Abstract An initial ground validation of the Integrated Multisatellite Retrievals for GPM (IMERG) Day-1 product from March 2014 to August 2015 is presented tropical Andes. IMERG was evaluated along with Tropical Rainfall Measuring Mission (TRMM) Precipitation Analysis (TMPA) against 302 quality-controlled rain gauges across Ecuador and Peru. Detection, quantitative estimation statistics, probability distribution functions are calculated at different spatial (0.1°, 0.25°) temporal (1 h, 3...

Abstract Soil hydraulic properties control the provision of hydrological services. Vegetation and topography influence these by altering soil structure porosity. The underlying mechanisms are not yet fully understood for high Andean region. In this study, we examined how vegetation topographic attributes related to pore in young volcanic ash soils, further correlated them texture, organic carbon, root characteristics explain relationships. a 0.7 km 2 study site located páramo northern...

Abstract. Vegetation plays a key role in the hydrological and biogeochemical cycles. It can influence soil water fluxes transport, which are critical for chemical weathering development. In this study, we investigated balance solute two profiles with different vegetation types (cushion-forming plants vs. tussock grasses) high Ecuadorian Andes by measuring content, flux, concentrations modeling hydrology. We also analyzed of weathering. The on is restricted to A horizon. Evapotranspiration...

Abstract Traditional hydrometric data combined with environmental tracers such as water stable isotopes contributes to improve the understanding of catchment hydrology. Nevertheless, application isotopic in headwater catchments tropical Andes deep soils and permeable parent material influenced by recent volcanism remains limited. In this study, composition precipitation, soil water, wetlands, streamflow was studied provide insights into hydrology a small Andean volcanic soils, ash layers,...

Background We report the vegetation at 4050–4600 m in 1960 on western slopes of Antisana, Ecuador, decades before burning and grazing were prohibited. Aim: To provide a baseline against which new surveys could be compared to evaluate conservation efforts.Methods (a) ordinated grassland types derived communities using constancy values species typical stands, (b) recorded evidence community dynamics, (c) composition occupying smaller areas than grassy páramo, (d) inhibition facilitation other...

Soil moisture is a critical variable in the hydrological cycle and climate system, significantly impacting water resources, ecosystem functioning, occurrence of extreme events. However, soil data are often scarce, dynamics not fully understood mountainous regions such as tropical Andes Ecuador. This study aims to model predict using situ-collected hydrometeorological for training data-driven machine-learning techniques. Our results highlight fundamental role vegetation controlling...

The Topo River basin, located in the tropical region of Ecuador, is considered a little-known and well-preserved with limited access conditions scarce data that hinder its hydrological understanding. However, this gap can be addressed through study, which evaluates morphometric hydrometeorological factors, relating them to water storage basin comparing these results other watersheds. aim identify factors control variability storage. Firstly, characterization was conducted. Then, carried out...

Conservation and land use policies are key to regulating water in watersheds, influencing quantity, quality storage, mitigating risks such as erosion flooding. In Ecuador, the Socio Bosque Program (SBP), part of Good Living Development Plan (2013-2017), focused on conservation without fully considering benefits. To optimize its implementation, upper basin Coca River, relevant for hydroelectric potential, was evaluated by analyzing inclusion criteria SBP. Four scenarios cover change were...

<p>The Ecuadorian páramo, a neotropical ecosystem located in the upper Andes, acts as constant source of high-quality water. It also stores significant amounts C at regional scale. In this region, volcanic ash soils sustain most paramo, and storage results partly from their propensity to accumulate organic matter. Vegetation type is known influence balance between plant inputs soil losses, ultimately affecting (SOC) content stock. Tussock-forming grass (spp....

<p>The high tropical Andes ecosystem, known as páramo, provides important hydrological services to densely populated areas in the Andean region. In order manage these sustainably, it is crucial understand biotic and abiotic processes that control both water quality fluxes. Recent research páramo highlights a knowledge gap regarding role played by soil-vegetation interactions controlling soil-water resulting solute...

<p>Soils play a key role in the provision of vital ecosystem services. Soil functions, that deliver these services, are governed by soil properties.  structure is fundamental property soils since it controls water, geochemical and biological processes.  The pore system, one main components structure, can be affected different feedbacks. Vegetation have an impact on system through changes size distribution porosity, causing differences hydraulic...
