Abstract. Climatic variability can considerably affect catchment-scale root zone storage capacity (Sumax), which is a critical factor regulating latent heat fluxes and thus the moisture exchange between land atmosphere as well hydrological response biogeochemical processes in terrestrial systems. However, direct quantification of changes Sumax over long time periods mechanistic drivers thereof at catchment scale are missing so far. As consequence, it remains unclear how climatic variability, such precipitation regime or canopy water demand, affects fluctuations may influence partitioning therefore also scale. Based on long-term daily records (1953–2022) upper Neckar River basin Germany, we found that hydro-climatic conditions, with an aridity index IA (i.e. EP/P) ranging ∼ 0.9 1.1 multiple consecutive 20-year periods, was accompanied by deviations ΔIE −0.02 0.01 from expected IE inferred parametric Budyko curve. Similarly, Sumax, 95 115 mm 20 %, were observed same period. While uncorrelated mean potential evaporation, shown magnitude controlled ratio winter to summer (p < 0.05). In other words, study region does not depend overall wetness condition for example expressed IA, but rather supply distributed year. be ΔIE. Consequently, replacing average, time-invariant estimate time-variable, dynamically changing formulation parameter model did result improved representation fluxes, (and thereof), shorter-term dynamics. Overall, this provides quantitative evidence significantly decades, reflecting vegetation adaptation variability. temporal evolution cannot explain heat) curve different conditions. have any significant effects characteristics catchment.

Root zone in the Earth system

Abstract. The root zone is a vital part of the Earth system and key element in hydrology, ecology, agronomy, land surface processes. However, its definition varies across disciplines, creating barriers to interdisciplinary understanding. Moreover, characterizing challenging due lack consensus on definitions, estimation methods, their merits limitations. This opinion paper provides holistic from hydrology perspective, including moisture storage, deficit, storage capacity. We demonstrate that plays critical role biosphere, pedosphere, rhizosphere, lithosphere, atmosphere, cryosphere system. underscore limitations traditional reductionist approach modelling this complex dynamic advocate for shift towards holistic, ecosystem-centred approach. argue offers more systematic, simple, dynamic, scalable, observable way describe predict science.

Vegetation Response to Climatic Variability: Implications for Root Zone Storage and Streamflow Predictions

Published: Feb. 26, 2024

Abstract. This paper investigates the influence of multi-decadal climatic variability on temporal evolution root zone storage capacities (Sr,max) and its implications for streamflow predictions at catchment scale. Through a comprehensive analysis 286 catchments across Europe US, we analyse deviations in evaporative ratios (IE) from expected values based aridity (IA) their subsequent impact Sr,max predictions. Our findings reveal that while do not strictly adhere to specific parametric Budyko curves over time, IE are generally very minor, with an average ΔIE = 0.01 interquartile range IQR= -0.01 0.03. Consequently, these minor lead limited changes Sr,max, mostly ranging between -10.5 +21.5 mm (-5.1 % +9.9 %). When uncertainties incorporated into hydrological models, is found be marginal, most significant shifts monthly evaporation exceeding 4 12 %, respectively. study underscores utility Budyko-style equations first order estimates future even face climate change variability. research contributes more nuanced understanding responses changing conditions offers valuable insights studies hydrology.

Catchment response to climatic variability: implications for root zone storage and streamflow predictions

Hydrology and earth system sciences, Journal Year: 2024, Volume and Issue: 28(20), P. 4577 - 4597

Abstract. This paper investigates the influence of multi-decadal climatic variability on temporal evolution root zone storage capacities (Sr,max) and its implications for streamflow predictions in Meuse basin. Through a comprehensive analysis 286 catchments across Europe US that are hydro-climatically comparable to basin, we construct inter-decadal distributions past deviations evaporative ratios (IE) from expected values based catchment aridity (IA). These ΔIE were then used estimate changes Sr,max quantify associated consequences Our findings reveal that, while do not strictly adhere their specific parametric Budyko curves over time, IE generally very minor, with an average ΔIE=0.01 interquartile range (IQR) −0.01 0.03. Consequently, these minor lead limited Sr,max, mostly ranging between −10 +21 mm (−5 % +10 %). When (ΔSr,max) accounted hydrological models, impact basin is found be marginal, most significant shifts monthly evaporation exceeding 4 12 %, respectively. study underscores utility Budyko-style equations first-order estimates future even face climate change variability. research contributes more nuanced understanding responses changing conditions offers valuable insights studies hydrology.
