The robust numerical technique for high-resolution reconstructive imaging and scene analysis is developed as required for enhanced remote sensing with large scale sensor array radar/synthetic aperture radar. First, the problem-oriented modification of the previously proposed fused Bayesianregularization (FBR) enhanced radar imaging method is performed to enable it to reconstruct remote sensing ...

In this paper, the modeling is based on division of the catchment into a grid mesh. Each cell has a unique response function independent of the functioning of other cells Summation of the flow responses from the cells, result the flow hydrograph from this area basin.A method is presented to simulation the flow hydrograph within a river basin using the hydrological model WetSpa. WetSpa is a GIS-b...

In recent years, Airborne Laser Scanning (ALS) has become the state-of-the-art technique for topographic data acquisition. Most ALS sensors record the reflected laser beam with X,Y,Z coordinates and the signal amplitude (also referred to as intensity) as a three-dimensional point cloud. One or more echoes,or even the full-waveform can be recorded per laser shot, depending on the scanner type. M...

This paper offers a conceptual approach to explore the complex dynamics of floodplains as fully coupled human-water systems. A number of hydrologists have recently investigated the impact of human activities (such as flood control measures, land-use changes, and settlement patterns) on the frequency and severity of floods. Meanwhile, social scientists have shown how interactions between society...

Water level data obtained from telemetry stations typically contains large number of outliers. Anomaly detection and a imputation are necessary steps in monitoring system. can be detected if its values lie outside normal pattern distribution. We developed median-based statistical outlier approach using sliding window technique. In order to fill anomalies, various interpolation techniques were c...

The atmospheric hydrological cycle is compared for diierent time slices of the late Quaternary. Simulations have been conducted with an atmospheric circulation model at T42 resolution, and we have performed a global evaluation of the atmospheric water vapor transport. The water export from the Atlantic catchment area, important for driving the large-scale thermohaline ocean circulation, is anal...

Concentration plume evolution and chemical persistence at chlorinated solvent contaminated sites are typically controlled by the presence of dense nonaqueous phase liquid (DNAPL) mass within a highly contaminated region or DNAPL source zone. Characterization of both the extent and structure of the source zone DNAPL mass distribution is, thus, of great importance to site assessment and successfu...
