Precipitation is the primary driver of hydrological models, and its spatial and temporal variability have a great impact on water partitioning. However, in data‐sparse regions, uncertainty in precipitation estimates is high and the sensitivity of water partitioning to this uncertainty is unknown. This is a particular challenge in drylands (semi‐ari...
Seasonal rainfall forecasts support early preparedness. These forecasts are typically disseminated at Regional Climate Outlook Forums (RCOFs), in the form of seasonal tercile probability categories—above normal, normal, below normal. However, these categories cannot be related directly to impacts on terrestrial water stores within catchments, since...
Drought is a persistent hazard that impacts the environment, people's livelihoods, access to education and food security. Adaptation choices made by people can influence the propagation of this drought hazard. However, few drought models incorporate adaptive behavior and feedbacks between adaptations and drought. In this research, we present a dyna...
Dryland regions are characterised by water scarcity and are facing major challenges under climate change. One difficulty is anticipating how rainfall will be partitioned into evaporative losses, groundwater, soil moisture, and runoff (the water balance) in the future, which has important implications for water resources and dryland ecosystems. Howe...
Challenges exist for assessing the impacts of climate and climate change on the hydrological cycle on local and regional scales, and in turn on water resources, food, energy, and natural hazards. Potential evapotranspiration (PET) represents atmospheric demand for water, which is required at high spatial and temporal resolutions to compute actual e...

Transmission losses from the beds of ephemeral streams are thought to be a widespread mechanism of groundwater recharge in arid and semi‐arid regions and support a range of dryland hydro‐ecology. Dryland areas cover ~40% of the Earth's land surface and groundwater resources are often the main source of freshwater. It is commonly assumed that where...
Future energy development relies on the use of alternative energy sources such as exploitation of deep geothermal energy from Hot Dry Rock (HDR). HDR reservoirs are considered strategical because of the great amounts of heat stored in deep basement. Here, a numerical model considering a discrete fracture network and data from the Soultz-Sous-Forets...
Nowadays, there has been increasing interest in topics related to education on soil science, however, topics about learning on this science have been poorly studied, particularly the relationship between learning styles and academic performance has not yet been addressed in the literature. this study aimed to understand the different student learni...
Six methods of completing missing data were evaluated: This is: q ratio, distance reasons, average neighbors, linear regression, weighted inverse distance (IDW) and regional vector method (MVR) in order to know its applicability in the Sub-basin of the Patate River (SRP). The analysis was carried out every month and
comprised a period between 1995-...
RESUMEN
El modelo Mecanicista Basado en Datos (DBM) se ha utilizado conjuntamente con el filtro de Kalman (como una técnica de asimilación de datos) para la predicción de caudales en una subcuenca ubicada en la parte alta de la cuenca del río Paute. Los resultados sugieren que el modelo DBM, conjuntamente con la técnica de asimilación de datos emp...
A Data-Based Mechanistic (DBM) model and the Nedbor-Afstromnings Model (NAM) were applied to simulate the rainfall-runoff relationship of two Andean basins, different in size, located in southern Ecuador. This article provides a comparative analysis of both modeling approaches, with emphasis on the evaluation of the model performance. The study rev...
