Determining the stable isotope composition of porewater using low temperature multi-step extraction for low water content soils J. Hydrol. (IF 4.5) Pub Date : 2021-02-13 Sanyuan Jiang; Wenbo Rao; Liangfeng Han
The δ2H and δ18O values (isotope values) of porewater in soils have been used as natural tracers in many research disciplines. Conventional methods to determine the isotope values of porewater require extraction of water from the soil. To extract soil porewater cryogenic vacuum distillation is a commonly used technique. Based on extraction techniques porewater can be considered to be composed of ‘extractable’

Towards predicting the initiation of overland flow from relatively flat agricultural fields using surface water coverage J. Hydrol. (IF 4.5) Pub Date : 2021-02-24 Chandra Prasad Ghimire; Willemijn M. Appels; Laura Grundy; Willis Ritchie; Stuart Bradley; Val Snow
On rough agricultural soils, initiation of overland flow is primarily related to the gradual filling of small depressions. As the volume of water ponding in local depressions increases, the connectivity of those depressions increases, and that connectivity permits flow across the field boundaries. Previous studies have aimed at predicting overland flow connectivity by means of depression storage, but

Rainfall intensity affects runoff responses in a semi‐arid catchment Hydrol. Process. (IF 3.256) Pub Date : 2021-02-23 Ze Tao; Min Li; Bingcheng Si; Dyan Pratt
The source and hydrochemical makeup of a stream reflects the connectivity between rainfall, groundwater, the stream, and is reflected to water quantity and quality of the catchment. However, in a semi‐arid, thick, loess covered catchment, temporal variation of stream source and event associated behaviors are lesser known. Thus, the isotopic and chemical hydrographs in a widely distributed, deep loess

The study of unsaturated behavior of soils pivots around the relationship between soil suction and the amount of water content present in the soil mass, which is termed as soil-water retention curve (SWRC). The drying SWRC is generally determined by neglecting the volume change behavior of the soil for low plastic soils. Such a procedure is bound by an inherent assumption that the soil exhibit zero
