Early flood warning and real-time monitoring systems play a key role in flood risk reduction and disaster response decisions. Global-scale flood forecasting and satellite-based flood detection systems are currently operating, however their reliability for decision making applications needs to be assessed. In this study, we performed comparative evaluations of several operational global flood fo...

Since flood inundation hampers human life and the economy, retrieval with high temporal resolution accuracy is essential for projection of environmental impact. In this study, a novel cyclone global navigation satellite system (CYGNSS)-based index, named annual threshold index (ATFII) retrieval, proposed, grades are quantified. First, CYGNSS surface reflectivity land properties (i.e., vegetatio...

The western Sierra Madre is the main water-providing area of northern Mexico. However, most of this mountain range has suffered a progressive degradation of soils and vegetation due to overgrazing and deforestation, for four or five decades. The objective of this study is to determine the impacts of these changes on water balance and hydrodynamic basin behaviour. The hydrological data of two ba...

In this paper we look at a combination of bulk-compression, partial query processing and skipping for document-ordered inverted indexes. We propose a new inverted index organization, and provide an updated version of the MaxScore method by Turtle and Flood and a skipping-adapted version of the space-limited adaptive pruning method by Lester et al. Both our methods significantly reduce the numbe...

Estimation of Maximum Flood Discharge (MFD) for a given return period is important for planning, design and management of hydraulic structures for the project. This can be achieved through Flood Frequency Analysis (FFA) by fitting of probability distributions to the recorded Annual Maximum Discharge (AMD) data. In this paper, Gamma and Extreme Value family of probability distributions are adopt...

Previously recognized color and pattern variants of adult Cichla temensis in Amazon flood pulse river environments reflect the cycling of individuals through seasonal sexual maturity and spawning. Individuals also vary in shape from blocky to fusiform. To determine if shape differences are related to patterns of fat reserve deposition and utilization, and to quantify the relationship of shape w...
