Abstract. Investigation was made on the climate change signal for hydrometeorological and hydrological variables along Paute River basin, in southern Ecuador Andes. An adjusted quantile perturbation approach used downscaling, impact of runoff studied two nested catchments within basin. The analysis done making use long daily series seven representative rainfall temperature sites study area considering signals global regional models IPCC SRES scenarios A1B, A2 B1. determination carried out...
Abstract. Andean headwater catchments are an important source of freshwater for downstream water users. However, few long-term studies exist on the relative importance climate change and direct anthropogenic perturbations flow regimes in these catchments. In this paper, we assess streamflow based long time series hydrometeorological data (1974–2008) land cover reconstructions (1963–2009) Pangor catchment (282 km2) located tropical Andes. Three main trajectories can be distinguished during...
This study evaluates the pollutant removal efficiency of two decentralized wastewater treatment plants (WWTPs), Acchayacu and Churuguzo, located in southern Andes Ecuador. Until 2021, worked with an upflow anaerobic filter (UAF), after which it transitioned to vertical subsurface flow constructed wetlands (VSSF-CW). In contrast, Churuguzo employs surface (SF-CW). Key parameters such as five-day biochemical oxygen demand (BOD5), chemical (COD), total phosphorus, organic nitrogen, ammonia...
An intercomparison of different approaches for the construction and calibration lumped conceptual rainfall-runoff models is made based on two case studies with unrelated meteorological hydrological characteristics located in regions, Belgium Kenya. While a model pre-fixed "one-size-fits-all" structure traditionally used modeling, this paper shows advantages inference from data or field evidence case-specific step-wise way using non-commensurable measures derived observed series. The...
Abstract. Andean headwater catchments play a pivotal role to supply fresh water for downstream users. However, few long-term studies exist on the relative importance of climate change and direct anthropogenic perturbations flow regimes. In this paper, we assess multi-decadal in freshwater provision based long time series (1974–2008) hydrometeorological data land cover reconstructions 282 km2 catchment located tropical Andes. Three main trajectories can be distinguished: (1) rapid decline...
Se presenta la metodología diseñada para el seguimiento geomorfológico del derribo de azudes, así como los resultados obtenidos hasta momento en dos casos concretos: las presas Mendaraz (río Urumea) e Inturia Leitzaran) Gipuzkoa. han realizado secciones transversales, abundantes mediciones procesos sobre testigos, análisis nuevos depósitos generados y muestreos granulométricos morfométricos. En caso se registrado rápidas movilizaciones sedimentos importantes cambios geomorfológicos aguas...

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...
Characterization of climate variability in the Andes mountain range needs special assessment as rainfall and temperature are extremely variable space time. This paper examines anomalies observed month data respectively 25 16 stations, from early 1960‟s to 1990‟s compare them against different external influences annual 3-month seasonal block periods. The stations located Río Paute Basin Ecuador‟s southern Andes. All within elevation band 1800 4200 m a.s.l. affected by Tropical Pacific,...
Several cities in developing countries are challenging the permanent process of urbanization. This generates a great disturbance on hydrological response urbanized area during rainfall events, which can cause floods. Among disturbances that basins may suffer, it is found variations rain losses (hydrological abstractions) be estimated by named volumetric runoff coefficient (CVOL) methodology. In present study, this methodology used an attempt to estimate abstraction two nearby basins, with...
