Tropical peatland fires play a significant role in the context of global warming through emissions of substantial amounts of greenhouse gases. However, the state of knowledge on carbon loss from these fires is still poorly developed with few studies reporting the associated mass of peat consumed. Furthermore, spatial and temporal variations in burn depth have not been previously quantified. Thi...

Nutrient loading from the Everglades Agricultural Area and nearby urban communities plus water flow rate and canal size have significantly influenced the amount of sediment and phosphorus (P) pools stored in the Water Conservation Area (WCA) canals in the Everglades. A study was conducted to characterize the potential impact that sediments might have on the overlying water column by conducting ...

A technical survey was conducted in the 16 Poblacion barangays of Catarman, Northern Samar to gather data on existing length drainage canals, land area barangay, and average slope canal. Using a questionnaire, reasons for flooding perceived remedial measures were gathered from barangay residents. The lengths canal range 0.52 – 2.263 km. ranges 0.012 1.572 %. depth maximum 0 (no flooding) 1.3 m....

Soil salinization has become a worldwide issue affecting agricultural development. Statistical methods and spatial analysis were used to analyze the degree type of saline soils their distribution. The driving factors soil salinity explored using Geodetetcor models. In this study, 84 samples collected from 0–20 cm layer, total salt concentration ion composition measured. results statistical clus...

Large hydraulic structures are of major importance to sustained life-support systems and have an impact on the environment. Dams, reservoirs and open canals are such structures, the impact of which has been duly appreciated and addressed in environmental impact assessments and side-effects amelioration programs. Less obvious, but of vital importance, is the impact of urban drainage systems on h...
