In Algeria, only the transport of suspended sediment is measured, rate bedload in global solids estimated, approximately. Measures bed load field are very costly, due to flow disturbances. As a result, evaluations this type difficult carry out absence databases. article, we tried quantify mode at wadi El-Hammam using formula Meyer-Peter and Müller. Formula that seems best adapted physical chara...

Abstract In this study, the artificial neural network (ANN) method was applied to investigate impacts of climate change on water quantity and quality Qu'Appelle River in Saskatchewan, Canada. First, second-generation Canadian earth system model (CanESM2) adopted predict future conditions. The Statistical DownScaling Model (SDSM) then downscale generated data. To analyze river, concentrations di...

Purpose: to assess the state and operating conditions of fish passage channels Ust-Manych waterworks on river Western Manych. Materials methods. The factual basis for assessing was materials author’s survey field studies performed at given facility in 2022. were carried out according generally accepted methods conducting hydrometric measurements flow rate parameters geometric dimensions network...

Abstract. An integrated modeling approach for forecasting flood events is presented in the current study. advanced model, which based on coupling of hydrological and atmospheric components, was used a twofold objective: first to investigate potential coupled hydrometeorological model be at two medium-size drainage basins area Attica (Greece) second influence use precipitation forecast skill. Fo...

Introduction: Mexico uses hydrological models to determine floods, evaluate land use change scenarios, climate and define federal zones, among other applications. However, the are rarely calibrated beforehand, which increases uncertainty in design of structures hydraulic standards. Objective: To build a model for watershed Fuerte River, Mexico, extreme rainfall events occurred 2009, 2011, 2015,...

The Assiniboine River Basin (ARB) is subject to an exceptionally variable precipitation regime of the Canadian Prairies, ranging between record droughts and unprecedented flooding in just past decade. To assess impact a changing climate on hydroclimate variability ARB, we used bias–corrected simulations from Regional Climate Model (CanRCM4) drive MESH model for two 60–year periods, historical b...

Nitrogen (N) and phosphorus (P) are the most limiting nutrients in natural freshwater wetlands. Flooded marshes dominate wetlands of Lower Paraná River floodplain (Argentina). The leaf N P concentration N:P ratios were assessed as a first approach to evaluate nature nutrient limitation. A total 96 sites 131 dominant plant populations (belonging 50 herbaceous macrophyte species) sampled medium h...

Abstract. In cities around the world, urban green spaces provide a range of benefits and ecosystem services. However, recent years have shown how prolonged warm dry periods can affect water resources lead to stress in vegetation spaces, even temperate regions. Consequently, quantitative knowledge about ecohydrological partitioning different types space is crucial for balancing sustainable needs...
