Wetlands in West Africa are among the most vulnerable ecosystems to climate change. West African wetlands are often freshwater transfer mechanisms from wetter climate regions to dryer areas, providing an array of ecosystem services and functions. Often wetland-specific data in Africa is only available on a per country basis or as point data. Since wetlands are challenging to map, their accuraci...

Mapping irrigated areas of a river basin is important in terms of assessing water use and food security. This paper describes an innovative remote sensing based vegetation phenological approach to map irrigated areas and then the differentiates the ground water irrigated areas from the surface water irrigated areas in the Krishna river basin (26,575,200 hectares) in India using MODIS 250 meter ...

this experiment was conducted for estimating the effect of row spacing and plant density on soil moisture change, wheat yield and water use efficiency in rainfed condition, using a three replicated randomized complete block design with factorial arrangement at gorgan university of agricultural sciences and natural resources farm in anbare-ololum region in 2008-2009. the treatments that used wer...

Space interferometers consisting of several free flying telescopes, such as the planned Darwin mission, require a complex metrology system to make all the components operate as a single instrument. Our research focuses on one of its sub-systems that measures the absolute distance between two satellites with high accuracy. For Darwin the required accuracy would be in the order of 10 μm over 250 ...

in this research, industrial wastewater treatment plants (iwwtps) were investigated and categorized by effluent applications and electrical energy cost. for the purpose of this research, 51 plants were assessed and results indicate that 17 plants discharged the effluent directly to the surface water that most of them are located in north of iran, 24 plants used the effluent for irrigation. othe...

Sedimen yang terbawa air menjadi salah satu permasalahan memiliki dampak buruk terhadap ekosistem keairan, terlebih bila tersebut digunakan sebagai konsumsi masyarakat. Salah mitigasi dapat dilakukan adalah dengan adanya konstruksi bangunan penangkap sedimen agar tidak mengandung banyak padatan berisi nutrien limbah pencemar. Dalam penelitian ini, estimasi dimensi penangkan di Kota Cirebon meng...

This document provides a description of the small and medium range gas flow calibration facilities at the National Institute of Standards and Technology (NIST) Fluid Flow Group, as reported in NIST Special Publication 250 [1] for Test Nos. 18010C-18040C and 18050S, Flow Rate Measurements. The Fluid Flow Group can perform gas meter calibrations and special tests at flows between 3.7 x 10"^ mVmin...

Selat Makassar merupakan lintasan pertama arlindo yang dimana ini sebagaian besar mentransfer air kemudian menuju selat Lombok. Arus lintas Indonesia membuat perairan terutama bagian timur menjadi subur akibat adanya proses upwelling dan pencampuran serta interaksi dengan udara menyebabkan kandungan nutrisi mineral kaya pada lapisan laut dalam. Beberapa penelitian tentang plankton di masih berk...
