Social pressure on alluvial plains and deltas is large, both from an economic point of view and from a nature conservation point of view. Gradually, flood risks increase with economic development, because the expected damage increases, and with higher dikes, because the flooding depth increases. Global change, changing social desires, but also changing views, require a revision of flood-risk ma...
MESSENGER observations from Mercury orbit reveal that a large contiguous expanse of smooth plains covers much of Mercury's high northern latitudes and occupies more than 6% of the planet's surface area. These plains are smooth, embay other landforms, are distinct in color, show several flow features, and partially or completely bury impact craters, the sizes of which indicate plains thicknesses...
Past decades damage by floods in Iran and on the other of the world has shown that we have still much work to do to cope with this problem. Hence, the study of these events and development of more effective adaptation and mitigation policies has become a priority, in other parts of the globe. First step in achieving flood risk assessment is data collection. Availability, suitability and quality...
Inadequate productivity and over-capacity of land in many watersheds and plains of the country, has increased flooding potential. Therefore, reducing flood damage with the participation of both policymakers and the public as key stakeholders in decision-making, planning, long-term management and foresight in decisions are unavoidable. In the present study, SWOT analytical method was used to ...
Laser altimetry by the MESSENGER spacecraft has yielded a topographic model of the northern hemisphere of Mercury. The dynamic range of elevations is considerably smaller than those of Mars or the Moon. The most prominent feature is an extensive lowland at high northern latitudes that hosts the volcanic northern plains. Within this lowland is a broad topographic rise that experienced uplift aft...
The basis of spatial planning is the geomorphological zoning of ground surface, in which the first phase is determining the homogeneous zones of the ground surface in terms of geomorphological characteristics. The current study aimed at determining the proper zones for artificial feeding in Gahar mountainous region and Garebayegan plains in Fars province by the use of zoning the ground by Evans...
An important aspect of hydraulic flood modelling deals with representing topography of river and floodplain. Commonly, flood model applications are reported successful in topographically simple areas were topography only changes gradually and where topography is simulated by DEM’s of relatively low resolution. Such DEM’s are particular useful for flood simulation in rural areas, although import...
1 THE PLACE OF TREATMENT IN AN ANTIMALARIAL CAMPAIGN By W. B. McQUEEN, M3, ch.B. (Glasgow) d.t.m. (Liverpool) Introduction The practice with which this paper deals is situated in Upper Assam, near the North Eastern Frontier, and comprises ten tea gardens owned by five companies, one company having five gardens, one company two, and three companies one each. The district is bisected by a river, ...
meanders are among the important characteristics of some rivers that flow in semi-arid regions. swift displacement along the river's flow, change in the location of the central ridge and bank erosion leateral erosion are resulted from making meander in the river's flow. meanders in river courses on north east slopes of sahand (located in 46ë 43ì to 47ë 15ì e and from 36ë 05ììì...
