Meteorological Observationsost widely used, other parameters of interest include air temperatures, humidity, solar radiation and wind speeds. Rainfall measurement techniques include raingauges and weather radar, with satellite precipitation estimates playing an increasingly important role, particularly in data-sparse regions.角斗士 发表于 2025-3-28 22:02:05

Meteorological Forecasting weather forecasts provided to the public, more specialised products and services are usually available to expert users, including the raw ensemble model outputs for use in flow forecasting models. The main meteorological forecasting techniques consist of nowcasting, Numerical Weather Prediction modPermanent 发表于 2025-3-29 06:14:56
Hydrological Forecastingceptual rainfall-runoff models are the most widely used in real-time forecasting, but physically based and data-driven models have an important role too, along with flow routing techniques encompassing both hydrological and hydrodynamic approaches. Ensemble and probabilistic techniques are increasinOMIT 发表于 2025-3-29 07:46:30
Demand Forecastings returned to the river system, whilst consumptive use represents a more permanent loss. Water demands are typically estimated by aggregating the water demands of individual users such as households, factories and irrigation schemes or using regression relationships, econometric approaches and artifadj忧郁的 发表于 2025-3-29 14:24:19

Flood Forecastingency responders more time to take action. Typical forecasting techniques include rainfall-runoff, flow routing and hydrodynamic models and simpler empirical approaches such as level-to-level correlations. Data-driven and machine learning techniques are increasingly used too. Models are usually operaFLIP 发表于 2025-3-29 22:28:52

Drought Early Warning Systemsnges include the slow onset and wide spatial variability of events and the huge choice of possible criteria for issuing alerts. More recently, flash droughts have been recognized as another type of threat. Drought forecasting approaches range from simple empirical techniques through to integrated ca
