sub basin prioritization is one of the integrated watershed management and sustainable development strategies. to protect natural resources, through marking zones of potential damage in small areas for is a primary need sustainable development. degradation potential zones project for watershed protection measures is not cost-effective economically. so this is a prerequisite for sub basin priori...

planning of watersheds is indispensable in terms of sustainable development and landscape management. therefore, watershed prioritization and morphometric characterization are important to identify hydrological behavior of the basin for conducting management strategies. in this study, geospatial-statistical approach was used for identifying critical and priority sub-watersheds in the golestan w...

Abstract Bubble coalescence in ascending magma is a key process that controls the eruption violence and texture of volcanic pyroclasts. In present study, we performed situ experiments to investigate two growing bubbles highly viscous liquids (102 1,020 Pa ⋅ s). A new experimental apparatus enables us directly observe drainage film between three dimensions. We combined results simple scaling ana...

abstract water retention curve (wrc) is a fundamental property of soil. it is used to evaluate available water, permeability, drainage and movement of solutes. despite numerous studies on wrc of soils abroad, no local study has been carried out on charmahal-va-bakhtiari soils. the objective of this study was to compare the quality of fitting of several wrc models to lordegan soils and to select...

Abstract The critical step in increasing water availability and land productivity areas with freshwater scarcity, such as arid semi-arid, is identifying suitable sites for Rain Water Harvesting (RWH). Identifying RWH site-specific due to a wide variety of region’s characteristics. Biophysical (slope, soil texture, drainage density, use), hydrological (runoff potential), socio-economic (distance...

the objective of this study was to determine the allowed and desired limits for heavy soils of texture (clay loom), as it has operational capability (friability), these limits were 6.34 mm for planting and 10.62 mm for harvesting in each raining or irrigation episode. we determined some factors that affect soil wetness and water content as follow: the amount and severity of rain, the condition ...

Evaluation of the level land suitability for rice crops is used in planning agricultural use so that inhibiting factors and solutions can be found processing to planted. This study aims evaluate crop plants by implementing a geographic information system facilitates accelerates data process research output consideration Tanjung Selor Subdistrict Bulungan District. The variable this was temperat...

Abstract The Upstream Cibeet sub-watershed is part of the Citarum watershed and with an area 69.35 km 2 . Hydrologically, upstream usually functions as a recharge area, its development should be geared towards land conservation erosion mitigation. Parameters rainfall, soil type texture, geology, lineament density, drainage geomorphology, cover are used in predicting most potential catchment are...

DOI:10.17014/ijog.9.2.147-157 Outcrop of Nanggulan Formation, surrounded by Old Andesite Formation (OAF) in the eastern part Kulon Progo Dome, is very limited. Tectonic control interpreted as a contributing factor. activity can be shown morphometric aspect. The research purpose was to calculate valley floor - height ratio, stream gradient index, and drainage density Formations. method used fiel...
