ABSTRACTTerrestrial ecosystems store more carbon (C) than the atmosphere and provide ecosystem services (ES) such as global climate regulation, by sequestering within biomass soil. Land ...
Nonlinear multiple‐regression analysis is used to derive relations among the velocity, sediment discharge, bed‐form geometry, and friction factor of alluvial rivers. A data base comprising 339 river flows 608 flume in analysis. hierarchy formulations involving progressively more interdependencies depth, geometry developed. Procedures for computing velocity‐ sediment‐rating curves are presented. simplified procedure preparing depth‐discharge streams with strongly, discontinuous rating also...
An updated assessment of land sensitivity to desertification is essential for comprehensive planning and preparation action plans. In this study, modified Mediterranean use (MEDALUS) method by employing a fuzzy inference system in GIS environment was used identify environmentally sensitive areas (ESA) the Drader basin Morocco. Anthropogenic Biophysical parameters (17 parameters) have been integrated processed geographic information systems obtaining climate, water, soil, vegetation...
Formulations for bed armoring and hydraulic sorting of sediments in alluvial streams are developed, an application to Missouri River evolution is presented. A relation the areal coverage factor on a plane first formulated as function degradation depth bedmaterial characteristics, then modified by introducing correction factors effect forms stochastic nature sediment motion. For simulation sorting, assumed be mixed homogeneously mixed‐layer approximately equal average bedform height,...
An equation for the exponent in power‐law velocity distribution is formulated by relating rate of energy dissipation due to turbulent shear sediment bed‐layer increased fluid‐shear produced moving sediment. The suspended‐sediment concentration corresponding profile calculated and simplified. relation derived found be good agreement with data from a large group flume river flows. powerlaw are shown excellent conformity distributions measured Vanoni Brooks.
Laboratory experiments were performed in a 40‐ft long, 2‐ft wide, 1‐ft deep (12‐m×0.6‐m×0.3‐m) tilting flume to elucidate the effects of temperature variations on flow and sediment‐transport characteristics streams with beds fine sand (D50=0.11mm these experiments). Nearly constant depth was maintained three different discharges, temperatures varied from approximately 30° C near 0° C. In two series at higher velocities Froude numbers, reductions produced major increases sediment discharge...
The future course of bed degradation in the middle Missouri River has been predicted using numerical simulation techniques. required development new Total Load Transport Model (TLTM), which incorporates interdependence friction factor and sediment transport through data‐based empirical relations. TLTM was implemented a mathematical model called IALLUVIAL, computes quasi‐steady water flow natural rivers having nonuniform sediments. IALLUVIAL also bed‐sediment sorting armoring, are processes...
Globally, green space landscape structure has been used as tourist attraction in cities to increase the economy of country tourism sector. However, lack characterization led poor management such information on tourists and younger generations, thereby decreasing revenue. The purpose this study is characterize three sites structures with potential for Kota Bharu, Kelantan, Malaysia future sustainable ecotourism site planning. are Taman Perbandaran Tengku Anis, K4 Riding Horse Splash Water...
Globally, the amount of green space in urban areas has significantly decreased because fast expansion. Urbanization may modify spatial structure a landscape and have an impact on its ecological function. The research aims to quantify changes years 1994, 2004, 2014 Pasir Mas using remote sensing, GIS ecology approach. Three satellite images were classified into five land use cover (LULC) which are forest, agriculture area, cleared land, water bodies built-up area. results show that highest...
Abstract Weeds in oil palm plantations include any plant or vegetation that way interferes with the production of palms, resulting a reduction yield quality. Alocasia sp. (wild yam) is common weed at plantation Borneo, Malaysia. This study was conducted to evaluate commercial herbicides’ effectiveness (amine, ally, glyphosate, and paraquat) against sarawakensis , robusta A. macrorrhizos . Cocktail herbicide showed faster wilting, scorching rotten least/late regeneration within 30 days...
