Floodplains are intermittently flooded complex geomorphic features with positive and negative relief (Lewin & Ashworth, 2014). Negative relief consists of meso-and macro-scale elements that include accessory through-channels, tributary channels, channel margin slackwater zones, bar-shelter backwaters, contiguous channel remnants, tie channels, internal drainage channel networks, and large-scale flood basins occluded by channel-belt aggradation (Lewin & Ashworth, 2014). This negative relief is present on both braided (

A new error detection and correction methodology, defined as Horizontal-Vertical-Diagonal-N-Queen-Parity (HVDNQ), is proposed in this paper. This approach relies on five different types of parities: horizontal parity, vertical parity, forward diagonal parity, backward diagonal parity, and queen parity. This method works on an N X N cell area and can correct multibit upsets. The experimental analysis validates the effectiveness of the proposed methodology by comparing its efficiency with existing methodologies. In different varieties of error patterns such as equilateral triangle, pentagon, hexagon etc., the capability of error detection and correction of HVDNQ is much better than existing methods.
