Research ArticleOpen accessEvery word in the titleAnalytical Estimation of Geotherm for Multi Layer Model from Heat Flow Equation: A Case Study of Parts of Chad Sedimentary Basin, NigeriaEmujakporue Godwin OmokenuThe subsurface temperature distribution of part of Chad sedimentary basin has been determined by applying analytical solution for multi-layer-model in solving the 1-D steady state conductive heat flow equation. Four-layer model was adopted because the Chad basin is made up of four lithostratigraphies. In this model, equilibrium geotherm of the four layers was computed by considering each layer separately while … …Physics International, Vol. 7, Issue 2 · 6 Oct 2017 · 8,314 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Study of the Higher Aquatic Flora of the Middle Don Basin within Rostov RegionMichael M. Sereda, Olga A. Kapralova, Vlada A. Sereda et al.Middle Don basin is recognized as a biodiversity hotspot, characterized by high diversity of vascular terrestrial plants. However, the significance of its freshwater biodiversity is not well understood now. In the given paper we present the results of the investigation of higher aquatic flora of basin streams and reservoirs within the Middle Don, Rostov region. 90 species of 53 genera … …OnLine Journal of Biological Sciences, Vol. 15, Issue 4 · 29 Oct 2015 · 6,956 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 titleFuture Water Budgets and Water Supply Stress under Climate Change and Urbanization in the Upper Neuse River Basin, North Carolina, USAMichelle Tong Sun, Ge Sun, Chong Liu et al.Urbanization and climate change are the two major threats to watersheds and the environment in the United States. It is imperative to understand the sensitivity of hydrologic responses to climate and urbanization across different physiographic regions in order to formulate sound watershed management strategies and policies. This study evaluated a watershed water balance model, Water Supply Stress Index (WaSSI), with … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 30 Jun 2015 · 7,162 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePORE-PRESSURE PREDICTION FROM SEIMIC DATA IN PARTS OF THE ONSHORE NIGER DELTA SEDIMENTARY BASINEmujakporue Omokenu GodwinPore pressure prediction in parts of the Onshore Niger Delta Sedimentary Basin using seismic reflection data has been carried out. The Bower’s technique of velocity-to-pore pressure transform was adopted. The seismic velocities were derived from the seismic data using layer cake velocity model and were later compared with the available sonic logs velocities obtained from the area. Parameters in the … …Physics International, Vol. 4, Issue 2 · 20 Mar 2014 · 7,437 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLithofacies and Depositional Environment of Volcano-Sedimentary Deposits of Se Mayo Oulo BasinElie Fosso Menkem, David Sebag, Benjamin Ngounou Ngatcha, Alain DurandThe study of volcano-sedimentary deposits of Mangbai in SE Mayo Oulo basin-Cameroon leads to the identification of five major distinct lithofacies types. From the coarset to the finest lithofacies, there are: Gb-clast supported by massive coble and boulder, Gg-granule to massive gravel, Sm-massive sand, Sh-horizontal layered sandstones, Fml-massive laminated claystones. Coarse facies (Gb, Gg, Sm) are cemented with volcanic matrix … …Current Research in Geoscience, Vol. 3, Issue 2 · 19 Dec 2013 · 7,372 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleElectron Spin Resonance Study of Tertiary Sediments in Mae Moh Basin, Lampang ProvinceTidarut Vichaidid, Supanee Limsuwan, Pichet LimsuwanElectron Spin Resonance (ESR) studies have been carried out on Tertiary sediment collected from Mae Moh basin, well known for its lignite mining in Lampang province of the northern Thailand, a stratigraphic bedding plane in the sediment that formed in geological time of about 13 million years ago. Each individual sedimentary bed has its own unique assemblage and occurs in … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 14 Jul 2012 · 7,172 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVegetation Analysis of Sutan-Chay Basin in ArasbaranT. Ebrahimi Gajoti, V. Haciyev, A. Javanshir et al.Problem statement: Plants associations differ in relation to environmental gradients. Therefore, it is necessary to study the interaction between ecological factors and vegetation. Approach: In this study vegetation and flora of Sutan-Chay Basin in Arasbaran was investigated using Braun Blanquet method as physiognomic floristic. Sampling of soil and vegetation was carried out by selecting areas with homogenous plant compositions. The … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 7,879 accessesView PDFCite
