- Abstract:
- ... Horizontal borehole ground penetrating radar (GPR) measurements can provide valuable information on soil water content (SWC) dynamics in the vadose zone, and hence show potential to estimate soil hydraulic properties. In this study, the performance of both sequential and coupled inversion workflows to obtain soil hydraulic properties from time-lapse horizontal borehole GPR data obtained during an ...

- Abstract:
- ... In the present paper a set of physically based expressions for estimating the infiltrated volume and the flow rate from hemispherical and disc sources are presented. The proposed formula depends on four parameters: the initial and the saturated soil water contents, the saturated hydraulic conductivity and the wetting front suction head. The developed models allow the accurate estimation of the inf ...

- Abstract:
- ... The decay constant k in the antecedent precipitation index (API) formula is generally determined arbitrarily and empirically, which causes great confusion in API calculation and comparison of different research results. In response to these problems, two hypotheses related to API (that is, k has the properties of optimality and multivaluedness) are proposed in this study. The daily runoff and dail ...

- Abstract:
- ... Soil water content or soil moisture content is considered one of the most critical properties of the soil for crop production, irrigation, and environmental studies. The technical development of soil moisture measurement devices is swift, but calibration among field conditions is still not entirely resolved. Accurate calibration requires samples taken right next to the sensor that disturbs the sit ...

While most aquatic diatom species have well-known autecological values for several important variables, qualifying them as biological indicators, this potential has not yet been untapped for terrestrial diatoms. Here, we aim to establish autecolo ...

Shallow-buried high-intensity mining (SHM) activities commonly in China’s western mining area will lead to the decrease of groundwater level and soil water content (SWC), which will aggravate the further deterioration of the local fragile ecological environment. In this study, the applicability and limitations of six typical soil dielectric models were comprehensively evaluated based on ground pen ...

This study used data collected from three cropland sites (two in Manitoba and one in Prince Edward Island) in Canada.In efforts to accurately describe the water dynamics in agricultural soils, most of the agri-hydrological models developed are highly complex, such that they require detailed input data, of which most of them are not always measured or otherwise readily available. However, the compr ...

In areas that experience frequent fluctuations in groundwater levels, changes in soil void space caused by fluctuations in groundwater levels directly affect the efficacy of soil vapor extraction (SVE). Most studies of SVE technology of oil-contaminated soil remediation do not consider fluctuations in groundwater levels.
