Abstract

Changing climate of a region coupled with spatiotemporal variability of rainfall has a significant effect on groundwater recharge. An effort has been made in this study to analyse the pre- and post-monsoon average groundwater depths of different blocks in Kurukshetra district, Haryana, India. The stochastic analysis of groundwater depth was carried out using auto regressive integrated moving average (ARIMA) model. Best-fitted models ARIMA (2, 1, 1) and ARIMA (0, 1, 2) were used for prediction of pre- and post-monsoon groundwater depth fluctuations up to the year 2020. Results indicate that by the year 2020, average groundwater depth in the pre- and post-monsoon seasons in the district is expected to decline by 5.63 and 5.72 m respectively, over the base year 2010. Results of this study will be helpful in evolving strategies for groundwater development and management.

Abstract

Experiment was conducted using weighing-type field lysimeters to determine single and dual crop coefficients (K_c) and to estimate water productivity of mustard (Brassica juncea) cultivar, Pusa Vijay (NPJ-93) during rabi 2013-14 and 2014-15. It was observed that the single crop coefficient (K_c) during rabi 2013-14 was 0.39, 0.72, 1.02 and 0.5 for initial, development, mid and late stages respectively. While in dual Kc the value of K_cb (basal crop coefficient) was 0.19, 0.55, 0.91 and 0.24 for the four stages, respectively. During rabi 2014-15, the single Kc was 0.36, 0.63, 1.04 and 0.44 and for dual K_c the value of K_cb was 0.17, 0.46, 0.91 and 0.23 for four stages respectively. Relationship between K_cb and leaf area index as well as between K_cb and growing degree days was also established. Water productivity was estimated to be 14.9 kg/ha-mm corresponding to grain yield of 2.34 t ha^-1 with 157 mm of total irrigation water applied during rabi 2013-14. Whereas during rabi 2014-15, water productivity was 15.4 kg/ha-mm with grain yield of 2.89 t ha^-1 with 187 mm depth of applied irrigation. Nonetheless, the estimated crop coefficients of mustard can be used for judicious irrigation scheduling in order to enhance water productivity in semi-arid environment.

Abstract

Normally groundwater recharge is estimated using methods based on water balance, water table fluctuations, fixed factor of annual rainfall and tracer movement. In many of these methods water stored in the vadose zone and evapotranspiration are not accounted properly. These factors control groundwater recharge to a large extent, particularly in arid and semi-arid regions which are normally characterized by a deep water table, thick vadose zone and high evapotranspiration. In this study, HYDRUS-1D and MODFLOW models were used to assess the recharge flux and groundwater recharge in an area under a semi-arid region giving due consideration to important vadose zone processes. Cumulative recharge flux at water table in various sub-areas varied from 20.01 cm to 23.43 cm (29.26% to 34.26% of the monsoon rainfall). The average groundwater recharge was 22.2%. Total surface runoff in various sub-areas varied from 3.39 cm to 14.36 cm (5% to 21% of the monsoon rainfall). Evapotranspiration was found to be a major recharge controlling factor. Reference evapotranspiration varied from 37.19 cm to 45 cm (54% to 66% of the monsoon rainfall). Natural recharge under the prevailing pumping rate and pumping schedule was 23.3% of the monsoon rainfall. Simulation results revealed that if all the surface runoff is retained in the area, water table will rise by 1.46 m.

Abstract

In the present study we estimate the velocity and thickness of the Patseo glacier, Himachal Pradesh, India. The average velocity of the glacier was estimated as ~5.47 m/year using co-registration of optically sensed images and correlation (COSI-Corr) method. The glacier thickness was found to vary between 12 and 278 m, with an average value 59 m. The total glacier ice volume was estimated as ~15.8 × 10⁷ m³, with equivalent water reservoir of ~14.5 × 10⁷ m³. Ground penetrating radar (GPR) surveys were conducted during 2004 and 2013 for validation of the estimated glacier thickness. The glacier thickness estimated using COSI-Corr method was found to be in agreement with GPR-retrieved glacier thickness (RMSE = 4.75 m; MAE = 3.74 m). The GPR profiles collected along the same geographic locations on the glacier during 2004 and 2013 showed a reduction in ice thickness of ~1.89 m, and thus resulting in an annual ice thickness decrease of ~0.21 m. The glacier area was estimated for 2004 and 2013 using LISS IV satellite data and found to be ~2.52 and ~2.30 sq. km respectively. This shows an annual reduction of ~0.024 sq. km in glacier area. The total annual loss in glacier ice volume was estimated as ~4.55 × 10⁵ m³. This loss in the glacier ice volume of the Patseo glacier is supported by the snow and meteorological observations collected at a nearby field observatory of Snow and Avalanche Study Establishment (SASE). The climate data collected at SASE meteorological observatory at Patseo (3800 m), between 1993–94 and 2014–15 showed an increasing trend in the mean annual temperature and a decreasing trend in winter precipitation.

