Research ArticleOpen accessEvery word in the titleWave Characteristics in Sabah WatersEjria Saleh, Jessie Beliku, Than Aung, Awnesh SinghProblem statement: This study was conducted to identify and compare the wave characteristics in Sabah waters at five different key locations so as to determine the effects of the Northeast Monsoon (NEM) and the Southwest Monsoon (SWM) along the east and west coasts of Sabah. Approach: Monthly wave height and wave period data for 8 years covering offshore areas of … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,745 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetection of Rotten Fresh-Cut Cauliflowers based on Machine Vision Technology and Watershed Segmentation MethodJianxin Xue, Liang Huang, Bingyu Mu et al.In this study, machine vision technology was used to separate the samples and detect the rotting degrees of fresh-cut cauliflowers. First, the improved watershed algorithm was used for the segmentation of fresh-cut cauliflower samples and the extraction of single-sample. Then, three color models, a gray co-occurrence matrix and two feature extraction algorithms were used to extract the color, texture and … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 2 · 13 Apr 2022 · 6,083 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Watershed Structures in Controlling Runoff - Case Study of Sardasht Basin in IRANSeyedeh Zahra Hosseini-Teshnizi, Ghodratollah Davoudi, Seyedeh Laleh Razavi, Kaveh Ostad-Ali-AskariIn order to investigate the performance of constructed structures in Sardasht watershed, Soil and Water Assessment Tools model for simulation of runoff and sediment during the studied period of 1996-2012 was carried out for two cases of existence and absence of flood control structures. From 2007 onwards by performing watershed operations in these sub-basins, the average runoff rate decreased about … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 26 Feb 2020 · 7,346 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIdentification of Erosion Hotspot Area using GIS and MCE Technique for Koga Watershed in the Upper Blue Nile Basin, EthiopiaTewodros T. Assefa, Manoj K. Jha, Seifu A Tilahun et al.Soil erosion is a serious threat in Ethiopian highlands. Continuous land degradation resulted in loss of fertile top soil leading to low agricultural productivity. In addition, excessive soil erosion from Koga Watershed in upper catchment to an artificial reservoir (Koga Dam reservoir) is substantially reducing its service life. Community participatory based effective watershed management strategies may have tremendous potential to … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 10 Sep 2015 · 9,147 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA NOVEL APPROACH TO DETECT FISSURES IN LUNG CT IMAGES USING MARKER-BASED WATERSHED TRANSFORMATIONK. Devaki, V. Murali BhaskaranDetection and segmentation of fissures is useful in the clinical interpretation of CT lung images to diagnose the presence of pathologies in the human lungs. A new automated method based on marker-based watershed transformation has been proposed to segment the fissures considering its unique structure as a long connected component. Marker based watershed transformation is applied and morphological operations are … …Journal of Computer Science, Vol. 10, Issue 6 · 25 Jan 2014 · 6,425 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePotential Zones of Peruvanthanam and Valiyathodu Sub-Watersheds of Manimala River BasinVadakkepurakkal Rekha, Aikara Varkey George, Rita MendezGroundwater is a dynamic and replenishable natural resource. But in hard rock terrains, its availability is of limited extent. In sub-watershed studies, remote sensing and GIS techniques have the advantages of spatial, spectral and temporal data, covering large and inaccessible areas within a short span of time. Thus this technique has become a very handy tool in assessing and monitoring … …American Journal of Environmental Sciences, Vol. 9, Issue 1 · 20 Feb 2013 · 7,389 accessesView PDFCite
