Characteristics and Importance of Rill and Gully Erosion: a Case Study in a Small Catchment of a Marginal Olive Grove
Cuadernos de Investigación Geográfica 2015 Nº 41 (1) pp. 107-126 ISSN 0211-6820 DOI: 10.18172/cig.2644 © Universidad de La Rioja CHARACTERISTICS AND IMPORTANCE OF RILL AND GULLY EROSION: A CASE STUDY IN A SMALL CATCHMENT OF A MARGINAL OLIVE GROVE E.V.

ABSTRACT. Measurements of gullies and rills were carried out in an olive or- chard microcatchment of 6.1 ha over a 4-year period (2010-2013). No tillage management allowing the development of a spontaneous grass cover was imple- mented in the study period. Rainfall, runoff and sediment load were measured at the catchment outlet. The objectives of this study were: 1) to quantify erosion by concentrated flow in the catchment by analysis of the geometric and geomor- phologic changes of the gullies and rills between July 2010 and July 2013; 2) to evaluate the relative percentage of erosion derived from concentrated runoff to total sediment yield; 3) to explain the dynamics of gully and rill formation based on the hydrological patterns observed during the study period; and 4) to improve the management strategies in the olive grove. Control sections in gullies were established in order to get periodic measurements of width, depth and shape in each campaign. This allowed volume changes in the concentrated flow network to be evaluated over 3 periods (period 1 = 2010-2011; period 2 = 2011-2012; and period 3 = 2012-2013). -

A similar process, weathering, breaks down or dissolves rock, but does not involve movement. Erosion is the opposite of deposition, the geological process in which earthen materials are deposited, or built up, on a landform. Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier). If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. The brown color indicates that bits of rock and soil are suspended in the fluid (air or water) and being transported from one place to another. This transported material is called sediment. Physical Erosion Physical erosion describes the process of rocks changing their physical properties without changing their basic chemical composition. Physical erosion often causes rocks to get smaller or smoother. Rocks eroded through physical erosion often form clastic sediments. -

Rabindranath Tagore's Model of Rural Reconstruction: a Review
[ VOLUME 5 I ISSUE 4 I OCT.– DEC. 2018] E ISSN 2348 –1269, PRINT ISSN 2349-5138 Rabindranath Tagore’s Model of Rural Reconstruction: A review Dr. Madhumita Chattopadhyay Assistant Professor in English, B.Ed. Department, Gobardanga Hindu College (affiliated to West Bengal State University), P.O. Khantura, Dist- 24 Parganas North, West Bengal, PIN – 743273. Received: July 07, 2018 Accepted: August 17, 2018 ABSTRACT Rabindranath Tagore’s unique venture on rural reconstruction at Silaidaha-Patisar and at Sriniketan was a pioneering work carried out by him with the motto of the wholesome development of the community life of village people through education, training, healthcare, sanitation, modern and scientific agricultural production, revival of traditional arts and crafts and organizing fairs and festivities in daily life. He believed that through self-help, self-initiation and self-reliance, village people will be able to help each other in their cooperative living and become able to prepare the ground work for building the nation as an independent country in the true sense. His model of rural reconstruction is the torch-bearer of so many projects in independent India. His principles associated with this programme are still relevant in the present day world, but is not out of criticism. The need is to make critical analysis and throw new lights on this esteemed model so that new programmes can be undertaken based on this to achieve ‘life in its completeness’ among rural population in India. Keywords: Rural reconstruction, cooperative effort, community development. Introduction Rathindranath Tagore once said, his father was “a poet who was an indefatigable man of action” and “his greatest poem is the life he has lived”. -

The transport mechanism caused by the consequent rainfall-runoff process determines the amount of generated sediment that can be transferred downslope. Many significant studies and models are performed to investigate these processes, which differ in terms of their effecting factors, approaches, inputs and outputs, model structure and the manner that these processes represent. This paper attempts to review the related literature concerning sediment transport modelling in shallow waters. A classification based on the representational processes of the soil erosion and sediment transport models (empirical, conceptual, physical and hybrid) is adopted, and the commonly-used models and their characteristics are listed. This review is expected to be of interest to researchers and soil and water conservation managers who are working on erosion and sediment transport phenomena in shallow waters. -

UGC NET in Geography, Rajiv Gandhi National Junior Research Fellow and Asst. Teacher Ahiran Hemangini Vidyayatan High school., M.A, NET Abstract: In this paper we discuss the human resource development of Birbhum District. The data have been collected from District Statistical Handbook, District census report of 2001 and District Human Development Report 2009.A large part of the Birbhum District is still backward with respect to human resource development. Aim of this paper is to study the cause of the backwardness of this district. “HRD is the process of determining the optimum methods of developing and improving the human resources of an organization and the systematic improvement of the performance of employees through training, education and development and leadership for the mutual attainment of organizational and personal goals” (Smith). HRD is an important topic of present time. It is considered by management professionals, as sub discipline of Human Resource Management( HRM), but many researchers have, broadened the scope and integrated the concept of HRD by looking it from socioeconomic angle and giving it other dimension such as physical, intellectual, psychological, social, political, moral and spiritual development. I. Introduction: Human Resource Development is the ultimate goal of National Development. HRD is the process of increasing the knowledge, the skills, and the capacities of all the people in a society. -

Rill Erosion on an Oxisol Influenced by a Thin Compacted Layer 1383
RILL EROSION ON AN OXISOL INFLUENCED BY A THIN COMPACTED LAYER 1383 Nota RILL EROSION ON AN OXISOL INFLUENCED BY A THIN COMPACTED LAYER(1) Edivaldo Lopes Thomaz(2) SUMMARY The presence of compacted layers in soils can induce subprocesses (e.g., discontinuity of water flow) and induces soil erosion and rill development. This study assesses how rill erosion in Oxisols is affected by a plow pan. The study shows that changes in hydraulic properties occur when the topsoil is eroded because the compacted layer lies close below the surface. The hydraulic properties that induce sediment transport and rill formation (i.e., hydraulic thresholds at which these processes occur) are not the same. Because of the resistance of the compacted layer, the hydraulic conditions leading to rill incision on the soil surface differed from the conditions inducing rill deepening. The Reynolds number was the best hydraulic predictor for both processes. The formed rills were shallow and could easily be removed by tillage between crops. However, during rill development, large amounts of soil and contaminants could also be transferred. Index terms: conventional tillage, plow-pan, hydropedology, surface runof, rill erosion. RESUMO: EROSÃO EM RAVINA EM UM LATOSSOLO INFLUENCIADO POR UMA CAMADA COMPACTADA RASA A presença de uma camada compactada no solo pode induzir a subprocessos como a descontinuidade hidráulica e impor outros limiares para a erosão dele e o desenvolvimento de ravina. Neste estudo foi avaliado como a erosão em ravina em um Latossolo é influenciada por um pé-de-grade. No estudo ficou demonstrado que ocorre mudança nas variáveis hidráulicas quando o topo do solo é erodido e a camada compactada fica próxima da superfície. -
