BACKGROUND Peatlands play an important role in the global carbon cycle. They provide important ecosystem services including carbon sequestration and storage. Drainage disturbs peatland ecosystem services. Mapping drains is difficult and expensive and their spatial extent is, in many cases, unknown. An object based image analysis (OBIA) was performed on a very high resolution satellite image (Ge...
surface and subsurface water collection in small seasonal rivers is very crucial, particularly in dry seasons. in this study a type of intake is introduced which acts as a river drainage network. an experimental model of the subsurface intake was constructed and the effective parameters such as upstream discharge, installation depth, and drain intervals were evaluated. the results showed that t...
A 19-year-old male patient presented cyanosis and dyspnoea because of the presence of multiple pulmonary arteriovenous fistulas resulting in oxygen desaturation. The CTA revealed that intestinal and splenic venous blood bypasses the liver and drains into the inferior vena cava. This is the first reported case of hepatopulmonary syndrome caused by congenital extrahepatic portosystemic shunt in w...
The Amber El Amino area is located 75 kilometres southeast of Prince Rupert. Access to the area is by helicopter from Prince Rupert or Terrace (Figure 1). The El Amino showing (BC MINFILE 103H 071) is located on Sulphide Creek (Figure 2) which drains eastward into Hanna (El Amino) Creek. The Amber showing (BC MINFILE 103H 171) is located 700 metres north of the El Amino showing. Hanna Creek dra...
Background: Land degradation is one of the major challenges in developing nations like Ethiopia. The study was conducted on both conserved and non-conserved land. A total 18 composite soil samples were collected from top 0-20 cm depths to analyze selected physical chemical properties soil. Methods: For data analysis one-way variance (ANOVA) used. From our observation water conservation practice...
