Abstract Cold regions provide water resources for half the global population yet face rapid change. Their hydrology is dominated by snow, ice and frozen soils, climate warming having profound effects. Hydrological models have a key role in predicting changing but are challenged cold regions. Ground‐based data to quantify meteorological forcing constrain model parameterization limited, while hydrological processes complex, often controlled phase change energetics. River flows impacted poorly...
Abstract. The snowpack over the Mediterranean mountains constitutes a key water resource for downstream populations. However, its dynamics have not been studied in detail yet many areas, mostly because of scarcity observations. In this work, we present characterization two mountain ranges Lebanon. To obtain necessary information, developed 1 km regional-scale snow reanalysis (ICAR_assim) covering period 2010–2017. ICAR_assim was by means an ensemble-based data assimilation Moderate...
The Middle East and North Africa (MENA) can be considered as the most water-scarce regions of world thus affecting status vegetation in this zone. Normalized Difference Vegetation Index (NDVI) datasets are used worldwide for large-area mapping monitoring. Time series analysis techniques to define, evaluate, monitor dynamics variability using up-to-date remote sensing datasets. This study assesses degradation Arab countries SPOT derived NDVI time data remotely sensed imageries period between...
State-of-the-art climate models project a substantial decline in precipitation for the Mediterranean region future1. Supporting this notion, several studies based on observed data spanning recent decades have suggested decrease precipitation2–4, with some attributing large fraction of change to anthropogenic influences3,5. Conversely, certain researchers underlined that exhibits considerable spatiotemporal variability driven by atmospheric circulation patterns6,7 maintaining stationarity...
Abstract. We present a unique meteorological and snow observational dataset in Mount Lebanon, mountainous region with Mediterranean climate, where snowmelt is an essential water resource. The study covers the recharge area of three karstic river basins (total 1092 km2 elevation up to 3088 m). consists (1) continuous height observations, (2) snowpack field measurements, (3) medium-resolution satellite cover data. measurements at automatic weather stations (MZA, 2296 m; LAQ, 1840 CED, 2834 m...
Abstract This paper presents the composite drought indicator (CDI) that Jordanian, Lebanese, Moroccan, and Tunisian government agencies now produce monthly to support operational management decision making, it describes their iterative co-development processes. The CDI is primarily intended monitor agricultural ecological on a seasonal time scale. It uses remote sensing modelled data inputs, reflects anomalies in precipitation, vegetation, soil moisture, evapotranspiration. Following...
Abstract. In many Mediterranean mountain regions, the seasonal snowpack is an essential yet poorly known water resource. Here, we examine, for first time, spatial distribution and evolution of snow equivalent (SWE) during three seasons (2013–2016) in coastal mountains Lebanon. We run SnowModel (Liston Elder, 2006a), a spatially distributed, process-based model, at 100 m resolution forced by new automatic weather station (AWS) data snow-dominated basins Mount evaluate recent upgrade liquid...

We present a comprehensive snow dataset for Mont-Lebanon. The includes continuous meteorological observations from three high elevation automatic weather stations (AWS), snowpack field measurements collected at 30 different courses (elevation range 1300-2900 m a.s.l.), and post-processed MODIS products.

A new method of participatory decision support that can be used in transboundary basins is presented. The framework this relies first on the creation a geographic information system database to store hydrologic data and allow easy access by stakeholders. Results show countries Jordan River could benefit from framework, case southern Lebanon six climate stations should replaced or reactivated. Finally, mechanism Lebanese presented shows an observation model will facilitate science policy integration.
