Effectiveness of Institutional Flood Adaptation Actions and Plans in Vhembe District Municipality, South Africa
… rainfall, leading to floods, particularly in low-lying areas. This study, therefore analysed the perceived effectiveness of existing flood adaptation actions and plans used in response to flood disasters in Vhembe District Municipality and provide recommendations to enhance the effectiveness …

Flood risks and spatial vulnerabilities: a case study of the University of Venda, South Africa
… of Venda. The study's goals were as follows: (i) To determine the spatial vulnerability level of the University of Venda to flood risks; (ii) To highlight the spatial risks associated with flooding; and (iii) To recommend sustainable spatial planning coping strategies to reduce flood …

The Epidemiology and Control of Human Influenza in Vietnam
… in the north but no seasonal pattern observed in low lying areas of central and southern Viet Nam. Seasonality is however observed in the elevated provinces of central Viet Nam, suggesting that the seasonal patterns are driven by climate. Principal component analysis finds that temperature and …

Hereditary haematological disorders in the Greek population of Cape Town
… been demonstrated to occur more frequently in low-lying areas and places where malaria was endemic in the past. Population movement has made this situation less clearcut in recent times. Cape Town has a Greek population numbering approximately 5000 persons. As the thalassaemias, particularly, …

Climatic trends and soil moisture feedbacks over Zimbabwe
… of the 500hPa anticyclones and a decrease of low pressures. However, some high altitude stations showed an intensification of precipitation events. This would exacerbate need for proper planning of future water resource management and farming strategies. Soil moisture rainfall feedback …

Navigating Shared Vulnerabilities: Climate Adaptation on the Split Island of Saint Martin
… of the Caribbean Sea is a volcanic island whose low-lying areas are at high risk for flooding and storm surges as a result of exposure to increasing severe hurricanes that is compounded by sea level rise. Saint Martin’s mountainous landscape is split by two governments. The first is the …

Influence of site factors and vascular conductivity on the development of procerum root disease
… shoot elongation, reduced leaf conductance, low photosynthetic activity, low pre-dawn water potential and chlorosis of foliage. Resinous occlusion of the sapwood at the root collar is the likely cause of the suite of symptoms that resemble water stress. Increased incidence ofPRD has been …

Mineral Chemistry of Heavy Minerals in the Old Hickory Deposit, Sussex and Dinwiddie Counties, Virginia
… Carolina. The high density of heavy minerals allows for selective concentration during transport and deposition. Under the right conditions, placers of considerable size can be formed. The elliptically shaped ore body of the Old Hickory Deposit extends in a North - South direction and is …

An evaluation of soil and water management practices on a lowland soil with poor natural drainage
Low-lying areas of the Lower Fraser Valley tend to have poor natural soil drainage. Excess moisture, because of a high water table and ponded surface water, restricts the range of crops that can be grown and influences farm management decisions regarding the nature and timing of field operations. …

Effect of exposure on the erodibility of intertidal mudflats
Sediments on intertidal flats are exposed during low tides. Under the effect of exposure, the water content of sediments decreases because of the evaporation process, which alters the erosive behaviour of cohesive sediments, and therefore changes the patterns of erosion/accretion on intertidal …

Distributed surface-subsurface modelling approach for evaluating the impact of rain gardens on steep terrain
As the proportion of people living in urban low-lying areas increase dramatically over time, a large number of high and steep slopes have been modified in order to increase the available land cover. This expansion usually includes vegetation removal and construction of multiple engineered …

Coastal Erosion Hazard in Bangladesh: Space-time pattern analysis and empirical forecasting, impacts on land use/cover, and human risk perception
Coastal areas are vulnerable to different natural hazards, including hurricanes, cyclones, tsunami, floods, coastal erosion, and saltwater intrusion. These hazards cause extensive social, ecological, economic, and human losses. Continued climate change and sea-level rise is expected to …

Hydrometeorological Variability over Pakistan
… speed, potential evapotranspiration and river flow, especially during the summer season, represent a substantial change in the energy, mass and momentum fluxes that are facilitating the establishment of the Karakoram Anomaly. In turn, it is influencing the availability of glacier melt in River …

Development of national extent terrain attributes (TANZ), soil water balance surfaces (SWatBal), and environmental surfaces, and their application for spatial modelling of Pinus radiata productivity across New Zealand
… so great. Furthermore, regions of relatively low productivity may become increasingly desirable because these sites require lower capital outlay. In this research, a series of spatial surfaces potentially useful in the modelling and mapping of forest productivity across the national extent of …

Catastrophic Tsunamis In the Indonesian Archipelago
… with casualties of more than 2000 people, followed almost every two years with the 1994 East Java Tsunami, 1996 Tonggolobibi Sulawesi Tsunami, 1996 Biak Tsunamis, 1998 Papua New Guinea Tsunami, and the Banggai Tsunami in 2000. These represent the tsunami season for the eastern part of the …
