“…The other groups, such as eutric nitosols, and ferric luvisols, are more suited for agricultural applications since they can store more water. Furthermore, the presence of quartz, feldspar, plagioclase, anatase, hematite, and magnetite, and so on, gives ferric luvisols their characteristic red color (Pospíšilová et al., 2021).…”

Understanding the origins and hotspots of suspended sediments is crucial for safeguarding the biotic communities and for management of water quality in river‐reservoir systems. This study is an attempt to develop a new analytical framework to deconvolve the suspended sediment sources contribution using a novel index (i.e. erosion susceptibility index, ESI). The ESI is computed using sediment fingerprinting information, sediment yield, and the areal coverage of the sediment sources (land use). We have used X‐ray diffraction (XRD) and Partial least square regression (PLSR) based spectral fingerprinting technique to apportion the land use classes as sources of sediments in a representative catchment of Chotanagpur Plateau (CP), India (Konar reservoir catchment). PLSR model on the XRD spectra has performed well with R2 > 0.88 and identified agricultural areas as the major contributor of suspended sediments by delivering 28% to 43%, varying seasonally (in the period of 2018‐2019). However, based on the ESI values barren lands and human settlements were found to be the most crucial land use classes (with highest ESI value of 1.31 and 1.08 respectively) in terms of sediment generation (22% to 29% and 14% to 23% respectively) with only 14% and 12% areal coverage. The results have demonstrated that the state of critical conservation urgency of different land uses can be quantified more effectively when combining spectral tracers based knowledge with ESI.

“…In the Czech Republic, the typical natural floodplain forests are situated near the confluence of the Morava and Dyje rivers, at the Litovelské Pomoraví floodplain, and the Labe and Odra floodplains (Machar 2013;Menšík et al 2015;Pospíšilová et al 2020). According to Cornelissen et al (2019), the typical process of alluvial soil formation is stratification, the presence of short-term extreme floods, and groundwater table fluctuations.…”

Land use changes together with riverbed regulations to avoid the annual floods affect the ecosystem of floodplain forests. Later subsequent revitalization measures, transboundary controlled river management, wetland restoration, and integrated planning were realized to reduce the negative effect of groundwater dropping and other environmental problems. This study aimed to follow the dynamic of groundwater level, soil properties and forest vitality as affected by climate change. The continuous dataset (2019-2022) of soil physical and hydrophysical parameters and tree radial growth parameters were obtained. Groundwater level was evaluated by z-score and the means, and standard deviation values were considered. The monthly assessment of soil and climatic conditions showed that the uneven distribution of rainfall and the increase in temperatures have significantly affected the soil hydrological regime and forest growth. Continual monitoring is necessary to prepare projection models, which can help better understand both the soil and tree growth parameters in the changing environment.

Loess is a large-scale deposit which is easy to mine and widely distributed on the epipedon. The clay fraction of loess, also known as 'loessial clay', is a very important component of loess which affects its properties and performance. From a 'materials' perspective, the clay fraction of loess has been ignored. Recently, loess particles have attracted interest because of their potential applications. The focus in the current review is on the methods of modifying loess particles and their application as functional materials. The major components of loess particles are clays, calcite, and quartz, with the clays including kaolinite, illite, montmorillonite, and chlorite. Loess has a range of particle sizes, types, and dispersibilities. The particles agglomerate readily, mainly because cementation occurs readily in the clay fraction. Loess particles can be modified and their properties can be improved by compaction, separation, purification, acidification, calcination, surfactant modification, geopolymerization, and polymer modification. Loess-based functional materials have been used as sorbents, eco-friendly superabsorbents, soil and water conservation materials, humidity-regulating materials, and building materials. Separated and purified loess particles can adsorb metal ions and harmful elements directly. Surfactant-modified loess particles can remove organic compounds effectively. After modification with polymers, loess particles exhibit greater capacity for the removal of environmental pollutants such as harmful metal ions and dyes. As a superabsorbent, modified loess shows excellent thermal stability and swelling behavior. Calcined loess could be utilized as an energy-saving building material with good humidityregulating performance, and geological polymerization has further expanded the scope of applications of loess in architecture. In summary, loess-based functional materials, which are inexpensive and ecologically friendly, deserve more attention and further development. Keywords-Application . Clay . Functionalization .

Using the geological and geographical classification, loess has been divided into plateau, intermontane basin,
