Recent studies in theWestern United States have supported climate scenarios that predict a higher occurrence of large and severe wildfires. Knowledge of the severity is important to infer long-term biogeochemical, ecological, and societal impacts, but understanding the sensitivity of any severity mappingmethod to variations in soil type and increasing charcoal (char) cover is essential before w...

Animal treading can change soil physical properties, and thus is an important factor in hydrological modelling. We investigated the impacts of animal treading on infiltration by using a series of rainfall simulation experiments at Whatawhata Research Center, Waikato, New Zealand. The study identified significant variables for estimating soil steady-state infiltration at a microsite (0Ð5 m2) and...

Expansive Black cotton clay soils are widely distributed worldwide, and a significant damage to infrastructure buildigs. It is common practice around the world stabilize black soil using fly ash improve strength of stabilized sub- base sub grade soil. Soil stabilization improvement or bearing capacity by controlled compaction, proportioning addition suitable admixtures stabilizers. The extremel...

the present study was conducted to determine the most appropriate tree species planted in the same ecological condition considering different variables at darabkola forest, mazandran province. for this purpose, the success of planted species (maple, walnut, oak, pine, ash and elm) was assessed according to ninecriteria (soil nitrogen, soil phosphorus, soil potassium, leaf nitrogen, leaf phospho...

CBR (California Bearing Ratio) value is usually used to determine the bearing capacity of a soil type. Soil conditions with low are often found in clay types. There several ways increase clay, one which by adding palm bunch ash. In this research, an analysis changes addition 5%, 7.5%, and 10% oil The results showed that largest was obtained at ash, 7.493%.

From October 26 to November 12, 2010, Indonesia’s Mount Merapi blew its top in the volcano’s largest series of eruptions in decades. It spewed ash and lava rock thousands of meters into the air. Hundreds of thousands of villagers fled, abandoning their homes along with more than 1,000 ha of farm fields to the scalding ash, rock, and mud spilling down the slope (1, 2). The following July, space ...

The Jamshoro soil is a weak and expansive soil. construction of infrastructure on such soils has resulted severe damages huge maintenance costs. Thus, it needs treatment to enhance its geotechnical properties. This research work investigates the effects chemical stabilizers as lime, fly ash, silica fume compaction consolidation characteristics Jamshoro. were added individually in different prop...