Abstract

In this study impact of climate change on groundwater recharge is investigated and the carbon emission from groundwater irrigation is assessed under projected climate change scenarios for Karnal district of Haryana state in India. HYDRUS-1D and MODFLOW models were used to simulate the climate change impacts on groundwater recharge for different projected climate change scenarios. Simulation results showed that groundwater recharge would increase marginally by 2030 over the baseline year of 2008 under the scenario based on ARIMA predictions, which considered the effect of all climate parameters. However, under the scenarios, which considered only rise in temperature, groundwater recharge would decrease by 0.07–0.22 m. Rise in temperature by 3.5°C and 4.3°C along with 9% and 16% increase in rainfall over the base year would increase the recharge by 0.09 m and 0.14 m respectively. The study also revealed that the effect of climate change on cumulative recharge would be more in sugarcane fields than in rice fields. Carbon emission of groundwater irrigation under the scenarios based on rise in temperature only would increase by a minimum of 12 kg CO₂/ha in pearl millet crop by the year 2030 to a maximum of 3250 kg CO₂/ha for sugarcane crop by the end of this century. Estimated total carbon emission in 2030 would be 345,857 metric tonne from groundwater irrigation in Karnal district which is 87,474 metric tonne more than the baseline emission.

Abstract

This article analyses the blue, green and grey water footprints and virtual water flows within the Gomti river basin (GRB) in India. Assessments were made at spatial resolution of agricultural production units (APUs). An APU is a homogeneous spatial unit delineated on the basis of soil type, agro-ecological region and district boundaries. Water footprints of crop production and consumption were compared to arrive at virtual water balance within the GRB. Results show that water footprint of GRB was 12,773 million m³ year^–1. Crop production was the largest water consumer accounting for 95.5% of water footprint within the basin. The higher proportion of blue water footprint (47.3%) indicates the dependence of GRB on irrigated agriculture. Contribution of rainfed agriculture to total water footprint was about 11.2%. Considerable portion of blue water is used in the production of low value water-intensive crops. The GRB was assessed as a net virtual water importer, indicating its dependence on the water resources of other river basins; it imports 2945 million m³ virtual water annually. This scenario can be changed if the area allocated to different water-intensive crops is optimized and limited to the extent that meets the consumption needs within the basin, leading to reduction in production surplus of these crops.

Abstract

An avalanche accident was occurred on 5 January 2018 on Chowkibal–Tangdhar road in Kupwara district, Jammu and Kashmir about 6 km from Chowkibal village. One light passenger vehicle was swept away in the avalanche and 10 persons lost their lives. In this communication, we study the cause of avalanche accident and simulate the snow avalanche flow using Rapid Mass MovementS model. Total snow depth recorded at the nearest observation location from the accident site was 31 cm and fresh snow of the storm was 24 cm. Avalanche condition on slope was building up and the Snow and Avalanche Study Establishment issued an avalanche warning of ‘Low Danger’ for the Chokibal–Tangdhar road axis. Maximum thickness of avalanche debris on road was observed to be 3.0 m. Flow simulation showed maximum velocity of avalanche to be ~25 ms^–1, maximum impact pressure ~9.39 × 10⁴ kg m^–1 s^–2 and maximum height of avalanche flow ~3.0 m.

Abstract

This study analyses the drought events for the Gomti basin in Uttar Pradesh (UP), India using the standardized precipitation index (SPI) at the spatial and temporal scales. Daily precipitation data for 14 districts in the Gomti basin for 41 years (1971–2011) were used to calculate the SPI for 1-month, 4-month, 6-month and 12-month time scales. Results for the 6-month (June–November) and 12-month time scales were similar and drought years were observed in 1972, 1979, 1987, 1993, 1994, 2002 and 2010. The 4-month SPI was analysed for the main monsoon months in the Gomti basin, i.e. from June to September. Results showed that significant drought occurred during the monsoon months of 1979, 1987, 1993, 2002, 2009 and 2010. For drought analysis at the spatial scale, the Kriging interpolation method available in ArcMap was used. The 12-month SPI showed that the frequency of severe and extreme drought was more in the upper regions of the basin during 1971–2000 whereas drought frequency was more in the central and lower regions of the basin during 2001–2011. Further, the de Martonne aridity index was calculated for the period 1971–2007 and its correlation with the 1-month SPI for the period 1971–2007 was evaluated.

