This lesson provides an overview of the primary influences of watershed and channel sedimentation. In a short narrated portion of the lesson, we explore a section of the Rio Grande watershed and channel in New Mexico using Google Earth imagery, river profiles, and graphic animations. We highlight features of the upland catchments, the river channel, and the Elephant Butte Reservoir. We then demonstrate how environmental factors (climate, geography, land use changes, reservoirs) impact the supply and movement of sediments for the Rio Grande and other rivers. The focus is on the three primary pr ...
SDS-WAS, 2015-001. Dust/ sand storms over Libya : Spatial distribution, frequency and seasonality, technical report
The climate of most of the coastal region of Libya can be classified as semi-arid, while that of the rest of the country is arid. Rainfall is erratic with extremely variable yearly rainfall amounts: a series of dry years may follow a year with adequate rainfall. Furthermore, monthly and seasonal totals are not homogenous and most precipitation occurs during winter months.
Dust and sand storms, the focus of the present study, are one of the main extreme weather phenomena that affect Libya. In this paper, spatial and temporal distribution, frequency and seasonality are studied and analyze ...
Flood Management Tool Series, Technical Document, 23. Health and Sanitation Aspects of Flood Management
Flood events are known for their profound capacity to positively or negatively affect humans. Floods improve overall human well-being by providing services such as groundwater recharge, surface-water replenishment, soil-fertility enhancement and a general increase in the value of social–ecological systems. Equally, however, flood events pose a series of diverse health threats, ranging from contaminated water sources to decreased agricultural productivity, especially when communities are vulnerable and lack the capacity to effectively respond to, and recover from, the adverse effects of floods. ...
Flood Management Tool Series, Technical Document, 22. The role of the media in flood management
Communication is the imparting or exchange of information between individuals or groups through a common system of symbols, signs or behaviour (Merriam-Webster, 2013a; Oxford Dictionaries, 2013). In recent decades, different conceptual models have been developed to explain the process of human communication. One of the best representations of the flow of information in flood communication is the Interactional Communication Model proposed by Schramm (Schramm, 1954).
Flood Management Tool Series, Technical Document, 21. Effectiveness of flood management measures
It is not enough to assert—to an elected official, a regulator, a donor organization or the taxpayer—that one’s organization is doing an effective job of flood management. One also has to be able to provide a credible answer to the question: “How do you know?” 2 There is a multiplicity of flood management activities that can be pursued by a plethora of government jurisdictions, government agencies, NGOs, private and volunteer groups— independently, in cooperation, in competition. These activities may include: constructing flood prevention infrastructure; rebuilding houses, buildings and infras ...Perceptions of obvious and disruptive climate change: community-based risk assessment for two native villages in Alaska: In Climate 2015, 3(4), pp. 812-832
This work operationalizes the determinants of climate change risk, exposure and vulnerability, through the perceptions held by Native hunters, fishers, and gatherers in Savoonga and Shaktoolik, Alaska. Informed by their skill, experience, and the traditional knowledge of their elders, hunters, fishers, and gatherers in these communities are astute observers of their environment and environmental change. A questionnaire is used to sort and rank their perceptions of the most obvious and disruptive elements of climate change as representations of exposure and vulnerability, respectively.Disaster risk programme to strengthen resilience in the dry corridor in Central America

Assessing Agricultural Risk in Africa Using Satellite Data and Land Surface Models
Droughts pose a major risk in most African countries including Ghana where agricultural activities are heavily dependent on rainfall. Efforts at assessing droughts and providing decision support tools to farmers are hampered by a lack of rainfall and other meteorological data over many parts of Africa. Satellite based rainfall measurements have been suggested to fill the rainfall data gaps over Africa to enable effective assessment of droughts. Traditional methods of assessing droughts have been based on statistical formulations that relied mostly on precipitation. This approach to assessing d ...ASEAN disaster management reference handbook
