Natural and technological interdependent systems have been shown to be highly vulnerable due to cascading failures and an abrupt collapse of global connectivity under initial failure. Mitigating the risk by partial disconnection endangers their functionality. Here we propose a systematic strategy of selecting a minimum number of autonomous nodes that guarantee a smooth transition in robustness....

Erosional and sedimentary features associated with flooding have been documented in both modern and past cases. However, only a few studies have demonstrated the relationship between these features and the corresponding hydraulic conditions that produced them, making it difficult to evaluate the magnitude of paleo-flooding. This study describes the characteristics associated with inundation dep...

Deep-water sandstones of the Delaware Mountain Group in west Texas and southeast New Mexico contained an estimated 1.8 billion bbl of original oil in place, but primary recovery from these fields is commonly less than 20%. East Ford field in Reeves County, Texas, which produces from the Ramsey sandstone in the upper Bell Canyon Formation, went directly from primary production to tertiary recove...

This paper presents early results of applying the TerraSAR-X multi-polarized data to the task of identifying problems on earthen levees. This application could save levee managers much time and expense in monitoring levees by prioritizing them according to urgency for closer inspection and analysis. One particular sign of potential impending levee failure is the appearance of a slough slide. Ea...

abstract     the major constraints of agricultural production in the south western coastal areas of bangladesh are soil and water salinity of varying degrees, lack of fresh water for irrigation, slow soil drying pattern which are being augmented further due to climate change, requires suitable options of farming systems and component technologies. the major constraints and potentials of agricul...

The stabilized channel is a crucial element of an ‘a‘ā flow system, delivering lava to forward extending zones dispersed flow. However, the term stable implies that geometries, properties, and dynamics are invariable. just how these in space time? To answer this question, we constrain degree variation for extremely well-exposed on Kīlauea (Hawai’i), carrying out mapping, facies analyses, sampli...

An inundation simulation has been done for the mid-eastern Dhaka (37.16 km 2 ) on the basis of Digital Elevation Model (DEM) data from Shuttle Radar Topography Mission (SRTM) and the observed flood data for 32 years (1972-2004). The topography of the project area has been considerably changed due to rapid land-filling by land developers. So, collected DEM data has been modified according to the...

Large-scale disasters, such as hurricanes, cyclones, tsunamis, and forest fires, have caused considerable damage in recent years. This study investigated two case studies of discontinuous open levees (kasumi-tei), which are a traditional Japanese river technology, on the Matsuura River at sites Okawano Azame-no-se, evaluated advantages these from perspective ecosystem-based disaster risk reduct...
