Hydraulic conductivity values

This paper presents the results and assessment of the groundwater exploitation reserves in coastal areas of Ninh Thuan province. The research was based on determining the exploitation reserves of all grid cells with dimensions 500 m × 500 m distributed in fresh-salted water areas of the Holocene (qh) and Pleistocene (qp) aquifers. Each grid was assigned the corrected hydrogeological parameter values (depth, gravity coefficient, hydraulic conductivity, and drawdown level).

An Investigation on physico-chemical properties, NPK and micro nutrient status of soils of Janpad major, Left bank canal, Nagarjuna Sagar Project (NSP), Telangana, India was carried. The soils are having clay content ranging from 6 to 24 per cent, silt content from 4 to 20 per cent and sand content from 69 to 87 per cent. The Hydraulic conductivity varied from 15 to 20 cm day-1 with a mean value of 17.5 cm day-1 . Mostly the soils under the command area are slightly acidic to slightly alkaline and non-saline in nature.

One of the easiest and efficient way of water conservation to solve drinking water scarcity is rooftop water harvesting. To evaluate the performance of the first flush with micromesh filter system, inflow and outflow of the rooftop water samples were analysed for pH, EC, TDS, SAL and TSS parameters. In general, the PH, electrical conductivity, and TDS of the roof water samples were within the drinking water standards and the first flush with micromesh filter system was found to reduce TDS values.

Field experiments were conducted in sandy clay loam soils to assess the effect of different levels of fertigation and emitter types on hydraulics of drip irrigation, movement of soil moisture distribution and yield of tomato. The three levels of fertigation i.e. fertigation with 100% recommended dose of fertiliser (RDF), 80% RDF and 60% RDF and four types of emitters viz.

Present study was undertaken at Hirakud command area of Odisha to investigate the effect of continuous irrigation on soil texture, bulk density and saturated hydraulic conductivity of different soils. Soil samples were collected from 15 spots each at irrigated areas and unirrigated areas in two different depths at 0-15 cm and 15-30 cm with Global Positioning System (GPS). Both loose and core samples from each spots were collected and analysed for different physical properties.

The study was conducted at Technology Park (Plasticulture Farm) of CTAE, Udaipur, Rajasthan to evaluate performance of automated and conventional drip system for okra crop during year 2019. The Uniformity Coefficient (CU), Distribution Characteristic (DC) and Emission Uniformity (EU) were found to be highest at the head and decreases with increase in distance along the lateral for both irrigation systems. It was found that the average values of all evaluation parameters except DC, were found to be highest for automated drip system.
