WebHowever, salt accumulation in spring irrigation fields was 35.68 and 16.87% in freezing and melting stages, respectively. During the whole freeze-thaw period, the net salt flux in each layer of autumn irrigated and spring irrigated fields was negative, but it increased with the increase of soil depth. WebSoil dissolved organic matter (DOM) plays a vital role in biogeochemical processes. Global warming leads to increased freeze-thaw cycles (FTCs) in boreal forest soils, which can change DOM production and consumption. However, the interactions between the chemical composition of DOM molecules and the microbial communities that drive C …

WebDec 1, 2013 · The model Soil‐Litter‐Iso (SLI) calculates coupled heat and water transport in soil. It was recently implemented into the Australian land surface model CABLE, which is the land component of the Australian Community Climate and Earth System Simulator (ACCESS). Here we extended SLI to include accurate freeze‐thaw processes in the soil … WebDec 1, 2013 · The experimental area is characterized by low biomass, high soil moisture dynamic range, and typical freeze–thaw cycle. The network consists of 56 stations with their elevation varying over 4470–4950 m. As auxiliary parameters of this network, soil texture and soil organic carbon content are measured at each station to support further studies. impacts on flooding
A decision tree algorithm for surface soil freeze/thaw …
WebWarming can result in thawing of the soil and its consequent weakening of support for a structure as the ice content turns to water; alternatively, where structures are built on piles, warming can cause movement through creep … WebMar 17, 2024 · The result, a new and robust decision tree-based classification algorithm which introduces a freeze/thaw probability metric, soil specific classifications, and improved resolution. This information is expected to provide better inputs to hydrologic models used to predict runoff and flooding, ... WebDownslope mass-movement of soils and heavy rains during the thawing period Rep.
