Weather Hydrologic Outlook (2024)

FAQs

Weather Hydrologic Outlook? ›

A hydrologic outlook is issued to provide notice of noteworthy rises on area rivers, but when the details are uncertain. River flooding and ice jams may be possible but there is low confidence in the timing, location, or extent.

A hydrologic warning, or outlook, is issued when a flood or other water-related disaster is predicted. It could be heavy rainfall that leads to flooding or an event that disrupts the natural hydrologic cycle.

Hydrologic disasters are those events that are caused by an alteration to the hydrologic cycle that result in significant loss of life, property, or damage to the environment. An alteration of the hydrologic cycle is a change in the normal hydrology of a watershed through natural or man-made means.

Hydrologic Warning is the ability to warn of imminent danger to life, property, and the environment from hydrologic disasters through the use of automated remote data collection networks, modeling and analyses, and integrated hazard communication.

When a hydrologic system is deemed "predictable", hydrologic predictions can be developed using a wide range of models that accept measurements of current conditions, and forecast of future conditions as input and project the future state of the hydrologic system and its response to these forcing variables.

Hydrologic Outlook

Issued when a flood potential exists in a time beyond 48 hours from the start of the event.

A hazard caused by the occurrence, movement, and distribution of surface and subsurface freshwater and saltwater. IRDR. Flood.

Floods are generally regarded as the most significant of hydrologic hazards, with losses amounting to over $2.5 billion in direct damages and nearly 100 lives lost annually (FIFMTF, 1992).

Hydrological disasters are the most violent climate change which impacts the environment and life of people. This article included the types of hydrological disasters such as floods, limnic eruptions, and Tsunami.

: the series of conditions through which water naturally passes from water vapor in the air to being deposited (as by rain or snow) on earth's surface and finally back into the air especially as a result of evaporation.

What type of hazard is hydrologic? ›

Hydrological hazards, or 'hydro-hazards', are defined as extreme events associated with the occurrence, movement and distribution of water, such as floods and droughts. Hydro-hazards usually result from a combination of compounding interacting physical processes that occur across multiple spatial and temporal scales.

1.2 Hydrologic Condition of Concern (HCOC)

G) indicate that an HCOC exists when a site's hydrologic regime is altered and there are significant impacts on downstream stream channels and aquatic habitats, alone or in conjunction with impacts of other projects.

Hydrologic condition analysis results in an understanding of the interrelationships among meteorological, surface- and ground-water, and physical and biological factors that influence the flow, quality, and/or timing of water. The magnitude, direction, and rate of change are the expression of hydrologic condition.

Outlook. A hydrologic outlook is issued to provide notice of noteworthy rises on area rivers, but when the details are uncertain. River flooding and ice jams may be possible but there is low confidence in the timing, location, or extent.

The adjective hydrologic comes from hydrology, "the science of water," and its roots, the Greek hyrdo-, "water," and the scientific suffix -logy, "study or science." The way water moves from the ocean to the atmosphere and back to the earth is known as the hydrologic cycle.

The hydrologic time scale τ of a stream site represents the ratio of total water delivered to flow variability, and governs the rate of delivery of runoff to a particular site.

A hydrologic outlook is a crucial component of weather forecasting that is often overlooked. The primary purpose of this outlook is to inform the public about potential water-related disasters, such as floods or heavy rainfall events, which may cause widespread disruption in the affected areas.

Hydrological conditions determine the distribution of plant species in wetlands, where conditions such as water depth and hydrological fluctuations are expected to affect the interspecific interactions among emergent wetland species.

Hydroclimate is the scientific field that brings together hydrology and climate, including the impacts that water and its processes have on Earth's climate, and the impacts of climate patterns and change on the global hydrological (or water) cycle.
