Understanding the soil water dynamics during excess and deficit rainfall conditions over the core monsoon zone of India
...
Observations of soil moisture (SM) during excess and deficit monsoon seasons between 2000 to 2021 present a unique opportunity to understand the soil water dynamics (SWD) over core monsoon zone (CMZ) of India. This study aims to analyse SWD by investigating the SM variability, SM memory (SMM), and the coupling between surface and subsurface SM leve...

Physiological Responses of Typical Wetland Plants Following Flooding Process—From an Eco-Hydrological Model Perspective
Published in Frontiers in Ecology and Evolution
Anaerobics increase resistance to gas transport and microbial activity in flooded soils. This may result in the presence of aerenchyma in the roots of some wetland plants. Increased aerenchyma airspaces enable oxygen to be transported from the above-ground plant parts to the submerged roots and rhizosphere. Nevertheless, there is still a lack of st...

以长武地区为例,采用WinEPIC模型模拟1980—2018年间黄土高原旱作苹果园地深剖面土壤水分和水分生产力变化动态,以期为该区苹果产业的可持续发展提供科学依据。结果表明: 长武地区苹果园年均产量为26.37 t·hm-2,年均蒸散量为673.66 mm,年均水分生产力为4.07 kg·m-3,成龄果树水分胁迫天数主要受降雨量影响,果树生长后期年均胁迫天数为46.46 d,深层土壤含水量最早于9龄果树开始接近凋萎湿度。长武地区苹果整个生长周期内供水量是对果园产量影响最大的因素,深层土壤有效水含量降低是制约果树生长中后期产量提高的最主要因素,在降水不足的年份果树会利用更深层土壤水分。当深层土壤可利用水分较少时,过多的降水并未被果树利用,而是转化为浅层土壤水分蒸发。对于成龄果树在年供水量低于5...
Machine Learning vs. Physics-Based Modeling for Real-Time Irrigation Management
Published in Frontiers in Water
Real-time monitoring of soil matric potential has now become a common practice for precision irrigation management. Some crops, such as cranberries, are susceptible to both water and anoxic stresses. Excessive variations in soil matric potential in the root zone may reduce plant transpiration, due to either saturated or dry soil conditions, thereby...
Energy and water fluxes at the soil atmosphere interface of water repellent soils / Energie- und Wasserflüsse an der Gre...
Soil water repellency (SWR), the inhibited wetting of soils, is a characteristic shown by soils of all types and in all climatic regions around the world; SWR seems to be rather the norm than the exception. The hydraulic effects of SWR have been studied reasonably well and are still studied up to date. The effects of SWR on the soil atmosphere ener...
Response of soil water dynamics to precipitation years under different vegetation types on the northern Loess Plateau, C...
Published in Journal of Arid Land
Implementation of the Grain-for-Green project has led to rapid land cover changes and resulted in a significantly increased vegetation cover on the Loess Plateau of China during the past few decades. The main objective of this study was to examine the responses of soil water dynamics under four typical vegetation types against precipitation years. ...
