In the present study, the eighteen miniwatersheds of Kadam watershed of Middle Godavari sub basin (G-5) have been prioritized using GIS based on morphometric analysis. The highest Bifurcation ratio is found to be 11.95 for 4E3C5a. The Maximum values of Circularity ratio of 0.642 and Drainage density of 3.510 have been found in Lothuvara miniwatershed. The Maximum values of Stream frequency of 7...
The deterministic field scale model DRAINMOD was tested in an experiment on subsurface pipe drainage in the Veneto region, in an environment of NE Italy characterised by the presence of a shallow water table in a flat area. The objective was to determine whether a minimal set of field data would suffice to use DRAINMOD for predictive purposes. The measured water table depth and drain outflow fr...
Sub-watershed prioritization is very important in natural resources and watershed management. This study deals with prioritization of sub-watersheds using a mixed multivariate linear model of New TOPSIS-Regression over morphometric parameters of 11 sub-watersheds. Morphometric parameters include constant of compression ratio, roundness factor, form ratio, slenderness ratio,channel maintenance, ...
Soil moisture is a key state variable of the hydrologic cycle. It plays a significant role in many hydrological, meteorological and other natural processes in the land-atmosphere continuum. In the past two decades we have conducted several field campaigns to better understand the underlying processes controlling the spatio-temporal variations of soil moisture using multiple ground, air, and spa...
The growth of world population and the demand for agricultural products can be regarded as one of the important issues that humanity has ever faced. There are serious concerns regarding surface and ground water pollution by nitrates because of using nitrogen fertilizers in the agriculture. Improving agricultural water management systems can reduce nitrate in drainage outflow and therefore, redu...
electrical steels are important alloys widely used in electrical instruments. the magnetic properties and low core loss of grain oriented silicon steels are closely related to the sharpness of goss texture ({110} ).the direction of is the softest direction for magnetism. in this work, the microstructure and dependence of orientation density along the major texture fibers on the applied cold ro...
This study aims to determine the activity of farmers and physical properties soil on rice fields in village Detusoko Barat, District, Ende Regency. The research method used is purposive sampling. was carried out paddy Barat chemical laboratory Faculty Agriculture, Undana. Farmer variables observed were cultivation such as seedbed, land preparation, planting, fertilizing, maintaining, harvesting...
Soil physical properties, such as soil texture, color, bulk density, and porosity are important determinants of water flow (e.g., infiltration drainage), biogeochemical cycling, plant community composition. In addition, they reflect the environment in which developed, giving insight into climate, mineralogy, land cover. While many assessments require sophisticated laboratory equipment, some can...
Soil microbial properties are known to exhibit high spatial and temporal variability, which can hinder our understanding of the effects of agricultural management on soil microbial activities, populations and communities. However, if this variability is explicitly considered in soil sampling schemes, experimental results can help us better understand soil microbial properties. In this initial a...
