Anand Agricultural University, Anand

Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

    EVALUATION OF A SENSOR BASED MECHANISM FOR SOIL INFILTRATION TESTS
    (COLLEGE OF AGRICULTURAL ENGINEERING AND TECHNOLOGY ANAND AGRICULTURAL UNIVERSITY GODHRA, 2019) BHANDERI HARSH MAGANBHAI; Dr. M. L. GAUR
    Infiltration remains one of the leading physical process during entire hydrologic cycle at varied scales all along time and space. It is an important subject of research for integrated planning & management of rainwater as well as irrigation water, to affect surface runoff, soil erosion, and groundwater recharge. All kind of hydrologic models and rainfall-runoff relations on lands are entirely governed & regulated by accuracy in its estimates. Even in a present era of advanced models/modelling, such estimates remain highly uncertain/unrealistic as they are merely based upon the point values of soil infiltration that are mostly generated by using one or other kind of infiltrometers (single ring or double ring based) with an artificial nature & magnitudes of water ponding. Owing to inherent conceptual weaknesses of ring-based tests and also other dissimilar conditions in contrast to real rainfall/irrigation-based infiltration, estimation of infiltration remains a biggest weakness. Majority of such traditional ring results remained confined and focussed to offer merely a representative estimate of some kind of steady state rates of water entry into soil for a particular test location/condition, which is ultimately taken as a closer estimation of saturated hydraulic conductance of soil. Being a prominent hydrologic loss function, the temporal & spatial distribution of infiltration always remains a key input while rainfall is partitioned into rainfall excess. Majority of researchers still states that ‘poor infiltration estimation’ is the weakest link even in present era of advanced models & modelling for hydrological or any kind of water resources developments.
