“…Nonetheless, all environmental factors are related, and isolating one from the others is difficult. For example, antecedent soil moisture in a storm result from the interaction between soil properties and the hydrological and meteorological conditions (Wang et al, 2023). To address this last problem of USLE family models, some studies recently implemented the structural equation modelling approach where driver–factors interactions on SEW have been identified; indeed, the inclusion of that interactions in a prediction model has improved soil loss rate estimations at plot scale (Ke & Zhang, 2022; Tian et al, 2023).…”

Research on soil erosion by water (SEW) includes studies on different spatial and temporal scales. Nevertheless, in Mexico (as in many countries of the Latin American and the Caribbean Region), a lack of studies on SEW is constantly reported in high‐impact journals. We argue that this lack is mainly due to the language in which the majority of the scientific research about SEW in Mexico is published, which is Spanish. Therefore, the objective is to identify the main trends in SEW research in Mexico, through a review of peer‐reviewed studies published in Spanish. The review is centred on two sources of studies published in Spanish that are relevant to Mexican soil sciences communities: Scielo (Scientific Electronic Library Online) and Redalyc (Diamond Open Access scientific journal network non‐commercial global infrastructure owned by academia). As a result, we identified 37 relevant peer‐reviewed articles about SEW, and the principal article aim of these works is modelling and measuring SEW (45.9 and 29.7% of the total articles compiled, respectively). We observed that research on SEW in Mexico follows the same trends as global reports. For example, the most frequently implemented models are those in the Universal Soil Loss Equation and its variants. We observed no data‐sharing culture in most of the revised articles. Our results suggest that large‐scale studies on SEW are needed in Mexico to better understand its role in large‐scale earth system models. Therefore, we conclude that despite the scarce international visibility of Spanish‐written SEW research, multiple valuable studies have indeed been carried out and they provide relevant information for the development of baseline references towards enabling nationwide soil erosion monitoring programmes in Mexico.

“…First, during summer rainfall events, both rainfall and surface runoff play a crucial role in mobilizing sediment. Raindrop kinetic energy causes detachment of soil particles, and the resulting sediment is easily mobilized by surface runoff during the rainy season, along with additional sediment transported by the runoff (Wang et al, 2023). Such soil erosion processes lead to sheet and rill erosion, which mobilize sediment from the catchment surface (Wang et al, 2020; Zhang, 2023).…”

Differences in erosion patterns inevitably lead to different soil loss processes. However, the differences in sediment sources between rainfall and snowmelt erosion are not well studied. To address this gap, a study was conducted in a small agricultural catchment (3.5 km2) using the fingerprinting technique to quantify the various sources contributing to sediment, as well as determine the magnitude of sediment total nitrogen (TN), total phosphorus (TP), total potassium (TK) and soil organic matter (SOM) loads from three sources (cultivated land, unpaved roads and gullies) during the rainy season and spring thawing period. Sediment sources from 17 rainfall erosion and seven snowmelt erosion events of varying magnitudes were compared. The Collins and Bayesian mixing models, coupled with geochemical tracers (Cs, V, Cd, Pb and Ag), were applied to assess the contribution proportion of individual sediment sources to suspended sediment. According to the results obtained from the Bayesian mixing model with higher accuracy, cultivated land, unpaved roads and gullies contributed 60.3% (load‐weighted mean contribution [LMC] = 82.8%), 11.0% (LMC = 6.5%) and 28.7% (LMC = 10.7%) of the sediment in the rainy season, respectively. Cultivated land was the dominant sediment source for rainfall erosion, with high rainfall erosivity and sediment concentration. However, for snowmelt erosion, gullies were the primary sediment source (LMC = 66.2%), followed by cultivated land (LMC = 19.8%) and unpaved roads (load‐weighted = 14.0%). Meanwhile, in the spring thawing period, the contributions of unpaved roads to sediment were higher than in the rainy season. During the rainy season, the greatest contributions of TN, TP, TK and SOM were observed from cultivated land, with respective LMC values of 94.2%, 89.4%, 81.1% and 94.8%. With the increase of sediment contribution from gullies in the spring thawing period, its LMC of TN, TP, TK and SOM increased to 42.6%, 58.3%, 65.0% and 38.0%, respectively. The results of the study could be useful for understanding the processes of soil erosion, clarifying the driving mechanism of compound erosion, developing the compound erosion prediction model and optimizing the spatial configuration of erosion control measures.

“…While positive correlation between antecedent soil moisture and soil erosion or runoff generation has been reported [26,27], there are studies suggest otherwise. For instance, Castillo et al (2003) [28] conducted study in eastern Spain using Time Domain Reflectometry (TDR) in three semiarid small watersheds with different characteristics of vegetation to study the correlation between antecedent soil moisture and surface runoff.…”

The impact of antecedent soil moisture content on soil erosion is a complicated phenomenon, which is still under argument with contradictions in research results. Hence, the objective of this study is to investigate the impact of antecedent soil moisture content to soil loss on clay soil by conducting two-year field experiments under natural rainfall on runoff plots with length of 10 meters, width of 3 meters, and uniform slope of 9%. Volumetric soil moisture sensors were used to log soil moisture changes, and soil moisture readings were used along with rainfall records to quantify the antecedent soil moisture conditions for each rainfall event. Results of this study show duration of the effective erosion event outranks the antecedent volumetric soil moisture content. Field study also suggests that accumulative rain falling within 48 hours (Pp48) prior to an effective erosion event strongly correlated with soil loss per Rainfall-Runoff Erosivity Index (Soil Loss / EI30), particularly when the duration of an effective erosion event is either between 3 ~ 7 hours or 10~ 30 hours. Hence, Pp48 can be considered as an alternative to replace antecedent soil moisture content in RUSLE 2’s cover and management factor.
