Research ArticleOpen accessIn the abstractIdentification 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 accessIn the abstractMonitoring Land Use and Land Cover Effects on Water Quality in Cheung Ek Lake using ASTER ImagesNara Im, Kensuke Kawamura, Endan Suwandana, Yuji SakunoCheung Ek Lake is the biggest natural treatment plant for nearly 80% of wastewater and storm-water from Phnom Penh city. Land Use and Land Cover (LULC) changes of the lake and its catchment area could deteriorate capacity of the lake in purifying wastewater and affect to its water quality. The study aims to assess the relationship between LULC changes and … …American Journal of Environmental Sciences, Vol. 11, Issue 1 · 3 Apr 2015 · 8,013 accessesView PDFCite

Research ArticleOpen accessIn the abstractAn Approach to the Model use for Measuring Suspended Sediment Yield in Ungauged CatchmentsSokchhay Heng, Tadashi SuetsugiDifferent types of water resources studies require the information of Suspended Sediment Yield (SSY) in different time resolutions. In ungauged watersheds where hydrometeorogical time series are not available, the mean annual SSY (SSYa) is solely predictable and catchment area is traditionally used as the predictor because it is the most important variable and generally determined during project planning. Firstly, this … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 11 Sep 2013 · 6,991 accessesView PDFCite
Research ArticleOpen accessIn the abstractLand Degradation and Preventive Measures From the Perspective of the StakeholdersMosayeb Heshmati, Arifin Abdu, Nik Muhamad Majid, J. ShamshuddinLand degradation at the catchment scale in Iran is widespread, usually assumed to be accelerated by the activities of local inhabitants. Social issues such as low income, poverty and low level of welfare and education contribute to land degradation. A study was conducted to identify the causes of land degradation in Merek catchment, Iran and to propose appropriate measures to … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 8,367 accessesView PDFCite

Research ArticleOpen accessIn the abstractValidation of MIKE 11 Model Simulated Data for Biochemical and Chemical Oxygen Demands TransportMahdieh Eisakhani, Md. Pauzi Abdullah, Othman Abd Karim, Amirhossein MalakahmadProblem statement: The aim of the study was to model the discharge, biochemical and chemical oxygen demands (BOD and COD) loads in each cross section of Bertam River in Cameron Highlands, Malaysia. Cameron Highlands form the headwater catchment for two major rivers of the lowlands; Pahang River and Perak River. On the other hand, Cameron Highlands is undergoing rapid development … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 27 Jan 2012 · 7,686 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Deforestation on the Runoff-Peak by KINFIL ModelAlireza Mardookhpour, Leila OoshaksaraieProblem statement: In present study the KINFIL model was used for the catchment management, including the investigation of deforestation on predict flood runoff assessment with a significant precision. Approach: The KINFIL rainfall-runoff model has been used for the reconstruction of the rainfall runoff events in agricultural land use. The implementation of the KINFIL model supported by GIS proved to be … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 24 Dec 2011 · 6,859 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Land Use Practices on the Organic Carbon Content, Cation Exchange Capacity and Aggregate Stability of Soils in the Catchment ZonesMosayeb Heshmati, Arifin Abdu, Shamshuddin Jusop, Nik Muhammad MajidProblem statement: Land use practice leads to changes in the physico-chemical properties of soils, such as Soil Organic Carbon (SOC), Cation Exchange Capacity (CEC) and Soil Aggregate Stability (SAS) that cause soil erosion. Approach: Merek catchment, Iran suffers from land degradation due to poor land use practice. A study was carried out with the objectives: (i) to determine soil nutrient … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 25 Oct 2011 · 8,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractVertical Profile of C, N, P, K and Radionuclides in Soil Collected from Highland Tea Plantation AreasZaini Hamzah, Seh Datul Riduan, Ahmad SaatProblem statement: Cameron Highlands is a well known agricultural area in Peninsular Malaysia.
