Climate change presents significant global challenges and is a top priority for many countries, including Vietnam, in achieving sustainable development goals. Teachers’ perceptions of climate strongly influence their teaching ability to inspire students take actions. This study examines the knowledge, attitudes, beliefs, intentions Vietnamese pre-service teachers regarding through survey 468 participants from teacher education institutions nationwide. Research findings reveal that while have...

Abstract Almost every year, Vietnam suffers floods resulting in the loss of many lives and considerable costs for damaged lost properties. This study proposes a forecasting system that couples dynamical downscaling technique with hydrologic models to forecast real-time flood events lead time ranging from one three days. approach is demonstrated by applying regional numerical weather prediction physically based model Thanh My Nong Son watersheds. System inputs are provided two global NWPs,...

Effect of climate change on hydrologic flow regimes, particularly extreme events, necessitates modeling future flows in order to best inform water resources management. This study simulated the Cache Creek watershed California over 21st century using a hydro-climate model (Watershed Environmental Hydrology Hydro-Climate Model; WEHY-HCM) forced by projections. The projections, based four emission scenarios two global models (GCMs), fifth-generation atmospheric and third-generation community...

It is important to assess the reliability of high-resolution climate variables used as input hydrologic models. High-resolution data often obtained through downscaling Global Climate Models and/or historical reanalysis, depending on application. In this study, performance dynamically downscaled precipitation from National Centers for Environmental Prediction (NCEP) and Center Atmospheric Research (NCAR) reanalysis (NCEP/NCAR I) was evaluated at point scale, watershed regional scale against...

Long-term water supply data are important for the current practice of resources management at a target region. However, long-term outflow from reservoirs typically limited fine time resolution (hourly). In this study, historical on Shasta Dam were reconstructed by reservoir operation model with inflow data. Before embarking exercise, first means watershed environmental hydrology hydroclimate model, its input provided atmospheric reanalysis The used in study National Center Atmospheric...

The risk of more frequent and intensified extreme events is expected to increase with climate change. In semi-arid regions, particularly, both increased flooding prolonged droughts pose a threat as the water resources system must be prepared for types extremes. To understand how future extremes may altered, however, past understood. For this reason, study employs three physically based models simulate atmospheric, snow, hydrologic conditions in American River Watershed: Weather Research...

In this study several issues with the standard flood frequency analysis are discussed in context of a changing hydro-climate 21st century. Among these loss statistical equilibrium studied region during century has serious implications on that is some detail. An alternative method to within framework climate based ensemble future projections reported and demonstrated by numerical application target watershed.

In snow-dominated regions surface air temperature is expected to have a substantial effect on the magnitude of flood during storm event. It risky estimate design based only maximum precipitation while excluding other atmospheric variables like and radiation. To overcome this problem, methodology proposed physically hydrologic model with input from maximized events by means numerical model. As case study, probable floods are simulated for Upper Feather River watershed, Yuba American watershed...

Abstract Estimation of the extreme precipitation over a target watershed under changing climate would be necessary to design safe large hydraulic structures. For this purpose, maximum (MP) estimation approach was applied American River Watershed (ARW) in Northern California several future conditions 90 water years (2010–2099). These were obtained using 13 projections from two general circulation models (ECHAM5 and CCSM3) based on four scenarios (Special Report Emissions Scenarios: A1B, A1FI,...

Abstract Estimation of probable maximum flood (PMF) is a crucial process in water resources management and the design large hydraulic structures. However, there are uncertainties estimation hydrologic conditions that contribute to extreme floods. In particular, this case snow‐dominated regions, as surface air temperature wind speed understood have substantial effect on magnitude during storm event. Motivated by development new approach investigate estimate reliable PMF values an attempt...

Abstract Long-term, high spatial and temporal resolution atmospheric hydrologic data are crucial for water resource management. However, reliable high-quality precipitation not available in various regions around the world. This is, particular, case transboundary regions, which have no formal sharing agreement among countries. study introduces an approach to construct long-term high-resolution extreme 72 h hillslope flood maps over a tropical region by coupled physical hydroclimate WEHY-WRF...

Abstract Snow is an important component of the Earth's climate system and particularly vulnerable to global warming. It has been suggested that warmer temperatures may cause significant declines in snow water content cover duration. In this study, snowfall snowmelt were projected by means a regional model was coupled physically based over Shasta Dam watershed assess changes duration during 21st century. This requires both physical data future projections. These include topography, soils,...

Estimated extreme precipitation and floods provide crucial information for both the design of large hydraulic structures water resources management. This study aims to estimate, in a series numerical experiments, probable maximum associated with rain events over seven watersheds central/southern Sierra Nevada. To this end, total 249 72-h rainfall events, extracted from historical reconstructions 1852 2014, were maximized by means atmospheric boundary condition shifting (ABCS) method...