Abstract

A field experiment was conducted for two consecutive years to develop management alternatives for wheat cultivars (salt-tolerant and salt non-tolerant) cultivated under irrigated saline environment (groundwater, 4, 8 and 12 dS m^–1) and foliar potassium fertigation. The grain yield of wheat cultivars decreased with the increase in salinity levels of irrigation water. The foliar potassium fertigation during the heading stage of wheat cultivars ameliorated the adverse effect of salinity and resulted in the increase in grain yield. In this study, empirical equations for wheat yield known as production function have been developed. The production functions were developed keeping grain yield parameter as output, besides the many input parameters pertaining to quantity and quality of the irrigation water, quantity of potassium applied as foliar spray and rainfall depth during the crop growth period. The production function with higher coefficient of determination (R²) may be used to predict grain yield of both salt-tolerant and salt non-tolerant cultivars under different saline irrigation regimes, rainfall and irrigation water depths, besides the dose of potassium sulphate (K²SO₄) for foliar spray. The production function which gave the highest R² value (i.e. 0.82 for KRL-1-4 and 0.97 for HD 2894 wheat cultivars) could be used for foliar spray under different salinity regimes with high expectation of grain yield. The predicted grain yield and estimated quantity of potassium under different salinity levels of irrigation water may prove useful to different stakeholders for enhancing the wheat yield in high saline water areas. The stakeholders can predict the grain yield under similar circumstances as explained in this experiment and estimate the appropriate potassium doses to be applied for enhancing the wheat yield.

Abstract

Accurate quantification of reference crop evapotran-spiration (ETo) plays a significant role in determining crop water requirements in irrigated agriculture. A plethora of methods for the estimation of ETo are available. However, the regional suitability of these methods needs to be assessed given the limited availa-bility of meteorological data. In this study, daily estimates of 11 ETo models were selected and compared with the FAO-Penman–Monteith equation (FAO-PM). The select-ed methods were Blaney–Criddle (BC), Jaisen–Haise (JH), Hargreaves method (HM), McGuinness–Borndne (MB), Chapman (CM), Abtew model (AM), Turc method (TM), FAO-PM equation, Penman equation (PM), Prie-stley–Taylor (PT) and Matt–Shuttleworth (MS). Evalua-tion of these models was carried out during 2016–20 in the New Bhupania Minor Command of the Dulhera dis-tributary, Western Yamuna Canal Command (WYCC), Haryana, India. The selected models were evaluated to find a substitute for the FAO-PM equation based on different statistical indices. It was observed that the PT method performed best and was in line with the FAO-PM equation with correlation coefficient, root mean square error, mean absolute error, Nash–Sutcliffe co-efficient and mean bias error as 0.92, 0.74, 0.48, 0.83, 0.171 respectively. Based on this study and statistical error indices values, the models can be ranked as PT > CM > TM > JH > AM > PM > MS > HM > BC > MB. Thus, we recommend using the PT model for the esti-mation of ETo in the study area with available meteoro-logical parameters for irrigation scheduling.

Abstract

Hydroponics is emerging as a beneficial technique to augment food production in which the quality and yield of a crop are improved by accurately maintaining the desired electrical conductivity (EC), pH and dissolved oxygen (DO) in the nutrient solution. This article describes the development of an automatic control system for mint cultivation in hydroponics that consists of EC, pH, and DO sensors which continuously monitor the respective parameters and control their value in nutrient solution with the help of microcontroller and actuators. The developed system maintained the EC, pH and DO of the nutrient solution within their desired limits of 2.0–2.5 dS m^–1, 6.0–6.5 and above 8 ppm respectively. The plant height, average leaf area per plant and total chlorophyll content of the mint plants varied between 18.9–20.3 cm, 15.69–18.45 cm² and 23–30 (SPAD units) respectively. The results of this study emphasize the system’s effectiveness in monitoring and controlling the parameters of the nutrient solution thereby maintaining favourable growth conditions in the hydroponic cultivation of mint.
