“…According to Návar [40], semidry ecosystems present a higher percentage of losses due to interception than other types of ecosystems. Similarly, other studies in dry ecosystems have reported that approximately 35% of total precipitation is lost by interception [41,42]. High interception leads to low moisture values, as reported by Zhu et al [11] in a similar study from a Picea crassifolia Kom.…”

“…Nonetheless, interception could be negligible during large rainfall events, and this explains the similar response among micro-catchments during events higher than 30 mm. Studies in other ecosystems have found interception was between 30% and 74% when precipitation and rainfall intensity was below 20 mm and 15 mm h −1 , respectively; but the interception decreased to between 10% and 20% for storms above those thresholds [42].…”

Understanding soil moisture behavior in semi-dry forests is essential for evaluating the impact of forest management on water availability. The objective of the study was to analyze soil moisture based in storm observations in three micro-catchments (0.19, 0.20, and 0.27 ha) with similar tree densities, and subject to different thinning intensities in a semi-dry forest in Chihuahua, Mexico. Vegetation, soil characteristics, precipitation, and volumetric water content were measured before thinning (2018), and after 0%, 40%, and 80% thinning for each micro-catchment (2019). Soil moisture was low and relatively similar among the three micro-catchments in 2018 (mean = 8.5%), and only large rainfall events (>30 mm) increased soil moisture significantly (29–52%). After thinning, soil moisture was higher and significantly different among the micro-catchments only during small rainfall events (<10 mm), while a difference was not noted during large events. The difference before–after during small rainfall events was not significant for the control (0% thinning); whereas 40% and 80% thinning increased soil moisture significantly by 40% and 53%, respectively. Knowledge of the response of soil moisture as a result of thinning and rainfall characteristics has important implications, especially for evaluating the impact of forest management on water availability.

How Is the Intensity of Rainfall Events Best Characterised? A Brief Critical Review and Proposed New Rainfall Intensity Index for Application in the Study of Landsurface Processes

In many studies of landsurface processes, the intensity of rainfall events is expressed with clock-period indexes such as I30, the wettest 30-minute interval within a rainfall event. Problematically, the value of I30 cannot be estimated for rainfall events shorter than 30 min, excluding many intense convective storms. Further, it represents a diminishing proportion of increasingly long rainfall events, declining to <2% of the duration of a 30-hour event but representing 25% of the duration of a two-hour event. Here, a new index termed EDf5 is proposed: It is the rainfall depth in the wettest 5% of the event duration. This can be derived for events of any duration. Exploratory determinations of EDf5 are presented for two Australian locations with contrasting rainfall climatologies—one arid and one wet tropical. The I30 index was similar at both sites (7.7 and 7.9 mm h−1) and was unable to differentiate between them. In contrast, EDf5 at the arid site was 7.4 mm h−1, whilst at the wet tropical site, it was 3.8 mm h−1. Thus, the EDf5 index indicated a greater concentration of rain at the arid site where convective storms occurred (i.e., the intensity sustained for 5% of event duration at that site is higher). The EDf5 index can be applied to short, intense events that can readily be included in the analysis of event-based rainfall intensity. I30 therefore appears to offer less discriminatory power and consequently may be of less value in the investigation of rainfall characteristics that drive many important landsurface processes.

“…Canopy interception is the amount of rainfall intercepted by plant canopy and then evaporates back to the atmosphere as rainfall loss, generally defined as the difference between gross rainfall and net rainfall (i.e., throughfall and stemflow) (Livesley, Baudinette, & Glover, 2014; Zhang et al, 2017). Canopy interception in the semiarid areas can account for 6.9% to 27.2% of the total rainfall, and the values tend to be higher in arid regions (Brasil, Andrade, Palácio, Medeiros, & Santos, 2018). Interception loss is one of most essential alterations in hydrological fluxes resulting from vegetation growth and succession and has various ecological and hydrological impacts.…”

Aboveground biomass production and dominant species type determined canopy storage capacity of abandoned grassland communities on semiarid Loess Plateau

et al. 2020

Quantifying canopy storage capacity and its temporal variation is necessary for evaluating the ecohydrological effects of grassland restoration. In this study, four grassland communities after abandonment of 2, 7, 15 and 30 years on the semiarid Loess Plateau were selected, and canopy storage capacities, canopy structures and species compositions were examined in the growth period (May to September). Canopy, living plant, standing litter and floor litter storage capacities ranged from 0.11–0.56, 0.030–0.51, 0.0070–0.079 and 0.013–0.21 mm, respectively, and all exhibited an increasing trend with restoration year. Canopy storage capacity, vegetation coverage and aboveground biomass reached the maximum in August. Standing and floor litter storage capacities had the highest correlations with their biomass weights. Species diversity reached the maximum in 15 years abandoned grassland, with no significant monthly change. Annual forb, annual grass, perennial forb and perennial forb/grass were the typical dominant species type of 2, 7, 15 and 30 years abandoned grasslands, respectively. Perennial forbs (Artemisia gmelinii, Lespedeza davurica) had higher water storage than those of annual forb (Artemisia capillaris) and grasses (Setaria viridis, Roegneria kamoji). Path analysis revealed that fresh aboveground biomass and dominant species type mainly affected canopy storage capacity. No significant correlations were found between storage capacity and species diversity indexes. These results highlighted the importance of vegetation aboveground biomass and species functional group for evaluating grassland hydrological function and adopting suitable restoration strategy.
