables, that vary, or not, with time. Our objective was then to use spatial measurements of electrical resistivity, to define zones of homogeneous electrical resistivity, to interpret them in terms of evolution of water content, and to compare them with a soil map. Our assumption was then that the time variation of electrical resistivity at the field scale was only due to the evolution of the soil moisture in our studied field. A time monitoring of the soil electrical resistivity and the soil moisture was realized during the year 2006, at four dates, both by the MUCEP device (MultiContinous Electrical Profiling), that gives measurements on a whole field area, and by local gravimetric measurements of the soil water content. Homogeneous zones were defined directly from measurements for the electrical resistivity, and after ordinary kriging for the water content.

Abstract

International audience; The present study re-examines the influence of ecological conditions on the health of silver fir (Abies alba) measured in 1989, during the so-called forest decline crisis, in the sandstone portion of the Vosges mountains, on the basis of an assessment of almost 3000 forest management units (10–20 ha each). Relationships between defoliation and needle yellowing (related to Mg deficiency) and environmental factors were analysed with contingency tables and modelled using discriminant functions. The results confirmed the predominant influence of altitude and stand age; these two factors explain 70% of the spatial variability of defoliation and 64% of that of yellowing. In addition, a database composed of 178 soil analytical profiles was analysed in relation to the geographic database. The commonly used variable “altitude” appeared to combine the influence of several related variables which are crucial for the biological functioning of the tree: especially the plant available water holding capacity and chemical characteristics were negatively correlated with elevation in the study area. This ecological feature is likely to be common to a number of mid-elevation mountain range in Europe and was often neglected in the earlier studies on forest decline; Ce travail réexamine l’influence des conditions écologiques sur le dépérissement du sapin, mesuré lors de la crise du dépérissement forestier dans les Vosges, sur la base d’une notation exhaustive de 3 000 parcelles forestières (10–20 ha) gérées par l’Office National des Forêts dans les Vosges gréseuses. Les relations entre défoliation et jaunissement des aiguilles (généralement dû à une carence en Mg) et les conditions environnementales moyennes de chaque parcelle ont été étudiées par des tableaux de contingence, et modélisées en utilisant une analyse discriminante. L’altitude et l’âge des peuplements expliquent respectivement 70 % de la défoliation et 64 % du jaunissement. Le paramètre « altitude » combine de nombreux facteurs influençant le fonctionnement physiologique de l’arbre. En utilisant une base de données de 178 profils pédologiques, nous montrons que l’altitude est négativement corrélée à la réserve utile des sols et au taux de saturation, indépendamment du type de grès. Ce type de distribution est probablement assez banale dans un certain nombre de moyennes montagnes européennes, et forme un biais souvent négligé dans les études de dépérissement

Abstract

The impact of agricultural practices on the spatial distribution of trace elements (TEs) in the surface horizon of Albeluvisols was studied by comparing three types of situation with an increasing anthropogenic gradient: a forest soil, considered as a reference, and cultivated soils with and without spreading of sewage sludge. Total cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn) were determined in soil surface horizons. The quantity of particles finer than 2 µm, organic carbon (OC), iron (Fe), manganese (Mn), and calcium (Ca) contents were also measured and used as tracers of soil components that may have contained TEs. Governing factors of the spatial variability of TEs were searched for through comparison of the descriptive statistics (mean and coefficient of variation) and the determination of the best multivariate model predicting TE contents. Nickel and Cr distributions seem to be mainly linked to variability of the parent material composition, whereas that of Co is related to redox pedological processes. In addition, agricultural practices play a role in TE distribution, through the input of TEs, mostly Cd, Cu, and Zn, via sewage sludge spreading and liming amendments, and lateral (homogenization) and vertical (mixing of horizons) redistribution through tilling the soil.

22. Spatial and temporal monitoring of soil water content with an irrigated corn crop cover using surface electrical resistivity tomography.

Author

Michot, Didier, Benderitter, Yves, Dorigny, Abel, Nicoullaud, Bernard, King, Dominique, and Tabbagh, Alain

Abstract

A nondestructive and spatially integrated multielectrode method for measuring soil electrical resistivity was tested in the Beauce region of France during a period of corn crop irrigation to monitor soil water flow over time and in two-dimensional (2-D) with simultaneous measurements of soil moisture and thermal profiles. The results suggested the potential of surface electrical resistivity tomography (ERT) for improving soil science and agronomy studies. The method was able to produce a 2-D delimitation of soil horizons as well as to monitor soil water movement. Soil drainage through water uptake by the roots, the progression of the infiltration front with preferential flow zones, and the drainage of the plowed horizon were well identified. At the studied stage of corn development (3 months) the soil zones where infiltration and drainage occurred were mainly located under the corn rows. The structural soil characteristics resulting from agricultural practices or the passage of agricultural equipment were also shown. Two-dimensional sections of soil moisture content were calculated using ERT. The estimates were made by using independently established 'in situ' calibration relationships between the moisture and electrical resistivity of typical soil horizons. The thermal soil profile was also considered in the modeling. The results showed a reliable linear relationship between the calculated and measured water contents in the crop horizon. The precision of the calculation of the specific soil water content, quantified by the root mean square error (RMSE), was 3.63% with a bias corresponding to an overestimation of 1.45%. The analysis and monitoring of the spatial variability of the soil moisture content with ERT represent two components of a significant tool for better management of soil water reserves and rational irrigation practices.

Abstract

Abstract: The modeling of soil erosion by water supposes an accurate and thorough understanding of the hydrology. Thus, it is critical to have a good delineation of the surface flow path. The flow network data are critical for important uses such as flood forecasting and watershed management. Geographic Information System (GIS) functions are able to compute a flow network directly from the digital elevation models. Because the flow directions are only based on the topography, the other factors controlling the flow directions are overlooked. In the agricultural areas, work such as tillage can have a large impact on the flow direction. We propose a 5-step procedure to account for such man-made features. The use of this procedure clearly improves the quality of the computed flow network. This procedure has been successfully implemented in a GIS and improves the prediction of surface flow and therefore improves water erosion modeling at the watershed scale. [Copyright &y& Elsevier]
