Spring flooding of the Red River of the North (RR) is common, but little information exits on how these flood events affect water and overbank sediment quality within an urban area. With the threat of the spring 2009 flood in the RR predicted to be the largest in recorded history and the concerns about the flooding of farmsteads, outbuildings, garages, and basements, the objectives of this stud...

For the flooding seasons of 2011-2012 multiple space assets were used in a “sensorweb” to track major flooding in Thailand. Worldview-2 multispectral data was used in this effort and provided extremely high spatial resolution (2m / pixel) multispectral (8 bands at 0.45-1.05 μ m spectra) data from which mostly automated workflows derived surface water extent and volumetric water information for ...

BACKGROUND Leptospirosis is a zoonosis which is spread through contamined running water. This contaminations is seriously affected by the flooding which occurs in the area surrounding the Aricanduva river. The transmission of the disease results mainly from the contact of water with soil contaminated by the urine of infected animals. We aimed to conduct an epidemiological survey on Leptospirosi...

The deficiency of oxygen in water during submergence is one of the frequently perceived environmental factors that limits or hampers production of the rice cultivation. Rice plants comprise of elongated submerged tissues that help to bear with the rise of water level in natural location. This characteristic helps the plant to deal with flooding stress. The mechanism on flooding tolerance and ad...

Floods trigger cascades of physical processes that alter streams and riparian zones of mountain landscapes, yet affected species are resilient Recent flooding in the Pacific Northwest vividly illustrates the complexity of watershed and ecosystem responses to floods, especially in steep forest landscapes. Flooding involves a sequence of interactions that begins with climatic drivers. These drive...

BACKGROUND AND AIMS Intraspecific variation in flooding tolerance is the basic pre-condition for adaptive flooding tolerance to evolve, and flooding-induced shoot elongation is an important trait that enables plants to survive shallow, prolonged flooding. Here an investigation was conducted to determine to what extent variation in flooding-induced leaf elongation exists among and within populat...

Bridgewater, Nova Scotia, is located 20 km inland from the mouth of the LaHave River estuary on the Atlantic Coast of Canada. Bridgewater is at risk of flooding due to the combined effects of river runoff and a storm surge on top of high tide. Projected increases in sea-level and possible increased river runoff with climate change increase the risk of future flooding. A set of river and ocean w...

  Effect of change from the conventional (flooding) to subsurface irrigation system was studied on mature pistachio trees (Cultivar Ohadi) in Kerman pistachio research station for four years. This experiment was carried out in a randomized complete block design including 7 treatments and 3 replications. The experiment also used two irrigation intervals (7;14 days) and three water rates accordin...

There are two conceptually distinct methods for computing watershed transform in digital images, namely the traditional immersion based simulation and rainfall simulation. The traditional watershed algorithm is usually implemented by simulating a flooding through immersion. The immersion simulation process starts with piercing holes in each minima (LIM), then this surface is gradually immersed ...

BACKGROUND AND AIMS Flooding can occur at any stage of the life cycle of a plant, but often adaptive responses of plants are only studied at a single developmental stage. It may be anticipated that juvenile plants may respond differently from mature plants, as the amount of stored resources may differ and morphological changes can be constrained. Moreover, different water depths may require dif...
